OXYGEN NITROGEN PLANT

BASIC PRINCIPLE :

  • Oxygen and nitrogen are generated simultaneously when an air separation plant taps atmospheric air though low pressure cryogenic distillation process.
  • The design of the plant is based on the advanced low pressure technology process of Mandressi Italia using rotary screw compressor and turbo expanders.
  • The atmospheric air enters the Molecular Sieve Purification System which removes the moisture and Co2 from the processed air.
  • The air is liquefied with the help of cryogenic cooling using latest plate and fin high efficiency heat exchangers and turbo expanders.
  • The air gets separated into oxygen and liquid nitrogen in the air separation column. The final product is either stored into cylinders at the required pressure or routed into pipeline for application.

TECHNOLOGY

Our company uses the latest technology and internationally approved components in the manufacturing of the oxygen and nitrogen generating plants. The systems are popular for having a number of features for instance low power requirement, low upkeep expense and maximum output. We are a Certified EOU (Export Oriented Unit) company so enjoying the facility of purchasing raw materials at tax free rates and, in turn, providing the plants at competitive rates. Our company along with its designing and manufacturing facilities is approved all over the world for exceptional skill in designing, manufacturing, install lation and commissioning of our products.

SALIENT FEATURES OF THE PLANTS :

  • Easy to start and run
  • Fully automatic operations
  • No special civil foundation required
  • Oil-free design
  • Exceptional safety features
  • Long service life
  • Round-the-clock operation

PROCESS DESCRIPTION :

  • Compression of Atmospheric Air
  • Purification of Air
    COMPACT PROCESS SKID
  • Cooling of Air
  • Separation of Liquid Air Into Oxygen and Nitrogen
    LATEST LEAKPROOF STAINLESS STEEL COLUMN
  • Compression/Withdrawal and Filling of Oxygen and Nitrogen by latest liquid oxygen pump technology to fill bone dry high purity oxygen in Cylinders.

Note: Due to the latest liquid oxygen pump technology, there is now no need of old type of bulky oxygen compressors, no more break downs, moisture or rusting in cylinders.

SCOPE AND SUPPLY :

Air Compressor :

Our air compressors are supplied as per buyers’ choice. We offer a wide range of air compressors.The A-grade air compressors enhance life span and output quality of our machines.

Purification of Air (Process Skid) :

Process skid is very compact. All equipments are mounted on processed skid complete with gas/air/water lines for high purification of air. It is comprised of the following:

  • After cooler with tank
  • Nitrogen cooler with tank
  • Moisture separator
  • Chilling unit with freon unit
  • Oil absorber
  • Molecular sieve
  • Defrost heater
  • Manifold

Air Separation Column (Cold Box):

Air separation column-cold box consists of outer steel casing, main heat exchanger, liquifier, bottom column, top column, condensor, sub-cooler, liquid oxygen & nitrogen filter. Cooling pipe line, insulation material, digital electronic temperature indicator & scanner, pt 100 sensor, dp gauge monometer, expansion valve with long stem type with pointer & index & wheel.

Expansion Engine :

Complete with Motor/starter/starter shall be Siemens/ABB/Kirloskar, with hydraulic valve control bursting disc for safety, complete with Flywheel pressure gauge, Motor pulley V-Belts,Belt Guard slide rails interconnecting copper pipes (Inlet & Outlet)

Liquid Oxygen Pump :

Liquid Oxygen passes from the condenser to the liquid oxygen pump for filling gas into cylinders. The cylinder filling is done through the integrated liquid oxygen pump (Connected to cold box) which is designed to fill oxygen gas into cylinders at high pressure of 155-200 bar.

Cylinder Filling Manifold :

The CYLINDER FILLING MANIFOLD system provided with the oxygen cylinder filling plant is made to sustain high pressure at 155- 200 bar continuously.
