Abstract: In a process for separating carbon dioxide from a waste gas (3) of a fluid bed catalytic cracking installation (1) containing carbon dioxide, nitrogen and possibly carbon monoxide, the waste gas (3) is separated by adsorption to form a gas enriched in carbon dioxide and depleted in nitrogen (29) and a gas rich in nitrogen and depleted in carbon dioxide (31), and at least a portion of the gas enriched in carbon dioxide and depleted in nitrogen is separated in a separation device (30) by way of separation at a temperature of less than 0° C. by partial condensation and/or by distillation to form a fluid rich in carbon dioxide (35) and a fluid depleted in carbon dioxide (37).

Abstract: Disclosed are Germanium- and Zirconium-containing precursors having one of the following formulae: wherein each R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 is independently selected from H; a C1-C5 linear, branched, or cyclic alkyl group; and a C1-C5 linear, branched, or cyclic fluoroalkyl groups. Also disclosed are methods of synthesizing the disclosed precursors and using the same to deposit Zirconium-containing films on substrates via vapor deposition processes.

Abstract: The invention relates to a method for producing an NO/N2 gaseous mixture, comprising the steps of effecting a purification of impure gaseous nitrogen containing impurities at least of the O2 type by putting the impure nitrogen in contact with a catalyst and then with a molecular sieve; mixing the pure nitrogen obtained with nitric oxide (NO), and obtaining a mixture formed from NO and pure nitrogen containing an NO content of less than 20% by volume and a proportion of impurities of the O2 type of less than 5 ppmv and of the H2O type of less than 40 ppmv. The NO/nitrogen mixture may undergo supplementary dilutions with pure nitrogen. Such NO/nitrogen mixtures can be used for treating, by inhalation, pulmonary vasoconstrictions in adults or children, in particular in new-born babies suffering from primitive pulmonary hypertension or in patients undergoing heart surgery.

Abstract: A process for separating carbon dioxide from a carbon dioxide containing fluid comprises the steps of: compressing the fluid in a compressor to form a compressed fluid, drying at least part of the compressed fluid to form a compressed and dried fluid, cooling at least part of the compressed and dried fluid to form a compressed, dried and cooled fluid, separating the compressed, dried and cooled fluid at a temperature lower than 0° C. into a carbon dioxide rich stream, a carbon dioxide lean stream and at least one intermediate purity liquid stream having a carbon dioxide purity lower than that of the carbon dioxide rich stream and higher than that of the carbon dioxide lean stream, expanding at least one intermediate purity liquid stream to produce at least one expanded stream using at least one expanded stream to cool the compressed and dried fluid and recycling at least part of the expanded stream.
