Due to sophisticated processing technologies (e. g. catalytic cracking) refineries produce less by-products such as aromatics and paraffin/waxes. For this reason lube oil and paraffin producers look for new, more efficient technologies.
EDL and Sulzer offer the most efficient solution - the free selection of the process (with or without solvent) or a combination of both technologies. Plant modernization and capacity increase are possible without production downtime by combining the processes.
