Synthesis system resistance problem
Thread Content
After maintenance, our company’s synthesis system suddenly experienced an increase in the back-pressure (to 0.5 MPa), preventing the system from operating properly. Could anyone please help analyze the cause of this issue?
There are many reasons for resistance; it mainly depends on whether your catalyst has become inactive or if carbon deposition has occurred during startup and shutdown processes – various factors need to be taken into consideration
The question is not clear: is it the resistance from the secondary outlet of the synthesis tower to the waste heat exchanger outlet, or the resistance from the secondary inlet to the waste heat exchanger outlet?
The original poster’s question isn’t very clear; it is recommended that they check the following aspects: 1. Is the system pressure higher than before? 2. Is the resistance of the synthesis tower higher than before? 3. An increase in system resistance needs to be assessed step by step; if the resistance increases overall, then factors such as air volume and the process flow should be considered
