HIGH PRECISION DETECTION OF THE VOLUME PROPORTION OF A COMPONENT IN A MULTICOMPONENT FLUID

摘要

The method involves partly separating a component from multi-component fluid e.g. damp gas (F). Two reference flow rates (M1, M2) are selected from a flow rate (m1) of the multi-component fluid, a flow rate (m2) of residue fluids (T) resulting from separation of the component and a flow rate (m3) of separation fluid (K). Mass portion of the component is determined from the selected reference flow rates by considering a non-separated residue portion (m-w2) of the component in the residue fluid. A foreign portion (md3) of a remaining component (D) of the multi-component fluid is considered. The remaining component is carbon monoxide, carbon dioxide, nitrogen and hydrogen. An independent claim is also included for a device for determining a mass portion of a component of multi-component fluid.
