Oxygen, Nitrogen and Argon will be produced by air separation using cryogenic distillation process.
Air Compression, Cooling & Purification
The atmospheric air will be compressed in a multistage centrifugal turbo air compressor (ATC) equipped with suction air filter and inter/ after coolers. The heat of compression will be rejected in the intercoolers, after coolers and further cooling upto desired temperature will be done in air water tower through waste nitrogen gas & chilled water. A demister will be used to free water from the air stream. Moisture separator shall be provided.
The pre-cooled air will be passed through twin bed adsorber towers containing activated alumina and molecular sieve to remove moisture, carbon dioxide, as well as hydrocarbon impurities from air steam. After passing through the bed, the air passes through a dust filter that removes any molecular sieve fines that may be present. A small stream of air will be withdrawn downstream of the dust filter to meet the instrumentation air requirement of ASU.
One of the two vessels will be in operation while the other will be reactivated by waste Nitrogen coming form the cold box. The regeneration gas (waste Nitrogen) will be heated in electrical heater in the heating cycle of regeneration.
At the outlet of the air purification unit, the main stream of purified air will be divided into two streams. While the first stream of purified air (Medium pressure air at 5-6 kg/cm2 g) will enter the main exchanger in the cold box, the other stream of purified air will be further compressed to high pressure in a multistage centrifugal booster air compressor (BAC) and then it will enter the cold box. Both the medium MP (medium pressure)and HP air will be cooled down by heat exchange with the counter current liquid Oxygen to produce product gaseous Oxygen, product gaseous Nitrogen and waste gaseous Nitrogen steam in the main exchanger (inside the cold box).
Air Distillation
The air distillation takes place in the Air Separation Unit cold box consisting of main heat exchanger, nitrogen heaters, bottom column, top column, main condenser, argon condenser, argon columns, expansion turbine, cryogenic pumps etc.
The MP air (at 5-6 kg/cm2 g) which will be nearly to dew point, enters the bottom column which perform the first separation.
Part of the HP air will be used to produce required refrigeration by taking it out of the main exchanger at an appropriate point and expanding it in an expansion turbine. This expanded air will be fed to the MP column (at the bottom of the bottom distillation column). The other part of the HP air will be further compressed in the booster connected to the turbine to elevate the pressure level to vaporize liquid Oxygen in the main exchanger and then expanded through an expansion valve before it enters the MP column (i.e. at the bottom of the bottom distillation column). Oxygen and Nitrogen will be separated from the air by Cryogenic distillation from the cold box.
In order to produce Argon, the Argon rich stream of liquid from intermediate level of the top column will be fed into the pure Argon column where it is stripped of its Nitrogen content. Pure liquid Argon product from the bottom of the column will be sent to the storage tank.
All distillation columns shall be with structured packing for high degree of efficiency with minimum energy consumption.
Layout of the Plant shall be such that control room and cold box are located near compressor building and easily approachable.
