Centralised drainage design for the whole machine
①For small air separation units and downhole equipment, a fixed and uniform centralised drainage outlet is designed on the skid block.
②For large air separation units, the centralised drainage components are prefabricated in the workshop according to the design and taken away with the delivery, and then incorporated into the drainage line during installation on site according to the actual situation on the customer's side.

Design of the operating instructions for the liquid air separation plants
Change the current operation manual content is cumbersome. The status quo of operation is not strong, and the contents of the manual are streamlined and enriched to enhance its practicality.

Standardised design of electrical processes
Standardised design of electrical processes, including standardisation of electrical control schemes. Standardisation of the assembly process. Standardisation of external wiring, standardisation of electrical wiring process drawings and standardisation of program design, comprehensive standardisation of electrical design and wiring work, and improvement of the industrial level of electrical application of equipment.
① Standardisation of control schemes Preparation of "Technical documentation on standardised control schemes for small air separation units, large air separation units and liquid air separation plants" with detailed tables.

DEAR has led the development of many innovative technologies, such as the new main condensing evaporator, self-cleaning filter, energy-saving oxygen generator, energy-saving air separation nitrogen water pre-cooling system, ultra-low-pressure air separation unit, double-stage fractionation tower with liquid lift function for low-pressure air separation equipment.

Regulation of liquid nitrogen throttle valve

Regulation of liquid nitrogen throttle valveThe opening of the liquid nitrogen throttle valve not only affects the reflux ratio of the upper tower, but also affects the reflux ratio of the lower tower. When the opening is increased, the reflux ratio of the upper tower increases, while the reflux ratio of the lower tower decreases, the purity of the nitrogen in the upper tower increases, and the purity of the oxygen enriched night sky in the lower tower increases. However, after the opening is over, the purity of the liquid nitrogen decreases, and the reduction of the reflux ratio of the upper tower is also detrimental to the improvement of the purity of the liquid oxygen. Therefore, an equilibrium point should be found for the opening of the liquid nitrogen throttle valve. We can generally use the purity difference between liquid nitrogen and gas nitrogen to judge whether the opening is appropriate. Generally, the purity of the sprayed liquid nitrogen is equal to that of the upper towe

What is the entropy in the air separation unit?

In the field of air separation, entropy is the core thermodynamic parameter to measure the energy quality and irreversibility of the system, which directly determines the energy consumption level and operation efficiency of the unit. Entropy, with the symbol s, is essentially a measure of the degree of chaos and energy unavailability of a system, in kj/(kg ・ K). The second law of thermodynamics clearly states that the total entropy of an isolated system only increases but does not decrease, that is, the principle of entropy increase. The higher the entropy, the lower the energy quality, and the more difficult it is to convert into cold energy or useful work; The smaller the entropy, the more orderly the energy, and the more sufficient the available energy. The essence of air separation unit is the combination of cryogenic refrigeration and distillation separation, and the whole process is closely related to entropy. The ideal reversible process is an isentropic process, and the entropy
