Description :
Oxygen Gas Generators

This is Molecular sieves Technology to produce low cost Oxygen from air, MHTPL has long experience and know-how in Design and manufacturing of such plants. Molecular sieves remove moisture and Nitrogen from Air. So upto 95% purity dry Oxygen gas is produced. We offer following 2-designs.

PSA Design

This is PRESSURE SWING ADSORPTION process.

It has 2-vessels filled with Molecular sieves. Clean compressed air at 30ļ C temp. is passed through 1-vessel and oxygen comes out as product gas. The other vessel is depressurized to atmospheric pressure and purged with little quantity of Oxygen coming out from other vessel. This regenerates Molecular sieves for use in next cycle. Thus 2-vessels keep cycling alternately in Oxygen production and Regeneration making Oxygen gas available continuously. These units are designed and supplied for 90% to 95% (Max) Oxygen purity.

From PSA design Oxygen pressure is available directly upto 4 Bar (A) without need of Oxygen compressor. So this design is preferred for medium pressure Oxygen requirements.
Standard sizes available from 1 to 500 Cubic meter per hour Oxygen.
Very simple in construction and very easy in maintenance. So more popular for most Oxygen requirements.
Power consumption is 1-KW per Cubic meter in smaller sizes and 0.7 KW per Cubic meter in bigger sizes.

Salient Features

Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment.

Lower Space Requirement
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory.

Fast Start-up
Start-up time is only 5 minutes to get desired Oxygen purity. So these units can be switched ON & OFF as per Oxygen demand changes.

High Reliability
Very reliable for continuous and steady operation with constant Oxygen purity. Plant availability time is better than 99% always.

Molecular Sieves Life
Expected Molecular sieves life is around 5-years,

VPSA Design


This is VACUUM PRESSURE SWING ADSORPTION process.

In this design there are 2 or 3 Molecular sieves vessels which cycle alternately-in Production and in Regeneration. Feed air pressure is generally 1.1 to 1.5 Bar (A) which gives Oxygen production at 1.05 to 1.3 Bar (A). Regeneration of Molecular sieves is done by a vacuum pump at 210mm Hg Absolute pressure. The waste gas is 85% Nitrogen and 15% Oxygen which is vented to atmosphere through a silencer. Product Oxygen gas purity is 90 to 95%.

Higher initial investment as compared to PSA design.

Power consumption is comparatively lower. So this design is preferred and recommended for large capacity Oxygen plants

Power consumption is only 0.45 KW per cubic meter Oxygen.

Oxygen plant sizes available from 200 to 3000 Cubic meter per hour.

Direct Oxygen production pressure only upto 1.3 Bar(A). For higher pressures. Oxygen compressor is provided.

Oxygen purity

Oxygen Purity available from 85% to 95% as per customerís requirement. Commonly used 93% purity Oxygen has 2.5% Nitrogen and 4.5% Argon.

Plant capacities
-PSA Oxygen Plants: 1 to 500 Cubic meter per hour.
-VPSA Oxygen Plants: 200 to 3000 Cubic meter per hour.

Utilities needed
The only utilities required are Cooling water & Electrical power. So cost of electricity consumed is the cost of Oxygen production.
