Flow module

A flow module comprising:

• a plurality of adjacent plate elements;
• at least one of each pair of mutually opposite surfaces of adjacent plate elements having a profiled surface contour formed by a plurality of parallel linear grooves therein, providing a plurality of parallel linear flow ducts in said surface, defined by said grooves and by a mutually opposite surface of the adjacent plate element;
• a plurality of feeding and removal ducts for alternately charging flow ducts between adjacent surfaces of consecutive pairs of plate elements with first and second fluids, said feeding and removal ducts being formed by mutually aligned openings in respective plate elements, which openings extend across substantially an entire end area of said flow ducts, whereby separate feeding and removal spaces are formed;
• a plurality of seals which seal the flow ducts and feeding and removal ducts;
• and
• a plurality of webs arranged in the openings which form the feeding and removal ducts in the respective plate elements, a surface of said webs being aligned below the surface of said respective plate elements.
