将原油加工成可用的化石燃料产品

Refineries process crude oil into useable fossil fuel products. The process typically begins by extracting raw crude oil from a well and running it through a distillation tower. As it passes through various levels or trays, the fluid is heated to separate hydrocarbons of dissimilar densities. Lighter hydrocarbon chains will rise to the top of the column while the heaviest will sink to the bottom.

原油是不同烃的异质混合物。一旦分开，它们就可以独立格式化为一系列产品。轻碳氢化合物链（如甲烷，丙烷和丁烷）可以重定向到蒸馏塔，以充当随后分离过程的燃料。它们也通常是出售的。由原子仪器制造的Traces-1000可用于可靠地检查脱硫过程，并确保最终产品中仅存在微量量（0-1000 ppbv）。

蒸馏过程中的废物燃料通常在火炬堆中焚化。高硫水平不能按照美国EPA CFR 60.18 JA子部分。Atom的FGA-1000总硫分析仪可以根据已建立的EPA指定测量总硫，确保安全去除高硫量并重定向到SRU，并可以在炼油厂的其他区域中回收它。

Middleweight hydrocarbon products – like kerosene, gasoline, and naphtha – are directed to fuel blenders where myriad different oil blends can be manufactured to meet the requirements of varied customers. This demands tight control of the fuel blending process. ATOM Instrument’s patented Ultraviolet Fluorescence Systems can assist in Total Sulfur analysis to ensure that all blends and grades are compliant withASTM D5453。一旦确保合规性并正确格式化了混合物，它们就会被送到终端，从世界各地运送它们。

Heavy hydrocarbon chains in the crude must be subjected to sequential distillation processes to break them up into shorter chains. Online analyzers offer real-time data for plant operators to inform decision-making processes on how to achieve the optimal yield from residue products.
