As a wiped film evaporator, molecular distillation or a molecular still (also known as short path evaporation or SPD) operates with a plug flow throughput of feed material (first in/first out) and a very short residence time while operating under a vacuum. The higher vacuum possible in a molecular still down to micron levels of vacuum compared
Cornmeal is a stable and inexpensive (5-10 cents per pound) selective absorbent of water from ethanol/water vapor. Laboratory results show that the adsorption of water from ethanol by cornmeal gives an anhydrous (water-free) product, starting from 190 proof vapors from a distillation column.
The results from Example 1 are given as a red X in the figures. The difference between molecular weight of naphtha from Eq (1) and (3) is 0.2 %. Example 2: Molecular weight of a light gas oil from a distillation curve. D86 used to distille a gas oil sample showes: 10vol% recovered at 255 °C 30vol% recovered at 280 °C 50vol% recovered at 303 °C
