Research on safety requirements of critical safety instrumented function in coke oven gas to methanol process using aspen simulation

As an important part of the protection measures, safety instrumented systems are widely used in process industries, especially in coal chemical industry. The setpoint value and process safety time (PST), which are contents of safety requirements, of the safety instrumented function (SIF) directly affects whether the safety function can correctly protect a specific scenario. In this paper, the setpoint value and PST of the SIF of “low coke oxygen...
