Drying oil the allylic radical intermediates are less stable (i.e., slower to form). The early stages of the drying process can be monitored by weight changes in an oil film. The film becomes heavier as it absorbs oxygen. Linseed oil, for instance, increases in weight by 17 percent. As oxygen uptake ceases, the weight of the film declines as volatile compounds evaporate. As the oil ages, further transitions occur. A large number of the original ester bonds in the oil molecules undergo hydrolysis, releasing individual fatty acids. In the case of paints, some portion of these free fatty acids (FFAs) react with
Narva Oil Plant shale per year. It would produce 290,000 tonnes of shale oil and 75 million cubic meters of oil shale gas per year. The cost of the new oil plant is approximately 3 billion Estonian kroons (€191.7 million, US$264.2 million). The construction was launched in the second half of 2009, and the new Enefit280 plant was commissioned in 2012. The first barrel of shale oil was produced in the new plant on 20 December 2012. Narva Oil Plant Narva Oil Plant (), a subsidiary of Eesti Energia, is a producer of shale oil from oil shale. It operates a commercial scale
