In China, freeze-drying devices are gradually being used for compressed air drying after the 1990s. The freeze-drying device has mature technology, reliable operation and convenient management. A disadvantage of the freeze-drying device is that it is difficult to obtain a compressed air with a low dew point. The lowest dew point of the compressed air obtained by the conventional freeze-drying device is 13e, and the relative power consumption is also small. The heat-free regenerative composite drying device has mature technology and convenient management, and can obtain low-depression high-quality compressed air, and the compressed air dew point can be up to -70e, and the power consumption in the drying process is relatively low. Introduction to the equipment There are four kinds of condensate in the boundary area of ​​Qilu Petrochemical Second Fertilizer Plant: butanol condensate, turbine condensate, medium pressure condensate and low pressure condensate. The low-pressure condensate is the heat-contaminated and hydrophobic of the condensate and residue oil and the process tail gas generated by each steam pipe network during the steam transfer process. The medium-pressure condensate is the condensation generated by the Heat Exchanger medium after heat exchange with the steam. Liquid, such as residue preheater, air preheater, etc.; turbine condensate is mainly the condensate produced by steam through the air compressor turbine, generator turbine, oxygen compressor turbine work; butanol condensation The liquid is the condensate produced by the heat exchange of the heat exchanger in the boundary zone of the butanol plant. The necessity of condensate recovery B801 is the key supporting device for the entire new district of Qilu Petrochemical Second Fertilizer Plant. As it is an oil-fired boiler, in the face of rising international crude oil prices, measures must be taken to improve boiler efficiency to reduce residual oil consumption. . It is one of the main measures to fully recycle the waste heat of various condensates and save refined water and steam. In addition, when designing a compressed air station, sometimes the calculated consumption of compressed air is just right for the series of air compressors. If the heat regeneration gas is increased, it is necessary to increase the number of compressors and the rear processing device. Investment and operating expenses are uneconomical.
