Methods and extraction units employing vapor draw compositional analysis

摘要

Embodiments of extraction unit and an analysis method are provided. In one embodiment, the analysis method includes the steps of providing a feed stream and a species-selective solvent to the distillation column, drawing a vapor sample from the distillation column, condensing the vapor sample, and analyzing at least a portion of the condensed vapor sample.

主权项

1. An extraction unit for separating a feed stream utilizing a species-selective solvent, the extraction unit comprising:
a distillation column configured to receive the feed stream and the species-selective solvent; a vapor draw fluidly coupled to the distillation column and configured to draw vapor samples therefrom; a condenser configured to condense the vapor samples from the vapor draw to form condensed vapor samples; a separator configured to separate each of the condensed vapor samples into a first liquid phase and a second liquid phase; and an analyzer system fluidly coupled to the separator and comprising an analyzer configured to measure the presence of at least one component within the first liquid phase, the second liquid phase or both.
