Shandong Binhua High Purity Isobutylene/Diisobutylene Plant Put into Production

Project Overview and Technical Breakthrough

recently, Shandong Binhua New Material Co., Ltd. 100000 tons/year of high purity isobutylene and 30000 tons/year of high purity diisobutylene the unit is successfully started at one time, the current operation is stable, the process parameters meet the design standards, and the quality of the main products is stable and qualified.

The device uses A series of patented technologies independently developed by PetroChina East China Design Institute it is a milestone breakthrough in the industrial application of domestic technology in this segment. Core innovation focuses on two points:

• raw material self-evaporation heat extraction technology: Reduce the heat load of the reboiler by using the evaporation heat of the raw material, realize the energy cascade utilization, and compress the energy consumption baseline of the device;
• inhibitor circulation pathway optimization: Redesign the cycle route, simplify the operation node, reduce the maintenance cost and operation complexity.

The two innovations work together, the combined effect is remarkable: compared with the conventional process, the comprehensive energy consumption is reduced by about 50%, and the total project investment is saved by about 25% substantial breakthroughs have been achieved in both the dimensions of energy saving and cost reduction.

Industry Significance and Market Impact

the high value-added utilization of carbon four resources has long been a common pain point in the domestic refining industry. High-purity isobutylene, high-purity diisobutylene as synthetic rubber, fuel additives and fine chemicals key raw materials, product premium is much higher than ordinary carbon four mixture, but the production technology threshold is high, energy consumption control is difficult, before the domestic production capacity is relatively limited.

The successful industrialization of domestic patented technology, its industrial significance is reflected in three levels: one is the engineering feasibility of the domestic technology route is verified, and the dependence of similar projects on imported technology is expected to be reduced; two is50% energy consumption reduction and 25% investment compression form a replicable economic model to provide a reference for the subsequent construction of similar devices; three is it is in line with the policy orientation of green and low-carbon transformation in the chemical industry, and injects technical driving force for the comprehensive utilization of carbon four.

For traders and supply chain practitioners the smooth production of the device means that the supply capacity of domestic high-purity isobutylene and high-purity diisobutylene is further enhanced, and the accessibility of domestic sources is improved. It is recommended to continuously track the pace of capacity release of the device and its potential impact on the import dependence and market price of related varieties.
