ABB announced that it has received a R32-million process automation contract from cement company Alpha South Africa for the upgrade of Alpha’s kiln 3 at Dudfield. The aim is to use the latest technology to increase production of the kiln. The new filters will help reduce stack emissions to well below internationally applied standards.
The order includes the process automation hardware and software design for the entire plant, automation, and field instrumentation, supply of low and medium voltage switchgear, installation and cabling. The company will replace the existing AC450 DCS system at the site with an AC800M and operator information technology system, supply five 525VAC motor control centres (MCC), a 6,6kV panel switchboard as well as two distribution transformers and one converter transformer.
Two water-cooled ACS 1000 as well as five ACS600 variable speed drives will be sourced from ABB in Denmark and a 400kW AC induction motor will come from Finland. The new equipment will be installed during Alpha’s shutdown period in August to November this year.
