ABSTRACT:
A device for catalytic dehydrogenation of a C.sub.2+ paraffinic cut with an improved system for cooling the effluent is applicable, for example, to the synthesis of methyl tert-butyl ether. Liquid charge 12 is evaporated in the calandria of a heat exchanger 13 in the optional presence of at least one part recycled hydrogen 15, then optionally compressed in a compressor 14 before being pre-heated in an exchanger 41 by effluent 1 and introduced into a dehydrogenation reactor 40. The effluent cooled in the tubes of exchanger 13 can be mixed with a cryogenic phase 17 resulting from the isentropic expansion of a hydrogen-rich phase separated in a separator 8, the hydrogen optionally being recycled to the calandria of the heat exchanger. The olefins recovered with the unconverted paraffins are stabilized in a column 20.
