Project design containing graphics and illustrations:
The Bayer process block flow diagram:
HAZOP:
Risk probability is high at two main designed equipment:
Digester
Kiln
Main sources of risk:
High pH.
High temperature.
Conclusions:
1- The capacity of the plant is 5 Mton/y (two production lines).
2- The main units are digester (2 reactors per line), clarifier( one settling tank per line), precipitator (22 crystallizers per line) and rotary kiln (one kiln per line) were designed.
