A method for reducing the mercury content of natural gas condensate, comprising the steps of providing a nanofiltration membrane having a feed side and a permeate side; contacting the natural gas condensate with the feed side of the membrane; and obtaining a mercury-depleted natural gas condensate at the permeate side of the membrane; and a natural gas processing plant comprising a condensate workup section including a nanofiltration membrane separation unit for reducing the mercury content of natural gas condensate.

The invention relates to a process for the production of hydrogen and carbon dioxide from a hydrocarbonaceous feedstock, comprising: a) supplying a gaseous hydrocarbonaceous feedstock and steam to a reaction zone comprising a steam reforming catalyst and catalytically reforming the hydrocarbonaceous feedstock to produce a reformed gas comprising hydrogen and carbon dioxide; b) supplying a molecular oxygen-comprising gas to the permeate side of a first hydrogen separation membrane; c) contacting a part of the hydrogen with a first hydrogen separation membrane, allowing the hydrogen to permeate through the first hydrogen separation membrane and combusting the hydrogen with the molecular oxygen at a permeate side of the first hydrogen separation membrane to produce all heat necessary for catalytic reforming the hydrocarbonaceous feedstock; d) contacting the remainder of the hydrogen with a second hydrogen separation membrane, which is separate from the first hydrogen separation membrane, and allowing the hydrogen to permeate through the second hydrogen separation membrane to obtain a first effluent comprising a substantially pure stream of hydrogen; and e) removing a stream rich in carbon dioxide from the reaction zone as a second effluent. The invention further related to a reactor for such process and to a fuel cell system comprising in series such reactor and a fuel cell.

The invention concerns a process for the removal of gaseous acidic contaminants, especially carbon dioxide and/or hydrogen sulphide, in two or more stages from a gaseous hydrocarbonaceous feedstream () comprising hydrocarbons and said acidic contaminants, using one or more membranes in each separation stages. The gaseous hydrocarbonaceous feedstream is especially a natural gas stream. The process is especially suitable for feedstreams comprising very high amounts of acidic contaminants, especially carbon dioxide, e.g. more than 25 vol. %, or even more than 45 vol. %. In a first stage () a pure or almost pure stream of acidic contaminants is separated from the feedstream, the acidic contaminants () stream suitably containing less than 5 vol % of hydrocarbons. The remaining stream () comprises the hydrocarbons and still a certain amount of gaseous acidic contaminants. In a second stage () a pure or almost pure stream of hydrocarbons () is separated from the remaining stream, where after the then remaining stream () is combined with the feed for the first stage (), the hydrocarbon stream suitably containing less than 5 vol % of acidic contaminants.

Multi-stage membrane separation process

A process for the extraction of hydrogen from a gas mixture including hydrogen and carbon monoxide and optionally nitrogen, carbon dioxide, lower hydrocarbons and/or water, by contacting the gas mixture with a non-porous polyimide-based membrane, especially with the selective side of an asymmetric membrane, to obtain a hydrogen rich permeate and a hydrogen lean retenate, the polyimide-based membrane being a specific mixture of two polyimids. This specific membrane shows a very high hydrogen/carbon monoxide selectivity. The process is especially suitable for the upgrading of synthesis gas obtained by partial oxidation and/or reforming of hydrocarbonaceous feedstream for use in hydrocarbon synthesis reaction as the Fischer-Tropsch reaction.
