Abstract
This invention relates to a process and apparatus for the cooling of polymerization charges in emulsion, suspension, solution, and bulk polymerizations in connection with incompletely filled polymerization reactors or vessels having capacities of 40 m.sup.3 or greater and thermal loads of more than 500,000 kcal/h with the aid of a reflux condenser or cooler which is in communication with the gas space of a polymerization vessel.
Claims9
An apparatus for cooling of polymerization charges in a polymerization vessel having a liquid level and a gas space above said liquid level, comprising a reflux cooler means including a reflux cooler head mounted on the polymerization vessel above said liquid level and in direct open communication with the gas space of the polymerization vessel, a gas conduit means operatively connecting the reflux cooler head with the polymerization vessel and being in communication with the gas space of the polymerization vessel, and means in said gas conduit means for providing a force-feeding of the gas through said gas conduit means, said reflux cooler means and said gas space.
An apparatus for cooling a polymerization vessel which is operated with a liquid level and which has a gas space above the liquid level, comprising a reflux cooler means mounted centrally on top of a hood of the polymerization vessel, said reflux cooler means having a lower portion in direct open communication with the gas space of the polymerization vessel and a gas conduit means operatively connecting an upper head of the reflux cooler means with the gas space of the polymerization vessel and means within said gas conduit means for providing a force flow of the gas therethrough and means for controlling the flow of gas within said gas conduit means.
