Distillation columns are essential items used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities. Fractionating columns are used in small scale laboratory distillations as well as in large scale industrial distillations.

We manufacture carbon steel glass lined columns in flanged sections used in several types of applications for use in aggressive acid conditions.
