PSA / MEDICAL OXYGEN GENERATORS

01 Oxygen Flow :-

PSA based oxygen generators are most suitable for flow up to 150 – 200 Nm3/hr.

02. Oxygen Purity : -

Can be generate at 90- 93 % purity with balance inert gases present in atmosphere.

03 Oxygen Pressure :-

Oxygen can be generate at 4.5 to 5.0 Kg/cm2 g pressure by PSA modules directly without any booster

04 Dew Point :-

Generally our Oxygen generator deliver dry gas up to (-) 40 to (-) 50°C. We offer online measuring instrument to measure dryness of gas.

APPLICATIONS:

Our Oxygen generators are widely used in the following applications

•Hospitals as a backup of Oxygen cylinders

•Paper & Pulp industry for Oxy bleaching

•Glass industry

•Metallurgical industry

•Furnaces for oxygen enrichment

•Ozone Generators

•Fish farming etc

HOW IT WORKS

Oxygen is generated by PSA (Pressure Swing Adsorption technology). The Atmospheric air contains of 20-21% oxygen. In this system there are two towers filled with Zeolite Molecular Sieves & Activated Alumina extract the oxygen from air. Both towers are inter-connected with change over valves.

 PSA NITROGEN GENERATOS

We are a leading manufacturer / Exporter of Nitrogen generators. Such type of Nitrogen generators are most suitable when high purity is required ( more than 99%)

Technical Certitude :

01 Nitrogen Flow :-

Can be generate 1 – 3000 Nm3/hr with multiple PSA modules

02. Nitrogen Purity : -

Can be generate at any desired purity up to 99.9999% with different models

03 Nitrogen Pressure :-

In most application offered Nitrogen at 5 Kg/cm2 g pressure is suitable however it can be generate up to any desired pressure with Nitrogen gas boosters.

04 Dew Point :-

Generally our Nitrogen generator deliver dry gas up to (-) 40 to (-) 80°C. we offer online measuring instrument to measure dryness of gas.

HOW IT WORKS

•Atmospheric Air contains of approx. 78% Nitrogen & 20.9 % Oxygen.

•The PSA process utilized CMS to extract the nitrogen from atmospheric air.

•The PSA process comprise 2 – vessels filled with Carbon molecular sieves & Activated Alumina

•Once Oil free clean air passed through the vessel, pure nitrogen comes out as product gas.

•The exhaust ( adsorbed Oxygen) gas is vented to atmosphere. Once molecular sieves saturated, the process switch over to other tower by automatic valves. In mean time saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure.

•Hence cyclic operation of 2 – vessels in nitrogen production & regeneration ensure continuous availability of Nitrogen gas to your process.

AMMONIA CRACKER

This is the cheapest method to produce Hydrogen gas for various industrial uses. In this system , Hydrogen gas is produced by dissociation of commercial Ammonia(NH3) . The dissociation of Ammonia gas take place at a temperature of 875 - 920°C in presence of Nickel Catalyst. Hydrogen and Nitrogen are generated in a cost effective way in a volume ratio of 3 : 1 or in a weight ratio of 14 : 3.

Cracking of ammonia is endothermic process in presence of Nickel Catalyst completes the reaction at around 875 to 900OC. Ammonia is passed through tubular retort filled with Nickel catalyst. The retort is fitted in an electrically heated furnace, which supplies the heat of reaction.

875O C

2 NH3 N2 + 3H2

Nickel Catalyst

The NH3 is coming from bottles or from an ammonia tank. The ammonia gas is pre-heated in a heat exchanger and vaporizer and then cracked in the main furnace unit. As a result of complete dissociation into hydrogen and nitrogen, very little undissociated ammonia remains and the dew point temperature of the resulting gas is very low (below -30°C).

Technical Certitude :

01 Hydrogen Flow :-

Hydrogen cracked gas is generated from 1 Nm3/hr to 500 Nm3/hr in a single furnace

02. Hydrogen gas Purity : -

It produced standard cracked gas mixture in a ratio of 75% H2 + 25% N2. It can be further purified up to 99% hydrogen by gas purifiers in downstream depends on customer requirement.

03 Cracked gas Pressure :-

Cracked gas can be generate at 4.5 to 5.0 Kg/cm2 g pressure by our generator directly without any booster. We also offer integrated booster on demand of customer for further boost the cracked gas.

04 Dew Point :-

We design our system to deliver dry gas up to (-) 40 to (-) 80°C on demand and requirement of customer. We offer online measuring instrument to measure dryness of gas.

PEM HYDROGEN GENERATORS :
85% of the energy consumed globally is provided by fossil fuels, namely coal, oil and natural gas. Consuming fossil fuels produces green house gases and other byproducts, causing climate change and air pollution. The growing demand of energies requires a rapid shift from fossil fuel to renewable energy sources such as wind, solar, biomass etc. In this context, Hydrogen is proposed as a secondary source of energy.

PEM (Proton Exchange Membrane) water electrolysis system / process is an endothermic process and electricity is applied as the energy source. The water electrolysis reaction is thermodynamically possible at potential higher than 1.23V vs RHE( Reversible Hydrogen Electrode). The thermoneutral potential at which the cell can operate adiabatically is 1.48V vs RHE. The PEM Hydrogen generators operate at potential over 1.48V vs RHE and heat is generated by the reaction.
