  • Publication number: 20140263096
    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.

  • Publication number: 20130269451
    Abstract: A fluid transfer system or fast-loop is provided for transferring a liquid sample from a liquid source to a remote liquid sample analyser. The system comprises a capillary that connects the liquid source and the liquid analyser. When the system is used, liquid flows from the liquid source to the liquid analyser via the capillary. The capillary may form a looped circuit between the liquid source and the liquid analyser.

  • Publication number: 20100145115
    Abstract: The present invention relates to a method and system for treatment of a flow of fluid hydrocarbons containing water. The flow of hydrocarbons is introduced into a mixer (7) where it is mixed with liquid carbon dioxide (6) before the resulting mixture is cooled in a cooler (8) and conveyed to a reactor (9), in which all water present in the hydrocarbon flow will be in the form of hydrates, and said flow is conveyed to a pipeline (11) to be transported to its destination. The cooling system may comprise a choke or a mixer where the warm hydrocarbon flow is mixed with a cold flow of hydrocarbons.
