Surging along with the world energy sources price, manufacturing enterprise adopts the concentrator of economic benefits and social benefits, triple effect or multiple-effect to reduce the consumption of steam or other energy more and more.Organic products such as some biochemical industry product such as pyruvic acid, acetate, ethyl acetate belong to volatile products, in the process that concentrates easily along with secondary steam runs off, cause product loss, influence the product recovery rate, cause the rising of production cost also to bring pollution simultaneously environment.For concentrating of this series products, the method that adopts is control evaporating temperature and vacuum usually, reduces the volatilization of product as far as possible.
Under the not high situation of enrichment ratio (weak solution state), the product acid of taking out of is not a lot, but work as along with concentrating that concentration reaches and when surpassing certain content, product acid that the indirect steam that evaporates is taken out of or ester just get more and more, the loss of product also gets more and more.In order not allow these product loss and contaminated environment, the method for proposition often, the condensed water of collecting these indirect steams recycles by other method again, but the energy resource consumption meeting increases greatly.
With pyruvic acid simmer down to example, 1000kg contains the aqueous solution of pyruvic acid 4%, be concentrated into 50% concentration, and pyruvic acid content is not higher than 0.2% in the control indirect steam condensed water, if the first step adopts triple effect to concentrate, be concentrated into 16%, the second step of pyruvic acid concentration employing rectifying mode and be concentrated into pyruvic acid concentration 50%, the consumption of steam is 557kg, can not make us accepting.
