350 TPD SRU designed to take acid gas from amine units as feedstock. The unit uses the Claus process to covert 95% of inlet H2S to element sulfur product of 99.9% purity (dry basis). In the three-bed (3 reactors) SRU process, part of the acid gas is burnt in the main combustion chamber to produce SO2. The gas stream from the combustion chamber is then passed through a series of condensers and reactors to produce liquid sulphur, which is then collected in the sulphur pit and degassed to remove H2S before sending to pastillation unit. The sulphur pastilles from the pastillation unit are stored in silos before sending for export by trucking. The unit was built for a service life of 25 years. After pre-commissioning, it has never been operated. No hydrocarbons or chemicals entered into the unit. Currently the unit is being maintained in preservation mode in a dormant state and ready to start.
