设计用于 将原煤油馏分升级为煤油或喷气燃料 (A和A-1），Elessent清洁技术公司采用了经过商业验证的但 创新的 IsoTherming® technology to enable refiners to meet the specification requirements. The IsoTherming® kerosene hydrotreating units have been commercially operating since 2006, making < 10ppm sulfur products. Unique to the IsoTherming® process is a liquid full reactor 确保催化剂完全润湿，消除分布不均现象，从而最大限度地提高煤油产量。
Kerosene feed types typically have low hydrogen consumption and often do not require an external recycle stream to satisfy hydrogen availability requirements as illustrated below. The IsoTherming® technology provides the ability to supply the necessary hydrogen solely through feed saturation without requiring a recycle pump which results in even fewer pieces of high pressure equipment. 与传统技术相比，资本成本大大降低，使炼油厂受益匪浅.
当炼油厂在煤油加硫和加氢处理之间做出选择时，往往会进退两难。通常情况下，他们选择高度不灵活的加硫装置纯粹是因为资本或运营成本较低。然而，如果他们选择了加硫，炼油厂就失去了生产优质、高价值航空燃料和混合超低硫柴油组分的灵活性（十六烷值、低温流动特性等）。
With IsoTherming® hydrotreating units, refineries gain several advantages:
与传统的涓流床配置相比，上述几点可带来可观的资本成本（高达 30%）和运营成本效益（30-60%）。
This makes IsoTherming® kerosene hydrotreating an attractive alternative for refineries when compared to inflexible sweetening units.
