Zhuhai optimisation

Examples of how our team in Zhuhai, China, continuously optimise production.

Here are examples of technological innovation and operational optimization that led to our team in Zhuhai, China, reducing CO2 emissions by 12,000 in 2024 alone. It is thanks to this culture of continuous improvement that the team has been named an ‘Energy Efficiency Leader’ and benchmark enterprise in the PTA industry by the China Petroleum and Chemical Industry Federation for six years in succession. More on Zhuhai efficiency.

Boiler preheater

Boiler preheaters enhance the efficiency of boiler systems by preheating the feedwater before it enters the boiler. By using waste heat from the boiler's exhaust gases, the boiler requires less fuel to reach the desired steam temperature. The preheated feedwater also helps to maintain a more stable boiler operation, which can extend the lifespan of the boiler. By completely redesigning and upgrading the Zhuhai boiler preheater system, CO2 emissions were reduced by nearly 4,000 tons in 2024.

PTA feed exchanger

A feed exchanger in chemical manufacturing is a type of heat exchanger used to transfer heat between the feed stream (the input material) and another process stream. This helps to preheat the feed before it enters a reactor or another processing unit, improving energy efficiency and process performance. Their performance is critical to, in our case, maintaining highly efficient PTA production. In Zhuhai, our team conducted a detailed analysis of the key factors that contribute to the feed exchanger’s performance during routine operation. By using the results to make systematic improvements to its daily operations, the team has been able to optimize performance during its full cycle and reduce CO2 emissions by nearly 3,000 tons.
