Abstract: A capture system for offshore carbon dioxide capture and a method for offshore carbon dioxide capture are described. A capture system for offshore carbon dioxide capture, the system comprising: a pressurised flue gas source configured to provide a pressurised flue gas 101; a solvent source configured to provide a liquid solvent; and a two-phase atomising nozzle in fluid communication with the pressurised flue gas source and the solvent source; wherein the two-phase atomising nozzle is configured for two-phase flow of a mixture of the pressurised flue gas and the liquid solvent in order to generate an atomised solvent spray of the liquid solvent.

Abstract: The present invention relates to an absorbent, an absorbent system and a process for removing acidic gas such as CO2 from exhaust gases from fossil fuel fired power stations, from natural gas streams, from blast furnace oven off-gases in iron/steel plants, from cement plant exhaust gas and from reformer gases containing CO2 in mixtures with H2S and COS. The liquid absorbent, a mixture of amine and amino acid salt is contacted with a CO2 containing gas in an absorber and CO2 in the gas stream is absorbed into the liquid. The absorbed CO2 forms more than one type of solid precipitate in the liquid at different absorption stages. In a first absorption stage solid precipitate of amine bicarbonate is formed and is withdrawn as slurry from the bottom of a first absorber section. In a second absorption stage solid precipitate of alkali metal bicarbonate is formed and withdrawn as slurry at the bottom of a second absorber section.

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.

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.
