Revamp of a distillation column

An existing distillation column used for the separation of an organic solvent mixture needed modernization to allow both capacity increase and product quality improvement. After analysis of the actual situation, ENVIMAC presented a concept based on replacement of the existing sieve trays with high performance random packings type McPac and optimized column internals and changing the operation parameters. The capacity of the column was tripled, thus a parallel line was completely stopped, leading to extra energy savings.
