Abstract
An NGL recovery facility utilizing a single, closed-loop mixed refrigerant cycle for recovering a substantial portion of the C2 and heavier or C3 and heavier NGL components from the incoming gas stream. Less severe operating conditions, including a warmer refrigerant temperature and a lower feed gas pressure, contribute to a more economical and efficient NGL recovery system.
