Seawater Flue Gas Desulfurization and Post-Desulfurization Seawater Recovery

Huge storage tanks of Vinyl chloride monomer (VCM) are often regarded as major hazard installation because VCM is such a kind of flammable, explosive and toxic gas that leakage of liquid VCM would induce fire, explosion and toxic accidents. In this paper, index system of the safety of VCM storage tanks was established by analyzing four main factors including 18 indexes, based on accidents statistic and technology experience. Taking VCM storage tank in a petrochemical plant as a case, AHP-Fuzzy method was applied to achieve single VCM storage tank safety classification. The study could help companies develop preventive measures and emergency planning to reduce casualties and property losses.
