Dalian Rubber & Plastics Dalian Bingshan Rubber & Plastics Co., Ltd. (abbreviated as "Da Rubber"), formerly known as Dalian Rubber and Plastic Material Machinery Factory, was founded in 1907. Since 1955, it has been producing rubber and plastic machinery. It is a leading factory in China's rubber and plastics machinery industry. Since the founding of the People's Republic of China, more than 60 kinds of domestic first rubber and plastic machinery have been born here, and can produce various large and medium-sized equipment for the automotive, petrochemical, agriculture, water conservancy, wire and cable, building materials, and packaging industries. The main products are nearly 150. There are more than 300 specifications for various varieties.
Domestic production of ethylene equipment Over the past 20 years, attempts to localize ethylene equipment have not stopped, but the development of China's ethylene equipment has gone through a detour. In the mid-1970s, when China imported three sets of ethylene equipment with an annual output of 110,000 to 300,000 tons, it began to develop large-scale ethylene complete sets of equipment. The former State Development Planning Commission decided to trial production of 110,000 tons/year of ethylene equipment based on Liaoning. . Due to over-emphasis on regional integration, it failed to organize and arrange preferential arrangements nationwide. Some equipment failed to deliver on time or quality was not good. This made the trial of the large-scale ethylene plant complete with no success. The petrochemical sector imported a complete set. Ethylene equipment.
In 1976, the former unit department and the flammability department jointly set up an ethylene equipment design group with an annual output of 300,000 tons. However, since this project was not formally approved, although a new batch of equipment has been developed, due to the required investment and materials, The equipment could not be solved. In the end, this project had to be discontinued.
In July 1983, the State Council once again listed 300,000 tons of ethylene complete sets of equipment as a major set of technical equipment construction projects. In July 1987, the ethylene special leadership team decided to list six tasks, including “accelerating the development of key equipment for ethylene crackerâ€, as a key issue for the major technical equipment ethylene project “July 5thâ€.
In 1988 and 1989, ethylene cracking furnaces with an annual output of 10,000 tons and 20,000 tons were put into use at Liaoyang Petrochemical Company and Gaoqiao Chemical Plant respectively. The main technical indicators reached the international advanced level in the 1980s, and the localization rate reached 90%. This indicates that China has made significant progress in the development of large-scale ethylene plants.
During the "Eighth Five-Year Plan" period, relevant departments completed the cracking of the 40,000 tons/year cracking furnace in Liaohua.
During the "Ninth Five-Year Plan" period, it also completed the cracking of the 60,000-ton/year cracking furnace in Yanshan and Liaocheng, and the localization rate reached over 90%.
At present, Sinopec Group is working with Lummus Corporation in the United States to produce 100,000 to 120,000 tons of large-scale cracking furnaces to prepare for a million-ton large-scale ethylene project.
Basic configuration of a million-ton large-scale ethylene plant The basic configuration of a million-ton large-scale ethylene plant consists of three main production facilities, including 800,000 to 1 million tons of ethylene cracker and 400,000 to 600,000 tons of polyethylene per year. Equipment, 400,000-600,000 tons / year polypropylene plant, and auxiliary facilities such as air separation plant, thermal power station, air compression station, water circulation system, sewage treatment system, etc. The process equipment in these devices is divided into petrochemical special equipment, petrochemical general equipment and instrumentation.

Among them, major key equipment includes: 9 ethylene cracking furnaces with a capacity of 150,000 tons/year; 1 cracking gas compressor; 1 propylene compressor; and 1 ethylene compressor. There are also a number of large-scale towers such as propylene distillation towers, ethylene distillation towers, gasoline dephlegmators, quench oil towers, quench water towers, and more than 20 ethylene cold boxes.
400,000 to 600,000 tons/year of polyethylene equipment totals about 490 sets, including mainly polymerization reactors, 16 towers, 62 heat exchangers, 61 containers, 35 compressors, fans, and 48 pumps. One set of DCS automatic control system. Among them, major equipment such as gas-phase reactors, rotary dryers, cycle gas compressors, ethylene circulation compressors, centrifuges, extrusion granulators, packaging palletizing units and so on.
