Alkali washing of salt-containing wastewater in sulfur recovery
Thread Content
What are the causes of blockages in the saline wastewater pipelines of the alkali washing unit, and what are the solutions?
It crystallizes; then we need to examine the properties of the salt that is formed, and maintain an appropriate concentration
It is best to use renewable processes, so as to avoid salt-containing wastewater
Two parameters need to be controlled: temperature and concentration! Salts are easy to crystallize!
The only way is to enhance the displacement; there’s no other method. The solubility of sodium salts is well known
1. The pH value should not exceed 8.3. 2. The oxygen content should be kept as low as possible, at less than 3%, in order to reduce the formation of CO2. 3. The waste discharge volume should not be lower than the designed value
