A vapor separator comprising: a generally cylindrical housing configured in a generally horizontal orientation comprising: a first product chamber having a first product passage configured to receive a first product; a second product chamber having a second product passage configured to receive a second product; a vapor chamber positioned between the first product chamber and the second product chamber, the vapor chamber having a vapor passage; a first vapor window located between the first product chamber and the vapor chamber; a second vapor window located between the second product chamber and the vapor chamber; a first sump located in a lower section of the first product chamber and configured to receive a first liquid product of the first product; a second sump located in a lower section of the second product chamber and configured to receive a second liquid product of the second product; wherein: a portion of the first product that evaporates in the first product chamber to produce a first vapor passes through the first vapor window into the vapor chamber, a portion of the second product that evaporates in the second product chamber to produce a second vapor passes through the second vapor window into the vapor chamber; the first vapor and the second vapor combine and is discharged through the vapor passage as a vapor product; and the first sump and second sump within the housing are isolated so first liquid product and second liquid product may be maintained at different concentrations. a generally cylindrical housing configured in a generally horizontal orientation comprising: a first product chamber having a first product passage configured to receive a first product;
