Name and Location
Boiler emissions abatement (BEA) plant project, Gauteng, South Africa.
Client
Impala Platinum.
Project Description
The project will involve the installation of an integrated plant at Impala’s refinery complex in Springs, Gauteng. It will efficiently and effectively remove pollutants, such as fly ash particulate, sulphur dioxide and nitrogen oxides, from the boiler flue gas, exceeding the requirements of South Africa’s National Environmental Management: Air Quality Act.
The plant is being designed to provide the most economical solution, while maintaining a low degree of technical risk and making optimal use of scarce resources. Complying with Occupational Health and Safety Act, ISO 9000 and ISO 14000, the plant will reduce particulate matter from the boiler flue gas to less than 25 mg/Nm3, sulphur dioxide (SO2) to less than 200 mg/Nm3 and nitrogen oxide (NOx) to less than 150 mg/Nm3. It will also improve existing boiler heat recovery and boiler feed water systems.
In addition, the plant will produce a minimal amount of waste residual, reducing the environmental impacts from waste handling or disposal.
The major components of the BEA plant include an ELEX catalytic gas cleaning system for removal of NOx gases; three economisers for boiler heat recovery and a new boiler feed water system; a Simatek dry flue gas cleaning system, with four Simatek pulse jet bagfilter modules, a lime reagent storage and dosing system for SO2 and PM removal; and a dry particulate waste pneumatic transfer system.
