Perfect safeguards are incorporated in design against water and power failures, and also to keep the reaction temperature well under control.
NITROUS OXIDE at room temperature and atmospheric pressure is a colorless gas with a barely perceptible sweet odor and taste. It is non-flammable but will support combustion. At higher temperature nitrous oxide decomposes into nitrogen and oxygen. Nitrous oxide is moderately soluble in water, alcohol and oils. N₂O, also known as laughing gas finds its use as anesthetic agent. So far this has become a standard anaesthetic agent world over and medical operations are performed with the help of this gas. There are other uses of nitrous oxide which have been developed in food, cosmetics and electronic industry, for example it has become a good whipped cream propellant. This has become a propellant for high quality perfumes and cosmetics. It is used for Cryosurgery. Nitrous oxide as an oxide gas for atomic absorption in spectrophotometer and as fuel oxidant for racing vehicles.
The slight oxidizing property of N₂O is used for etching microchips. This application is now consuming upto 30% of all the nitrous oxide produced in Korea and Japan. With the increase in standard of living of third world countries nitrous oxide consumption is bound to increase.

GASLAB designs and supplies complete hydrogen gas plants with cylinder filling facility.
On small scale Hydrogen is produced from electrolysis of water in either Knowels type Mono Polar Cells or Filter press type Bi-polar cells known as electrolysers.

Knowel's Type Electrolytic Cells
1. Tanks and bells are welded by special quality electrodes to avoid Hydrogen and Caustic soda embrittlement. 2. Bells are manufactured out off C.R.C. Sheets which are specially recommended for Caustic soda handling. 3. The Asbestos diaphragm cloth is manufactured from 100% pure long fiber asbestos without cellulose core and closely woven to avoid pin holes. 4. Extra length of cloth is provided at the bottom to guard against bye-pass of gases. 5. Ebonite Insulators are tested against warping under high temperature and they are checked by Meger for infinity resistance. 6. Nickelling of Anodes is done under strict supervision for a minimum of .002 thick coarse deposit and each plate is tested chemically for pores. 7. The bells are fabricated by special fixtures and pneumatically tested to avoid leakage. 8. Side plates of bells are welded to avoid leakage. 9. Each Electrode plate is made straight by special Jigg and all the plates are perfectly parallel when assembled. 10. The 1" pipes are fixed on the bells with the help of a special Jigg to enable all the tubes to be equidistant and parallel for quick and easy fitting of the Electrode plate. 11. Each Electrode plate has two FULL-LENGTH copper rods.

Feed of water
The performance and long life electrolyser depends on the quality of feed water. As only Hydrogen and Oxygen together with some water vapour escape from the electrolyser. Each impurity introduced with the feed water will accumulate in electrolyte, i.e. Chloride, Sulphate and iron. The former two will have harmful effect on Nickel metal which leads to heavy corrosion and the later will cause impure Oxygen gas, The most suitable and economical method for production of pure feed water is by Ion Exchanger (DM water). The immediate detection of impurities in the feed water is its specific conductivity which should not exceed 2 x 10 ohm/CM Every cubic meter of Hydrogen produced, requirement 1 lt., of feed water, which is measured by rotameter provided with each plant.

Purity of Gases:
Hydrogen=99.8+ 2 by Vol.Oxygen =99.5+ 0.5 by Vol.

Gas Pressure:
Max. 250 mm of water Column which is sufficient for stroage in low pressure Gas Holders. When oxygen is not required to store in Gas holder it is vented through pressure balancing tank to atomsphere.
Air Pollution: (in filter press type) : NIL(in Knowel type) :Minor leakage of gases connot be detected, which cause caustic atomsphere in the cell room.

Fire Hazards:
(in filter press type) : NIL(in Knowel type) :1. In case of loose electrical connection.2. In case of Blocking of the cells from bottom by desposition of soild Caustic and Carbonate3. Short circuit due to leakage of electrolytes.

