RESEARCH OF THE PROCESS OF PURIFICATION OF SPENT SULFURIC ACID PRODUCTION OF ACETYLENE (PVC1) AND CAUSTIC SODA (PVC1)
Journal Title: International scientific journal Science and Innovation - Year 2024, Vol 3, Issue 2
Abstract
Currently, there is no universal method for cleaning waste technical sulfuric acid. The technique directly depends on the impurities, volume, and final need, that is, the specific task: why purification is carried out, what needs to be obtained in the end. Also, the concentration of waste sulfuric acid complicates the process with the deposition of organic sediments on the inner surface of the pipes of expensive heaters with subsequent clogging of the pipes. This raises the problem of cleaning pipes from hardened sediments. In addition, organic impurities contribute to the decomposition of sulfuric acid with the formation of gas emissions of sulfur dioxide.
