A PLATE HEAT EXCHANGER FOR TREATMENT OF A FEED, A PLATE FOR A PLATE HEAT EXCHANGER FOR TREATMENT OF A FEED, A GASKET FOR USE TOGETHER WITH THE HEAT EXCHANGER PLATE AND A METHOD OF PRODUCING A HEAT EXCHANGER FOR TREATMENT OF A FEED

摘要

The present invention relates to a plate heat exchanger for treatment of a feed. The plate heat exchanger including a plate package comprising a plurality of heat exchanging plates arranged successively in the plate package. Each heat exchanging plate defining a first pair of ports located adjacent a first longitudinal edge and a second pair of ports located adjacent a second longitudinal edge. Every second heat exchanger plate being rotated 180 degrees about a centre axis such that respective front sides and rear sides of adjacent heat exchanger plates faces each other. The second pair of ports of each rotated plate match the first pair of ports of the adjacent heat exchanger plate and define passages for vaporized feed, whereas the first pair of ports of each rotated plate match the second pair of ports of the adjacent heat exchanger plate and defining passages for cooling fluid.
