3. Methodology for Project

7. Brainstorming for cause identification
.Spinbath loss through spinning machine due to trough overflow
.Dripping not running continuously
.Tow washing not proper
.Spinbath loss through bottom tank
.Spinbath loss with tow carry over
.Acid loss through MSFE vapour condensate

8. Brainstorming for cause identification
.Spinbath loss through MSFE heaters because of R/L heater failure
.Spinbath loss through MSFE heaters because of graphite heater failure
.Spinbath loss through MSFE heaters because of Pipe failure
.Magma Tank over flow
.Mother liquor tank overflow
.Salt loss through melting pan overflow

9. Brainstorming for cause identification
. .Salt loss through settler over flow
.Salt loss through drum dryer exit end emission
.Salt loss through scrubber air
.Salt loss through anhydrous circulation pumps gland packings
.Salt loss through scrubber water
.Salt loss through anhydrous pipes leakage
.Salt loss though wet salt production
.Salt loss through grit salt production

10. Brainstorming for cause identification
. .Spinbath loss through mixing condenser water carry over
