SONATRACH RAFFINERIE D’ALGER, Algiers Refinery Algeria (OWNER) is presently operating a 2.7 MMTPA petroleum refinery at Algiers, Algeria having various units such as Crude Distillation Unit, Gas Plant, Catalytic Reformer unit and associated auxiliary units including utility & offsite. The plant is situated at Sidi-Arcine, located east of Algiers Refinery, and is approximately 10 km from Algiers Airport and 15 km from the Algiers Port. Algiers Refinery was built in 1964 with a capacity of 1.6 MMTPA for processing of Hassi Messaoud crude oil. Capacity of Algiers Refinery was increased to 2.7MMTPA in the year of 1970. As part of “Rehabilitation & Adaptation Project” of Algiers Refinery, OWNER intends to revamp some of the above units and also add a few new units. Engineers India Ltd. (EIL), New Delhi, INDIA has been retained as PMC by SONATRACH for Rehabilitation & Adaptation Project of Algiers Refinery. Under the Rehabilitation Project, the crude processing capacity of the Refinery shall be increased by 35%. The revamp of existing units in the refinery and associated Utilities and Offsite facilities shall be enhanced / modified under Rehabilitation part. OWNER has also planned to produce fuels conforming to the Euro-2009 specifications. Accordingly, OWNER has planned to implement a project under Rehabilitation part to increase the capacity from the complex including modernization of existing utilities and offsite facilities. Electrical modernization and Instrument modernization including new DCS and central control room are also part of Revamp plan. Under the Adaptation project SONATRACH intends to maximize diesel and minimize fuel oils. For this matching new Utilities, Offsite facilities and an Effluent Treatment Plant (ETP) with Biological treatment plant to cater to the requirement of the refinery have been planned. New Residual Fluidized Catalytic Cracking Unit (RFCCU), Sulfur Block containing Sulfur Recovery unit (SRU), Amine treatment Unit (ARU), Sour water stripper unit (SWS), Fuel Gas treating unit (FGATU) and a new MS Block containing Naphtha Hydrotreater unit (NHTU), Light Naphtha Isomerisation Unit (LNISOM),Continuous Catalytic regeneration Unit(CCRU) have also been planned under the Adaptation Project. Under instrumentation modernization work, all existing pneumatic instruments in existing plants, revamped or otherwise, shall be replaced with electronic instruments with all associated accessories. A central control room (blast resistant) shall be replaced with a new DCS control system which will control, monitor the Refinery. Both Rehabilitation and Adaptation area plants, Utilities and Offsite have been planned along with a number of Satellite rack rooms. Fire and gas detection and monitoring system of the refinery is also part of Project. Under electrical modernization work, a new 63 kV grid power reception and distribution terminal along with a number of new and revamp of substations have been envisaged. This will also include addition and replacement of existing transformers, switchgears etc. New plant communication, Fire alarm, telephone systems in plant and few of non plant buildings are also part of the Project. As part of Fire water system up gradation, a new fire water network along with pump station and other fire water systems like foam, water monitors have been planned.

ELECTRICAL/INSTRUMENTATION INTERFACE CONDUITS
CONDUIT DCE-A / DCE-B Conduit in between equipment supplied the LV vendor (DCE) and Invensys (DCS).
This conduit is dedicated to the exchange data in between the Data Concentrator Electric (DCE) and the DCS. This link is redundant, therefore the connection is done with the two DCE: DCE-A, mainly dedicated to group the motors of the LV switchgear’s busbar A; and the DCE-B, mainly dedicated to group the motors of the LV switchgear’s busbar SIDE B.
Internal to the Low voltage Switchgear, a MMU (ABB) network is done in such a way that the segment grouping the MMUs of the Switchgear side A is connected at one end to the DCE-A and at the other end to the DCE-B; similarly other segment collects the MMUs of the side B, where one end starts at the DCE-B and the other end is connected to the DCE-A. For further details refer to the document: “Electrical Control System – Architecture Drawing”, 9952T-000-DW-1661-0001.
To ensure reliability and reinforce the redundancy the DCE-A & DCE-B are interconnected in between them.
The typical shown in the general topology (§8) represents a typical LV switchgear. Per each typical a redundant link is considered from the DCS.
The link to the DCS is based on the MODBUS TCP/IP protocol over Ethernet. The physical media is based in a single mode optical fiber from the DCE up to the FOP (fiber optic panel), and then converted to Ethernet UTP cable to reach the Ethernet termination card on the DCS.
A preparation meeting and a prototype acceptance test is foreseen to validate the following subjects: 9 Protocol 9 Data packaging and format (single precision-floating, integers, coils, bits, etc.) 9 Contiguous registers, to improve the scanning cycle. 9 Redundancy type 9 Speed 9 Physical media, evaluate need of converters. 9 IP addresses 9 Heartbit implementation, function code 8 9 Communication disruption strategy to be adapted to the electrical equipment under operation.

