Mobile mechanical vapor recompression evaporator

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 that does not evaporate;
• 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 that does not evaporate;
• 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 at least one 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 or compositions.
