Chevron Refinery upgrade by sera DoseTech
March 2012
News
sera DoseTech South Africa was recently selected as the chemical dosing pump supplier for Cape Town’s Chevron Refinery demineralisation boiler feed water plant upgrade.
The demineralisation process requires raw water to flow over resin in a cation and anion column. The minerals are attracted to the resin stripping them from the water ensuring that the water entering the boiler tubes is mineral free. This is important to prevent scaling and corrosion of the boiler tubes which will result in poor heat transfer and tube failure.
In the process the demineralisation resin needs to be regenerated (the minerals need to be removed from the resin). This process is carried out by dosing 98% sulphuric acid into a water stream, the diluted acid is then pumped through the resin, stripping the minerals and cleaning the resin. Once the resin is clean, caustic soda is dosed into the water stream, the diluted caustic is then pumped through the resin to rinse and neutralise the acid water, before returning the demineralisation plant back into service.
The boiler feed water reliability is critical to the refinery’s production reliability. With reliability as the key focus, sera dosing pumps were chosen as the preferred dosing pump supplier. The model R410.2-940 ML pump was installed for both chemical applications and the multilayer diaphragm design is perfect for the extremely corrosive sulphuric acid, with the multilayer diaphragm the pump gearbox will be protected should the diaphragm fail.
