Refinery Automation System

Introduction

Oil refinery automation system is intended for automation of crude oil atmospheric distillation processes to residual, diesel and gasoline fractions, and their shipment to customers.

Scope of Automation

The system provides monitoring and control for the following oil refinery facilities:

  • Crude oil preheater;
  • Fractionation towers and heat exchangers;
  • Pump station;
  • Tank farm for crude oil and finished products;
  • Chemical agents reservoir;
  • Terminal compressor station;
  • Loading racks;
  • Emergency and drain tanks;
  • Other processing facilities.

Main Features

The system provides the following functionality:

  • Automatic monitoring of all process parameters and equipment status parameters;
  • Automatic protection of process equipment in case monitored parameters reach emergency and ultimate values as well as in case of support system failure;
  • Maintenance of standard operation modes;
  • Stop valves control;
  • Programmable control and protection of pump units;
  • Process parameters control;
  • Visualization and registration of the main process variables and parameters characterizing equipment condition during normal operation, maintenance and commissioning;
  • Generation of reports;
  • Logging of events.

The refinery automation system is realized using a set of programmable logic controllers (PLC) and distributed control architecture.

Benefits

  • Flexibility

The refinery automation system can be completed by modules allowing solving different automation tasks. The system is designed to ensure scalability in hardware and functionality to adapt to growing customer requirements better integration with third party systems.

  • Functionality

The system components provide for additional operation modes (simulation, testing and masking) and other features, such as unauthorized access protection and event logging to monitor personnel actions.

  • Compatibility

Open standards ensure compatibility with many equipment and third-party automation systems.

  • Quality guarantee

The system has all the necessary Rostehknadzor certificates and permits for use.
