Introduction
Integrated tank farm control system is intended for automatic
control over tank farms and oil processing plants production and
raw stock.
Main Features
- collecting data from level meters and pressure gauges about
actual product level in the tank;
- tank field isolating fittings control;
- equipment protection in the case of emergency;
- product parameters calculation according to the certified
algorithms (oil product volume in each tank, total oil product
volume for each grade, volume of free oil tanks, total oil product
mass for each grade);
- creation of reports and summaries about product
transportation;
- calculation of equipment (pumps, dampers) operating time;
- process visualization at the operator's workstation or
panel;
- online and archive logs storing and displaying (for the
specified period) at the operator's workstation and panel;
Scope of Automation
- tanks;
- stop valves;
- pumps.
Structure
The system is designed as a three-level hierarchical system.
Components of the control room level:
- I/O servers with redundancy support;
- tank farm and stock operator workstations.
At the PLC level, PLCs are mounted in front-door control
cabinets. Apart from PLCs, the control cabinets include
intrinsically safe barriers and normalizing transducers.
Components of the filed device level:
- sensors and indicators;
- actuators.
Benefits
The distributed control approach makes devices more intelligent,
allows scalability, provides robustness due to redundancy.
The system supports any types of level meters. It can be
integrated in the commercial fiscal metering system.
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.
Use of open standards ensures compatibility with any device and
any control system. Besides, integration with manufacturing
execution systems is possible.
The system has all necessary approvals and licenses.
