Shanghai Coking & Chemical is the largest syngas producer in the Shanghai area, supporting many industrial consumers.
Shanghai Coking & Chemical Corporation is installing Emerson’s PlantWeb digital plant architecture with Foundation Fieldbus technology for the $375 million expansion of the coal gasification plant in Shanghai. The project has doubled the plant’s output of methanol and carbon monoxide to help meet the rapidly increasing need for methanol in the region. The expanded plant began operation in June 2008.

The plant converts coal to synthesized gas, methanol, and carbon monoxide in huge amounts. Each hour, the plant expansion project produces 11,618 m3of synthesized gas, 22,000 m3of carbon monoxide, and 56 tons of methanol. The synthesized gas is supplied to customers in Shanghai Chemical Industry Park, while the methanol and carbon monoxide are used as chemical intermediates for acetic acid.

“We selected Emerson’s PlantWeb architecture because it provides a simple digital architecture that can be easily configured to meet the complex requirements of our process,” says Guanghua Li, chief engineer for Shanghai Coking and Chemical. “The improved predictive capabilities and streamlined communications provided by PlantWeb technology will help us meet our high availability targets for the expanded plant.”

In addition to installing PlantWeb, Emerson’s contract includes project management, system integration, configuration, commissioning, startup, and maintenance services.they interrupt production.


Shanghai Coking & Chemical is the largest producer of city coal gas in the Shanghai area, providing 50% of Shanghai’s gas demand with a current daily output of 3.2 million m3. The company’s main annual byproduct output includes 1.5 million tons of coke, 800,000 tons of methanol, and 360,000 tons of carbon monoxide.
