Several issues with synthesis
Thread Content
1. Synthesis system, cooled by natural water convection. Is it necessary to shut down the system again during an emergency shutdown? Why? 2. For a synthesis system, what pressure level is an appropriate estimate to use when it is operating at 1/4 load? This pressure can be controlled. Full load 7MPA
I don’t quite understand what you mean by the first question. Answering only the second question: The pressure control at a quarter load depends on the minimum flow rate indicated on the turbine’s performance curve at that load, in order to prevent the turbine from experiencing surge. If the pressure is too high, the turbine is prone to surge; if the pressure is too low, the flow rate of the vent gas increases, resulting in greater losses. Personal opinion, for reference only.
Compared to fresh gas, using 1/4 of fresh gas and a normal circulation ratio of 1/5, what would be the circulation ratio in this case? Does anyone have any relevant experience?
