Delivery of recovered hydrocarbons from oil fields to refinery, storage and consumption points is related to significant oil products loss. Losses occure all the way from oil production up to receiving them by consumers. The losses are due to outfow, evaporation, weather factors, equipment imperfections, etc. However, according to the case studies, approximately 75% of liquid oil products losses are due to evaporations. Hydrocarbons evaporation is concerned with not only material losses, but also causes environment polluction by toxic hydrocarbons. Therfore, duel losses reduction is an important economic and an environmental problem. Recently, a new tchnology was developed to prevent VOC emissions from tank batteries. The pontoon structures made of oil-resistant rubber-textile or synthetic material are used to prevent VOC emissions. Maintenance and dump of pressure in a pontoon space is carried out by means of the compressor and gas collector. The device was tested in FSU oil fields.
