Product Recovery At 75% reflux and 3200 Watts the rate of recovery is approximately.5 gal/hour. At 0% reflux and 2500 watts the rate of recovery is approximately 1.6 gal/hour.

Conclusions At 75% reflux the purity of methane was a much higher quality. If quality is more important then a high reflux percentage is needed. If quantity and timeliness is more important then a low reflux is needed.
