Gas Generator And Plants
We manufacture generator and gas plants. SAM Gas Projects (P) Ltd is a technology-driven USD 2 million company that infuses engineering with imagination.
PSA Nitrogen Gas Generators
| An ISO 9001:2008 certified company, SAM Gas Projects Pvt. Ltd. is a leading manufacturer, supplier, and exporter dealing in premium quality Nitrogen Generators. Our world class Nitrogen Gas Generator works on PSA technology. PSA stands for Pressure Swing Adsorption. This is the separation technology which separates nitrogen and oxygen molecules from rich compressed air. Commercial nitrogen production process usually employ carbon molecular sieves as adsorbents. In PSA, the oxygen is adsorbed to its equilibrium value much faster than nitrogen because oxygen which is smaller in size (kinetic diameter 3.46 A.o) diffuses much faster in carbon molecular sieves than nitrogen (kinetic diameter 3.64 A.o).
Flow Scheme for PSA Nitrogen Gas Generator
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.
Purity of Nitrogen
If you want pure Nitrogen, what you need is to select our PSA nitrogen gas generator. Nitrogen purity in the range of 99% to 99.9999% can be achieved through our nitrogen gas generators. Our PSA nitrogen gas generator produces raw nitrogen of 99% to 99.99% purity. By adding purification modules to this unit, nitrogen of 99.9999% purity can be achieved. Following are the generator models to produce different nitrogen purities:
• MS model
• Deoxo Model
• Cu-Deoxo Model |

Oxygen Gas Generator
| Our oxygen gas generators work with PSA (Pressure Swing Adsorption) technology. Using this technology, we produce oxygen gas generators that are low on maintenance, and highly economical while they produce the desired results in a hassle-free manner. These generators absorb nitrogen with the help of two absorption vessels filled with World's most efficient zeolite molecular sieves responsible for nitrogen absorption. |

PSA Medical Oxygen Generator
| Principles:
PSA medical oxygen generator uses zeolite molecular sieve as sorbent, produces oxygen by making use of the PSA principle. Under certain pressure, zeolite molecular sieve has different oxygen/nitrogen adsorption capacity, i. E. Much more nitrogen adsorption capacity than oxygen adsorption capacity. PLC controls pneumatic valve on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces oxygen with desired purity. |

Endo & Exo Gas Generators
| ENDO GAS GENERATOR :
In view of fundamental importance of carbon in determining the mechanical properties of steel, special attention has been devoted to those controlled atmosphere processes requiring control of carbon exchange between the furnace atmosphere and work being treated. To characterize the carbon exchange, the term carbon potential has been introduced (this denotes the carbon content which a pure iron specimen takes up in equilibrium with thw furnace atmosphere). The endothermic gas yields a potential between 0.7 to 0.9 which corresponds to the surface carbon content aimed at in the majority of processes. Endothermic atmospheres are used principally in the heat treatment of carbon steels and may be slightly carburizing to low carbon steels. These atmospheres have sufficient reducing constituent to prevent effectively any oxidation of the material being processed. They are substantially neutral to carbon steels.
Endothermic gas is produced by the reaction of an air-gas mixture ranging from 25 to 40 % of perfect combustion. Since reaction in this range is endothermic, it is necessary to supply external heat. The process is based on single catalytic cracking of LPG or natural gas with accompanying admission of air at such a rate that the product gas after cracking contains only CO, H2, N2 and traces of CO2 and moisture.
CO : 28 to 30 %
H2 : 20 to 25 %
CO2 : 0.1 to 0.5 %
N2 : Balance
Our endothermic gas generator consist of a mixer unit, cracking retort, gas cooler and control panel. All equipments are accommodated in a single compact unit. The reaction takes place in presence of high activity catalyst at a working temperature around 1050 deg C. Heating of the retort is affected electrically by heating elements around the retort.
Feed Stock : LPG or Natural Gas.
Capacities : 5 NM3/hr to 100 NM3/hr packaged unit. |

Compressed Air Dryers
| 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. |
