Vigorously promote the technological progress of chemical equipment

(1) Assisting government authorities in the digestion, absorption, and localization of large-scale fertilizer import equipment. In the 1970s, China introduced large chemical fertilizer production facilities from abroad. Over the years, relevant state departments and major chemical fertilizer companies have made significant efforts to adapt and localize this imported technology. In recent years, the Association has supported the former National Bureau of Petrochemical Technology and Equipment in carrying out specific tasks related to the selection, project approval, and organization of localization initiatives for large-scale chemical fertilizer projects. The Association has also coordinated the use of technology developed by Quzhou Cooling Tower Company to help localize the cooling towers at Wuzhou Dafang Fertilizer Plant. It has been involved in every stage of the project, from approval to implementation, evaluation, and final acceptance.

The Association has also facilitated collaboration between Jinxi Natural Gas Chemical Company, Shenyang Blower Factory I, and Lanzhou Chemical Machinery Institute to complete the localization of large chemical fertilizer vapor compressors. Currently, these compressors are being manufactured at the Shenyang Blower Factory, with efforts underway to finish installation, commissioning, and acceptance by 2025.

(II) The Collaborative Group for Equipment and Technology Management in the Chlor-alkali Industry has held multiple meetings, exchanges, and seminars on topics such as the continuous development of large-scale production equipment, as well as the digestion, absorption, and localization of ion-exchange membrane caustic soda and C-paste resin introduction technology. Enterprises have reported significant benefits from these activities. Additionally, new equipment such as pusher centrifuges and chlorine compressors has been promoted and adopted within the industry.

(III) The Soda Ash Industry Equipment Technology Management Collaboration Group has organized technical research and exchanges focusing on corrosion issues in soda ash production equipment and related structures. The group has promoted new anti-corrosion materials and equipment like iron pumps and Qin valves, and has made initial progress in addressing equipment protection measures against corrosion.

(D) The Coating Equipment Industry Technology Management and Coordination Group has consistently encouraged collaboration between production enterprises and equipment manufacturers to conduct joint technological research, achieving a series of notable results. Hydraulic couplings and Amar filters used in imported sand mills have been successfully localized, and a new type of horizontal sand mill has been developed. These contributions have helped advance the technology of paint industry equipment.

(V) Power companies have collaborated in organizing various technical exchange activities, summarizing, exchanging, and promoting the localization and scaling up of fly ash remelting technology in fluidized bed boilers at Sanming Chemical Factory’s thermal power plant and Jilin Group’s power plant. They have shared a wealth of successful experiences, particularly regarding desulfurization technology. Notably, the fly ash remelting technology implemented at Jihua Power Plant has shown good results after being applied at Wuhan Gehua Power Plant. Other industry equipment technology management collaboration groups and professional committees under the association have also carried out valuable work, playing an essential role in advancing the development of equipment and power technologies within their respective fields.
