Abstract

The invention provides an integrated system for preparing a dehydrogenated product from an alcohol, the integrated system comprising a heat integration system for heat transfer from at least one heat source to the at least one heat sink. The at least one heat sink includes a feed stream comprising an alcohol and/or an electrolyser system having an electrochemical cell configured for carrying out a partial dehydrogenation process to produce a product stream comprising hydrogen and a co-product stream comprising a dehydrogenated product from the alcohol of the feed stream and/or an infrastructure for handling and/or storing the co- product stream. The at least one heat source includes a hydrogen fuel cell for generating electricity from the product stream of the electrolyser system, wherein operation of the hydrogen fuel cell generates heat, and/or the electrolyser system, wherein the electrolyser system is configured to operate the electrochemical cell so as to generate heat.
