CONTINUOUS MEASUREMENT OF AMINE LOADING IN GAS PROCESSING PLANTS USING RAMAN SPECTROSCOPY

摘要

The present invention provides asystem and a method for continuous measurementof acid gas concentration or amine loading in abasic solution using Raman spectroscopy. Thesystem comprises a sampler for periodically obtaininga sample of one or both of a lean or a richstream basic solution; a Raman spectrometer toobtain a Raman spectrum from one or both ofsaid solutions; at least a processor programmedto: compare a spectral change in the measuredRaman spectrum from a baseline or a control Ramanspectrum; correlate the spectral change withan acid gas concentration or basic solution orboth; and determine if a change to a regenerationparameter is necessary; and if so, provide controlinformation to an actuator to implement thechange.
