Humidifying control system for eco-friendly cement plant

July 2005 System Integration & Control Systems Design

Designs Unique, a Johannesburg-based company specialising in data acquisition projects, was recently commissioned to install a laboratory humidifying system at the Lafarge Bamburi Cement plant in Mombasa, Kenya. The correct and efficient humidification of such laboratories and test facilities forms an integral part of the required processes.

Following the development of a sophisticated software package for the PC-based display, monitoring and logging of critical data in laboratories, chiefly for the cement and concrete industries, Designs Unique designed and produced the award-winning DTH-Sense-Aire temperature and humidity meter/transmitter.

This accurate instrument, together with the monitoring software, has already been installed at several plants including CSIR Miningtek, Holcim, Lafarge PAD, PPC, the Cement and Concrete Institute in South Africa, Circle Cement in Zimbabwe and Johannesburg Water.

The Lafarge Bamburi Cement plant is one of the early operations in Africa to undergo rehabilitation of the environment. As a result of limestone quarrying activities, which had been going on since 1954, huge tracts of land had been left bare and scarred.

To restore the land, Dr Rene Haller, an agronomist, was invited in 1971 to rehabilitate the quarries. The goal was not only to remove the eyesore, but also to create a more productive ecosystem that would also be a safe haven for the protection of endangered coastal species of plants and animals.

Today, one can walk around Haller Park and not even realise one is at a cement plant. Lafarge Bamburi is one of Kenya's largest manufacturing companies and the largest cement producer in East Africa, producing 1,3 million tons of cement annually.
