Is pressure relief required in the event of an emergency shutdown of a methanol plant?
Thread Content
The pressure for low-pressure methanol synthesis ranges from 4.0 MPa to 10.0 MPa; is it necessary to relieve pressure in the event of an accident shutdown of the methanol plant?
In the case of an emergency stop, it depends on the type of incident; different approaches should be taken. For ordinary incidents, it is possible to maintain pressure in the methanol synthesis tower
Our unit features a 5 MPa synthesis pressure, a Luchi shell-and-tube design, accident relief systems for heat retention, and after shutdown it maintains heat, pressure, and catalyst temperature, preserving a pressure of 1 MPa. Some promotions failed to relieve pressure, and accidents also occurred, such as the Guohong incident.
