Installation of the gas-phase outlet separator in the low-temperature methanol wash tower
Thread Content
The separator at the gas-phase outlet of the low-temperature methanol wash tower is installed to prevent liquid from entering the tower and causing problems in subsequent processes. So, are there any good suggestions regarding where the methanol containing liquid should be discharged?
Why not use a carbon-containing methanol flash drum?
Gas-liquid separation after gas condensation? The methanol content in the gas at the top of the scrubber is at most a little over 100 PPM – is it necessary to separate it?
The main concern is large fluctuations in gas volume, high circulation rates, and the presence of liquid
Our company produces methanol and butyl octyl alcohol. The syngas used for methanol production is obtained from a side stream of the washing tower; this stream is equipped with a separation tank. Since complete removal of hydrogen sulfide is only possible in theory, the separated liquid is sent to a sulfur-containing flash tank； If your facility is confident that the desulfurization process can achieve very high cleanliness, it can also be sent to a sulfur-free flash tank
When our plant first started operating, due to poor operational skills, liquid was carried in the purified gas, which caused the synthesis compressor to shut down. A separation tank was added later; once operation stabilized, it basically lost its effectiveness
Our plant has a demister on top of the washing tower
