China’s Chengzhi Yongqing to use Honeywell's technology to make plastics


Nanjing Chengzhi Yongqing Energy Technology is set to build its second Methanol-to-Olefins (MTO) process unit in China. 

The new unit will use Honeywell UOP’s MTO technology that converts methanol from coal and other sources into the olefins that serve as essential ingredients for making plastics.

Located in the provincial capital of Nanjing, the new unit will have an annual capacity of 600,000mt, which is nearly double of the Chengzhi’s existing unit capacity that started production in 2013. 

Honeywell UOP Process Technology and Equipment business vice-president and general manager John Gugel said: "Honeywell UOP’s MTO technology is a proven and growing process in China, where more than $100bn is expected to be invested in coal-to-chemicals technology in the next five years.

"This technology has the highest yield of olefins with the lowest consumption of methanol and catalysts."

"This technology has the highest yield of olefins with the lowest consumption of methanol and catalysts, as well as the lowest operating and capital costs of any MTO solution."

MTO produces olefins such as ethylene and propylene, which are mostly used to make plastics, as well as butadiene precursors that are used to make rubber products. These are traditionally procured from crude oil but the advanced MTO Technology enables to derive the components from other feedstocks such as coal and natural gas in the regions that lack crude oil.

Honeywell UOP’s MTO process makes use of specific catalysts in the process to efficiently adjust the ratio of propylene and ethylene enabling users to adjust production according to the demand.

Furthermore, it requires low operating cost and offers better start-up and operational reliability.
