A new control system was installed at a road handling operation at BP Grangemouth in Scotland. As fuel demands have changed in recent years, the demand for 4 star-premium motor spirit has decreased and there has been a growing demand for unleaded motor spirit (ULMS). BP embarked on a day-tank changeover project, involving pipework and pump changes.
A vapour recovery system was also added to the system which allowed escaping fumes to be collected when tankers were being filled.
In order to integrate the vapour system into the existing control system, Elite Control Systems, suggested upgrading the main PLC with three Siemens profibus drops. Utilising the power line network and using fibre optic cables saved money and time. As the control system is an important feature of the plant a dual redundant system was installed as well. Ewan McAllister, technical director of Elite said: “What we created was a centralised control with remote I/O systems. Everything was controlled from one area, rather than scattered across the whole plant.”
