ROUND UP CONTROL SYSTEMS + AUTOMATION
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.

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
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-
ies in South Western China, and it will start
operation in 2015.
