Abstract
Ammonia can be stored and recovered by a process which includes the steps of: (a) absorbing ammonia into an alcohol to form an alcohol/ammonia solution; (b) holding the alcohol/ammonia solution in a reservoir for subsequent recovery of ammonia therefrom: and (c) heating and/or reducing the pressure of the alcohol/ammonia solution to liberate ammonia therefrom.
Claims12
A process for storing ammonia, the process including the steps of:
- (a) absorbing ammonia into an alcohol to form an alcohol/ammonia solution;
- and
- (b) holding the alcohol/ammonia solution in a reservoir for subsequent recovery of ammonia therefrom.
A process as claimed in any one of the preceding claims wherein the alcohol/ammonia solution is held in the reservoir at ambient pressure.
A process as claimed in any one of the preceding claims wherein the ammonia is absorbed into the alcohol in the reservoir.
A process for recovering ammonia from an alcohol/ammonia solution, the process including the step of heating and/or reducing the pressure of the alcohol/ammonia solution to liberate ammonia therefrom.
