Regarding low-temperature methanol washing of FeS and NiS
Thread Content
It is mentioned in the description of the Linde low-temperature methanol washing process that raw gas is injected into the semi-depleted solution to suppress the formation of FeS and NiS, and pressure elevation is used to cause their formation in specific locations so that they can be removed promptly. ”I don’t understand this paragraph. 1. How is the feed gas injected into the semi-poor solution? 2. Why can it inhibit the formation of FeS and NiS? 3. What are the hazards of the formation of FeS and NiS in the system?
In terms of study*, we don’t have such a configuration; Fes is a dark brown hexagonal crystal that is insoluble in water. It is considered an impurity and must be filtered out
