Interlock issue of the catalytic unit regarding flare discharge at the compressor inlet
Thread Content
Is an interlock set to automatically open the flare valve at the compressor inlet? Analysis of advantages and disadvantages
Most units shut down due to air compressor failures, with the inlet opened for flare discharge. It can prevent large fluctuations in pressure.
We don’t have them, but some others do; there are also those with an automatic torch adjustment function
There is a setting for interlocking to automatically open valves to a certain position; manual adjustment of the flare valve position is carried out later on. There are also systems that use size settings to control the pressure at the flare valve; when a certain pressure is reached, the flare valve opens to a specific degree. It is not adjustable in the case of compressor surge.
