What are the advantages and disadvantages of using sulfur-containing wastewater for gas enrichment washing water in catalysis?
The purpose of washing rich gas is to remove impurities such as sulfur from the rich gas, thereby reducing corrosion in the absorption and stabilization system. If sulfur-containing wastewater is used as washing water, it will not achieve the purpose of washing if the sulfur content in the wastewater is high. Using purified sulfur-containing wastewater as washing water enables the recycling of wastewater.
The Fe ion concentration and pH value are primarily monitored; if there are no abnormalities, it can be used to reduce the discharge of sulfur-containing wastewater.
Using acidic water can reduce the utility consumption of the facility; of course, using purified water is much better, although it may result in higher costs.
