Abstract (en)
[origin: EP1939412A1] The heat exchanger for cooling of a cracking gas in an ethylene plant, comprises heat exchanger tubes (1), which are inserted at its ends in tube plates (2, 3) and are surrounded by a jacket (4), and end chambers (5, 6) intended for feeding and exhaust of the gas. The cracking gas flows through the heat exchanger. The end chambers are limited at both end faces by the tube disk. Water as a cool medium flows through the interior of the exchanger, which is separated by a separator (7) into two subspaces lying one behind the other in flow direction of the cracking gas. The heat exchanger for cooling of a cracking gas in an ethylene plant, comprises heat exchanger tubes (1), which are inserted at its ends in tube plates (2, 3) and are surrounded by a jacket (4), and end chambers (5, 6) intended for feeding and exhaust of the gas. The cracking gas flows through the heat exchanger. The end chambers are limited at both end faces by the tube disk. Water as a cool medium flows through the interior of the exchanger, which is separated by a separator (7) into two subspaces lying one behind the other in flow direction of the cracking gas. The separator is extended perpendicularly to the exchanger tubes. The subspaces are provided with a supply- and removal connection for the cooling medium. A boiling- and feeding water flow through the subspace and other subspace lying on the gas entrance side. The subspaces are connected over a supply- and removal line with water/stream drum. The cooling medium permeates the separator between the two subspaces for passages. The pressure of the feeding water is larger than the pressure of the boiling water. The separator is formed as a non-supporting component. An opening is present between the outer circumference of the separator and the inner diameter of the jacket. The exchanger tubes are implemented with clearance though the openings in the separator.
