Abstract:
This study dealing with reduction in gas production due to cold box fouling in ۱۰th refinery of South Pars Gas Complex in Iran well known as South Pars Phase ۱۹. Data comparison has done for timeline periods before and after the refinery annual turnaround. Compelet investigations were done to identify the source of cold box pressure drop in ethane recovery unit and Xylene solvent wash was chosen as aproperiate cure method. A procedure was designed and performed during refinery shutdown time interval. Cold box pressure drop decreased after chemical wash. As a result, the production rate has increased about ۱۸۸ ton/hr for all gas trains with approximately ۳۸۷ million USD/year revenue.
