Sulzer Chemtech is providing process engineering and key equipment for the expansion of Dongsuh Indonesia (DSI) naphthalene downstream sector, said Process-worldwide.
The delivery of an advanced separation unit to DSI’s plant in Serang, Indonesia, will enable the production of high purity naphthalene that can be used for applications with stringent quality requirements.
DSI’s facility in Serang processes naphthalene from coal tar to deliver the valuable chemicals. To this end, the plant has been producing naphthalene related products. In order to increase the purity level of its raw materials and end products as well as serving the broader downstream sector, the company selected Sulzer Chemtech’s proven falling film crystallization technology.
Prior to the delivery of the purification unit, Sulzer Chemtech completed extensive feasibility and pilot testing ahead of its basic engineering package. This helped ensure DSI to produce different concentrations, including levels of up to 99.9 wt % at an overall production capacity of 7’000 metric tons per annum.
Song Ho Kim, President of DSI, says: “We are extremely happy with the collaboration established with Sulzer Chemtech. Their solution for crystallizing naphthalene is a leader in the market, so when looking at advancing our offering, we were confident we should invest in this technology. The flexibility of our operations will also be improved, helping us address different market needs while optimizing operational expenses and profitability. We look forward to installing the unit and beginning our first-grade naphthalene operations shortly.”
We remind, Sulzer Chemtech (GTC Technology) and BASF have signed a MoU with the goal of advancing technologies for renewable fuels and chemically recycled plastics that will further expand the partners’ portfolio of sustainable solutions. The companies enter a strategic partnership to reduce the carbon intensity of renewable diesel and sustainable aviation fuel. They will also drive the development of innovative, cost-effective chemical processing solutions to improve the conversion of plastic waste into new plastics.
