ABSTRACT:
An absorbent solution for absorbing and desorbing useful quantities of ammonia vapor is disclosed. The absorbent has much lower vapor pressure than water, and has a wider solubility field and higher crystallization limit than any previously known non-volatile absorbent for ammonia. It is useful in absorption cycle processes and apparatus requiring high lifts from temperatures well below freezing, e.g., in thermally actuated industrial refrigeration systems or cold-climate absorption heat pumps for space heating. The new absorbent is also useful with other ammonia-type vapor, e.g., monomethylamine.
