Our technology

Separate closely related hydrocarbons by molecular size

High-precision molecular sieving separates closely related hydrocarbons by molecular size. Precisely defined pores can distinguish molecules that differ by fractions of an ångström, while a pressure difference drives continuous separation. The high precision allows separation of olefins from paraffins, olefins from olefins, or paraffins from paraffins. The resulting streams can then be routed towards recovery, reuse or further processing.

Designed to integrate. Built around your plant.

Our modular, containerised systems are configured around your stream, available space and existing equipment. Integration planning covers the required connections, utilities and stream conditioning so the separation step can fit around the wider process.
