<p>Potassium or other alkali metal formate solution (30) is used to absorb moisture from gas (21) through a membrane (22). The membrane (22) may be supported on permeable tubes, and the potassium or other alkali metal formate (32) may be regenerated for reuse, preferably by a cavitation regenerator (29). The potassium or other alkali metal formate should be present as a 40-80 % solution, most preferably 70-76 %. The process is especially useful for the dehydration of natural gas.</p> |
