摘要： The concerns a process for producing formic acid, (a) a carbon capture step in which a source of carbon dioxide is contacted with an amine solution in an amine scrubber, to obtain an ammonium bicarbonate solution, where the carbon capture uses a chilled amine solution having a temperature in the range of 0-20 ° C.; (b) inducing crystallization in the ammonium bicarbonate solution to obtain a concentrated ammonium bicarbonate solution; (c) subjecting the concentrated ammonium bicarbonate solution to a hydrogenation step to obtain an ammonium formate; and (d) heating the ammonium formate to a temperature in the range of 50-150 ° C., to obtain a gaseous product containing the amine and a liquid product stream containing formic acid. The application further concerns a system for performing the process.
