Paper Title
Consequence Modeling And Evaluation Of Export Gas Unit Of Gas Refinery

Abstract
Oil and gas related production, storage, processing, transmission and distribution infrastructure has, in general, a good safety record, but the possibility of accidents can never be discounted. Of primary concern is the accidental release of flammable or toxic material from pipe work, vessels and other equipment, which can affect personnel in the immediate vicinity and surrounding populations. The released material can be in the gaseous or liquid phase (including natural gas in its liquid form – LNG), flammable or toxic. In addition, there are circumstances where planned operations (e.g. flaring) have the potential for harm and need to be assessed accordingly. Consequence modeling is needed to understand the potential for harm of the many and varying release scenarios for operations in the oil and gas and chemical process industries.Export of gas to another units need to pressurize it. This purpose is obtained by using sets of compressors and their connective pipelines. Any leakage or failure has potential to create a fire or explosion. The main objective of this article is to study the consequences of gas dispersion and its results in Export Gas Compression unit (106) from Gas Refinery of South Pars Gas Field in Persian Golf . The effect of three scenarios (gas dispersion, jet fire, explosion.) is analyzed and plotted. PHAST software v. 6.53.1 software was used for performing the simulations.
