Technology Driven and Equipment Oriented Units of Alumina Refinery

Hi Friends,

We have studied so far in detail the design and operating features of Alumina refinery. We have also made ourselves well acquainted with the technological advancements as well as modifications and improvements in major equipment considered for efficient operation of Alumina refinery.

In present post, we will discuss the highlights of our previous posts with more specific to technology and equipment oriented unit operations and unit processes of Alumina refinery. The process sequence of various units of Alumina refinery has been shown below-

As such, unit operations are complicated and unit processes of Alumina refinery are complex in nature because of inter dependence on the major operating and process parameters of upstream and downstream units as even minor deviations / fluctuations in process control parameters abruptly affects the plant efficiency figures. Over a period of time, lots of developments in process technology as well as improvements and modifications in equipment have occurred which has resulted in drastic reduction in overall energy consumption and raw material consumption as well ultimately improving the profitability of the plant. 

Based on our studies and experience in the field, we have clearly depicted in above diagram, the technology driven and equipment oriented process and operating areas of Alumina refinery. Selection of right technology and right equipment matching with optimized process and operational parameters will result in improved efficiency figures thereby lower capex and opex of Alumina refinery. 

Please put your views / suggestions / remarks / comments, if any.

Regards.