Design of Electrolyser
1. The cell is in circular shape for uniform distance between Anode and Cathode. 2. The asbestos diaphragm is fixed on solid frames with bolting, which keeps the generated gases separate and maintain uniform purity.3. The frames, center electrodes, end electrodes, end frames are fully machined from selected steel and Nickel-plated to have uniform pressure on each frames and gasket. Thus the iron in electrolyte and leakage is fully controlled.4. The installation of Electrolyte separation tanks, Gas coolers and Gas washing tanks are arranged in such a manner that the cell can be attended without dismantling the complete plant. The cell can be easily installed in a room of 15 feet height.5. The +Ve(Anode) -Ve(Cathode) connection are provided on top of cell to have minimum length of Bus Bars and maximum safety.6. The filter provided will remove any fine fibers of Asbestos, dust, rust and carbonate which causes resistance to electricity and reduce efficiency.7. The Anode and Cathode electrodes are designed and fabricated from 1.6 mm thick CRCA steel to have minimum over voltage of gases and uniform distribution of electrolyte and electricity.8. The plants are supplied with base frame and insulators ready to install without foundation. 9. The VE: 1000 and 2000 filter press type can be easily installed in parallel and series with 2000 Amps. Knowel's cells. The combination will produced more gas using the rectifier already in use.

The disconnected Knowel's cells can be kept as spare for replacement of damaged Knowel's cells. Thus cells can be replaced most economically.

Technology to generate whealth from waste:
Gaslabs has developed a new technology of EXTRACTING CO₂ FROM BIOMASSES. It has set up serveral plants running on Biomasses and demands are pouring. while introducing this technology for the first time in the world Gaslabs Asia is constantly working on design innovations of its plant based on fertilizer gases, breweries and distilleries to extract even more wealth from waste. Gaslabs' flue gas plant uses boiler or any furnace flue gas as a raw material thus doing away with costly liquid fuel which is generally costlier in Asian contexts.
The flue and biomass gas plants can be designed in the different capacities ranging from 30kg per hour to 2000kg per hour depending on the available input and client requirement.
Other options may be the plants that run on waste hard coke, nut coke, breeze coke and pearl coke.

Bye- Product based, Pollution free, Low priced Plant, Delivery more than purest CO₂
Gaslabs Asia plants are designed to use industrial bye products as their raw material, which works as a boon for DISTILLARIES and BREWERIES where fermented gases are produced in plenty and otherwise would go waste. GASLABS ASIA PLANTS RECOVER ODOUR-FREE, FOOD GRADE CO₂ FROM THEM. Plants themselves are 100% POLLUTION-FREE causing no environmental imbalances, instead they capture CO₂ which otherwise would have been mingled with the environment.
Gas quality is guaranteed to be food grade and 99.99% pure in most cases. These plants are not only cost-effective in running but they are MOST REASONABLY PRICED to install too!-as they comparative study vis-a-vis to their features will reveal
In our CO₂ production plants based on any fuel burning we can co-produce N₂ and DISTILLED WATER as well.

Concept: Easy, Cheap Maintainence and Right Automation
Undoubtedly Europe was first to use CO₂ for industrial purposes. It's countries designed various plants and innovated new technologies, spreading them out to the world.
But unfortunately, in design Western Industry even now supports the 'Disposable' tag. A good reason for this may be the cost of repair & maintainence though. While the opposite is true for Asia. Though Gaslabs Asia makes widest range of plants ( from semi-automatic to full PLC computer controlled) it supports the Asian line. All Gaslabs' plants are MODULAR IN DESIGN with JUST RIGHT AUTOMATION, thus making maintainence and repair easy & cheap. Gaslabs' plants also have plenty of space in their floor plan which is relatively less costly in Asia.
JUST HOW MUCH AUTOMATION does a client need? Many times a total automation, for an Asian environment may not prove to be as effective and hassle-free as manual or semi automated processes. At Gaslabs Asia, our first concern is plant uptime, productivity and automation-in that order.

Our own running production plant becomes test bench of our new ideas
We believe that New Ideas should prove their dependability and we implement it with conviction. Our own CO₂ plants work as testing ground to our innovations before they are commercially made available to our clients. This also gives us an opportunity to understand their problems which they might encounter in future. We make every attempt to eliminate them at design level itself.
At Gaslabs Asia new ideas get into practical shape only when they have withstood our rigorous testing measures and have proven their dependability.
For example our Biomass Plant took 5 long years to see the light of the day.
