1·“Sweetening” is the removal of CO2, hydrogen sulfide and other contaminants from contaminated gas, (often called sour gas due to the sulphur smell), and is a $12 billion-year-business in the US alone.
“脱硫”是从被污染的气体中清除二氧化碳、硫化氢和其它污染物质，（由于污染气体有硫的味道往往被称为酸气），这项工作仅在美国就是一年一百二十亿的生意。
2·The experimental results show that the adsorbent can remove the mercaptan and other sulfide from gasoline, and provide the basis for developing the gasoline sweetening technology.
结果表明该吸附剂具有净化汽油中硫醇和总硫的双重效果，为汽油脱硫技术开发提供一定的基础。
3·A new type of fixed bed LPG mercaptan oxidation catalyst and activated carbon sweetening agent have been developed in laboratory.
在实验室研制出新的固定床液化石油气硫醇氧化催化剂和活性炭脱硫剂。
4·Various natural gas sweetening processes were developed and grasped at home, and have met the gas field developing need on the whole at present.
国内已开发掌握了多种天然气脱硫工艺，基本上满足了当前气田开发的需要。
5·Natural gas : drying, sweetening, acid gas treatment.
天然气：干燥，脱硫，酸气处理。