HARDWIRED CONNECTION Some motors typicals uses the hardwired type connection in between the DCS/ESD,PLCs and the MCC.
Generally the ESD commands, Variable speed settings to the VSDS and PLCs and other third controllers (different to the ESD, DCS) commanded motors’ signals are interfaced by hardwired cables per each signal. Similarly for the HV motors’ feedbacks and commands, the interfaces are hardwired. The identification “package” will be used to consider the: PLCs, Mark VI, standalone controllers, Electrical Heaters equipped with thryristors, etc.

ELECTRICAL/INSTRUMENTATION INTERFACE TO ELECTRICAL HEATERS
10.1
SCOPE The electricals heaters can be of two different types: Coils operated by loading thyristors, which allow temperature variation by modulating the power. Coils simply powered by a nominal power, no modulation.
Even when based on the same signals as the conduits already explained, different typicals were defined to represent the signals being exchanged. These typicals can be seen in the following drawings: 9952T-000-PID-0090-0026/0027/0028.
Generally the control panels for the Thyristors powered heaters are supplied loose and installed in the electrical substation, including and electronic modulating circuit top trgger the thyristors, the respective terminals strip to interface the control sources signals from the DCS or Packages (PLCs, other standalone controllers). The nominal electrical heaters are simply powered by a MCC.
Special care shall be taken for the analog signals being exchanged, like: current measurements. The DCS or Package, powers in 4-20 mA @ 24 VDC the loop, therefore the heaters current device shall be passive. If it is not the case, the Heater panel shall be equipped with isolator for the concerned signals.
The interface to the “nominal” powered heaters can be software or hardwired. If interfaced with the DCS, mainly software; if interfaced with packages, hardwired.
The interface with the thyristorized heaters is fully hardwired.

Algiers Refinery was built in 1964 with a capacity of 1.6 MMTPA for processing of Hassi Messaoud crude oil. Capacity of Algiers Refinery was increased to 2.7MMTPA in the year of 1970. As part of “Rehabilitation & Adaptation Project” of Algiers Refinery, OWNER intends to revamp some of the above units and also add a few new units. Engineers India Ltd. (EIL), New Delhi, INDIA has been retained as PMC by SONATRACH for Rehabilitation & Adaptation Project of Algiers Refinery. Under the Rehabilitation Project, the crude processing capacity of the Refinery shall be increased by 35%. The revamp of existing units in the refinery and associated Utilities and Offsite facilities shall be enhanced / modified under Rehabilitation part. OWNER has also planned to produce fuels conforming to the Euro-2009 specifications. Accordingly, OWNER has planned to implement a project under Rehabilitation part to increase the capacity from the complex including modernization of existing utilities and offsite facilities. Electrical modernization and Instrument modernization including new DCS and central control room are also part of Revamp plan. Under the Adaptation project SONATRACH intends to maximize diesel and minimize fuel oils. For this matching new Utilities, Offsite facilities and an Effluent Treatment Plant (ETP) with Biological treatment plant to cater to the requirement of the refinery have been planned. New Residual Fluidized Catalytic Cracking Unit (RFCCU), Sulfur Block containing Sulfur Recovery unit (SRU), Amine treatment Unit (ARU), Sour water stripper unit (SWS), Fuel Gas treating unit (FGATU) and a new MS Block containing Naphtha Hydrotreater unit (NHTU), Light Naphtha Isomerisation Unit (LNISOM),Continuous Catalytic regeneration Unit(CCRU) have also been planned under the Adaptation Project. Under instrumentation modernization work, all existing pneumatic instruments in existing plants, revamped or otherwise, shall be replaced with electronic instruments with all associated accessories. A central control room (blast resistant) shall be replaced with a new DCS control system which will control, monitor the Refinery. Both Rehabilitation and Adaptation area plants, Utilities and Offsite have been planned along with a number of Satellite rack rooms. Fire and gas detection and monitoring system of the refinery is also part of Project. Under electrical modernization work, a new 63 kV grid power reception and distribution terminal along with a number of new and revamp of substations have been envisaged. This will also include addition and replacement of existing transformers, switchgears etc. New plant communication, Fire alarm, telephone systems in plant and few of non plant buildings are also part of the Project. As part of Fire water system up gradation, a new fire water network along with pump station and other fire water systems like foam, water monitors have been planned.

