页岩油中汞检测方案(测汞仪)

PAGE 1 Application Note APPN-MA-3000-PETRO-002 Total Mercury in Shale OilUsing Direct Mercury Analysis 672 BACKGROUND Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from whichliquid hydrocarbons called shale can be produced. Shale oil is a substitute for conventional crude oil； however， extracting shale oil from oilshale is costlier than production of conventional crude oil， both financially and in terms of its environmental impact. Research has shownthat many shale deposits are high in mercury content and that significant quantities of mercury can be released during oil shale processing.Mercury also poses several issues for downstream refineries beyond just environmental release. Mercury is detrimental to the refiningprocess through amalgamation with other metals， poisoning of catalysts， and liquid metal embrittlement (cracking) with metals such asaluminum. Also， mercury is dangerous to both natural ecosystems and humans because it is highly toxic， especially because of its abilityto damage the central nervous system. Thus， to prevent both mercury poisoning and damage to the refining infrastructure， it is necessaryto accurately quantify total mercury in shale oil.

The MA-3000 offersquick results without any tedious， time-consuming and elaborate sample preparationprocess. It is a perfect solution to today's increasing laboratory demand for easy， fast andaccurate mercury measurements. 背景油页岩是一种富含有机质的细粒沉积岩，含有干酪根(一种有机化合物的固体混合物)，从干酪根中可以生产出被称为页岩的液态碳氢化合物。页岩油是常规原油的替代品;  然而，从油页岩中提取页岩油比生产常规原油成本更高，无论是在财政上还是在环境影响方面。    研究表明，许多页岩沉积物汞含量很高，在油页岩加工过程中会释放大量的汞。汞还对下游炼油厂造成了几个问题，不仅仅是环境污染。汞通过与其他金属混合、催化剂中毒、液态金属与铝等金属脆化(开裂)而对精炼过程有害。此外，汞对自然生态系统和人类都是危险的，因为它是剧毒的，特别是因为它有破坏中枢神经系统的能力。因此，为了防止汞中毒和对炼油基础设施的损害，有必要准确量化页岩油中的总汞含量。NIC公司 MA-3000是一款专用的直接汞分析仪，通过热分解、金汞齐化和冷原子吸收光谱有选择地测量几乎任何样品基质(固体、液体和气体)的总汞。MA-3000提供快速测试的结果，没有任何繁琐、耗时和复杂的样品制备过程。这是一个理想的解决方案，以满足当今实验室对简单，快速和准确的汞测量的需求。
