Polymerisation reator design

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.
