Pressure control of the gasifier
Thread Content
How is pressure control achieved in the gasifier, and where is the pressure control valve installed?
Are there no relevant PID drawings? There should be detailed information there!
Generally, it is installed on the subsequent carbon scrubber tower, with one end connected to the carbon scrubber tower and the other end connected to the flare; it automatically releases gas through the flare in case of overpressure
There is pressure regulation behind the scrubber; when the pressure is too high, it can be released through two vents, and when the pressure is too low, it can be adjusted using the control valve at the syngas outlet
Divide it into several stages: the pressure at the outlet of the washing tower can be adjusted; the pressure at the inlet of the converter can be adjusted once, as can the pressure at its outlet; the pressure at the outlet of the purification unit can also be adjusted once. The inlet pressure of the synthesis compressor can be adjusted once as well. Depending on the requirements for the final stage, i.e., the pressure at the inlet of the synthesis compressor, adjustments can be made sequentially or in stages.
