Industry: Oil Industry
Project Location: Northeast China
Regional characteristics: Northeast China spans the mid-temperate and cold-temperate zones from south to north, belonging to the temperate monsoon climate zone with four distinct seasons. Summers are warm and rainy, while winters are cold and dry. From southeast to northwest, annual precipitation decreases from 1000 mm to below 300 mm, transitioning from humid to semi-humid to semi-arid zones. Northeast China has a high forest coverage rate, which prolongs the snowmelt period, and the snow storage in the forests is beneficial for the development of agriculture and forestry.

Deep-cooled air separation equipment plays an important role in the petroleum industry and is mainly used for the production and separation of industrial gases such as oxygen and nitrogen. As a professional manufacturer of EPC gas equipment, our company provides owners with deep-cooled air separation equipment to produce nitrogen and oxygen.
These gases are crucial in processes such as oil refining, petrochemicals, and natural gas processing.
Oxygen: In petroleum refining, oxygen is often used to increase reaction efficiency, improve combustion, and as an oxidant in certain chemical reactions. In addition, oxygen is used in environmentally friendly processes such as wastewater treatment and tail gas treatment to degrade harmful substances through oxidation.
Nitrogen: Nitrogen is used primarily in the petroleum industry as an inert protective gas to prevent flammable and explosive materials from coming into contact with oxygen in the air. It is used in the purge and replacement of oil and gas storage tanks to ensure production safety. In addition, nitrogen is used in fracturing technology to improve oil well production.
The high efficiency and reliability of Cryogenic air separation equipment provides the petroleum industry with a stable supply of industrial gases, helping it improve production efficiency and safety.
