Automated process control system for a combined electrical desalting and atmospheric distillation unit UPN-100A (AT-1), UPN-100B (AT-2)
Development: May 2022 – July 2022.
Works performed:
Inspection of the facility, collection of initial data
Project development including development of detail design documentation
Development of application software for PLC and SCADA
Hardware and software main specifications: The automated process control system has a three-level structure:
The structure is implemented as a three-level hierarchical system.
The upper level is a human-machine interface.
HMI is based on WinCC software. The system includes the following operator workstations: Operator workstation (OS Station 1...6);
The middle level is implemented on the basis of Simatic S7 CPU-410-5H programmable logic controllers and a set of SIMATIC ET200M subsystem I/O devices.
The lower level (field level) includes sensors, secondary measuring transducers, actuators, etc.
Project description:
The project involves complete replacement of the existing automated process control system of the atmospheric distillation units with integration into the automated process control system of Tomskneftepererabotka LLC.
