Recently, Jinhai Deqi, a company in the Ningbo Chemical Industry Zone, was put into trial production, and the mixed carbon produced by Zhenhai Refinery and Chemical Co., Ltd. was processed into cyclopentadiene and pentadiene, which were provided to “Shanhua Resin” and Tianli. Chemicals and other enterprises produce resins and form a complete industrial chain. Through supplemental chain and extension chain investment, Ningbo Chemical Industry Zone has built up the “skeleton” of the vertical petrochemical industrial chain and the horizontal circular economic chain, and nearly 100 companies have formed a “closed” cooperation network.
For a long time, the petrochemical industry in Ningbo Chemical Industry District has been mainly engaged in refining. To build a large-scale petrochemical industrial base with international competitiveness, it is necessary to gather more affiliated companies and lengthen the industrial chain. For this reason, the Chemical Industry Zone has experienced a long period of “building a nest” period, investing 3.5 billion yuan, and has established an integrated structure of public utilities, logistics integration, safety and environmental protection integration, and management services. Since then, the park has set extremely stringent conditions for admission to the park, and it has been “finishing gold” through the development of its products and waste around the leading companies.
The vertical petrochemical industry chain in the chemical industry zone follows the development path of “oil (oil) head (chemical) tailing”, that is, upstream enterprises' products are used as raw materials of downstream enterprises to make maximum use of resources. Nowadays, 80% of products in Zhenhai Refinery can be digested in the park: After the ethylene produced is processed into ethylene oxide by Akzo Nobel, it is provided to other enterprises in the park to produce surfactants and water reducers; Produce phthalic anhydride, a raw material for plastics, dyes, and resins for TEDA, and plasticizers for Aijing and Donglai; provide butadiene to NBR to produce LG. ABS plastic...
As the products continue to be updated and upgraded, the park has attracted more outside companies to come together. Chlor-alkali-producing “Zhenyang Chemical” settled in the chemical industry area and attracted many enterprises to enter the park. “Shanhua Chemical” accepted its hydrogen sulfide, “Siming Chemical” accepted its hydrogen, and “Juhua Technology” accepted its chlorine. Asahi Silicon’s acceptance of its hydrogen chloride; “Detech Chemical” after entering the park, the use of tar to produce carbon black, the results attracted a number of rubber plants as raw materials to settle here. Today, such enterprise clusters are getting larger and larger. As of now, the industrial zone has completed industrial investment of 46.6 billion yuan, with an annual production value of nearly 100 billion yuan.
In addition to the vertical industrial chain, there are four circular economy chains in the Chemical Industry Zone that feature "swallowing, eating, and discarding." The “waste products” in the park are mainly sulfur, tar, waste heat, etc. Today, there are good places to go. The disposal of sulphur once caused a headache in the park. Today, “Shanhua Chemical” and other companies collect it and use it to produce industrial sulfuric acid. Industrial sulphuric acid is sent to enterprises such as “Xinfu Titanium Dioxide” through pipelines, and waste sulphuric acid is sent to Zhenhai Phosphate Fertilizer Plant for production. Phosphate fertilizer. The recovery and utilization of waste heat is also a problem. The park has established a centralized heating pipeline and collected waste heat from companies such as TEDA, SHUHUA, and DETEC along the way and provided it to more than 60 enterprises in the park.
The vertical and horizontal two chains not only increase the product value of the chemical industry, but also greatly reduce the emission of pollutants. After becoming the province's first batch of provincial-level development zones that passed the “811” environmental remediation, the Chemical Zone has become the first batch of national demonstration bases for new industrialization industries.
