Sanyue Chemical wants to launch the HPPO project!

According to the online approval and supervision platform for investment projects in Shandong Province, on July 29, Shandong Sanyue Chemical Co.
, Ltd.
(hereinafter referred to as "Sanyue Chemical") 150,000 tons/year hydrogen peroxide method propylene oxide project has been put on record
.

As a traditional and old PO key enterprise, Sanyue Chemical currently has 3 sets of chlorohydrin process PO units with a total production capacity of 240,000 tons/year, which will be completed in 2017 or before
.
If the new project is put into operation, the total production capacity of PO will reach 390,000 tons/year
.

The chlorohydrin process has been phased out, and the domestic PO project process has shown a trend of "a hundred flowers blooming"

The chlorohydrin method has low conversion rate, large chlorine consumption, serious equipment corrosion and serious pollution.
The production of 1 ton of propylene oxide will produce 2 tons of waste residue and 40 to 80 tons of chlorine-containing wastewater
.
On the one hand, new projects have been banned from adopting this law; on the other hand, under the circumstance that environmental protection policies have become stricter, some chlorohydrin method manufacturers have been affected to a certain extent due to geographical location and local environmental protection policies, and some Tianjin University Gu, Fuzhou Bay Chlor-Alkali Industrial Chlorohydrin process plant permanently shut down
.

Judging from the PO projects launched in China in recent years, the production process has shown a situation of "a hundred flowers blooming" in recent years
.
The emerging co-oxidation route (PO/SM, PO/MTBE, CHP) and direct oxidation route (HPPO method) have gradually become the mainstream of industry development
.

As mentioned above, when the chlorohydrin process has been eliminated, Sanyue Chemical's PO expansion can only be selected from other processes.
It can be seen that the company's expansion project plans to use the HPPO process
.

High prosperity! Many companies have launched HPPO projects

At present, the total production capacity of HPPO projects under construction in China has reached 1.
45 million tons per year, and it is expected to release production capacity intensively in 2022-2023
.
Among them, Jincheng Petrochemical 300,000 tons/year, Qixiang Tengda 300,000 tons/year, Taixing Yida 150,000 tons/year are expected to be put into operation in 2022; Sinochem International 400,000 tons/year, Sinochem Tianchen 300,000 tons/year It is expected to start production in 2023 (Sinochem Tianchen 300,000 tons/year HPPO project was launched on July 12)
.

In addition, many new entrants such as Weiyuan Co.
, Ltd.
and Huayi Group are also rapidly advancing the HPPO project
.

1.
Weiyuan Co.
, Ltd.

On July 18, Weiyuan Co.
, Ltd.
issued a project investment announcement.
It plans to use the products produced by the company's propane dehydrogenation project as the main raw material, and use the hydrogen peroxide direct oxidation production process to build 300,000 tons/year of direct oxidation propylene oxide, 900,000 tons of propylene oxide.
ton/year hydrogen peroxide device, and supporting public works and auxiliary production facilities
.
The estimated total investment of the project is 3.
53 billion yuan, and the project construction period is 20 months
.

Huayi Group

On May 30, Guangxi Huayi Chlor-Alkali Chemical Co.
, Ltd.
, a holding subsidiary of Huayi Group, announced the environmental impact assessment of the hydrogen peroxide method propylene oxide (HPPO) and polyether polyol integration project.
The total investment of the project is 5.
5 billion, and the construction period is 2023-2025 year, including a 300,000-ton/year propylene oxide unit, using the HPPO method
.

3.
Minxiang Chemical

On March 19, Shandong Minxiang Chemical's 230,000-ton/year hydrogen peroxide and 150,000-ton/year propylene oxide project announced the environmental impact assessment
.
The company plans to produce 230,000 t/a of 50% hydrogen peroxide, and use hydrogen peroxide as raw material to produce 150,000 t/a of propylene oxide, and at the same time by-produce 5,100t/a of propylene glycol, 4,170t/a of propylene glycol monomethyl ether, and 1,388t of propylene glycol isomonomethyl ether /a
.
The project construction period is 24 months; the investment amount exceeds 1.
2 billion yuan
.

4.
Henan Energy and Chemical Industry Group

On February 9, the Puyang Municipal Government and Henan Energy and Chemical Group signed a strategic cooperation framework agreement
.
According to the "Strategic Cooperation Framework Agreement", the group company and the Puyang Municipal Government will focus on promoting 12 new chemical projects with high correlation, high added value and strong driving force.
Among them, 5 projects will be implemented recently, with an estimated total investment of 11.
56 billion yuan.
Including 500,000 tons/year hydrogen peroxide (50%) and 300,000 tons/year propylene oxide (HPPO method) project, the estimated investment is 3.
76 billion yuan
.

Jiahong New Materials

On February 8, Lianyungang Xuwei New District announced the first phase of the Jiahong New Material High-performance New Material Project.
The project is mainly divided into three stages to build 2 sets of 400,000 tons of PO units and 2 sets of 260,000 tons of acrylonitrile units.

.
Since then, the project has made progress in stages: in the first stage, 3 sets of 450,000 t/a hydrogen peroxide plants and 1 set of 400,000 t/a propylene oxide plants are mainly constructed; in the second stage, 3 sets of 450,000 t/a hydrogen peroxide plants are mainly constructed.
There are 1 set of 400,000 t/a propylene oxide unit and 1 set of 260,000 t/a acrylonitrile unit; in the third stage, a 260,000 t/a acrylonitrile unit is mainly constructed
.

Domestic HPPO independent technology is gradually emerging

HPPO process is an internationally recognized green production technology, which has the characteristics of less pollution and mild reaction conditions
.
As mentioned earlier, it will become one of the mainstream processes used in new PO devices in China in the future
.

Currently, BASF and Evonik's HPPO processes are at the forefront of the world
.
However, the international giants, relying on their monopoly advantages, charge extremely high prices for technology transfer.
According to market sources, Sinopec has discussed the purchase of HPPO, but the technology transfer fee will cost tens of millions of euros
.
More than that, the hydrogen peroxide manufacturing technology is also bundled and priced separately
.
And the HPPO project itself is a high-risk project
.
Hydrogen peroxide is very active, and propylene is an explosive substance.
Putting two very dangerous things together can easily explode if the process is uncontrollable
.
It can be seen that the road to innovation is long
.

Although the HPPO process is mainly controlled by foreign companies, domestic companies are also striving to catch up and gradually break through the core process technology of HPPO
.

On the one hand, Changling Refinery, Sinopec Petrochemical Research Institute and Hunan Changling Petrochemical Technology Development Co.
, Ltd.
have jointly developed the hydrogen peroxide direct oxidation method to synthesize hydrogen peroxide (HPPO) technology with independent intellectual property rights for 15 years.
The international monopoly fills the domestic gap
.

On the other hand, recently, the hydrogen peroxide method propylene oxide technology (HPPO) independently developed by Tianchen Company passed the appraisal of scientific and technological achievements organized by Tianjin Science and Technology Achievement Evaluation Center
.
After a comprehensive review, the experts of the appraisal committee unanimously agreed that the overall technology of the research results has reached the international advanced level
.
Tianchen's hydrogen peroxide method propylene oxide technology (HPPO) uses propylene and hydrogen peroxide as raw materials and adopts self-developed catalyst system.
It has strong technological innovation and has obtained 23 Chinese patents
