摘要：Fatty acid esterification is effected in a packing-containing column with bothreactor and distillation functions, the process involving production of a stripping gas inthe sump and liquefaction and separation of the loaded gas at the column top into anaqueous fraction and an alcohol-rich fraction, the latter fraction being recycled as astarting material for the esterification and for the production of the stripping gas. Fattyacid (F) esterification is effected in a column (1) with uni- or multi-part packing (3, 4) whichacts both as a reactor and a distillation unit and forms a reaction zone (3) at least in theupper part with the catalyst fixed to the packing, the process involving (i) heterogeneouscatalysis of acid (F) with an equimolar amount or an excess of an alcohol (A); (ii) producinga gaseous alcohol-rich counterstream (50) in the sump by evaporation; (iii) removingwater from the reaction zone using stream (50) which acts as a stripping gas; (iv) at leastpartially liquefying the loaded stripping gas (60) at the top of the column; (v) separatingthe tops product into an aqueous fraction (63) and an alcohol-rich fraction (62); and (vi)recycling the alcohol-rich fraction (62) as a starting material for the esterification and alsofor the production of the stripping gas. An Independent claim is also included for a plantfor production of the ester (E) comprising the column (1) with packing including porouscatalyst carriers (31) and flow channels (32) for the stripping gas (50/) between the
carriers, the reaction being effected in the carrier pores with the treated mixture being adownwards flowing stream (10/) and the stripping gas being an upwards flowing streamsuch that the streams are in direct contact to give a materials exchange.