ELECTRICAL/INSTRUMENTATION INTERFACE CONDUITS
CONDUIT DCE-A / DCE-B Conduit in between equipment supplied the LV vendor (DCE) and Invensys (DCS).
This conduit is dedicated to the exchange data in between the Data Concentrator Electric (DCE) and the DCS. This link is redundant, therefore the connection is done with the two DCE: DCE-A, mainly dedicated to group the motors of the LV switchgear’s busbar A; and the DCE-B, mainly dedicated to group the motors of the LV switchgear’s busbar SIDE B.
Internal to the Low voltage Switchgear, a MMU (ABB) network is done in such a way that the segment grouping the MMUs of the Switchgear side A is connected at one end to the DCE-A and at the other end to the DCE-B; similarly other segment collects the MMUs of the side B, where one end starts at the DCE-B and the other end is connected to the DCE-A. For further details refer to the document: “Electrical Control System – Architecture Drawing”, 9952T-000-DW-1661-0001.
To ensure reliability and reinforce the redundancy the DCE-A & DCE-B are interconnected in between them.
The typical shown in the general topology (§8) represents a typical LV switchgear. Per each typical a redundant link is considered from the DCS.
The link to the DCS is based on the MODBUS TCP/IP protocol over Ethernet. The physical media is based in a single mode optical fiber from the DCE up to the FOP (fiber optic panel), and then converted to Ethernet UTP cable to reach the Ethernet termination card on the DCS.
A preparation meeting and a prototype acceptance test is foreseen to validate the following subjects: 9 Protocol 9 Data packaging and format (single precision-floating, integers, coils, bits, etc.) 9 Contiguous registers, to improve the scanning cycle. 9 Redundancy type 9 Speed 9 Physical media, evaluate need of converters. 9 IP addresses 9 Heartbit implementation, function code 8 9 Communication disruption strategy to be adapted to the electrical equipment under operation.

CONDUIT ECS-A / ECS-B Conduit in between equipment supplied the ECS vendor (ECS controllershub) in the CCR and Invensys (DCS).
This conduit is dedicated to the exchange data in between the Electrical Control System (ECS) data concentrator and the DCS. This link is redundant; therefore the connection is done with the two ECS controllers in the CCR:.
The typical shown in the general topology (§8) represents a typical HV switchgear. Per each typical a redundant link is considered from the DCS.
The link to the DCS is based on the MODBUS TCP/IP protocol over Ethernet. The physical media is based in a single mode optical fiber from the ECS up to the FOP (fiber optic panel), and then converted to Ethernet UTP cable to reach the Ethernet termination card on the DCS.
A preparation meeting and a prototype acceptance test is foreseen to validate the following subjects: PP 1 - ANG - rev. 2

