Regarding low-pressure absorption equipment
Thread Content
If the washing section of the low-pressure washer is made taller and more packing is added, will this improve the efficiency of washing and absorption, thereby increasing the concentration at low pressure?
The topic raised by the original poster relates to a renovation project: Different manufacturers have carried out this kind of renovation, but the results achieved were not significant. What the original poster wants is to recycle as much of the unprocessed material as possible. To achieve this goal, as long as the high-pressure system is in good condition at work, there will be no need for a renovation at the low-pressure level. Or, if a renovation is indeed desired, the best approach is to contact relevant CO2 stripping factories that use medium-pressure systems and learn from them. (It may be off-topic, but from the OP’s question it is clear that the goal is to address the losses caused by low/high pressure and poor conversion rates in recovery.)
Increasing the height of the washing section in the low-pressure washer and adding more packing will improve the efficiency of washing and absorption; it will not increase the concentration of the low-pressure absorption liquid, only reducing the ammonia content in the exhaust gas
If the washing section of the low-pressure scrubber is raised and more packing is added, the washing and absorption efficiency will definitely improve. “\"Low-pressure concentration\" refers to the ammonia concentration in the low-pressure scrubber, right? If so, when it is the same as before adding the filler and the original washing effect is poor, the concentration will definitely increase ； If the original washing and absorption performance is already good, it will not increase.
