VPA catalytic reaction for the removal of small air separation unit

Gases obtained from coal as raw material may contain large amounts of carbonyl sulphur cos content too high (e.g. >20ppm) into the PSA small air separation unit will affect the quality of the product and the service life of the adsorbent molecular sieve. Common desulphurising agents are less effective in removing cos at room temperature, high temperature desulphurising agents (e.g. ferromanganese desulphurising agents) can be converted to absorb cos, and high temperature catalysts (e.g. cobalt-molybdenum catalysts) can convert cos into easily removable H2S, which require an operating temperature of 300°C or more, with high energy consumption and can cause 'hot and cold disease' in the process. ℃) + room temperature iron oxide desulphurisation agent combination process, can completely solve this problem. That is, the hydrolysis into at low temperature, and then the removal of room temperature iron oxide desulphurization agent, can be reduced to 1 ppm in the raw gas cos before entering the variable pressure adsorption device in small air separation unit.

In case of sudden power failure during the operation of small air separation unit, the following steps should be followed:   First, open the vent valve (anti surge valve) of air compressor to prevent the air compressor from surging and causing the air compressor to reverse due to air backflow;   Then check whether the molecular sieve adsorber switch should be interlocked to close, if not, it should be man...
