Abstract: A method of capturing acid compounds contained in a gas, wherein the following stages are carried out: a) contacting (R1) gas (2) with a liquid solution (9) comprising a mixture of an aqueous phase and of a non-water miscible phase so as to produce a solution (3) comprising acid compound hydrates and an acid compound depleted gas (10), b) dividing (B1) the solution comprising acid compound hydrates into a hydrate-rich fraction and a fraction rich in non-water miscible phase, c) separating (B1) hydrate-rich fraction (4) from fraction (5) rich in non-water miscible phase, d) heating (R2) the hydrate-rich fraction so as to release gaseous acid compounds (6) by dissociating the hydrates and to produce a water-rich fraction (8), e) mixing (B2) the fraction rich in non-water miscible phase obtained in stage c) with the water-rich fraction produced in stage d) so as to produce the liquid solution used in stage a).

Abstract: Material for thermal insulation including an aerogel obtained by drying an organogel prepared from the pseudopeptides of formula (I). in which R represents a side chain of an amino acid, R1 represents a (C1-C8)alkyl, (C1-C8)alkoxy, aryl, aryloxy, or glycoside group, n=1 or 2 and A represents an aromatic group with one or more rings.

Abstract: The present invention relates to a method of enriching a gaseous effluent in acid compounds, which comprises the following stages: feeding into a contactor a feed gas comprising acid compounds and a composition comprising at least two liquid phases non-miscible with one another, including an aqueous phase, at least one amphiphilic compound and at least one mixture of promoters, establishing in said contactor predetermined pressure and temperature conditions for the formation of hydrates consisting of water, promoters and acid compounds, carrying the hydrates dispersed in the phase non-miscible in the aqueous phase through pumping to a hydrate dissociation drum, establishing in the drum the hydrate dissociation conditions, discharging the gas resulting from the dissociation enriched in acid compounds in relation to the feed gas.
