Foaming of the alkaline solution in the LPG desulfurization system

Foaming of the alkaline solution in the LPG desulfurization system can be caused by several factors: 1. Excessive amounts of gases such as hydrogen sulfide and carbon dioxide are present in the alkaline solution; when these gases decompose within the solution, they produce a large number of bubbles, resulting in foaming. 2. Inappropriate operating parameters in the system, such as excessively high or low temperatures, or excessively high or low pressures, can all cause the alkali solution to foam. 3. Mechanical faults in the system, such as uneven mixing or too high mixing speed, can cause a large amount of air to enter the alkaline solution, resulting in foaming of the solution. 4. Quality issues with the alkali solution, such as the presence of impurities in it or improper curing of the alkali solution, can lead to foaming of the solution. To address these issues, solutions can be found by adjusting operating parameters, identifying and eliminating mechanical faults, and improving the quality of the alkaline solution. .

It is likely caused by the excessive duration of alkaline solution reuse, as well as an excess of heavy hydrocarbons, sodium salts, and mechanical impurities; fresh alkaline solution should be replaced promptly
