Dayuewan Petrochemical to use Honeywell technology

When the project is completed, Dayuewan will be converting nearly all of its vacuum residue to light oil products, representing one of the highest conversion rates in the world. Meanwhile, this project will adopt a range of advanced process technologies to recycle hydrogen and liquefied petroleum gas (LPG) at among the highest rates in the world.

Honeywell UOP is providing basic engineering and technology licensing, as well as technical and start-up services for the project, which includes a 1.4 million tpy Uniflex^TM MC^TM slurry hydrocracking unit to upgrade bottom-of-the-barrel fuel oil into light oil products. This will be fed to a Unicracking^TM unit to produce naphtha for a CCR Platforming^TM unit. The project also includes three Polybed^TM pressure swing adsorption (PSA) units to supply high-quality hydrogen for the Uniflex process. The PSA units are designed to generate 320 000 m³/hr of hydrogen.

“This project will enable Dayuewan to substantially modernise its operations by transformation and upgrading,’” said Henry Liu, Vice President and General Manager of Honeywell Performance Materials and Technologies Asia Pacific, and Vice President and General Manager of Honeywell UOP in China. “This combination of technologies are designed as an integrated operating block to maximise product yields, but with lower capital and operating expense than standard configurations.”

The Uniflex MC technology enables a plant to convert more than 97% of its vacuum residue into lighter, more valuable petrochemical products. The process uses MicroCat^TM catalysts, produced on site, to stabilise thermally cracked hydrocarbons into stable light oil products. It produces fuels and feedstocks for downstream petrochemicals manufacturing, both of which can improve plant’s profit margins.

The Honeywell UOP PSA technology efficiently recovers and purifies hydrogen perform catalytic processes that transform crude oil into light oil products and other petrochemical products. Honeywell UOP has installed more than 1100 Polybed PSA units in more than 70 countries.

Since its establishment in December 2016, Dayuewan has been committed to the concept of green, energy-saving and high-efficiency technologies. It has established a modern petrochemical complex with advanced technologies, equipment and recyclable resources and which integrates production, processing, storage, and terminals.
