Dealing with dust in Deyang

Published by , Editor

Tang Yong and Li Qiang, Southwest Cement Group, and Adam Feng, W. L. Gore & Associates, share how a dust collection system upgrade helped improve environmental results, reduce operating costs and increase productivity for the Lisen Cement Plant in Deyang, China.

China’s increasingly robust environmental protection policies represent a strategic commitment to reducing their national environmental impact. Achieving these regulatory targets is a top priority for virtually every manufacturing enterprise. For the cement industry, successful compliance will require upgrades to production facilities that will reduce both energy consumption and emissions, while also achieving higher operating efficiencies.

The Southwest Cement Group, one of China’s largest producers, has been actively upgrading to energy-saving and emission-reducing equipment across its subsidiaries.

One subsidiary – the Lisen Cement plant – recently partnered with W. L. Gore & Associates to dramatically transform its dust collection system. The resulting reduction in emissions, energy consumption and operating costs clearly justified the investment in this upgrade.

Problems and solutions: The kiln mill collection system

Within a cement production line, the dust collection system is the primary piece of environmental protection equipment. As such, its efficient and stable operation is crucial. The Lisen plant, a 3800 tpd clinker production line, was experiencing a number of issues with its ageing dust collection system which made the upgrade advisable. The kiln mill dust collector had serious corrosion issues, unacceptably high dust emissions, and large operating pressure differentials that contributed to excessive power consumption.

A team from Gore, led by Adam Feng, Application Engineer, worked closely with key personnel from both the Lisen plant and the Southwest Cement Group to document the issues and define solutions that would meet key environmental and operational objectives. This had to include identifying critical timelines to ensure production output would not be negatively affected.
