Modeling the Operation of a Cooling System for Return Ethylene in the Production of High-Pressure Polyethylene

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The authors have presented a mathematical description of the process of cooling of ethylene in countercurrent heat exchangers of the ″double-pipe″ type, where the ethylene gas is flowing in the inner tube, and water is moving countercurrently in the intertubular space. Such a system belongs to the basic cycle of polymerization of ethylene by the high-pressure method. Basic properties of heat-exchange apparatuses of a cooling system and its parameters have been described. The interrelation between such physical quantities as pressure, temperature, flow rates of coolants, and heat-transfer surfaces of circulating water and return ethylene has been determined. The proposed model takes account of the ″sticking″ of a liquid polymer onto interior tube walls.
