在油气勘探领域的钻井过程中,气体检测技术在油气层发现和评价方面发挥着重要作用。目前氢火焰检测技术在油气勘探中占主导地位。随着红外检测技术的逐渐成熟,该技术开始应用于油气勘探。从分析这两种气体检测技术的原理出发,探讨了两种技术各自的优缺点,并对这两种技术在油气勘探领域的应用情况进行了介绍。 相似文献

利用城市垃圾厌氧发酵产沼气是一种非常有前号的能源利用途径,但由于沼气中含有微量的硫化氢气体,对人体和环境将会产生不良作用,故沼气在贮存和利用之前必须经过脱硫处理。本文简要的介绍了目前净化硫化氢气体的一些主要方法。 相似文献

基于在水介质中Cu2+对H2O2氧化甲基橙有催化作用,文章提出一种测定痕量铜的新方法。在此法中Cu2+的浓度在0.02~1.25(μg/25ml)范围内与ΔA呈线性关系,测得反应表观活化能Ea=36.92kJ/mol。此法可用于自来水和试剂中铜的测定。 相似文献

Hydrogen is expected to play a role in the future low-carbon economy as an energy carrier, but its market penetration remains to be seen. Much of the existing literature generally focuses on comparison of marginal production costs and prices to make rather optimistic projections. This study argues that such analysis is myopic as important barriers are ignored. Following Porter’s five-force approach, we methodologically identify the economic market forces that shape the development of hydrogen markets, and discuss key obstacles in the supply chain. Using evidence of available hydrogen technologies and costs, the distribution network is identified as a major fixed-investment barrier to market entry, but it is argued that much of it could be overcome if natural gas infrastructure and technology is shared with the hydrogen sector. Natural gas, in turn, is projected to function as a transition fuel under current carbon emissions targets. This study finds that policy costs needed to promote hydrogen to achieve environmental goals can be substantially reduced if government and private investment decisions strategically focus on synergies with natural gas. The possible formulation of such policies is discussed using Australia’s hydrogen industry as a case study. 相似文献
