100 Catalytic Cracking Units Designed by Beijing Design Institute.Since March 1963 when the first 600 000 t/a accordant and parallel fluid catalytic cracking unit was designed, Beijing Design Institute has designed a total of 100 fluid catalytic cracking units. Their capacity ranges from 600 000 t/a to 2 million t/a. Raw materials include distillate dis·til·late n. A liquid condensed from vapor in distillation. distillate a product of distillation. oil, residuum That which remains after any process of separation or deduction; a balance; that which remains of a decedent's estate after debts have been paid and gifts deducted. blended oil, full atmospheric residuum and full vacuum residuum, In these 35 years, Beijing Design Institute has developed several dozen research achievements related to fluid catalytic cracking. 30 of them have won the scientific and technical progress prize of China Petrochemical Corporation and the state, 11 of them have won the patent of the state, and I of them has won the patent of the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. . The technology winning the patent of the United States is exported to the United States and used in Singapore and Korea. 14 fluid catalytic cracking units have won the excellent engineering and design prize of China Petrochemical Corporation and the state, half of them awarded the first prize or gold medal gold medal traditional first prize. [Western Cult: Misc.] See : Prize of the state. 12 technologies' have been included in engineering and design know-how of China Petrochemical Corporation. Beijing Design Institute has greatly enhanced its ability of design and innovation in the process. [n the months from September to December 1983 Beijing Design Institute completed the advanced process of using 100% Daqing atmospheric residuum as feed stock in the catalytic cracking unit of Shijiazhuang Refinery and played a leading role in heavy oil catalytic cracking in China. In March 1995 Beijing Design Institute completed the design of a 50 000 t/a acrylonitrile acrylonitrile /ac·ry·lo·ni·trile/ (ak?ri-lo-ni´tril) a colorless halogenated hydrocarbon used in the making of plastics and as a pesticide; its vapors are irritant to the respiratory tract and eyes, may cause systemic poisoning, and are and 30 000 t/a acrylic fiber unit from the 400 000 t/a propylene propylene /pro·pyl·ene/ (pro´pi-len) a gaseous hydrocarbon, CH3CHdbondCH2. propylene glycol a colorless viscous liquid used as a humectant and solvent in pharmaceutical preparations. unit in Anqing Petrochemical Complex, and played a demonstrative LEGACY, DEMONSTRATIVE. A demonstrative legacy is a bequest of a certain sum of money; intended for the legatee at all events, with a fund particularly referred to for its payment; so that if the estate be not the testator's property at his death, the legacy will not fail: but be payable role in developing chemical fiber products in oil refineries. It is reported that the processing capacity of catalytic cracking units in China holds the second place in the world, only next to the United States. |
