Shaanxi Dongxinyuan Chemical’s daily oil production exceeds 1,600 tons Author/Source: Coal Tar Deep Processing and Hydrogenation Technology Collaboration Group Date: 2020-07-06 Clicks: 4 On July 4, good news came from Shaanxi Dongxinyuan Chemical Co., Ltd.: the output of oil produced through coal tar hydrogenation per shift was 548 tons, resulting in a daily output of 1,610 tons – thus breaking through the 1,600-ton mark for the first time and setting a new record in the company’s production history. This marks another update to the highest production capacity record for facilities in this industry in China, following the 1,318 tons per day recorded in September 2019 and the 1,413 tons per day achieved in February 2020. Shaanxi Dongxinyuan Company is the only modern coal chemical project under Shaanxi Coal Group in the Fugu area of northern Shaanxi, which utilizes coal tar hydrogenation to produce fuel oil. In recent years, guided by the advanced philosophy centered on \"scientific management + science and technology as the primary driving force for development,\" the company has taken \"striving for excellence, never being satisfied, and striving to be the best\" as its goals for growth and motivation. It has vigorously promoted the spirit of \"staying committed to ideals and daring to explore new paths.\" Relying entirely on its own technical capabilities, it has pursued independent innovation, self-developed solutions, and hands-on implementation, achieving a series of groundbreaking achievements in the industry related to the hydrogenation of coal tar to produce fuel oil, as well as in the sustainable and comprehensive utilization of coal on a differentiated basis. By implementing technological upgrades related to the comprehensive blending and pyrolysis of raw coal, the company can reduce the cost of raw coal by 10% ； By implementing the technological upgrade of using desorbed gas as a substitute for furnace gas, 100% of the waste gas can be utilized in a scientific and effective manner, resulting in a doubling of the hydrogen production volume and a 50% reduction in hydrogen production costs ； The hydrogen production capacity has been increased by 50% through the successful industrial application of oxygen-based hydrogen production technology and the adoption of adsorption-based resistance-reduction techniques ； Through the retrofitting with hydroprocessing fine-tuning technology, the capacity for producing fuel oil via hydrogenation was increased by 30%. After successfully completing the annual major maintenance and upgrades in June this year, a new upgrade to the coal tar hydrogenation production capacity was achieved in one go, pushing the industry to a new level. According to the company’s head of production technology, the new record for daily output of fuel oil produced through the hydrogenation of coal tar has been achieved as a result of technical upgrades and improvements in process operations. This represents a significant step forward for the company on its path toward higher production volumes and improved efficiency in the production of fuel oil from coal tar, with the goal of achieving top-quality development. Striving for excellence without cease, Dongxinyuan Company will continue to innovate. It is expected that in two days, the daily oil production volume will exceed 1,700 tons, and it may even reach 1,800 tons per day, thus helping to drive further development in the clean and diversified utilization of coal by Shaanxi Coal Group Company.
