Described are a high pressure carbamate condenser, urea plant, and urea production process. The high pressure carbamate condenser as described is of the shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.

A condenser includes a fluid inlet in an upper manifold and a fluid outlet in a lower manifold. The condenser includes multiport tubes provided with a plurality of separate flow channels which are delimited by outer opposite side walls and internal intermediate walls extending between the outer opposite side walls of the tubes. The multiport tubes define a channel space between them. A plurality of cooling plates extend between the upper manifold and the lower manifold. The cooling plates are in thermal contact with the multiport tubes to receive a heat load from fluid in the flow channels. The cooling plates have outer edges which protrude out from the channel space and are directed away from the channel space.

A mobile vacuum distillation unit for extracting, condensing, and collecting volatile organic compound vapor emissions from one or more polymer-containing articles includes a shell that defines an enclosed interior space and is mounted to a transportable support platform, a vacuum distillation vessel, a condenser, a condensate storage tank, and a vacuum pump system in fluid communication with a vacuum distillation chamber of the vacuum distillation vessel. The vacuum distillation chamber that includes the one or more polymer-containing articles from which the VOC vapor emissions are extracted may be heated by an exhaust gas heat exchanger if the transportable support platform is connected to and hauled by a tractor unit powered by a diesel engine. A method of using the mobile vacuum distillation unit to extract VOC vapor emissions from one or more polymer-containing article during transportation of the one or more polymer-containing articles between geographically separate destinations is also disclosed.
