Systems and methods for real-time spectrophotometric quantification of crude oil

A system for real-time quantification of crude oil in an effluent from a coreflooding apparatus, the system comprising:

• a coreflooding apparatus;
• a mixing apparatus in fluid communication with the coreflooding apparatus via an effluent line and with a solvent delivery unit via a solvent line;
• an in-line phase separator in fluid communication with the mixing apparatus via a mixed stream delivery line;
• a continuous flow analyzer in fluid communication with the phase separator via an oil-phase line and configured to receive a stream containing the solvent and crude oil via an oil-phase line and to transmit a plurality of absorption values to a data analysis engine, the continuous flow analyzer being a member of the group consisting of a continuous flow ultraviolet fluorescence analyzer, a continuous flow fluorescence analyzer, a and a continuous flow ultraviolet/visible spectrophotometer;
• and
• the data analysis engine including a non-transitory storage medium for storing executable program code, which when executed by a processor, causes the processor to quantify crude oil in an effluent from the coreflooding apparatus in response to receipt of the plurality of absorption values.
