Sulzer has delivered a customised mass transfer solution to PT Enerco RPO Internasional’s grassroots plant for the production of treated distillate aromatic extract (TDAE) in Batam, Indonesia.

The facility features the world’s largest agitated extraction column type KuhniTM (ECR), which has been designed and built by Sulzer. This piece of equipment plays a crucial role in the manufacture of eco-friendly rubber process oils (RPOs) for the tire and rubber sectors.

With a diameter of 2.8 m (9 ft 2 in.) and a height of 34 m (111 ft 6 in.), this is the largest column of its kind and allows PT Enerco RPO International to deliver high volumes of TDAE.

Roy Indra Salim, Commercial Director of Enerco, commented: “A combination of the advanced patented extraction technology from PT Enerco RPO Internasional with Kuhni Agitated Columns from Sulzer Chemtech has been the key success factor for the plant to achieve optimum performance and production efficiency levels with hydrodynamic control capabilities that can contribute to the overall reliability of the plant. The TDAE plant of PT Enerco RPO Internasional in Batam, Indonesia, can be referred to as the largest single TDAE plant in the world and is able to efficiently produce a very high and consistent quality of TDAE to improve the security of supply for green RPO (TDAE) globally.”
