Shanghai Plant Chooses Emerson To Digitally Automate Expansion


Apr 07, 2009

Shanghai Coking & Chemical Corp. and Emerson Process Management announced that Emerson had been selected to provide its 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. The expansion project produces hourly 11,618 cubic meters of synthesized gas, 22,000 cubic meters of 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 a chemical intermediate 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,” said Guanghua Li, chief engineer for Shanghai Coking and Chemical Corp. “The improved predictive capabilities and streamlined communications provided by PlantWeb technology will help us meet our high availability targets for the expanded plant. Emerson’s extensive experience in large project management was another factor in the selection process. We have already been very impressed with Emerson’s strong local engineering and support capability.”

In addition to installing PlantWeb, Emerson’s contract includes project management, system integration, configuration, commission and startup, and maintenance services.  Emerson’s PlantWeb digital architecture delivers operational excellence by networking thousands of smart devices throughout plants, enabling optimum control, while continuously gathering diagnostics data that is used for asset optimization, including predictive maintenance.  Plant personnel use the data to correct potential equipment and process problems before they interrupt production.
