Abstract: The invention relates to a gas/liquid separation column extending mainly along a vertical axis and comprising an external wall delimiting an internal space in which are arranged at least one first contact member in which the liquid and the gas are brought into contact and at least one dispensing device configured to collect the liquid resulting from the first contact member and to distribute it to a second contact member. At least one box for separating a two-phase fluid is arranged in the internal space of the column between the first contact member and the dispensing device against the wall of the column fed by a duct which passes through a wall of the separation box.

Abstract: A process for compressing a gaseous fluid comprising a step (a) of injecting refrigerant during which a refrigerant substance is sprayed into the gaseous fluid to be compressed, and also a compression step (b), during which the passage of said gaseous fluid loaded with refrigerant substance is forced through said compressor in order to compress said gaseous fluid, the mass flow rate (Q3) of the refrigerant substance injected into the gaseous fluid represents between 1% and 5% of the mass flow rate of the gaseous fluid to be compressed, and the refrigerant substance is sprayed in the form of particles having a maximum dimension of less than or equal to 25 pm, and preferably less than or equal to 10 pm.

Abstract: The invention relates to a method for cooling, purifying and separating a gaseous mixture containing at least one impurity, in which the gaseous mixture is cooled to a temperature no higher than the temperature at which the at least one impurity solidifies in a heat exchanger having cooling passages, the cooling passages being at least partially covered with a coating and/or physically treated and/or chemically treated, the coating and/or the treatment serving to limit or even prevent the solidified impurity from forming and/or adhering to a surface of the passages; at least one portion of the solidified impurity exiting the cooling passages of the heat exchanger is collected; and the gaseous mixture is withdrawn from the heat exchanger.

Abstract: In a method for separating air by separation at sub-ambient temperature, a first heat pump, using the magnetocaloric effect, exchanges heat between a cold source at sub-ambient temperature and a hot source at sub-ambient temperature, thus providing at least some of the separation energy, and a second heat pump, using the magnetocaloric effect, exchanges heat between a cold source at sub-ambient temperature and a hot source at ambient temperature thus providing at least some of the cold needed to maintain the refrigeration balance of the method, the separation taking place in a single column at a pressure of below 2 bara.

Abstract: In a method for separating a gaseous mixture by separation at sub-ambient temperature, a gaseous mixture at a first pressure is cooled, then separated in a separation unit, a liquid is withdrawn from the separation unit and vaporized to form a pressurized gaseous product, and at least part of the heat of vaporization of the liquid is supplied by a heat pump using the magnetocaloric effect, of which the hot source exchanges heat, directly or indirectly, with the liquid which vaporizes.

Abstract: In a method for separation at sub-ambient temperature, a mixture of fluid at sub-ambient temperature is sent to a system of separation columns comprising at least one separation column, a fluid enriched in a lighter component of the mixture leaves the top of one column of the system and a fluid enriched in a heavier component is withdrawn from the bottom of one column of the system, the cold source of a heat pump using the magnetocaloric effect is thermally connected to a first zone of one column of the system and the hot source of the same heat pump is thermally connected to a second zone of the same or of another column of the system.

Abstract: Disclosed are methods for forming a metal-containing layer on a substrate. The methods include providing a vapor and at least one reaction gas and reacting the vapor and the reaction gas with the substrate by a deposition process. The vapor may be selected from the group consisting of (Cp)V(?NtBu)(NEt2)2; (Cp)V(?NtBu)(NMe2)2; (Cp)V(?NtBu)(NEtMe)2; (Cp)V(?NiPr)(NEt2)2; (Cp)V(?NiPr)(NMe2)2; (Cp)V(?NiPr)(NEtMe)2; (Cp)V(?NC5H11)(NEt2)2; (Cp)V(?NC5H11)(NMe2)2; (Cp)V(?NC5H11)(NEtMe)2; (Cp)Nb(?NtBu)(NEt2)2; (Cp)Nb(?NtBu)(NMe2)2; (Cp)Nb(?NtBu)(NEtMe)2; (Cp)Nb(?NiPr)(NEt2)2; (Cp)Nb(?NiPr)(NMe2)2; (Cp)Nb(?NiPr)(NEtMe)2; (Cp)Nb(?NC5H11)(NEt2)2; (Cp)Nb(?NC5H11)(NMe2)2; and (Cp)Nb(?NC5H11)(NEtMe)2.
