Propylene and propane recovery; seeking advice
Thread Content
The newly constructed unit generates 400 kg/h of off-gas, whose main components are propylene, propane, and small amounts of ethylene, ethane, hydrogen, water, CO, and CO2. Considering environmental protection and the economic efficiency of the unit’s operation, it is planned to recover and utilize the propylene and propane contained in the off-gas. Is there anyone who knows which domestic company has the relevant technology?
The question is too vague. What kinds of equipment does your company currently have? This small amount can be considered for recycling within existing equipment ； If there are no other devices available, a simple and effective method, considering both investment and operating costs, is to burn them and utilize the heat
There’s a gas holder next, and then another compressor. After compression and condensation, you can either export the gas or distribute it back as return gas. 400kg/h is definitely worth it
Standalone units lack gas separation capabilities; if the gas cannot be recovered, it can only be flared. However, upon recovery, it can be turned into liquefied gas. I simply want to know which domestic companies possess the relevant technology for such recovery.
Design institutes in the oil refining sector handle all design work. There are no patented or exclusive technologies involved; anyone with the necessary qualifications can undertake such work
No special qualifications are required; you can modify it yourself. It’s not complicated. All that’s needed are a gas holder, compressor, condenser, and storage tank. Care should be taken when selecting a compressor.
Gas holder – Compressor – Condenser – Recovery tank – Gas-liquid separation tank – Membrane recovery – Gas holder
