With respect to FIG. 2, the apparatus comprises an air-suction filter 200, a compression assembly 201, a plurality of filters 211, a dryer 206, a plurality of after-coolers, a storage assembly and a distribution unit 207. The air-suction means is a micronic air suction filter to suck an atmospheric air. The compressor assembly 201 comprises 5 compression stages i.e. two low pressure compression stages & three booster compression stages and a plurality of drain valves 209. The 5 compression stages comprise a first low pressure compression stage. The first low pressure compression stage comprises a two low pressure cylinder assemblies, a two inter-coolers 202 and a purge bottle 203. The first low pressure compression stage follow a compression process. The second low pressure compression stage is connected next to the first low pressure compression stage. The second low pressure compression stage comprises a low pressure compressor, an inter-cooler 202 and a purge bottle 203. The second low pressure compression stage follow the compression process similar to the first low pressure compression stage. If the air is required to boost, then, air from second compression stage is passes to Booster compression stages. If nitrogen is to be generated and compressed, then the air from second stage is passes to Nitrogen generator through air receiver & filters. The nitrogen generation mechanism 208 comprises an air receiver, a moisture separator, a plurality of compressed air filter, a heater, a membrane unit, a gas analyzer and an outlet valve. The generated nitrogen then, passes to booster compression stages. Each booster compression stage comprises a high pressure compressor, an inter-cooler 202 and a purge bottle 203. The three booster compression stages follow the compression process similar to the first low pressure compression stage. The compressed air or nitrogen from a first booster compression stage is passed to a second booster compressor stage. The compressed air or nitrogen from a second booster compression stage is passed to a third booster compressor stage. The plurality of after-coolers is connected to the three booster compression stages stagewise. The plurality of after-coolers is further connected to the purge bottle 203 for de-moisturizing. The plurality of drain valves 209 are connected for condensate removal to the plurality of purge bottles 203. After last stage booster compression, cooling and condensate removal , air or nitrogen passes to the plurality of filters 211. The dryer 206 is connected next to the plurality of filters 211. The air or nitrogen is further passes to the dryer 206 to dry it as per required dryness. The first low pressure compression stage, the second low pressure compression stage and the three booster compression stage are arranged in a tandem mode. The storage assembly is connected to the outlet of the dryer. After dryer, air or nitrogen is passes to the corresponding storage bottles. The storage assembly 8 bottles with storage capacity of 40 litres per bottle. The 4 bottles (205) out of 8 bottles store compressed nitrogen and remaining 4 bottles (204) store compressed air. The distribution unit 207 is connected at the outlet of the storage assembly. We can either store the air or nitrogen in storage bottles (204 or 205 respectively) or can send to the distribution outlet to fill the outside bottles directly.
[0025] The atmospheric air is drawn through the micronic suction air filter into first stage two compressor cylinders. Here the air is compressed and then passed through the first stage inter-coolers. On cooling, the moisture is formed which is collected in the purge bottle from where moisture is drained by the automatic drain valves. The air from the purge bottle is then admitted to a 2nd stage compressor cylinder. In the 2nd stage, the air is further compressed, passed through second stage inter-cooler followed by the purge bottle. The air is then passed to either the 1st stage of booster compressor or to the air receiver, depending upon, whether the requirement is of air or nitrogen.
[0026] According to one embodiment herein, if a high pressure air is required then the air passes to the 1st stage booster compressor from the 2nd stage purge bottle. If compressed air is required, then,the air then passes through the 1st stage booster intercooler and the purge bottle and then transferred to the 2nd stage booster. In 2nd & 3rd stage booster compressor air passes through same cycle as in the 1st stage booster compressor. After compressing and cooling in the 3rd stage booster compressor to an operating pressure of 200 , the air enters to the dryer through the filters to remove an oil and moisture content from the air. A dew point of air is displayed by an online dew point meter. The air is then delivered either to the storage bottles (4 nos. of 40 ltrs.) or directly supplied to a user point through the distribution connection at 200 .
[0027] According to one embodiment herein, If compressed nitrogen is required, then, the air from the 2nd stage purge bottle is initially passes through the air receiver to the moisture separator and then to the compressed air filters to remove all suspended particles before entering the nitrogen generation mechanism. Further the air passes through the heater to achieve controlled optimum temperature for most efficient operation of the membrane unit. As cleaned air passes through microfibres of the membrane unit, the oxygen and oxygen bearing molecules like , etc permeate through walls and minimum 98% pure nitrogen is left over and collected at an outlet of the membrane unit. The gas analyzer continuously monitors a purity of generated nitrogen. If purity is below accepted limit of outlet, then the nitrogen is vented out till desired purity of gas is achieved. The specified pure nitrogen is stored in nitrogen receiver and further boosted to higher pressure in the three booster compression stages.
[0028] According to one embodiment herein, nitrogen from the booster compression stages passes through the after-cooler and the purge bottle to remove the condensate. After last stage booster compression, cooling and condensate removal, nitrogen passes to the plurality of filters. The filters remove the oil from nitrogen and transfer it to the dryer. The filters control the content of oil in nitrogen to a maximum level of 0.003 of nitrogen. The dryness is indicated on an electronic dew point meter fitted on the dryer. The nitrogen is then delivered either to the storage bottles 4 nos. of 40 ltrs. or directly supplied to a user point through the distribution unit. The high-pressure nitrogen is delivered to the user point directly by a flexible connection.
