Abstract
The present invention provides a liquid handling system comprising a reactor, wherein the reactor is structured such that it contains a gaseous phase and an aqueous phase, both phases being in contact with a heterogeneous hydrogenation catalyst immobilised or suspended within the aqueous phase, wherein the gaseous phase comprises hydrogen and wherein the aqueous phase comprises (i) a solution of amines; and (ii) nitrosamine and/or nitramine compounds resulting from amine-based gas sweetening processes. The invention further relates to a process for in-situ destruction of compounds in the aqueous phase from a scrubber system, wherein the process comprises contacting the aqueous phase with a gas phase comprising hydrogen and a heterogeneous catalyst, wherein the aqueous phase comprises (i) a solution of amines; and (ii) nitrosamine and/or nitramine compounds resulting from amine-based gas sweetening.
