As title: What are the latest energy-saving and emission-reduction measures for dry gas recovery, sulfur recovery, solvent regeneration, and acidic water stripping?
We don’t have the latest energy-saving measures at the moment, but we would be happy to discuss and share them with everyone.
The condensate water from the reboiler of the single-tower low-pressure stripping tower can be used as a heat source at the bottom of the solvent regeneration tower； Purified water can be used as water for the water seal in acidic water tanks and as water for the water seal in lean liquid storage tanks ； Purified water can be used as make-up water for quench towers, etc
If we use the recovery from reciprocating compressors, we can achieve energy savings in those compressors, with good results; the users benefit as well, resulting in a win-win situation for everyone.
Water used for purification often contains oil – does that have any impact on the absorption efficiency?
Purified water is used as feedwater for electrodesalination in atmospheric and vacuum distillation units； Acidic water vapor is introduced in advance into part of the waste alkali solution, thereby achieving the purpose of treating that portion of the waste alkali solution
The condensate water from the reboiler of the single-tower low-pressure stripping tower can be used as a heat source at the bottom of the solvent regeneration tower； Purified water can be used as water for the water seal in acidic water tanks and as water for the water seal in lean liquid storage tanks ； Purified water can be used as make-up water for quench towers, etc ； Can these issues be truly applied in daily production? Are there any uses for them in this regard?
There are two well-applied projects for energy-saving recovery: one is the amine recovery through dry gas demethanization, to ensure that the dry gas does not contain amine; the other is the amine recovery through hydrogen sulfide demethanization, which prevents pipeline corrosion and blockages while also recovering the amine to protect the sulfur conversion catalyst. For your reference
Preventive and predictive replacement of the top condenser in the stripping tower, the tube banks of the feed and product heat exchangers, the top reflux drum, and the trays represents perhaps the most significant savings compared to the reactive approach of fixing problems as they arise and dealing with environmental pollution issues.
