Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** On May 11, 2024, good news came from Lanzhou Petrochemical: the newly built 3,000-ton/year selective molecular sieve production facility produced its first batch of such products, and all of them passed quality tests, indicating that the entire production process was operational and that the facility was successfully brought online on its first attempt. The 3,000-ton/year shaped molecular sieve production facility is an important research project for Lanzhou Petrochemical to promote transformation and upgrading as well as to achieve the goal of \"reducing oil usage and increasing chemical products.\" Designed by Lanzhou Global Engineering Co., Ltd., it utilizes new processes and technologies such as separate mixing and pulping, emulsification and dispersion of crystallization materials, and DCS automatic control to produce ZSM-5 series molecular sieves with special pore structures. Shape-selective molecular sieves are effective active components in the production of propylene additives; they can significantly increase propylene yield and are widely used in the industry. Construction of the project began on July 13, 2023. It was completed and put into operation on April 17 this year, with the first batch of qualified products being produced on May 11. After the installation was put into operation, Lanzhou Petrochemical’s production capacity of shaped molecular sieves increased from 1,000 tons per year to 3,000 tons per year. This enables it to meet the production needs of the catalyst division’s facilities in both the northern and southern locations, thereby laying a solid foundation for increasing the production of propylene additives as well as catalysts used in processes such as DCC and ECC, and for their widespread use. The operation of this project also makes full use of existing resources, reduces external procurement costs, effectively lowers the production cost of catalysts, and enhances their competitiveness in the market. Meanwhile, the optimized and upgraded selective molecular sieve system is capable of producing various types of selective molecular sieves, including ammonium-type and hydrogen-type ones, enabling the compliant discharge of waste gas and wastewater; this will further enhance the environmental control capabilities of the selective molecular sieve installation.
