Abstract
A method for monitoring a chromatograph used to control production of a chemical product. The method involves sampling a chemical mixture of chemical components used during the production to form the chemical product, measuring the composition of the sample with a chromatograph and adjusting the amount of the chemical components based on the measured composition. The method also involves measuring actual parameters of the sample with at least one gauge, determining expected parameters of the sample based on the measured composition and the measured actual parameters using an equation-of-state, and detecting a fault in the chromatograph by comparing the expected parameters with the actual parameters.
