n: A kind of active agent, which is made by sulphonating tall oil with fuming sulfuric acid.

n: The drug that can introduce sulfonic acid to some chemical compound in particular condition

n: The process that introducing sulfonic acid to some chemical compound by sulfonating agent in particular condition .

n: (S) a pale yellow, nonmetallic chemical element. In its elemental state- free sulfur-it has a crystalline or amorphous form. In many gas streams, sulfur may be found as volatile sulfur compounds- hydrogen sulfide, sulfur oxides, mercaptans, carbonyl sulfide. Reduction of their concentration levels is necessary for corrosion control and, in many cases, necessary for health and safety reasons.

n: a colorless gaseous compound of sulfur and oxygen (SO2) with the odor of rotten eggs. A product of the combustion of hydrogen sulfide, it is poisonous and irritating.

n: light crude oil that contains sulfur compounds, often in the form of hydrogen sulfide. a capacity larger than 100,000 deadweight tons but less than 500,000 deadweight tons (45,360 deadweight tonnes) are called very large crude carriers. Those with a capacity over 500,000 deadweight tons are called ultralarge crude carriers.

n: a plant that makes sulfur from the hydrogen sulfide extracted from natural gas. One-third of the hydrogen sulfide is burned to sulfur dioxide, which reacts with the remaining hydrogen sulfide in the presence of a catalyst to make sulfur and water.

n: a colorless, oily liquid compound of hydrogen, sulfur, and oxygen (H2SO4) strongly poisonous and corrosive. It is formed when hydrogen sulfide (H2S) or sulfur dioxide (SO2) is mixed with water (H2O). Also called vitriolic acid.

n: a colorless liquid compound of hydrogen, sulfur, and oxygen (H2S03) weakly corrosive, with the odor of sulfur. It is formed when hydrogen sulfide (H2S) or sulfur dioxide SO2 is mixed with water (H2O).

n: the depression that occurs in the summer months in the daily load of a gas-distribution system or pipeline.
