The internals of the tower are the internal components of the tower. Compared with the huge air separation, compressors and other equipment, the tower internals can be called “dwarvesâ€. However, in such "small" products and "small" industries, Ningbo Shengye Petrochemical Equipment Co., Ltd. has written a large number of articles, broke out of the big market, became the leader in the industry, and has become increasingly famous. . From 2002 to 2005, the company's output value increased at an annual rate of 20% to 25%. The company has successively won the national honorable and honorable public satisfaction unit, quality credit double protection demonstration unit and other titles, and took the lead in the industry through the ISO9001: 2000 Quality Management System Certification.
Small Business Drives Big Industry Ningbo Yongye Company was established in 1989. Its predecessor was Zhenhai Tower Internal Parts Factory, the third construction company of Sinopec. It is a company that develops and produces containers and tower equipment for oil refining, chemical, pharmaceutical and air separation industries. The professional companies of the internals and towers, the products mainly include various materials, types and specifications of the trays, structured packing, bulk packing, distributors, pipeline fittings and other special and non-standard equipment accessories.
Hangzhou Hangzhou Oxygen Co., Ltd. is the “biggest†in the manufacturing of air separation equipment in China. In the past, the tower internals in the water cooling towers, air cooling towers and cryogenic rectification towers of Hangyang Oxygen Air Separation Plant were all processed and manufactured by other units. Later, Hangzhou Oxygen Co., Ltd. learned that Ningbo Haoye Company has strict management, advanced processing equipment, high-quality employees, and good after-sales service. It gradually transferred this part of its business to Ningbo Yuye Company. After cooperation with Hangyang Oxygen, Ningbo Yuye Company made further improvements to the process and production molds, and purchased a batch of advanced processing equipment, so that the production of tower internals products reached the standards of imported products and was highly evaluated by Hangyang Company. . At present, the tower internals, distributors and other equipment in Hangyang Oxygen Company's large-scale air separation plant with a capacity of over 20,000 m3/h have all been handed over to Ningbo Yanye.
On one occasion, Hangzhou Oxygen Company undertook a contract for a large-scale air separation plant for a Hungarian company. The center hood with a diameter of 200 mm was manufactured by a domestic company. The manufacturing period of the contract was 2 months, and the contract amount was about 40,000 yuan. However, after signing the contract for more than one month, the company found Hang-Oxy, saying that the goods could not be delivered on time. Hangzhou Oxygen Company was anxious and immediately held an emergency meeting. Some experts suggested that the company could give it a try and it was only 20 days before the delivery date. In order to grasp the initiative, Hangzhou Oxygen Company gave 15 days delivery time. After Ningbo Ningbo Yeye Company got the task, it immediately organized technical personnel to formulate technical solutions for mold design and production, and this was taken as the number one task of the company. Working together, working overtime, it took only 10 days to complete the task, and the cost was only around 10,000 yuan. A few months later, the Hungarian company sent a call to Hangoxing that the use of the device was better than expected.
As the joint venture between Ningbo Yanye and Hangyang greatly promoted the improvement of the manufacturing capacity of air separation equipment in China and promoted the technological advancement and development of the entire industry. Relying on the Hangyang Oxygen Company, the tower internals produced by Ningbo Haoye Company are also exported to Indonesia, Pakistan and other countries.
As the popularity and reputation increased, it attracted the attention of the internationally renowned air companies. Air Liquide (China) also handed over the internals of its air separation equipment to the Ningbo Industrial Co., Ltd., after several cooperations. The inner parts such as the packing cover and the mist catcher produced by Shengye Company have become the exempt products of Air Liquide China.
Small Products Exported to Large Markets In addition to the air separation equipment sector, internal products produced by Ningbo Haoye are also widely used in petrochemical, chemical, and fertilizer industries.
The separation tower, heat exchange tower, scrubber tower, dehumidification tower, and decarburization tower in the petrochemical plant have a direct relationship with the separation, heat exchange, washing, dehydration, and decarburization effects of the tower internals. Therefore, the tower internals The level of technology is the key to the use of towers, the conservation of energy, and the protection of the environment.
Zhenhai Refinery's 800,000-ton/year hydrocracking unit is the first domestically produced unit in China. Its 8 million tons/year oil refinery and 3 million tons/year catalytic cracking unit were the largest single oil refinery units in China at the time, and these units More than 70% of the tower internals are manufactured and manufactured by Ningbo Silicon Industry.
In the aromatic extraction facility of the Nanjing Yangba Integrated Project known as the Asia’s first tower, the 7.2-meter internal bridge fixed beam with a diameter of 7.2 meters was originally manufactured by other manufacturers. However, since the products produced cannot meet the design requirements, the owner can only Pick the "high man." After hearing of this incident, the industry company bravely took up the burden. In the case of tight schedules and heavy tasks, they have sincerely cooperated with the design institutes to overcome the technical difficulty of a road and finally completed their tasks on schedule. This move made the industry company's reputation soaring.
In 2005, among the 168 domestic suppliers, Haoye Company was selected as one of the top ten suppliers by Sinopec Tianjin Petrochemical Company.
Small-scale technology to create a great benefit of good products, there must be good technical support. In more than ten years, Ningbo Haoye Company has cooperated with domestic universities and colleges and developed a batch of new products, and some have also obtained national patents. For example, in cooperation with East China University of Science and Technology, the company developed patented patented float valve technology; cooperated with South China University of Technology to develop patented conjugated ring packing technology; and cooperated with Zhejiang University of Technology to develop and produce DJ composite trays that can be used with the United States' MD Tower. Compared with the disk, it is widely used in domestic chemical and pharmaceutical production facilities; the SL valve trays developed in cooperation with the University of Petroleum (Beijing) and Lanzhou Institute of Chemical Machinery are listed as major projects for Sinopec’s “Eighth Five-Year Plan†project. In the promotion of oil refining and chemical plants, great economic benefits have been achieved.
In addition to processing and manufacturing tower internals, Haoye Company also continuously expands new business areas to enable companies to develop rapidly.
In 2004, the company cooperated with Zhenhai Refining & Chemical Company to jointly develop a new type of laminated air cooler, replacing 2 coolers that originally needed to be replaced by one. The floor space was small and the cost was reduced by 50. About %, but the heat transfer effect has increased by 20% to 30%. Due to the outstanding advantages of this cooler, Zhenhai Refining & Chemical has used more than 30 units.
Ningbo Yuye Company is the first domestic company to adopt the automated numerical control production process technology. On the basis of years of experience in processing and manufacturing, the company also made a number of improvements to the processing equipment, which greatly improved the production efficiency. As originally used in ordinary wire-cutting machines to process new types of strips in tube-type heat exchangers, 10 machines can process only about 200 meters a day. Currently, the company adopts a new type of mold punching machine developed by the company. Two people can process one day. 2000 meters, ergonomic increase of 100 times, accuracy also increased by more than 1 times, production costs greatly reduced.
Chen Guocong, general manager of the company, believes that small industries can make great contributions, creating high efficiency, the key is to have advanced technology products, coupled with excellent quality and good service. Today, the company's "boat" is braving the wind and waves in the market and bravely marching forward.
