2. Pre – Cooling system :
The pre-cooling system is a highly efficient skid mounted equipment provided with the main purpose of cooling down the air to a temperature of 5 to 8 degrees Celsius and thus to discharge the condensed water.
3. Purifier :
The purifying system is the secondary process unit which is responsible for the removal of moisture, carbon dioxide, hydrocarbons as well as rare gases that are considered to be impurities in the process cycle of air separation. The structure essentially consists of double layered molecular sieves from “Zeochem” (Switzerland) along with alumina which acts as an adsorbent.
The process purifier is vital to the entire process and is greatly responsible for the purity of the final product i.e. Oxygen and Nitrogen in the Air separation Column. It consists of 2 skid mounted molecular sieve regeneration batteries that work on shifts and switch alternatively either manually or through a PLC control (optional).
4. Air separator Unit :
The Key to the entire Air separation Process lies within the Air Separation Unit. Here, the mixture of Oxygen and Nitrogen is separated by virtue of the difference in their liquefication temperatures.
The design and efficiency of the A.S.U determines the quality of the final product i.e. Oxygen and Nitrogen in terms of quantity and quality. The Boschi design A.S.U features a complete Aluminium structure wherein the entire upper column is a packed column thus reducing the operational pressure and increasing the Oxygen, Nitrogen and Argon recovery.
Argon is recovered by a revolutionary technique employing full rectification without using the Hydrogen and De-Oxo unit thus saving further on power costs, operational costs and investment. This makes the Boschi design machines highly versatile and economical thanks to all the research and development done over the years.
5. Turbo expander :
The Turbo expander is a gas or oil bearing expansion refrigeration turbine that is much more efficient than any other expansion device.
It works on the technique of induced cooling via expansion due to which the operational pressure of the plant is further reduced and the performance of the distillation column is stabilized for constant production and high purity.
