How to verify the control logic of refined oil stations
Thread Content
I have been working on verifying the control logic for petroleum product stations recently, and I would like to ask how the design institute verifies it after formulating the control logic Is it based on experience or software simulation?
In our area, many of the control logic systems used in oil refineries are quite idealized. The control logic designed for us 10 years ago by a large domestic petrochemical engineering firm doesn’t work well in practice, as many of those logic schemes prove to be unnecessary. The main issues are an overly idealized logic, as well as many problems in actual operation. Some logic design firms need to conduct simulation analyses, such as for the logic design of surge protection. Typically, these firms use specialized software to carry out fluid dynamics analysis of pipelines, and based on the results of these analyses, they determine the logic for surge protection. Conventional control logic, such as that for pumps and valves, is generally well-established based on experience, and there is no need for further verification.
