Can an emergency stop be avoided?

Thread Content

I am the shift leader in the purification workshop; due to power restrictions imposed by the transformers, the methanol production system relies on a single 4M32 turbine for operation. This morning, the DCS computer in the decarburization section of our plant’s monolcohol system crashed, causing the programmable valves to close abnormally and preventing gas from being delivered, which led to overpressure in the system. The pressure in the transformation and degassing section surged excessively, leading to overpressure; in this critical situation, I took measures such as venting from the system outlet, performing an emergency shutdown of a single system, and closing the large valves at the system outlet. Dear experts, is there any better way? Appendix: Monohydric alcohol gas process: Gas generation → Desulfurization → Compression 2 outlet → Shift and desulfurization → Decarburization → Final desulfurization → Compression 4 outlet → Crude alcohol synthesis. Shift pressure: 0.8 MPa; operating pressure: 0.65 MPa. Flow rate of fresh synthesis gas: 14,000 cubic meters; operating pressure: 3.8 MPa. The monohydric alcohol system has an annual production capacity of 70,000 tons, while the ammonia synthesis system has an annual production capacity of 80,000 tons.
