Synthetic Compressor Oils for Production of Polyethylene

The possibility of manufacturing synthetic compressor oils for production of polyethylene is demonstrated. The propane–propylene fraction of catalytic gases or propylene from the EP–300 plant can be used as feedstock. After hydrogenation, fractions that totally satisfy the requirements for NKM–40 and NKM–200 mineral oils are separated from the oligomers. Wide–scale tests of these oils in compressors in the first and second levels of existing production of high-pressure polyethylene confirmed the possibility of using them to totally replace mineral oils.
