What is the difference between azeotropic and extractive distillation explain with suitable figures and examples?

The main difference between the two is in the process of separating the mixture. Azeotropic distillation forms an azeotrope right after combining the separation solvent. In extractive distillation, a specific separation solvent is used in every mixture that should not form an azeotrope.

What is difference between azeotropic and extractive distillation?

Azeotropic distillation and extractive distillation are two important types of distillation. The difference between azeotropic and extractive distillation is that the formation of an azeotrope is required to separate the components of a mixture whereas, in extractive distillation, no azeotrope formation takes place.

What is the difference between a zoetrope and an azeotrope?

19-13) What is the difference between a zoetrope and an azeotrope? Both Zeotropes and Azeotropes are mixtures of chemicals that are not chemically bonded; however, azeotropes cannot be physically separated by distillation while zeotropes can be physically separated by distillation.

Is R404A a Zeotropic?

R404A is a zeotropic HFC refrigerant blend of R125, R143a and R134a. It is widely used in medium and low temperature refrigeration especially in the supermarket sector and for refrigerated transport. R404A was designed as a replacement for CFC R502 and closely matches its properties.

Is 404A flammable?

R-404A is classified as non-flammable by the U.S. organization ASHRAE. However, if R-404A is pressurized after being mixed with air, there is a possibility that it could become flammable. R-404A must never be mixed with air under any circumstances.

What PPE should technicians always wear when handling refrigerant?

PPE for HVAC and Refrigeration technicians Inner nitrile gloves help to prevent exposure to harmful substances, and outer work gloves protect your hands from injury. Work boots protect your feet from injury when you’re working with sharp tools or heavy objects. Hard hats may be required in some working conditions.

When handling refrigerants technicians should?

When handling Refrigerants, Technicians should? Wear approved eye protection and gloves/ Avoid loose fitting clothes.

What safety equipment must you always wear while working with refrigerants?

Also, careless handling of cylinders can result in sudden releases of refrigerant, which can cause frostbite, skin damage or blindness. To avoid these circumstances, workers should wear safety glasses with side shields or a full-face shield, safety shoes, hard hat, long pants, gloves and a long-sleeved shirt.
