摘要： A method of deacidizing a gaseous effluent comprising acid compounds where the gaseous effluent is contacted in C1 with an adsorbent solution so as to obtain a gaseous effluent depleted in acid compounds and an absorbent solution laden with acid compounds, the absorbent solution being selected for its property of forming two separable phases when it has absorbed an amount of acid compounds and when it is heated. The absorbent solution laden with acid compounds is then heated in E1 and E3 so as to separate two fractions: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds. These two fractions are then separated in BS1. The second fraction is regenerated in C2 so as to release part of the acid compounds, and the first absorbent solution fraction and the regenerated absorbent solution are recycled as absorbent solution.

摘要： A process for transporting a fluid in a pipe under conditions where hydrates may form. In the process, the pipe fluid contains at least one of a gaseous hydrocarbon or liquid hydrocarbon and water and the water content is less than the liquid hydrocarbon content. The process includes the steps of 1) adding a dispersive additive in a hydrocarbon solution to the fluid to be transported, so as to form an emulsion, 2) transporting the liquid and gaseous hydrocarbons in the presence of water and the hydrates, 3) separating the gas phase, the hydrocarbon liquid in excess and a liquid hydrocarbon phase comprising the hydrates and the dispersing additive, and 4) separating the liquid hydrocarbon phase comprising the hydrates and the dispersing additives. The liquid hydrocarbon phase comprising the hydrates is separated by dissociating the hydrates to form a water-in-oil emulsion, the additives being solved in the oil or liquid hydrocarbon, and breaking the water-in-oil emulsion so as to obtain an aqueous phase and a liquid hydrocarbon comprising the additives. Finally the liquid hydrocarbon phase containing at least part of the dispersing additive from step 4, is recycled to a point in the pipe.
