Several challenges regarding pipeline purging in Linde’s low-temperature methanol wash process
Thread Content
The second phase of the company’s project is about to start, and pipeline purging is currently in progress. I would like to ask for advice on how to minimize the use of explosive purging methods when purging the heat exchangers attached to the purified and unpurified scrubbers At present, we are using reverse purging; the hydrogen sulfide scrubber and all the flash tanks have been purged
Original poster, could you share how your hydrogen sulfide scrubbers and various flash tanks are purged?
494131526, add me on Q; I’ll send you our company’s PFD diagrams and then explain the detailed purging process to you
The purging plan for Phase 1 should be the same as that for Phase 2!
There are some changes to the pipelines, and although the purging plans are more or less similar, why go through the extra trouble of following the old methods in areas where simplification is possible? Hehe
