After the air separation equipment has been purged, the welding slag, aluminium chips, dust and impurities remaining in the pipes and vessels are purged out to ensure the cleanliness of the interior of the equipment.
The application of air separation equipment in the non-ferrous industry has laid a solid foundation for the non-ferrous industry. With the rapid development of the industry and the production needs of the enterprises, the small air separation plant 3000/300Y project cooperated with customers by DEAR Air Separation has won unanimous praise from customers.
The main applications of the air separation plant in petroleum industry include the use of natural gas or heavy oil to produce synthetic ammonia, olefin and petrochemical products, as well as providing nitrogen for oil extraction. The implementation of 1500 small air separation plant project cooperated with clients by DEAR air separation plant is beneficial to the improvement of crude oil processing scale in Shengli oilfiel
Oxygen generators are switchable heat exchanger process oxygen generators and molecular sieve pressurised expansion process oxygen generators.
The pure liquid nitrogen supplied to the upper tower is less and a stream of dirty liquid nitrogen can be pumped to the upper tower.
The oxygen generator of the pressurised expansion process, b...
The process of stripping is a process of continuous exchange between the high boiling point components in the rising gas and the low boiling point components in the reflux liquid. As a result, the high boiling point components in the rising gas are continuously reduced until the top of the stripping section reaches the gas phase composition of the distillation raw material. Meanwhile, the low boiling point components in the reflux liquid are continuou...
