Abstract
Liquid ammonia at a temperature of approximately -28.degree. F has its temperature raised to a level more suitable for transporting it, e.g. 40.degree. F, by passing it in heat exchange relation with higher temperature ammonia vapor which results from passing a liquid, such as water, from a waste heat source, in heat exchange relation with the ammonia, the vapor then condensing and the condensate returning to the heat exchange relation with the water, controls being provided to avoid inadvertent freezing of the water.
