Abstract

Analyses into the operation of the majority of technological processes in chemical industries have shown that considerable loss of energy occurs during the discharge of surplus heat from these processes into the environment, as well as raw materials and other materials associated with the discharge of useful substances into the environment due to their low utilization in the processes. During recent years the authors have investigated the application of a high temperature heat pump in the industrial waste heat recovery. This paper shows the results of waste heat recovery from the soda-ash production process named "DS-solution". The DS-solution is produced in the quantity of 8-11 m3/t of soda ash, with the temperature between 90-110C. Waste heat recovery from this industrial flow can be achieved in two stages: the exchange of heat in a heat exchanger by cooling the DS-solution from 95C to 68.5C, and then additional waste heat recovery also using adiabatic evaporation of the DS-solution by decreasing the temperature from 68,5°C to 41,4°C by means of a high temperature heat pump which uses heated water from the previous two stages as a low temperature heat source. In this way the heat potential of water is raised to the level which enables its utilization in the system of high temperature district heating of residential buildings and other facilities. Both stages are component parts of the unique process of DS-solution heat recovery as a waste flow produced in the soda ash process.
