NEW ABSORPTION-CYCLE PROCESS FOR UPGRADING WASTE HEAT.

In a great many industrial sectors and particularly in the petroleum industry, energy is consumed in the form of heat and then discharged, mostly at a lower temperature. In such cases, discharged heat can be recovered and upgraded by means of devices operating on thrithermal cycle. Such cycles may be mechanical, but absorption cycles may also be used without any compression and expansion machinery. Recent advances in this field indicate that considerable development of such techniques can be expected.
