"Application and benefit evaluation of cold energy utilization technology for low-temperature emulsion styrene-butadiene rubber "

In order to solve the problem of high- temperature in the common engineering desalted water during the summer production process of low-temperature styrene-butadiene rubber plant, four heat exchangers were added to the original equipment for improvement. Through the counter current heat transfer method of cold latex passing through the tube side and desalted water passing through the shell side, the low-temperature latex after the polymerization reaction was heat exchanged with desalted water, so as to achieve the purpose of reducing the desalted water temperature. The economic benefits of implementing the technical scheme were evaluated. The results showed that the cold energy utilization technology could effectively reduce the energy consumption of the refrigeration compressor, the amount of circulating water and the consumption of additives, and achieve the purpose of stable control of the reaction.
