Synthetic Ammonia Weekly Topics 12/12--12/19: How to handle the gases from the waste oil collector
Thread Content
Weekly Topic on Synthetic Ammonia: How to Handle the Gases from Oil Collectors. How should the gases generated by oil collectors in large-scale units be dealt with? Some are simply vented, while others are recycled. How are they recycled? Please talk about your methods? We welcome everyone to actively participate in the discussions. Participants will receive substantial financial rewards based on the completeness of their answers.
After gas-liquid separation, the gas passes through the oil removal screen and returns directly to the inlet of the low-pressure cylinder.
The vent from the low-pressure side, and the product from the high-pressure side are connected to the purification pipeline for further compression
Our approach is as follows: put it in an oil drum, cover the drum with used quilts or door curtains, then use tape to seal it and apply steam heat to allow any remaining gases and moisture to evaporate. After that, the mixture is allowed to settle, filtered, and sample analysis is conducted; those that pass the tests can be used!
Release directly or discharge to the low-pressure section for recovery
Used oil collector ----- Heating for recovery -------- Release when standards are met
Reply 1# shfuchenko: Generally, it is necessary to collect the gases together; the useful gases released under low pressure are reused in the system, while the waste oil is sent to a storage tank at normal pressure for further treatment.
In our plant, after gas-liquid separation, the gas enters the low-pressure section
After gas-liquid separation on the high-pressure side, it is compressed further for use on the low-pressure side； Direct venting on the low-pressure side,
If it is oil drainage within the system, the vent gas is collected in a separator where the oil is separated; the gas can then be reused by being fed back into the compressor, thereby recovering the useful gas.
