The Oxygen Generation Plant

The Hi-Tech’s VPSA Technology Based Oxygen Generation Plants Are designed for on-stream application with need for low-cost oxygen with a purity of around ~90% to 94% V/V and balance gas consisting of Nitrogen and argon,where it is not economical to produce the required oxygen with on-site cryogenic units or take it from Cryogenic liquid oxygen storage Tanks/Systems.

The VPSA oxygen plants are providing low-cost oxygen with a reliable and trouble-free process the capacities of the oxygen plants range from small plants requirements of only several Nm³/hr up to large-scale plants with several Nm³/hr oxygen products flows.

The plants are engineered to deliver sizes, as well as turn-key customized systems for highly reliable on-site oxygen source with low capital and operating costs

Advantages

  • Economics

Cost saving in the range of 40-60% over liquid supply Systems and up-to 80% for Cryogenic Plant.

  • Highest Reliability

The VPSA system provides the highest reliability the control system allows for the production of oxygen at the specified flow & purity within a short time of demand using a simple push button. this on/off operating capability is not available from cryogenic plants.

  •  Easy Partial Load Operation

The plant is automatically adjusted to the actual product flow requirement and operates in an energy-saving partial load mode.

  • Energy Efficiency

Lower energy consumption than cryogenic units.

  •  Fully Automatic Operation

PLC-based control system controls the purity and the flow by automatically adjusting the cycle time of the VPSA system.

  • Remote control

A  Profinet or LAN port is provided for the communication with complete Plant Directional Control System with optional Modem Board for Remote Control.

Plant Unique Features

  • Completely Pre-Piped & Skid Mounted.
  • Containerized Shipments right from factory.
  • Critical process parameters monitored and
  • Recorded every 500 milliseconds.
  • Automatic turndown capability from 100% to 0% flow capacity.
  • Designed in accordance with local standards.
  • Automatic and unattended operation.
  •  On-site start-up assistance by Hi-Tech’s Engineered Solutions technicians anywhere in the world.

Typical Applications

Oxygen VPSA Plants supplied by Hi-Tech Engineered Solutions range in the size of a few 50 Nm3/hr up to 600 Nm3/hr with an oxygen product purity of ranging from 90% ~ 95% V/V.

For many Processes using oxygen rather than air reduces vent gas quantities and reduces energy and capital cost requirements.

  • Metal Industry

Furnaces in lead, copper and zinc industry.

Oxygen-Fuel Burners.

Chemical leaching for minerals extraction.

Uranium Recovery.

  • Pulp and Paper industry

Oxygen bleaching and oxidation.

  • Chemical Industry

Chemical oxidation reaction using oxygen reduces.vent gas quantities and hence energy and capital cost.

  • Water and Waste Water treatment

Oxygenation and Ozone Treatment.

  • Glass Industry

Furnace enrichment oxygen burners have a much more intense flame, So the heat transfer is greater & furnace can be smaller and less fuel is consumed.

  • Hospital

For artificial respiration.
