POLYMERISATION REACTOR WITH HEAT EXCHANGE JACKET

摘要

A tubular reactor for use in polymerisation reactions is described, having a design pressure P R of 40-65 barg, at least a portion of which is oriented vertically and at least part of which vertical portion is surrounded by a concentric jacket for the passage of cooling fluid, wherein the design pressure in barg of the jacket P J is less than 0.0018.P R 2.25 . Another aspect of the invention concerns a tubular reactor for use in polymerisation reactions having a design pressure P R of 40-65 barg, at least a portion of which is oriented vertically and at least part of which vertical portion is surrounded by a concentric jacket for the passage of cooling fluid, wherein the actual thickness of the reactor wall is either no more than 2mm greater and/or no more than 10% greater than the minimum wall thickness required to withstand the design pressure P R as calculated according to the ASME Boiler and Pressure Vessel code.
