Portfolio
Automation of Activated Carbon Dosing System
2010
Prior to the installation of an automatic activated carbon dosing system, the activated carbon was added manually into the process. The manual addition of activated carbon into the process resulted in problems such as human error and inconsistencies with regard to its dosing and therefore a need arose to automate the system.
The project had the following scope of work: (1) Design, manufacture and supply of activated carbon dosing tank, complete with: (a) a metering system to quantify activated carbon added to process (b) necessary instrumentation
(2) Installation of an automatic activated carbon dosing system and (3) Commissioning of an automatic activated carbon dosing system.
Upgrade of Surface Condenser for Ammonium Sulphate Plant Crystalliser (D-Unit)
2011
Following the successful upgrade of the Ammonium Sulphate Plant crystalliser (C-Unit), the surface condenser for the Ammonium Sulphate Plant crystalliser (D-Unit) had to be upgraded as well in order to return plant operation to design capacity. The project had the following scope: (1) Manufacture and supply one new surface condenser for D-unit and (2) Installation and commissioning of new surface condenser for D-unit.
Upgrade of Surface Condenser for Ammonium Sulphate Plant Crystalliser (C-Unit)
2009
The purpose of the project was to upgrade the surface condenser for the Ammonium Sulphate plant crystalliser (C-unit) in order to return plant operation to design capacity. The project scope was as follows: (1) Manufacture and supply one new surface condenser for C-unit (2) Installation and commissioning of new surface condenser for C-unit.
Decoupling of Cobalt Mixed Double Salt Separation Circuit
2007
The aim of the project was to modify the mixed double salts circuit in Cobalt Plant (BMR Nickel, Impala Platinum Ltd, Springs) in order to have three of the four cooling towers online simultaneously. This was done in order to (1) To improve stripping of nickel and cobalt through mixed double salts circuit (2) To increase flexibility of operating the mixed double salts circuit.
