Linde cryogenic methanol wash
Thread Content
In the Lind process, one line of the recycled flash vapor goes to tower T3003 (the hydrogen sulfide concentration tower), while the other line goes to the feed gas. What is the purpose of going to Tower T3003? I hope the seniors can give me some advice!
That line is generally not very useful; it is mainly used when the flash volume is high in order to reduce the load on the recycle gas compressor
And also, venting at low load
A single pipeline is sufficient for low-load venting and reducing the compressor’s load; why use two pipelines? ? ? Moreover, one went into Tower T3003, and one was vented.
