China: Technology License Dayuewan Petrochemical to Use Honeywell Technologies for Upgrading Heavy Fuel Oil

Editor: Ahlam Rais

Dayuewan (Zhuhai) Petrochemical Co. will utilise a range of technologies from Honeywell for upgrading heavy fuel oil into higher value petrochemical products at its Guangdong complex in China. Honeywell is also responsible for basic engineering, technology licensing as well technical and start-up services for Dayuewan’s project.

Shanghai/China – Honeywell has recently announced that Dayuewan (Zhuhai) Petrochemical Co., a subsidiary of China Grain Petrochemical Group, will use a range of technologies from Honeywell UOP to upgrade heavy fuel oil into higher value petrochemical products at its complex in the Gaolan Port Economic Zone in Guangdong Province.

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 tonnes-per-year Uniflex MC slurry hydrocracking unit to upgrade bottom-of-the-barrel fuel oil into light oil products. This will be fed to a Unicracking unit to produce naphtha for a CCR Platforming unit. The project also includes three Polybed Pressure Swing Adsorption (PSA) units to supply high-quality hydrogen for the Uniflex process. The PSA units are designed to generate 320,000 cubic meters of hydrogen per hour.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

“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. “These combinations 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 catalyst, 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 a 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.
