Hardware and software complex for data exchange between the System for oil quantity and quality accounting of Baltnefteprovod and Kirishi Oil Refinery

Customer: Kirishi Oil Refinery
Project designer of hardware and software complex: SPIK SZMA (St.Petersburg)
Project designer of oil quantity and quality accounting operations and reporting generation: Nauka, Technology, Informatics, Control (LLC NAUKA, St.Petersburg).

System purpose:
Data exchange between the System for oil quantity and quality accounting (SOQA) of Baltnefteprovod and process & enterprise control system servers of Kirishi Oil Refinery.

System specification:
Data exchange information system between oil accounting station of LLC Baltnefteprovod and crude oil tank of Kirishi Oil Refinery. Based on SCADA InTouch (Wonderware), including:

1. Operator working station connected via network switch through Ethernet interface to LAN of oil accounting station. The second Ethernet interface is used to connect to the enterprise control system of Kirishi Oil Refinery. Operator working station receives real time data from SOQA station and communication server through LAN using OPC DA 2.0 protocol. Information is viewed at screen displays representing oil accounting station units and crude oil tank. Pipelines, tanks, shutoff valves, pumps etc. are displayed. Area for process messages and emergency alarms is provided.

2. Accounting working station connected via network switch through Ethernet interface to LAN of oil accounting station. The second Ethernet interface is used to connect to the enterprise control system of Kirishi Oil Refinery using the network devices installed in the communication panel.

3. Communication server connected via network switch through Ethernet interface to LAN of oil accounting station. The second Ethernet interface is used to connect to the enterprise control system of Kirishi Oil Refinery using the communication devices installed in the communication panel.


Information functionality:

Operator working station:
1. Status monitoring of the oil accounting station equipment:
status (RUN) of pump motors;
status (OPEN/CLOSE) of valve gates with electric drive;
status (FAILURE) of valve gates with electric drive;
opening rate of the valves of flow regulators.

2. Monitoring of actual process values of the oil accounting station (with alarming on process values out of range):
oil temperature in quality control unit and in each metering unit line;
oil pressure in quality control unit and in each line at input and output of the metering unit;
oil pressure differential in each metering unit line;
oil flow in the quality control unit and in metering unit lines;
oil density, viscosity, moisture content.

3. Emergency alarming:
gas concentration in the operator room and in the quality control area;
fire in the operator room and in the quality control area.

4. Status monitoring of the crude oil tank farm:
status (OPEN/CLOSE) of valve gates with electric drive;
status (OPENING, CLOSING, FAILURE) of valve gates with electric drive;
status (RUN) of pump motors;
low level at the pump intake.

5. Monitoring of actual process values of the crude oil tank farm (with alarming on process values out of range):
oil pressure at pump output;
oil consumption supplied to the units;
oil temperature supplied to the units;
oil pressure in supply pipelines;
product consumption in tanks;
temperature, level and volume of product in tanks.

6. Data exchange with SOQA working station and communication server.

7. Alarming on failures detected by self-diagnosis, including data exchange failure.

Accounting working station:
1. Reading information from text csv-files of archive data exchange generated by the operator station.
2. Displaying of oil flow values for two hours (total by lines).
3. Displaying of oil temperature and density for two hours (average by lines).
4. Displaying and editing oil flow and temperature values in tanks generated by ENRAF metering system, and oil density in tanks proceeding from laboratory test results.
5. Confirmation of the oil supply with level measuring in tanks and flow values received from SOQA station.
6. Calculations of shift and daily balance values of the oil tank farm.
7. Printing out of real time value sheets and balance results.
8. Reporting generation:
reference on routing commissions;
act on product left;
reference on raw material supply via pipelines;
reference on raw material delivery for production.
