Reflux - WikipediaThe geometry of the still also plays a role in determining how much reflux occurs. In a pot still, if the tube leading from the boiler to the condenser, the lyne arm, is angled upward, more liquid will have a chance to condense and flow back into the boiler leading to increased reflux. Typical results can increase production as high as 50% over ...
What is Reflux Condenser? - Definition from PetropediaA Reflux Condenser is a machine that uses a distillation technique known as reflux to liquefy the vapor that returns to its condensate form to the system from which it originated. In this technique, large scale distillation columns as well as fractionators are utilized.
What Are the Functions of Condenser Water Pumps? | eHowUsually condenser pumps return water to the HVAC system, but there are occasions where this is not desirable. For example, there may be only a small amount of condensate--enough to be a problem but not enough that its recovery was really needed by the system--and it would be better for the system if it were simply expelled.

It will pump water 11 meters high, lift water 8 meters and has a maximum flow rate of 2200 litres per hour. I do not use a bypass, I just pressurise the entire system, and fit flow control valves to the output line of each condenser in ...
How to: Water Flow in Condensers | Hobby ChemistryFor some fun, you can add dye to the water and have some colorful coolant for your condenser… Disadvantages. My pump was dirt cheap and it works well. However, some very cheap pumps may not have enough power to pump water into a condenser. Try to buy one in a store that allows you to change the item if it doesn't work properly. Final Notes
Cooling Tower and Condenser Water Design Part 1: The ...It's best to begin by thinking about the chilled water system in 3 parts or stages: (1) the condenser water side (2) the evaporator side and (3) the load side. (See Figure 1) Each of these stages overlaps via some form of heat transfer, ultimately taking the heat from the building and releasing it to the atmosphere using sequential media.
Reflux System in the Amine Plant | Oil & Gas Industry ...Reflux System in the Amine Plant. Reflux is a process where a fluid is removed from a vessel, condensed and returned to the vessel to enhance the process. The reflux system consists of reflux condenser, accumulator and pump.
Water flow in condenser - Chemistry Stack ExchangeOf course this doesn't work well for the Liebig condenser you pictured, but you generally wouldn't use this kind of condenser for reflux anyway. The most common condenser for reflux is the Dimroth condenser which can be used for countercurrent exchange without any problems as the entry and exit of the water are both at the top of the condenser.
Refluxing a Reaction - Dixie State Universitysolvent rises into inside column of the reflux condenser, it is cooled by the jacket of water on the outside and condenses. It then falls back into the solution. In this way, you can maintain a reaction at the boiling point of the solvent indefinitely, as long as the water in the reflux condenser is cool enough to condense all of the vapor.
In simple distillation, how does a condenser work? - QuoraIn simple distillation the condenser turns steam back into water. It does this by cooling steam to below 100°C when it becomes liquid water again. In a lab setting you will see a downward facing glass tube, maybe with spirals of glass maybe with i...
How Does a Condensate Pump Work? | HunkerIn the pump, an impeller is located at the bottom of the condensation pump. This is the mechanism that does the pumping. The motor attaches to the impeller with a metal bar and is located near the top of the tank or someplace out of the water.
Understanding Process Vacuum Condensers - GrahamUnderstanding Process Vacuum Condensers Process vacuum condensers are an integral part of a vacuum system So often, a process vacuum condenser is considered stand-alone equipment, with little consideration given to how best to integrate it into a vacuum system. Common practice has the vacuum condenser specified as just another heat exchanger.
Pumps for recirculating water - Home DistillerThe pump recirculates the water, the output (hot side) of the condenser dumps in the top of the pipe and runs down over hardware cloth as the air from the fan blows up through it. Result, cooled cooling water. I was going to do it, but then I realized the 10,000 gallon pool sitting right there on the patio would work just fine.
Gulf Power Commercial Library - Apogee InteractiveThe calculations used to make these installation cost and energy savings estimates are consistent with FPSC rules and good engineering practices.
Take a Different Look at Centrifugal Pumps | Chemical ProcessingIn Figure 1, the reflux control valve is a hand-operated control valve (HCV). The reflux system doesn't include an automated pressure drop. It essentially has a fixed system curve. This brings us to thinking about the pump operation: pump flow stems from back-pressure on the pump. Now, let's consider the tower pressure-control system.
What causes the condenser if the water pump fails to work ...The water pump is a part of your vehicle with an important role in the engine's cooling system. The job of the water pump is to cool down the engine with coolant, which in turn assists in making sure the engine does not overheat.
How Does an Air Cooled Condenser Work? | SPG Dry CoolingHow Does an Air Cooled Condenser Work? An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC.
Condenser (laboratory) - WikipediaThe Allihn condenser or "bulb condenser" or simply "reflux condenser" is named after Felix Richard Allihn (1854–1915). The Allihn condenser consists of a long glass tube with a water jacket. A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense.
