Project Scope
Provided all engineering for a system that met the required evaporation
and concentration. Provided all equipment required for a functional
system. This included evaporators, heat exchangers, tanks, pumps,
valves, instrumentation, DCS specifications and piping to achieve
the required result.
Results
The project was engineered and supplied in 9 months. After installation,
the equipment was smoothly commissioned in a 6 week period and was
completely accepted after the commissioning stage.

Process Flow
Liquor is concentrated in Effect 4 and then directed to the alcohol
plant for neutralization, fermentation and distillation. The liquor
is returned from the fermentation operation to Effect 3.and counterflows
from effect to effect where it is finally discharged from the Effect
1 at 50% total solids. One extra body and associated piping and valves
is provided to allow each body to be isolated and washed one at a
time while maintaining the required production rate and incurring
no downtime during the changeovers.
