Mipac takes control in China

Supplier News

MIPAC successfully implemented and commissioned an Emerson Delta V and fieldbus measurement and control system at China’s newest lead smelter, the CYMG IsaSmelt at Qujing, in August this year.

IsaSmelt forms part of a major greenfield plant designed to process 160,000 tonnes of lead concentrate per annum. It is owned by China State, and is a major metals and chemicals business in China.

CYMG and Xstrata Technology selected Mipac to specify the measurement and control equipment and installation requirements. Mipac was also asked to design, configure and commission the Emerson DeltaV control system for the smelter and associated feed system.

“China is one of the world’s fastest growing economies and a large consumer of mineral resources,” said Paul Puusaari, CYMG project director and Mipac director. “This puts great pressure on mineral processing companies to upgrade smelter capacities, increase productivity and efficiency and reduce negative environmental impacts.”

For the project Mipac provided the following services: specification of measurement and control equipment; basic installation design; interface with Chinese engineering group, ENFI; supervision and inspection of field and DCS installation; commissioning of the fieldbus system and field instrumentation; logic and HMI design, configuration, testing and commissioning; hot commissioning, loop tuning and plant stabilisation of smelter controls; provision of Brisbane-based and on-site training for CYMG personnel; and the establishment of remote monitoring facilities to provide control system support for CYMG personnel.

Also in China, prior to the CYMG commissioning, Mipac worked with Xstrata Technology on a significant new copper smelter in Kunming.
