Energy-saving of air separation plant

Energy-saving of air separation plant
The energy consumption of air separation equipment includes all kinds of energy consumption, and the power consumption of operation equipment includes the power consumption of air compressor, water pump, refrigerator and oil pump. The energy-saving technology of air separation plant can reduce the operation power consumption of each equipment, reduce the unit consumption of the total product, and improve the economic benefits of the company. The energy-saving patent adopted by DEAR air separation products can better realize the energy-saving of air separation plant, save the power cost for the enterprise and improve the economic value.

Large air separation plant KDON-16000/35000 solution for metallurgical industry
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. The air separation plant also has the following development trends: first, large-scale and cluster; second, the core technology is gradually localization; third, refinement, which needs to develop high-efficiency energy-saving technology for different application fields; fourth, highly automated and intelligent, reduce manual operation as far as possible, and gradually establish a remote monitoring system by using the rapid development of internet technology to collect in real time according to the operation data of air separation plant, using big data analysis to provide the best suggestions for users, etc. KDON (Ar) - 16000 / 35000, a large scale air separat
4500/4500-type solution for small and medium-sized air separation plant in nonferrous industry
According to the influence and reform of the general environment of the non-ferrous industry, the problems faced by this industry are becoming more and more serious, and the control of production capacity is particularly important. Recently, the 4500/4500 type small air separation equipment project signed with customers by DEAR Air Separation, through the trial run stage, all the technical indicators have reached or exceeded the design standard, and have been continuously sending nitrogen for several days, which has been well received by users.

The skid mounting of equipment refers to connecting the pipelines, equipment, pumps, control cabinets, electrical instruments and other components of the complete set into a whole according to the designed process flow, and fixing them on an integral base through welding, bolting and other connection methods. Without site installation, it can be directly completed the mechanical and electrical integration installation of the whole set in the plant area, then transporting and hoisting will be convenient.

As we know, in order to ensure self-cleaning of all low-voltage air separation plant, the temperature difference of cold end of switching heat exchanger must be controlled within the allowable range of temperature difference to ensure self-cleaning. The self-clearing temperature difference of the cold end is the temperature difference between the positive air passing through the section of the cold end and the return air passing through this section. In normal operation, the measured temperature difference at the cold end is self-cleaning temperature difference. However, in the start-up stage of the air separation unit, the temperature of the switching heat exchanger decreases continuously with time, and the self-clearing temperature difference of the temperature of the positive return flow through the channel is far greater than the measured temperature difference of the cold end. In addition, with the extension of switching time and the acceleration of temperature drop, the temper...
