· Cryogenic air separation units (ASUs) then take the air through another cycle of treatment to extract gases of a higher purity of volumes in excess of 4,000 t/d per ASU. This involves air liquefaction and distillation. The boiling points of pure gases are 183 o C for oxygen and 196 o C for nitrogen at atmospheric pressure.
· Air separation techniques 1. Air separation techniques 2. air separation • 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.
1 Air Separation of Cryogenic Gases: Current Technologies. An Air Separation Unit (ASU), is a type of technology that separates air into its main constituents. The most abundant components are Nitrogen, followed by oxygen and then argon, as well as other inert gases in small amounts. The compositions are summarised in table 1 below.
Air separation plants separate atmospheric air into its primary constituents, which are approximately 78% nitrogen, 21% oxygen, % Argon and a handful of rare inert gases (xenon, neon, hydrogen, helium, krypton and carbon dioxide). These facilities produce air separation gases or industrial gases, including oxygen and nitrogen.
The membrane gas separation equipment typically pumps gas into the membrane module and the targeted gases are separated based on difference in diffusivity and solubility. For example, oxygen will be separated from the ambient air and collected at the upstream side, and nitrogen at the downstream side.

We focus on R D, manufacturing and installation of all kinds of complete sets of air separation equipment, and provide comprehensive services of gas investment, EPC engineering, equipment operation management and bioenergy. We have the ability to design and produce more than 30 sets of large and mediumsized air separation equipment ...
Separation with sorbents/solvents Solvents Amine scrubbing technology was established over 60 years ago in the oil and chemical industries, for removal of hydrogen sulphide and CO2 from gas streams Commercially, it is the most well established of the techniques available for CO2 capture although practical experience is mainly in gas streams which
Although oxygen is the main product targeted in air separation for gasifiion processes, several byproducts of air separation can be useful and valuable. These are discussed below. Nitrogen Nitrogen (N 2) has many appliions, but, specific to gasifiion, nitrogen .
Large Air Separation Unit. Used in a wide variety of fields, large air separation units (ASU) produce high purity oxygen, nitrogen, argon and rare gases through a combination of adsorption purifiion, cryogenic distillation and internal compression of high pressure products.
· When industrially separating gas mixtures that can absorb gas, the adsorption operation has significant advantages. At present, due to the development of adsorption technology and the emergence of new adsorbents, the adsorption process is used in cryogenic air separation units and atmospheric pressure swing adsorption air to produce oxygen and produce The appliion of .
Built to the highest standards of reliability and efficiency, the ASPEN is a mediumsized cryogenic air separation plant. The Aspen Series is designed to produce liquid nitrogen, oxygen and, as an option, liquid argon. Plant capacities range from 15 to 35 metric tons per day of combined liquid products with an optional high purity nitrogen gas ...
· The gases in air can be separated from one another through a process known as the fractional distillation of liquid air. This is a process that converts air into a liquid form and then allows it to be portioned out into layers and separated from one another. Because pure oxygen and nitrogen have a number of appliions, this is a useful technique.
· Grasys is a Leading Developer, Manufacturer and EPC Contractor engaged in air and gas separation across the CIS and Eastern Europe. The key focus areas of research and production company (RP Co.) Grasys: Design and manufacture of air and gas separation equipment (nitrogen and oxygen units and plants), skidmounted compressor stations. Natural ...
Air separation plants use cryogenic air separation technology to bring gas streams to extremely low temperatures, which allows plants to separate various gases by the condensation point. Gas that is cryogenically separated needs to have extremely low levels of water, carbon monoxide, and carbon dioxide in the stream to prevent freezing and blockage.
Air separation plants must satisfy the most stringent requirements. Our solid expertise means we can ensure the processes in your plants are highquality, ... Siemens Oil Gas provides reliable products, systems and solutions throughout the entire oil and gas value adding process.
Air separation plants range from small cogeneration units providing select gases for a facility to larger plants with both bulk and specialty gases. These plants can be supported by a single employee, managed remotely by a regional team, or fully manned around the clock.
Adsorbents for air separation and industrial gas production: improving standards. High purity industrial gases such as O 2, N 2, H 2 and CO are produced in a variety of ways. UOP's adsorbents help improve the economics of these processes due to their high adsorption capacity and selectivity.
