RAMAN SPECTROMETERS (96,98) ARE EMPLOYED IN A HYDROCARBON PROCESSING PLANT FOR ONLINE MEASUREMENT OF AT LEAST ONE COMPOSITIONAL PROPERTY OF A HYDROCARBON STREAM. THE RAMAN SPECTROMETERS (96,98) CAN BE USED TO CONTROL SEPARATIONS EQUIPMENT, DETERMINE ENERGY CONTENT, AND/OR DETERMINE FLOW RATE. THE RAMAN SPECTROMETERS (96,98) ARE ESPECIALLY ADVANTAGEOUS WHEN EMPLOYED IN A LIQUEFIED NATURAL GAS (LNG) PLANT TO DETERMINE PROPERTIES OF COOLED NATURAL GAS STREAMS. |
