Nitrogen Gas Plants

Product Details:

We manufacture Pure Nitrogen Plant.

Process Description:

• Air compressor low pressure: Air is compressed at a low pressure of 5-7 bar (0.5-0.7 mpa). Air can be compressed at such low pressure by trouble free rotary compressor (screw / centrifugal type advanced technology is employed in lieu of old bulky piston compressor)
• Pre cooling system: The second stage of the process uses a low pressure refrigerant for pre-cooling the processed air to temperature around 12 deg c before it enters the purifier
• Purification of air by purifier- The air enters a purifier consisting of twin molecular sieve driers, working alternatively. The molecular sieves remove the carbon dioxide moisture from the process air before the air enters air separation unit
• Cryogenic cooling of air by turbo (expander)- The air has to be cooled to sub zero temperatures for liquefaction the cryogenic refrigeration the cooling is provided by highly efficient turbo expander, which cools the air to temperature almost below -165 to-170 degc
• Separation of liquid air into oxygen and nitrogen by air separation column oil free, moisture free and carbon dioxide free air enters into low pressure plate fin type heat exchanger where the air is cooled below sub zero temp, by air expansion process in the turbo expander. Due to the excellent thermal efficiency we can achieve a temperature difference delta t as low as 2 deg c at the warm end of these exchangers . air gets liquefied when it enters the air separation column gets separated into oxygen nitrogen by the process of rectification. liquid oxygen is available at the outlet of the asu at a purity of 99. 6%. liquid nitrogen is also available at the outlet as a alternate product at purity of 99. 99%(upto 3ppm as required). Nitrogen gas will be available as a by product
• Compression of oxygen filling in the cylinder- The final product in the form compressed oxygen/nitrogen goes to the high pressure oxygen cylinders at 1 50 bar or upto higher as required or for pipeline supply or captive consumption or for liquid plants to fill in cryogenic liquid tanks.

Product Details:

We manufacture Nitrogen Gas Plant (Low Pressure).

Salient features of nitrogen gas plants (low pressure):

• Purity of oxygen produced from all plants is minimum 99. 6% and nitrogen purity can be available up to 1-3 ppm (depending upon requirement of the customer)
• All plants use “oil free” rotary screw /centrifugal oil compressor working between 5-7 bar
• All plants incorporate aluminum brazed exchangers and packed columns for high efficiency
• Turbo expanders (gas bearing) for trouble free operation
• All plants above “500m3/hour ” can supplied with automatic plc control
• Engineering support along with complete quality control is provided by our company
• We provide qualified engineers for supervision, installation and start up of all our plants as well as training of manpower at customers’ site
• Very low power consumption with proven performance and virtually zero maintenance required for the machines.
• 100% reliability for oxygen gas quality for industrial hospital use

Main Equipments:

• 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
• 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
• Universal boschi 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)
• 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.
