Linde process, low-temperature methanol washing
Thread Content
In low-temperature methanol washing. The right ventricular outlet of the regeneration tower passes through a filter (M3002) and then splits into three streams; two of these streams go to the methanol/water separation tower, while the third stream goes to the left ventricular outlet. May I ask the experienced colleagues why this piping arrangement was chosen? ? Thank you to all the seniors. This post was last edited by wcl_cw3 on 2008-9-6 11:58]
It’s better to post a picture; based on what you’ve described, I can’t figure it out: L
I think what Tata said wasn’t clear either
I’m not entirely sure either; this pipeline should lead to the lean methanol collection tank, I think.
It’s probably to balance the fluid levels in the left and right ventricles! To ensure that the levels on both sides are equal! But I’m not sure why a partition needs to be installed in the middle. Please advise!!
This is a balance pipeline; the methanol in the left ventricle is relatively clean, while that on the right side has a high evaporation rate, so it’s necessary to balance the liquid levels on both sides. The flow is from the left side to the right side. Please reconsider before posting such questions, or clarify the topic – this should not happen again.

The result is that the cleanliness of the methanol on both sides is different; the right side is dirtier
Actually, the answer given on the seventh floor is correct: after passing through the filter, two streams go to the methanol-water separation tower for distillation, while the other stream, which consists of filtered methanol that is relatively pure, returns to the large methanol tank for further reuse.
It’s best to draw a diagram; that way everything will be clear. It’s like solving a puzzle. :o

Of these three, one is located after the tower and before the centrifugal pump; it is connected to the re-burning vessel and serves to balance the liquid levels in the left and right chambers； After filtration by the centrifugal pump, one stream is sent to the methanol-water separation tower for water removal, while the other stream is returned directly to the Poor methanol storage tank; the left and right chambers have different levels of cleanliness and moisture content