CONDUIT DCE-VSDS-A / DCE-VSDS-B Conduit in between equipment supplied the VSDS vendor and Invensys (DCS).
This conduit is dedicated to the exchange data in between the Data Concentrator Electric (DCE) VSDS and the DCS. This link is redundant, therefore the connection is done with the two DCEVSDS: DCE-VSDS-A, mainly dedicated to group the motors of the LV switchgear’s busbar A; and the DCE-VSDS-B, mainly dedicated to group the motors of the LV switchgear’s busbar B.
Internal to the Low voltage Switchgear, a VSDS network is done in such a way that the segment grouping the VSDSs of the Switchgear side A is connected at one end to the DCE-VSDS-A and at the other end to the DCE-VSDS-B; similarly other segment collects the MMUs of the side B, where one end starts at the DCE-VSDS-B and the other end is connected to the DCE-VSDS-A. For further details refer to the document: “Electrical Control System – Architecture Drawing”, 9952T000-DW-1661-0001.

To ensure reliability and reinforce the redundancy the DCE-VSDS-A & DCE-VSDS-B are interconnected in between them.
The typical shown in the general topology (§8) represents a typical LV switchgear. Per each typical a redundant link is considered from the DCS.
The link to the DCS is based on the MODBUS TCP/IP protocol over Ethernet. The physical media is based in a single mode optical fiber from the DCE up to the FOP (fiber optic panel), and then converted to Ethernet UTP cable to reach the Ethernet termination card on the DCS.
In case that only one VSDS is present in switchgear, then the concentrator switch will not be used, and the VSDS will directly linked to the DCS, with no redundancy. The ESD trip remains hardwired. 9.3.1

HARDWIRED CONNECTION Some motors typicals uses the hardwired type connection in between the DCS/ESD,PLCs and the MCC.
Generally the ESD commands, Variable speed settings to the VSDS and PLCs and other third controllers (different to the ESD, DCS) commanded motors’ signals are interfaced by hardwired cables per each signal. Similarly for the HV motors’ feedbacks and commands, the interfaces are hardwired. The identification “package” will be used to consider the: PLCs, Mark VI, standalone controllers, Electrical Heaters equipped with thryristors, etc.

ELECTRICAL/INSTRUMENTATION INTERFACE TO ELECTRICAL HEATERS
10.1
SCOPE The electricals heaters can be of two different types: Coils operated by loading thyristors, which allow temperature variation by modulating the power. Coils simply powered by a nominal power, no modulation.
Even when based on the same signals as the conduits already explained, different typicals were defined to represent the signals being exchanged. These typicals can be seen in the following drawings: 9952T-000-PID-0090-0026/0027/0028.
Generally the control panels for the Thyristors powered heaters are supplied loose and installed in the electrical substation, including and electronic modulating circuit top trgger the thyristors, the respective terminals strip to interface the control sources signals from the DCS or Packages (PLCs, other standalone controllers). The nominal electrical heaters are simply powered by a MCC.
Special care shall be taken for the analog signals being exchanged, like: current measurements. The DCS or Package, powers in 4-20 mA @ 24 VDC the loop, therefore the heaters current device shall be passive. If it is not the case, the Heater panel shall be equipped with isolator for the concerned signals.
The interface to the “nominal” powered heaters can be software or hardwired. If interfaced with the DCS, mainly software; if interfaced with packages, hardwired.
The interface with the thyristorized heaters is fully hardwired.

HARDWIRED SIGNALS TYPE GENERAL
As shown in the topology (refer to §8.1) to execute this interface two cabinets are foreseen: The Interposing panel (IRP), located in the instrumentation’s rackroom. The Elec/Inst Marshalling (EIM) located in the Substation.
The functions of the Interposing panel are to: Collect all the hardwired signals from the different control systems, following a segregation by System (package, DCS, ESD) and type of signal (Digital Input, Digital Output, Analogic and ESD related). Cross wire the signals from the different systems and the multicables landing from the Elect/Inst Marshalling in the Substation.
The functions of the Elec/Inst Marshalling (EIM) are to: Collect all the hardwired signals from the different MCC, in segregated manner, by grouping the: Start/Stop commands, status (available, running and analogics) and ESD related signals. Cross wire the signals from the different systems MCC and the multicables to interface with interposing panel.
