Abstract: 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.

Abstract: Volatile compound emissions from a product that comprises a polymeric material may be reduced or eliminated from the product by heating the product in a subatmospheric pressure environment. The product may be heated in the subatmospheric pressure environment at a temperature sufficient to vaporize a volatile compound contained within the polymeric material such that vapors of the volatile compound are extracted or released from the product.
