Thermal energy recovery and storage by a sulphuric acid-water process

The processes of liquid-liquid absorption can contribute to the solution of problems in conservation and storage of energy. The sulphuric acid-water process has been proposed as one of the best processes to be used in a chemical heat pump and heat transformer system. In the present paper the principal applications of the process are described, several schemes are suggested and discussed, pointing out the technical and economical problems for each application. Experimental results, together with the state of the art of research in this field, are reported. © 1987.
