Abstract:
1. A method of blending fluids, comprising: transmitting a first fluid through a first optical cell operable within a first transmission line into a downstream line; transmitting a second fluid through a second optical cell operable within a second transmission line into said downstream line; scanning said first fluid over a broad wavelength range within the near infrared spectrum using a first tunable laser within said first optical cell to determine a property of said first fluid using spectrographic analysis from said first tunable laser; scanning said second fluid over a broad wavelength range within the near infrared spectrum using a second tunable laser within said second optical cell to determine a property of said second fluid using spectrographic analysis from said second tunable laser; determining a property of said first fluid using chemometric analysis of said spectrographic analysis from said first tunable laser and determining a property of said second fluid using chemometric analysis of said spectrographic analysis from said second tunable laser; and altering said transmission of said first fluid through said first transmission line or said second fluid through said second transmission line based on said property of said first fluid and said property of said second fluid, thereby altering a property of a fluid in said downstream line.
