520			_aThe corrosive effects of hydrogen sulfide result in significant additional operating costs for production, including higher pipeline failure rates as well as souring of the produced oil and gas. In order to mitigate the effects of hydrogen sulfide and produce in spec oil and gas, chemical scavengers are often applied, typically topside and post-separation. However, application of the appropriate chemistry requires knowledge of the impact of system parameters, such as temperature and pH, on the performance of the scavenging chemical. In this regard, a novel product has been developed that exhibits good hydrogen sulfide scavenging performance in aqueous conditions over a wide temperature and pH range. The kinetics and mechanism of H2S scavenging are discussed and compared with current technologies employed for hydrogen sulfide scavenging, such as triazines. In addition, we report case histories of this new, non-scaling chemical scavenger that exhibits excellent hydrogen sulfide scavenging performance for downhole applications. Further, we show how detailed knowledge of the system parameters and the kinetics and mechanism of H2S scavenging provide a means for predicative performance and optimization within individual systems
