【Q&A Question 104】April 14, 2017: How are acidic gases treated in the facility? The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) The acid gas from the unit is separated from the reflux tank at the top of the regeneration tower, and the acid gas from the tank’s top is sent via a dedicated line to the sulfur production unit for sulfur recovery. Or simply undergo alkaline washing before being recycled for combustion. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided with detailed explanations; 15–20 Wealth points for correct answers with additional *insufficient* details. Please score according to these criteria. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Petrochemical Sector – “Creative Ideas for Energy Savings” campaign (sponsors sought; highest returns ever) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event organizer.

Build a sulfur plant or a sulfuric acid plant
1. Absorption through solvents (amines, bases, etc.) 2. Cooling technology 3. Biotechnology
Enter the sulfur recovery unit to produce sulfur or sulfuric acid
The sulfur recovery unit recovers sulfur or burns it off in a flare.
Generally, acidic gases are treated in a sulfurization unit
1. Separation is carried out through the reflux tank at the top of the regeneration tower, and then the acid gas from the top of the tank is sent to the sulfur production unit for sulfur recovery. 2. After alkaline washing, recover and burn
Acid gas desulfurization and recovery, or emission at low levels
The acid gas from the unit is separated from the reflux tank at the top of the regeneration tower, and the acid gas from the tank top is sent via a dedicated line to the sulfur production unit for sulfur recovery. Or simply undergo alkaline washing before being recycled for combustion.
