Glycerin Distillation Plant is broadly divided into three main sections viz. de-aeration section, distillation section and bleaching section.
- The de-aeration loop consists of a re-circulation pump and heat exchanger. The pump circulates the crude glycerin to the de-aeration vessel and feeds de-aerated crude glycerin to the distillation column.
- The distillation section is composed of various systems consisting off vaporization system, stripping system, rectification system, pump around system and scrubbing system.
- Bleaching section composed of two fixed beds of activated carbon. Distilled glycerin is cooled to bleaching temperature and then passed through the bleachers.
The bleached glycerin is filtered and then finally cooled down to storage temperature before discharging to the battery limits.
