On that day, the 100,000 tons per year high-purity isobutylene and 30,000 tons per year high-purity diisobutylene production facilities of Shandong Binhua New Materials Co., Ltd., which utilize technology independently developed by CNPC East China Design Institute Co., Ltd., achieved successful commissioning on the first attempt. The facilities are currently operating steadily, with all process parameters meeting the design specifications; the quality of key products such as isobutylene and diisobutylene remains stable and meets required standards. This represents another milestone in the industrial application of the company’s patented technology. The core process of this device utilizes a series of patented technologies independently developed by the company. It innovatively employs a technology for heat extraction through the self-evaporation of raw materials, which effectively reduces the thermal load on the reboiler. This leads to efficient energy utilization, optimizes the circulation path of the inhibitor, significantly simplifies the process, and enhances production efficiency. Compared to conventional diisobutylene production processes, it reduces the overall energy consumption by approximately 50% and cuts the total project investment by about 25%. It performs excellently in terms of energy savings, cost reduction, and efficiency improvement, offering an efficient, economical, and viable technical solution for the high-value utilization of C4 resources. It provides strong technical support for promoting the green and low-carbon transformation of the industry. The successful commissioning and stable operation of this unit represent a successful example of the deep integration of the company’s research and development capabilities with practical engineering applications, highlighting the company’s core strengths in innovation in refining processes and the transformation of patented technologies into practical solutions. In the future, the company will continue to focus on the areas of \"dual carbon and three innovations,\" paying attention to the needs of industry development. It will increase investment in research and development, and keep advancing the industrial application of advanced technologies, thereby helping the industry achieve green, low-carbon development and high-quality growth.
