Abstract: A vertical separator for liquid-gas media comprising a cylindrical housing accommodating a gas discharge pipe coaxial therewith, the pipe and the inner surface of the housing define an annular space divided by a partition wall with openings for gas passage into a liquid-gas space, and a gas space communicating with the internal space of the pipe. The liquid-gas space accommodates blocks for separating the media into liquid and gas, the blocks extending in the radial direction. Each separation block is provided with a gas discharge means accommodated in spaces between adjacent separation blocks and embracing the gas-passage openings in the partition wall.

Abstract: A heat exchanger comprising a number of interchangeable, possibly standardized sections. Each section is made in the form of a bundle of at least partly longitudinally finned tubes, and has strips which serve as spacer elements for fixing the tubes at a certain distance from one another, and bands embracing the tube bundles. The strips have alternating one-sided projections, each projection having the shape of half the perimeter of a rectilineal polygon. Each pair of strips forms cells. The tubes have non-finned portions along the widths of the strips these portions being located at the same level for all the tubes in a section. The cells embrace the non-finned portions of the tubes so that the latter are arranged in parallel rows.
