摘要： The present invention relates to a process for continuous metathesis or disproportionation of olefins, comprising at least 2 phases, a reaction phase a) carried out in a zone comprising at least one reactor containing at least one fixed bed of catalyst and a regeneration phase b) carried out in a zone comprising at least one reactor containing at least one fixed bed of catalyst, characterized in that at least one reactor passes from one phase to the other in alternation. In FIG. 1, the feed containing olefins traverses reactor R1 in riser mode. The feed to be treated containing olefins is introduced into reactor R1 via line 1a. In this reactor, the olefins contained in the feed undergo metathesis or disproportionation, then the effluent leaves the circuit via line 11. Simultaneously, reactor R2 is placed in catalyst regeneration phase, the different regeneration gases are introduced into reactor R2 via line 2b and leave this reactor via line 2c. Passage from the operating phase of a reactor to the catalyst regeneration phase thereof is carried out as follows: the reactor for which the catalyst is to be regenerated is isolated from the remainder of the apparatus, the hydrocarbons contained in the reactor are evacuated, then the reactor is purged. Said reactor is then connected to a regeneration loop and undergoes regeneration of its catalyst, and at the end of the regeneration phase, the reactor and the regeneration loop are purged.

摘要： Process for dehydrating/fractionating a low-pressure wet natural gas containing “heavy” constituents and “light” constituents includes a stage a) in which at least a fraction of the wet gas at temperature T0 is contacted with an aqueous liquid phase L'1 containing methanol, the gas carrying along substantially all of the methanol contained in phase L'1. In a stage b), the gas from stage (a) is cooled to a temperature T1 lower than temperature T0, producing a gas phase G1 at equilibrium with a hydrocarbon-containing liquid phase L1 containing C3+ and an aqueous liquid phase L'1 containing methanol. In stage c), phase L'1 is sent to stage (a), and in stage d), said phase G1 is fractionated by distillation carried out by continuous thermal exchange with a cooling fluid, so as to extract the “light” constituents (gas phase G2) and the “heavy” constituents (condensed phase L2).

摘要： In a process for dehydration/fractionation of a wet natural gas containing heavy constituents and light constituents, In the presence of methanol, aqueous liquid phases are combined and the resultant combined aqueous liquid phase contacted with the first part of the gas to be scrubbed, which carries along the major part of the methanol, which allows to collect practically pure water. Before this step, all or part of one or both of the aqueous liquid phases and/or all or part of the aqueous liquid phase from a washing zone is sent to a distillation stage where practically pure methanol is collected at the top and a methanol-depleted aqueous liquid phase is collected at the bottom prior to being sent back to the first stage or used for the washing stage.

摘要： For the separation of acid, carbon dioxide and/or hydrogen sulfide from a gaseous mixture comprising at least one lighter gas, e.g. methane, the gaseous mixture (1) is precooled at least once during a heat exchange operation E2; the resultant precooled gas mixture, flowing upwardly is cooled and rectified simultaneously in an approximately vertical heat exchange zone (ER) forming a downwardly-flowing countercurrent liquid reflux; the resultant rectified gaseous fraction (8) depleted in acid gases and enriched in light gas is collected at the top of the vertical exchange zone; and (d) a liquid fraction (4) enriched in acid gas components is collected at the bottom of the exchange zone. The collected liquid fraction (4) can be expanded and evaporated to provide cooling. The system has particular application for the treatment of natural gas or in petroleum refining or recovery operations.
