The report of the 20th National Congress of the Communist Party of China pointed out that the implementation of industrial foundation reconstruction projects and major technical equipment research projects will support the development of specialized, special and new enterprises, and promote the high-end, intelligent and green development of the manufacturing industry. Lanshi Heavy Equipment deeply studies and implements the spirit of the 20th National Congress of the Communist Party of China, focuses on serving the national strategy, improves R&D and manufacturing capabilities, and helps the high-quality development of the equipment manufacturing industry.

Relying on advanced manufacturing technology and excellent product quality, Lanshi Heavy Equipment developed and completed the Sinopec Fujian Gulei Petrochemical Project in 2020. Two dehydrogenation reactors for the styrene plant of 600,000 tons per year have achieved good results after being put into operation, and have been highly praised by the owner. After being awarded the title of "Excellent Supplier", after two years, as a strategic partner of Chambroad Holding Group, Lanshi Heavy Equipment successively took over two units of the 600,000-ton/year styrene plant of Jingbo Holding Group Shandong Zhongtai Chemical The development task of the dehydrogenation reactor and the feed vaporizer of the two reactors, the equipment process package adopts the Badger technology of the United States, the reactor specification is larger than before, the diameter is higher, the tonnage is higher, and the manufacturing requirements are more stringent. Among them, the feed vaporizer adopts a new chemical technology and structure, which is the first set of equipment in the world.

Zhongtai Chemical Styrene Plant Dehydrogenation Reactor

The feed vaporizer is designed by the R&D and sales center of Lanshi Heavy Equipment. From process calculation, vibration analysis, structure optimization to strength design, etc., the most advanced design method in the industry is adopted at present, and the finite element analysis of the whole equipment is carried out. During the product development process, Lanshi Heavy Equipment Qingdao Co., Ltd. strictly controlled all links from preliminary preparation, program demonstration, test experiment, production and manufacturing, inspection and testing, and combined with Gulei Petrochemical project product manufacturing experience, developed a rectangular tube box and inlet transition The manufacturing technology of tubes and large rectangular tube sheets, through various experiments, successfully completed the butt joints between tube sheets and shells, the all-position welding technology of tube boxes and tube sheets, and the overall furnace heat treatment process for irregular equipment, etc., ensuring Product quality and manufacturing progress.

Zhongtai Chemical Styrene Plant Feed Vaporizer

On February 22, 2023, the product completion acceptance meeting and shipping ceremony of the project was held in Lanshi Heavy Equipment Qingdao Company, leaders from Chambroad Holding Group, Chambroad Petrochemical, China University of Petroleum (East China), East China Design Institute and other units and industry leaders The experts listened to the report on the R&D, design and manufacturing of the reactor feed vaporizer. After on-site inspection, discussion and questioning, the participants and experts agreed that: the 600,000-ton/year styrene unit (Badger process) feed vaporizer of Shandong Zhongtai Chemical Technology Co., Ltd. developed by Lanshi Heavy Equipment meets the acceptance requirements and has condition.

At the delivery ceremony, Geng Zhaoqiang, General Manager of Materials and Equipment Management Center of Chambroad Holdings Group, Zhang Kai, Deputy General Manager of Lanshi Heavy Equipment, and Zhang Kai, General Manager of Qingdao Company, delivered speeches on behalf of the owner and R&D and manufacturing units respectively.

The dehydrogenation reactor and the world's first set of styrene plant reactor feed vaporizer were successfully developed in Lanshi Heavy Equipment, which further improved the equipment development capability of Lanshi Heavy Equipment Styrene Plant, and also marked Lanshi Heavy Equipment Badger Technology Styrene The R&D, design and manufacturing capabilities of device products have reached the international leading level.
