Full compliance with last sample analysis results
It marks the complete success of the PO/TBA industrialization test of Binhua Group
This is the first PO/TBA technology with independent intellectual property rights in China
It is a milestone in breaking the technological monopoly of international chemical giants
As the core device of the C3C4 comprehensive utilization project, its process is the first domestic co-oxidation propylene oxide technology independently developed by Binhua Group and Tsinghua Institute of Technology

Introduction to isobutane co-oxidation (PO/TBA)
Introduction to isobutane co-oxidation (PO/TBA)The isobutane co-oxidation method (PO/TBA) was first developed by the American ARCO Company in 1967
.
The process uses propylene and isobutane as raw materials to produce propylene oxide and co-produce tertiary butanol (TBA) or methyl tertiary butyl ether (MTBE)
.
The production process mainly includes 6 processes of isobutane oxidation, propylene epoxidation, product separation, purification, catalyst recovery and preparation and tert-butanol treatment
.
Isobutane reacts with pure oxygen to generate tert-butyl peroxide and TBA.
After concentration, tert-butyl peroxide reacts with propylene to generate PO and TBA, and TBA reacts with methanol to obtain MTBE
.
The advantages of this process are that it does not use chlorine as a raw material, has little pollution, and overcomes the shortcomings of the chlorohydrin method, such as serious pollution, large corrosion, and demand for chlorine resources
.
PO/TBA process flow
The PO/TBA process consumes 0.
78 tons of propylene and 2.
77 tons of isobutane to produce 1 ton of propylene oxide, and co-produces 2.
3-2.
5 tons of TBA or 3.
0-3.
2 tons of MTBE
.
This process involves a lot of raw materials and products, and requires a complete industrial chain configuration for upstream and downstream, and the investment is relatively large
.
In addition, how to reasonably digest and utilize a large number of co-products also affects the promotion of this type of technology and the overall benefit of the device
.
Typical PO/TBA processes are mainly mastered by companies such as ARCO, Texaco, LyondellBasell and Huntsman
.
In 2014, Wanhua Chemical introduced Huntman isobutane co-oxidation (PO/MTBE) technology, and built and put into operation a 240,000-ton/year propylene oxide co-production 750,000-ton/year MTBE unit
.
Jinling Huntsman New Materials Co.
, Ltd.
adopted the technology of Huntsman Company, and completed and put into operation in 2017 the MTBE project with an annual output of 240,000 tons of propylene oxide and 742,000 tons of propylene oxide
.
The new PO/TBA technology developed by Binhua has completely independent intellectual property rights, which can increase the profit margin by at least about 10%
.
This industrialization test is of milestone significance for breaking the technological monopoly of international chemical giants, and lays the foundation for the comprehensive promotion of Binhua Beihai project

C3C4 comprehensive utilization project is located in Binzhou Lingang High-end Petrochemical Industrial Park, Beihai Economic Development Zone, Binzhou City, Shandong Province.
It is the first domestic self-developed co-oxidation propylene oxide technology industrialization project.
High-quality raw materials, green production process, products for high-growth new energy and new materials, mainly build 600,000 tons/year propane dehydrogenation to propylene unit, 800,000 tons/year butane isomerization unit, 300,000 tons/year ring Oxypropane (co-produced 780,000 tons/year tert-butanol) unit, 150,000 tons/year synthetic ammonia unit
.
On August 5, 2020, the public works of the project started
