Abstract

Methods and systems for measuring the concentration of a light gas in a main flow stream are disclosed herein. The methods include calculating a control parameter as a function of the concentration of the light gas in the main flow stream; dividing a portion of the main flow stream to produce a feed stream; and separating the feed stream by selective permeation across a semi-permeable membrane to produce a permeate stream enriched in the light gas and a retentate depleted in the light gas. A ratio of the flow rate of the feed stream to the flow rate of the main flow stream may be increased or decreased according to the control parameter. In addition, an area of the semi-permeable membrane may be increased or decreased according to the control parameter.
