The PetroChina Xinjiang Dushanzi 10 million-ton oil refining ethylene million-ton project is an important part of the energy cooperation strategy between China and Kazakhstan, and it is also another landmark project of China’s implementation of the western development strategy. Its start-up construction is of great significance for safeguarding China's energy security and promoting the sustained, rapid, and harmonious development of the national economy. At the same time, it is beneficial to China's oil and petrochemical industry to utilize domestic and international resources, develop domestic and international markets, accelerate structural adjustment, and enhance international competition. force.
The project includes 20 sets of refinery equipment and 12 sets of chemical equipment. The estimated investment is 26.2 billion yuan, of which the refinery part is planned to be completed in 2007 and the chemical part is planned to be completed in 2008. After the project is completed, it can annually produce 5.5 million tons of refined oil, and add 1.82 million tons of chemical products. It is estimated that the annual sales income will exceed 30 billion yuan.
Dushanzi, one of the birthplaces of China's oil industry, has a history of oil extraction and processing for nearly one hundred years. At present, Dushanzi Petrochemical Company has a production scale of one-time processing of 6 million tons of crude oil and an annual production capacity of 2.2 million tons of ethylene. It can produce more than 350 grades of petrochemical products. It is a special oil for ships, high-grade lubricants, and clean fuels. Polyolefin special material production base, the products sell well in domestic and foreign markets. In 2004, the sales revenue of Dushanzi Petrochemical Company exceeded 14 billion yuan, and its profit exceeded 1.3 billion yuan. At present, Dushanzi has become an important petrochemical base in western China.
The rapid development of the Dushanzi petrochemical industry has benefited from the high production and stable production of crude oil produced in the Karamay oil field for many years. In 2002, the crude oil output of the Karamay Oilfield exceeded 10 million tons for the first time, becoming the first large-scale oil field of 10 million tons in the western part of China. This year, crude oil production reached 11.7 million tons. Dushanzi is the receiving terminal of China-Kazakhstan oil pipeline. In September 2004, the Sino-Kazakhstan oil pipeline began to be laid. It is expected that the entire pipeline will be completed in December this year to realize oil transmission with an annual oil transmission capacity of 20 million tons.
Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling functions of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects of metal equipment.
Scale inhibitors can remove scale and prevent the formation of scale, improve heat exchange efficiency, reduce electricity or reduce fuel consumption; Water treatment can also reduce sewage discharge, improve water utilization, generally can save more than 60%,in line with the global demand for energy conservation and emission reduction.
According to the polymeric composition of the scale inhibitor, it can be divided into two categories: natural polymer scale inhibitor and synthetic polymer scale inhibitor. The synthetic polymer scale inhibitor can be further divided into four kinds of carboxylic acid polymer scale inhibitor, sulfonic acid polymer scale inhibitor, phosphorus-containing polymer scale inhibitor and environmentally friendly scale inhibitor.
