SELOP® Technology
for SELectivity Optimized Hydrogenations for the petrochemical and refining industries
In 1998, BASF introduced the trademark SELOP® for the commercialization of a broad spectrum of hydrogenation process technologies. As of today, our customers have selected BASF superior performing SELOP® technology for more than 70 hydrogenation units worldwide. In the 1990s, Engelhard Corporation already lincensed hydrogenation technologies under the brand name HPN. After the acquisition of Engelhard by BASF, both technologies have been available from one source. This is a consequence of our firm commitment to focus on our customers’ needs and contribute to their success with innovative and sustainable solutions.
Overview of SELOP® technologies and applications
The SELOP® process technologies are applied for selective hydrogenation, full hydrogenation and/or hydrodesulfurization of many different hydrocarbon streams with applications in the refinery and petrochemical fields. BASF delivers tailor-made designs that minimize CAPEX and OPEX and maximize the return of investment.
