Overview
Zavod Slantsy is a Russian oil-shale processing and petrochemical enterprise located in the city of Slantsy in Leningrad Oblast. The company was established in 1945 with a strategic role in supplying Leningrad with oil-shale gas, a synthetic gas produced through the pyrolysis of oil shale. Its industrial complex subsequently expanded into power generation, shale-oil production, petroleum-coke treatment, and the manufacture of other chemical products derived from oil shale. A major early development came in 1952, when the first unit of a 75-megawatt oil-shale-fired power plant and the first stage of the oil-shale gas extraction facility were commissioned. From 1955 through 2000, the enterprise produced shale oil using Kiviter technology. The plant depended on oil shale supplied by Leningradslanets, the mining company serving the regional oil-shale industry. In 1970, Zavod Slantsy added petroleum-coke tempering to its activities, broadening its industrial output beyond direct oil-shale conversion. The enterprise underwent a corporate reorganization in 1993, when Slantsepererabatyvayushiy zavod Slantsy was reorganized as Zavod Slantsy OAO. Its energy profile changed in 1998, when the 75-megawatt thermal power plant was converted from oil shale to natural gas. Shale-oil production continued until June 2003, after which the company’s activities were described as focusing on polymeric petroleum resins and distillates, petroleum-coke tempering, and gas-condensate refining. The company’s ownership became an important governance issue in the 2000s. Rosimushchestvo, Russia’s federal property agency, was reported to control 41.75 percent of the shares and 55.7 percent of the voting rights, while Viktor Vekselberg’s Renova Group was reported to control 40 percent from 2007. Rosimushchestvo made repeated efforts to sell its stake, including an auction announced for December 2012. In 2011, an arbitration court connected with the Saint Petersburg Chamber of Commerce and Industry began a supervisory procedure following a lawsuit filed by Gazprom. The available reference material does not establish the company’s present operating status, ownership, product volumes, or current management.
History
Zavod Slantsy was established in 1945 in Slantsy, Leningrad Oblast, as part of the industrial effort to supply Leningrad with oil-shale gas. The gas was made synthetically through oil-shale pyrolysis, making the enterprise part of the region’s fuel and chemical infrastructure. Its development was tied to the local oil-shale mining industry, with feedstock supplied by Leningradslanets. In 1952, the enterprise commissioned the first unit of a 75-megawatt power plant fired by oil shale and opened the first stage of its oil-shale gas extraction plant. These facilities gave the complex both an energy-generation function and a chemical-processing role. Beginning in 1955, the plant also produced shale oil using Kiviter technology. Shale-oil production remained an important activity for several decades, alongside the manufacture of other chemicals derived from oil shale. The company expanded its processing capabilities in 1970 by beginning petroleum-coke tempering. This activity supplemented the oil-shale operations and reflected the plant’s broader role as a regional industrial processor. In 1993, Slantsepererabatyvayushiy zavod Slantsy was reorganized as Zavod Slantsy OAO, marking a transition into a post-Soviet corporate structure. A significant technical change took place in 1998, when the 75-megawatt thermal power plant was converted from oil shale to natural gas. The change reduced the facility’s direct dependence on oil shale for power generation. The company continued to produce shale oil until June 2003. After the end of shale-oil production, its described activities included manufacturing polymeric petroleum resins and distillates, tempering petroleum coke, and refining gas condensate. Ownership and corporate control were prominent issues in the company’s later history. Rosimushchestvo was reported to hold 41.75 percent of the shares, representing 55.7 percent of the voting rights, while Renova Group was reported to hold 40 percent from 2007. The federal agency reportedly attempted several times to sell its stake and scheduled another auction for December 2012. Separately, in November 2011, an arbitration court associated with the Saint Petersburg Chamber of Commerce and Industry began a supervisory procedure after a lawsuit filed by Gazprom. The available sources do not provide a verified account of the procedure’s final outcome or confirm Zavod Slantsy’s current corporate status.
