the deviation between 30o and 60o where refluxing (dropout and reverse flow) of particles and heavier liquid occurs in a lower rate well. The area in which gas bubbles may rise through fluid at 4 to 7 times that in a vertical well.

n: a device that uses a solvent to reflux, or flow back over, a sample to clean it. Such a device extracts oil or salt-laden water efficiently without harming the core samples.

n: separation of a hydrocarbon fluid mixture into components by fractionation, wherein the reflux condenser is operated at temperatures requiring refrigeration. See pod (Podbielniak) analysis.

n: in the distillation process, that part of the condensed overhead stream that is returned to the fractionating column as a source of cooling. v: in distillation extraction of fluids from a core, to use a solvent to flow over a core sample a second time to clean it.

n: a length of tubing or pipe bent to assume a coiled shape and through which a fluid cooler than the fluid outside the coil is circulated. The cooler fluid is used to cool the warmer fluid. Cooling causes vapors to condense to liquid.

n: a device on which reflux condenses in the distillation process. See reflux.

n: a relative measurement of the volume of reflux in the distillation process. The ratio is commonly expressed as the quantity of reflux divided by the quantity of net overhead product.
