Pervaporation and vapor-permeation separation of gas-liquid mixtures and liquid mistures by ion exchanged sapo-34 molecular sieve membrane

The invention discloses a method for the pervaporation and vapor-permeation separation of a gas-liquid mixture/liquid mixture by an ion-exchanged sapo-34 molecular sieve membrane, said method comprises the following steps: 1) synthesis of sapo-34 molecular sieve seeds; 2) coating the sapo-34 molecular sieve seeds onto the inner surface of a porous support; 3) synthesis of sapo-34 molecular sieve membrane; 4) performing ion exchange and calcination; 5) using the ion-exchanged sapo-34 molecular sieve membrane obtained in step 4) to perform the separation of a gas-liquid mixture or a liquid mixture by a process of pervaporation separation or vapor-permeation separation. The present method for membrane separation of methanol-dimethyl carbonate has advantages like low energy consumption, being not limited by azeotropic mixture, high methanol flux and high separation factors and thus has great economic value.. ...

Process and apparatus for chemical looping redox combustion with control of the heat exchanges

The invention relates to a process and to a unit for chemical looping oxidation-reduction combustion of a hydrocarbon feed, wherein heat exchanges are controlled through a level variation of a dense fluidized bed of active mass particles in an external heat exchanger (e1, e2), positioned on a transport line carrying particles circulating between a reduction zone (210) and an oxidation zone (200) for the particles in the chemical loop. The bed level variation is allowed through controlled application of a pressure drop on a fluidization gas outlet in the heat exchanger, said pressure drop being compensated by the level variation of an active mass particle bed in a reservoir zone provided on the particle circuit in the chemical loop.. ...
