Sinopec Successfully Completes China's First Industrial Application of Crude Oil Steam-Cracking Technology
- The chemical yield of nearly 50 percent has reached internationally-advanced levels.
- The technology significantly shortens the production process, lowers production costs and reduces carbon dioxide emissions.
- Sinopec's next step is to build a million-ton industrial demonstration plant.
The technology converts crude oil directly into ethylene, propylene and other chemical products ("crude-to-chemicals") and realizes the first industrial application of crude oil steam-cracking technology in
The crude oil steam-cracking technology is one of the "crude-to-chemicals" solutions which "skips" the traditional crude oil refining process to directly convert crude oil into valuable chemical products like ethylene and propylene – analogous to making bread directly with wheat and eliminating the flour grinding process. This approach will greatly shorten the production process, lower production costs and significantly reduce energy consumption and carbon emissions.
The technology was developed and engineered by Sinopec's
A basic raw material of chemical products, ethylene is coined the "mother of the petrochemical industry," and is one of the key benchmarks to measure the development level of a country's petrochemical industry. As people's living standards continues to improve, the global demand for chemical products is also growing, and as basic raw materials, the demand for ethylene and propylene has also increased accordingly. In general, the raw materials needed for producing ethylene and propylene must go through the crude oil refining process at the refineries, the production process of which is not only longer, but also only 30 percent of the crude oil is used to produce the chemical raw materials.
Sinopec has always emphasized the R&D and application of "crude-to-chemicals" technologies. In
Similar to the crude oil steam-cracking technology, the chemical yield of catalytic cracking is also about 50 percent, and combining the two technologies is expected to increase the total amount of chemicals produced by crude oil to more than 70 percent, which will become an economically efficient solution for "crude-to-chemicals" conversion in the future.
Sinopec is preparing to carry out the development and engineering design of packaged technology for the production of ethylene by steam-cracking 1 million tons of crude oil at its Tahe company in
For the large-scale ethylene project planned for the future, the crude oil steam-cracking technology will be included in the key technology comparison and selection scheme, which will provide strong support to relieve the contradiction between supply and demand as well as aiding the enterprises' transformation and upgrading, making greater contributions to achieving 'dual carbon' goals.
