酸性气体回注、硫磺的储存及硫能源

论述酸性气体回注、硫磺的储存以及硫磺在能量生产中的应用。对北美,尤其是加拿大西部正在进行的酸性气体回注项目进行分析,结果表明,将H2S回注入耗竭的矿井已达到相当的规模,并开始影响该地区的硫磺供应。在世界其它地区,只要能够找到合适的矿井,实施更大规模的回注计划似乎已不存在技术障碍。只要在项目的生命周期内进行适当地规划和维护,传统的地面硫块储存是一项可行而安全的技术。硫磺的地下储存仍然是现场中试研究的一个焦点,对于长期储存可能是一项非常有用的技术。提出了一些利用H2S和硫磺生产能量的方案,将H2S通过“绿色”技术进行燃烧和可再生循环。其中两种方案利用了太阳能,一种是间接通过生物质的积累,另一种则是直接使用太阳能收集器。

Acid gas injection, storage of sulphur and sulphur as an energy source

Acid gas injection, sulphur storage and use of sulphur in energy production are discussed. Analysis of acid gas injection projects underway in North America, and in Western Canada in particular, show that disposal of H2S into depleted reservoirs may have already reached levels that begin to affect sulphur supply from that region. There seems to be no technical impediment for introduction of much larger injection schemes elsewhere in the world given that a disposal reservoir is available. Storage of sulphur in conventional surface blocks is a viable and safe technology as long as adequate planning and maintenance are applied throughout the lifetime of the project. Underground storage of sulphur continues to be a focus of field pilot-scale studies and may be a very useful technology for long-term sulphur storage. Schemes for utilization of H2S and sulphur for energy production involving combustion and regenerative re-cycle of H2S via " green" technology are presented. Two of these schemes harness solar energy, one indirectly through bio-mass accumulation and other directly via a solar energy collector.
