DEVICE AND METHOD FOR OPTIMISING THE CIRCULATION OF A SUSPENSION IN A PLANT COMPRISING A THREE-PHASE REACTOR

摘要

The invention concerns a plant for chemical conversion of a feed, comprising a reactor (2) containing a slurry consisting of at least a suspension of at least a solid in a liquid, a gas supply, a circuit, external to the reactor, for continuous circulation of a slurry flow, said slurry being drawn in at least a point (A) and reintroduced at least partly in at least another point (B), a compartment for separating at least a fluid from the slurry passing through said external circuit, said plant further comprising: means for interrupting the circulation of said slurry in said circuit; means for introducing under pressure at least a fluid for draining off the slurry contained in the circuit, means for circulating the slurry in said external circuit in conditions such that the Reynolds number is higher than 2500.
