Small Capacity Low Pressure Gas Pipeline Oxygen Nitrogen Plants

Range 40 TO 800M3/hr.
Purity oxygen: 99.6%. Nitrogen: 99.99% or 3PPM
Operating Air Pressure- 0.6 TO 0.7Mpa

Main Components:

(I) Air compressor: Screw/ low pressure- type:
We employ the most advanced compressor series available in the market. They have a unique combination, meeting customer requirements for low installation, operating and maintenance costs with high dependability and ease of use.

Screw type rotary compressors are one of the most advanced and trouble free.

Centrifugal Type Compressor: No other turbo type oil free compressor can match its efficiency and economy. This ensures a consistent and highly reliable source of air supply. Maintenance is extremely low. Oil free piston compressor are also very successful due to V-Type configuration on very low working pressure.

(II) 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. We are using highly reliable compressors of European origin.

(III) 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).

(IV) Air separation Unit:
The Key to the entire Air separation Process lies within the Air Separation Unit (A.S.U). Here, the mixture of Oxygen and Nitrogen is separated by virtue of the difference in their liquefaction temperatures. Liquefied air is sent to the lower and upper column using a double rectification process at temperatures below (– )180 deg centigrade.

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 highly efficient fin type aluminium heat exchangers and column, wherein the entire upper column is a packed column thus reducing the operational pressure and increasing the Oxygen, Nitrogen and Argon recovery.

Argon Recovery Plants

Argon is recovered Above 1000M3/Hour Oxygen Plants 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.

Note: Check USA & Germany manufacturers for technology comparison.

(V) Turbo expander:

The Turbo expander is a gas 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 oil bearing turbine expander.
