Invensys Process Systems Involved in New Alumina Plant
Invensys Process Systems (Foxboro, MA, USA) has been chosen to implement I/A Series digital automation from Foxboro to control processes throughout the new Luoyang Xiangjiang Wanji Aluminium Ltd alumina plant being built in Luoyang Xinan county in the Henan province of China.
In addition, Invensys Process Systems China will provide hardware integration services for the 400,000 tons per year grassroots bauxite refining facility, which will use the Bayer Process technology to make the alumina feedstock.
Automation systems at the new plant will employ I/A Series redundant control processors at seven control nodes serving processes throughout the facility. The control nodes are for raw materials processing, solvent extraction, settling, separation, product filtration, evaporation and baking. The control processors are connected with more than 5,200 I/O points, representing a wide variety of sensors, devices and signal interfaces.
The control nodes are interconnected with a redundant network built around a control and dispatching centre equipped with 15 sets of operator workstations and seven sets of engineering and operational workstations. The centralised facility provides real time data and full graphics of the plant automation network, supporting the plant's production monitoring and optimisation applications.
The Luoyang Xiangjiang Wanji project is part of a Chinese government initiative to increase the domestically produced supply of alumina through the consolidation and construction of larger and more efficient processing plants.
