Summary:
A survey of the available commercial scavenger technologies, which identifies their process capabilities and limitations and establishes the relative investment and operating costs associated with the technologies, is presented. Twenty-one hydrogen sulfide (H2S) scavengers described in literature as being commercially available were investigated. The study established the relative capital and operating costs and acceptability for treating natural gas, and the results indicated that the scavenging technologies were appropriate for low concentrations of H2S. A relative Screening Index (SI) was developed for comparative evaluations. The SI took into account investment and operating costs, subjective weightings of process reliability, ease of operation, operator acceptance, ease of spent material disposal, and winterization requirements. The SulfaTreat(TM) scavenger was found to have the best rating and lowest total plant investment. The study found that each scavenger had a maximum hydrogen sulfide concentration that it could economically treat, above which it would be more appropriate to use a continuously-regenerative process or an alternative scavenger. Appendixes present technical details of the scavenging systems.
