Webcompress at high compression ratios with low volumes and compress at low compression ratios with high volumes. These conditions require varying speeds and load … WebNatural Gas Developments The selection of machinery efficiencies has a significant impact on this process comparison. Some literature sets these efficiency values at 100%, assuming an equal basis of com-parison. However, this will lead to a false conclusion: Theo-retically, the N 2 expander cycle would have up to 15% less power than the SMR.
