20160115408 | APPARATUS FOR SWEETENING AND/OR DEHYDRATING A HYDROCARBON GAS, IN PARTICULAR A NATURAL GAS - An apparatus for actuating method for removing acidity and/or moisture from a hydrocarbon gas, by absorption into a sweetening liquid and into a dehydration liquid, that are adapted to extract acid compounds or water from the gas, respectively. The apparatus includes at least such a container and a gas convey selective convey means, for actuating the treatment modes, in particular responsive to a flowrate of the gas. The apparatus according to the invention allows to maintain the sweetening and/or dehydration efficiency, in particular in the case of a progressive reduction of the flowrate of natural gas that can be obtained from a well or gasfield. | 04-28-2016 |
20140353216 | SEPARATION OF HYDROCARBON FAMILIES OR OF INDIVIDUAL COMPONENTS BY CONSECUTIVE EXTRACTIVE DISTILLATIONS PERFORMED IN A SINGLE COLUMN - A column for consecutive extractive distillations, in particular of crude hydrocarbon mixes comprising aromatic, naphthene and paraffin hydrocarbons. The invention also relates to methods for separating and recovering the components of a crude hydrocarbon mix comprising aromatic, naphthene and paraffin hydrocarbons by consecutive extractive distillations provided by means of the column for consecutive extractive distillations, to which the invention also relates. | 12-04-2014 |
20130035534 | METHOD AND AN APPARATUS FOR NGL/GPL RECOVERY FROM A HYDROCARBON GAS, IN PARTICULAR FROM NATURAL GAS - A method for separating methane from at least one hydrocarbon with two or more carbon atoms in a substantially gaseous fluid, containing more than 3 ppm of water, in particular a natural gas coming from a natural gas field or from a natural gas pipeline, or a refinery gas or another gas available at an extraction pressure set between 15 and 300 bar, and an apparatus. The method provides prearranging an expansion device having at least one first expansion equipment, selected from the group comprised of: a radial expansion device and a static expansion device, in which a first expansion takes place with a cooling effect down to a temperature that is higher than the solid formation temperature that may be formed starting from water and/or hydrocarbons present in said gas, and further having at least one second expansion equipment which is arranged downstream of the first expansion equipment. | 02-07-2013 |
20130019612 | METHOD AND APPARATUS FOR RECOVERING FROM A PRESSURIZED GAS A LIQUID FRACTION, IN PARTICULAR HYDROCARBONS HAVING TWO OR MORE CARBON ATOMS - An expansion device having a passageway formed orderly by a tubular inlet portion, a tubular throat portion and a tubular outlet portion, with a closing element arranged in the throat portion, the closing element adapted to cause a Joule-Thomson expansion and cooling of an at least partially gaseous fluid that is supplied at a predetermined pressure (P | 01-24-2013 |
20130019530 | METHOD AND AN APPARATUS FOR SWEETENING AND DEHYDRATING A HYDROCARBON GAS, IN PARTICULAR A NATURAL GAS - A method and an apparatus for removing acid compounds (sweetening) and moisture (dehydration) from a hydrocarbon gas, in particular from a natural gas or from a refinery gas fraction or a gas of synthesis, by subsequent absorption operations using a sweetening liquid and a dehydration liquid. The method comprises a step of prearranging a sweetening chamber ( | 01-24-2013 |
