Consequence modeling and analysis of hazardous material dispersion by PHAST software: A Case Study in the South Pars Gas Field Development Phases 15&16

Chemicals used in petrochemical industry are generally comprised of toxic and inflammable substances; they may cause serious problems for humans and environment. To analyse the dispersion of release toxic and flammable material, there are some models like PHAST, ALOHA, SLAB and DEGADIS, but according to the observations and in this article, consequences and conditions of leak of one mixture which is in service at South Pars Gas Field Development (Phases 15&16) is investigated using PHAST software. This paper describes the analysis and results of a PHAST case study of NGL (Natural Gas Liquid) fractionation in the south pars gas field phases 15&16 with three scenarios assumption which are LFL gas dispersion, jet fire and explosion. PHAST version 7.11.33.0 has been used in this work.
