Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.
Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. [1] The term usually refers to the removal of sulfur from a molecule or a material by hydrogenolysis: [2] R 2 S + 2 H 2 → 2RH + H 2 S. Hydrogen is the ultimate sulfur acceptor. As applied to oil refinery streams, the conversion is known as ...
The air pressure system on a tire changer provides the air to inflate tires mounted on wheels. The air pressure system consists of 4 components: air hose, air inflation gauge, inflation pedal and manual pressure bleed valve. The air hose is located near the top of the tire changer, and it allows compressed air to travel into the tire.
Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel, red diesel and biodiesel. This fuel contamination, also known as 'fuel bugs', or 'diesel bugs', or 'so ...
An alternative to removing sulfur from the flue gases after burning is to remove the sulfur from the fuel before or during combustion. Hydrodesulfurization of fuel has been used for treating fuel oils before use. Fluidized bed combustion adds lime to the fuel during combustion. The lime reacts with the SO 2 to form sulfates which become part of ...
In oil refineries, that stripped gas is mostly H 2 S, much of which often comes from a sulfur-removing process called hydrodesulfurization. This H 2 S-rich stripped gas stream is then usually routed into a Claus process to convert it into elemental sulfur. In fact, the vast majority of the 64,000,000 metric tons of sulfur produced worldwide in ...
