| Abstract | v Expansion demand in sulfur recovery processing capacity for refineries and gas plants worldwide is on the rise due to the expansion activities of overall plant capacity; the need for processing more sour crudes; and the tightening of sulfur emissions. WorleyParsons/BOC's proprietary SURE Oxygen Enrichment Technology provides cost effective solutions to this demand. WorleyParsons/BOC's SURE Oxygen Enrichment Technology is a proven technology being employed worldwide. Various configurations and levels of oxygen enrichment are used in these licensed units depending on existing sulfur plant configurations, sulfur processing capacity expansion requirements, plot space available and concentration levels of hydrogen sulfide in the acid gas feeds. Significant operating and capital cost savings are realized in employing SURE Technology in these licensed units which consist of a number of revamped units and some new units. In general, commercially available technologies offer three levels of oxygen enrichment: low-level, medium-level, and high-level providing additional capacity of about 25%, 75% and 150% respectively. All of the existing major equipment can be reused for low-level oxygen enrichment. For medium-level oxygen enrichment a specially designed burner such as WorleyParsons/BOC's SURE direct oxygen injection burner is needed. High-level oxygen enrichment requires the implementation of technology such as WorleyParsons/BOC's Double Combustion SURE process. The process involves the addition of a new reaction furnace burner, reaction furnace and waste heat boiler upstream of the existing equipment. When multiple sulfur trains are involved either a common set of new equipment is shared by the various trains or each sulfur train will have its own set of new equipment. The selection of different oxygen enrichment configurations depends on the overall sulfur plant capacity requirement, desired operating scenario, existing equipment conditions, plot space available and existing facility layout. Details of selecting the optimum oxygen enrichment configuration are discussed in this paper. With the sulfur content of crude oil and natural gas on the increase and with the ever-tightening sulfur content in fuels, the refiners and gas processors will require additional sulfur recovery capacity. At the same time, environmental regulatory agencies of many countries continue to promulgate more stringent standards for sulfur emissions from oil, gas and chemical processing facilities. It is necessary to develop and implement reliable and cost-effective technologies to cope with the changing requirements. In response to this trend, several new technologies are now emerging to comply with the most stringent regulations. These advances are not only in the process technology but also in the manner in which the traditional modified Claus process is viewed and operated. |
