CONTROL SYSTEMS + AUTOMATION

ROUND UP

Flagship control system for mine in Namibia

Rockwell Automation has been selected as the supplier and integra- tor of the automation control system for Swakop Uranium’s Husab mine near Swakopmund in Namibia.The Rockwell Automation control systemwill enable control of the complete array of automated leach- ing plant processes through a 5 500 I/O architecture.The planned 18 month integration phase began in July 2014. The Rockwell Automation portion of the contract includes the supply and integration of the control and visualisation hardware and software. Rockwell Automation was able to guarantee specific timeframes that were in line with strict project delivery requirements. Its solution follows a standardised approach, which enables a high degree of implementation certainty and reliability through strong domain expertise and one of the largest teams of control system engi- neers in the region.The Husab Project’s plant areas will be controlled by ControlLogix controllers via a complete Ethernet/IP network layer. Through the Rockwell Automation fully-integrated PlantPAx process

automation system, which encompasses the entire control topology from the visualisation layer down to the device layer, the complete set of processes constituting the leaching plant will be controlled.This

includes everything from the conveyor feed into the leaching plant, the crushing of pulverised rock, and the calcining of U3O8 through agitated acid leach. Enquiries: Michelle Junius. Tel. 011 654 9700 or emailmjunius@ra.rockwell.com

Control system order for oil refinery in China

Yokogawa China, has received an order from Petro ChinaYunnan Petrochemical Co to deliver control systems for an oil refinery that is being built in China’sYunnan Province. With an annual output of 10 million tons, this will be one of the largest refineries in southwestern China. As most of China’s oil refineries are lo- cated along the country’s east coast, the high cost of transporting oil products to inland regions is a concern. As a national priority measure, a pipeline is being constructed that will transport 23 million tons of crude oil annually fromMyanmar to China.To receive and process the oil from this pipeline, mul- tiple oil refineries (total annual capacity: 20

ies in South Western China, and it will start operation in 2015. Enquiries: Christie Cronje.Tel. 011 831 6300 or email Christie.cronje@za.yokogawa.com

million tons) and an ethylene plant (annual capacity: one million tons) will be built in Yunnan Province, with work on these facili- ties to be completed by 2020.The refined oil products and ethylene from these plants

will be sent on to other plants in Yunnan Province and other inland regions, significantly reducing transportation costs. In the first stage of this project, Petro China Yunnan Petrochemi- cal is constructing an oil refinery (annual capacity: 10 million tons) in the Anning Industrial Park, 40 kilometres fromKunming City.This will be one of the largest refiner-
