An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.. The most common method for air separation is fractional distillation.Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.
separation unit (ASU) is a process of high energy consumption. There are various technologies that are used for the separation process, the most common is via cryogenic distillation. The cryogenic separation process requires a very tight integration of heat exchangers

Figure 9.9 shows a process flow diagram for HDS. The feed is introduced into a fixed-bed catalytic reactor along with hydrogen and the products are sent to a high-pressure separator to separate H 2 and H 2 S gases from the hydrocarbons.
This illustrative cryogenic air separation flow diagram illustrates (in a generic fashion) many of the important steps in separating air and purifying its primary constituents into nitrogen, oxygen and argon as gas and liquid products. It does not represent any particular plant.
Air Separation into Oxygen, Nitrogen, and Argon Background The purification of various components of air, in particular oxygen, nitrogen, and argon, is an important industrial process. A feasibility study is to be performed to investigate the possibility of producing 1500 metric tons per day of 99.5% oxygen, 5000
Within the separation unit the air is separated via distillation at very low temperatures to take advantage of the boiling point differences of the air components in a process known as rectification. The distillation column can be designed depending on the specific products needed, with the most common design being the double column system with ...

separation is so called because the liquefaction of air occurs at a temperature from approximately -170℃ to -190℃ and the separation process is performed in a thermally-insulated cryogenic system. Fig. 1 depicts the process flow of the cryogenic separation system generally used. Most air-separation units
A typical process flow diagram (PFD) of such a vacuum distillation column is presented. Light vacuum gas Oil is sent to a hydrotreater and then to a 'catalytic cracking' unit to obtain smaller chain hydrocarbons. Heavy vacuum gas oil is also sent for cracking using hydrogen in a 'hydrocracking unit' to produce smaller chain hydrocarbons.
Separation processes are based on the theory of vapor-liquid equilibrium. This theory states that streams leaving a stage in a separation process are in equilibrium with one another. The idea of equilibrium revolves around the idea that when there is vapor and liquid in contact with one another they are in constantly vaporizing and condensing.
Microfiltration (MF) (see diagram above) is a membrane separation process similar to UF but with even larger membrane pore size allowing particles in the range of 0.2 to 2 micrometers to pass through. The pressure used is generally lower than that of UF process.
