Sulphur handling for Iran’s South Pars gas field

Sandvik Process Systems is to supply the sulphur solidification and handling technology for Iran’s South Pars gas field development. The Iranian South Pars gas field, the northern extension of Qatar’s North Dome field in the Persian Gulf, is estimated to hold reserves in the region of 14 trillion cubic metres. Discovered in 1993 and on-stream since 2002, the field will have a peak annual production of 49 billion cubic metres. The order includes three Rotoform High Speed granulation lines including pumps, filter, preconditioner and cooling water system, delivering a solidification capacity of 800 tonnes per annum. Solidification takes less than ten seconds and the short residence time of the sulphur on the steel belt means there is little time for H2S to escape, resulting in very low emission values. The use of multiple systems allows preventive maintenance to be carried out on individual lines while the other lines remain fully operational.
