Nitrogen Gas Plants

Our gas generators are of optimum quality, durable and easy to handle. Our on site PSA nitrogen generators are custom made and can be adjusted to give the desired nitrogen quality for your process and application.

Oxygen Gas Plant

Air is taken from an air compressor and oxygen is separated form other gases, including nitrogen with the help of special grade of zeolite molecular sieves. The process involves two towers filled with zeolite molecular sieves which adsorb nitrogen and subsequently discharge waste. In Gas Generation Process the oxygen generated is 85-94% pure. When nitrogen saturates from one tower, this process changes over to the other tower, thus helping in the process of continuous oxygen generation. These are suitable for medical use as well, for providing oxygen round the clock. Our range is known for low cost, decreases the administrative work & ensures to provide continuous and reliable oxygen supply.

Hydrogen Gas Plant

Hydrogen Plant, We are engaged in offering a wide range of Hydrogen Gas Generators, which includes Water Electrolysis Based Hydrogen Generator and Cracked Ammonia Based Hydrogen Generator. These are catalytic cracking units in which ammonia is dissociated to nitrogen. The produced gas has 75% hydrogen and 25% nitrogen, which is further purified in a molecular sieves unit by removing un-cracked ammonia and moisture.

Acetylene Plant

The Acetylene Plant and equipment is used for different industrial and other purposes. These are manufactured in compliance with international standards using advanced technology.

Air Gas Dryers

Selection of Air Dryer

Why Dry Air - Compressed air is used in industries for various applications in pneumatic tools, pneumatic instruments, pneumatic machines and in a variety of production processes. The consequences of using wet air are rust and scale deposits in steel pipes, increased resistance in flow, malfunctioning of process control instruments, corrosion and damage to electromagnetic valves and pneumatic system, peeling and blistering effect on spray painted surface etc. Thus it will affect the quality of product and lead to excessive maintenance cost.

Ideal compressed Air System - Air from the compressor has excessive moisture and contaminants. The sketch below shows a typical Compressed air system to remove these damaging impurities and get Clean and Dry air.When compressed to 7Kg/cm2g the temperature of discharge air reaches around 140oC. The after cooler and Separator installed after the compressor will cool the air, and removes 90% of moisture and oil. For instance, when the compressor takes in 100 NM3/hr of ambient air at 40oC and 50% relative humidity, at 7Kg/cm2g the after cooler will condense an average of 30 liters of water in 24 hours.

If the outlet air temperature from the after cooler is 40oC, it still contains 8000 ppm moisture. At 45o C compressed air contains 10,500 ppm, at 50oC, 13,500 ppm moisture which is removed by Air Dryer. Therefore, lower the temperature of air at dryer inlet, smaller would be the size of Air Drying Unit.

Pre Cooler - If compressed air temperature is higher than 400C, it is essential to precool it to 400C temperature before Air dryer. This cooling is achieved in a shell & tube type heat exchanger using cooling water. Due to this cooling some moisture condenses out which then helps in keeping the moisture load low on Air dryer and thus better Dew-point of air.

Dew Point Selection - "Dew point is the measure of moisture in Air. It is the temperature at which moisture present in the Air, starts condensing. Lower the Dew Point, more dry is the Air”. Air of (-) 40°C Dew point means no moisture would condense unless the temperature of the compressed air goes below (-) 40°C. For most industrial applications Dew point of around (-) 10°C is satisfactory. However, as a common industrial practice, most of Air dryers are rated for (-) 40°C Dew point. Lower the Dew point, higher would be the operating cost. Hence, proper selection of Dew point is very important for economical operation.
