产品介绍

Hydrogenation unit is a core high-temperature, high-pressure hydrogen-bearing reaction equipment in refineries, mainly used for oil product cleaning, quality upgrading and heavy oil lightening.

A Hydrogenation Unit purifies petroleum products by removing sulfur and nitrogen under high pressure with hydrogen.

It improves fuel quality, reduces emissions, and produces cleaner gasoline, diesel and jet fuel.

It uses hydrogenation reactions to stabilize oil fractions and meet strict environmental specifications.

Hydrogenation Unit

A Hydrogenation Unit removes sulfur and impurities from petroleum fractions to produce cleaner fuels.

Hydrogenation Unit

It uses hydrogen under high pressure to improve fuel stability and meet environmental standards.

Basic Principles and System Composition

Basic Working Principle

The feedstock react with hydrogen to form H₂S and NH₃ which are then removed. Olefins and aromatics are saturated, improving the stability and color of oil products, thus achieving refining and upgrading of oil products.

Overall System Composition

System Composition

Feed System: Feed buffer tank, feed pump, hydrogen-mixing heat exchanger Reaction System: Hydrogenation reactor, heating furnace, high-temperature and high-pressure heat exchanger Hydrogen Circulation System: Recycle hydrogen compressor, make-up hydrogen compressor, separator drum High-Pressure Separation System: High-pressure separator, low-pressure separator, air cooler Stripping and Fractionation System: Stripping tower, product fractionation tower, reflux system Tail Gas Treatment System: Amine solution desulfurization, acid gas recovery Control System: DCS distributed control system, SIS safety instrumented system

Basic Principles and System Composition

Process Flow

The feed oil is mixed with recycle hydrogen, heated through heat exchange, and fed into the heating furnace.It then enters the hydrogenation reactor, where hydrotreating reactions are completed under the action of a catalyst.The reaction products are cooled and sent to a high-pressure separator, where hydrogen is recycled.The liquid phase enters a low-pressure separator to remove dissolved gas.The material is fed into a stripping tower to remove light components such as H₂S and NH₃.Refined gasoline, diesel oil or kerosene is obtained at the bottom of the tower and sent out of the unit.
