What is Ozone ?
Ozone (O3), the tri-atomic allotrope of Oxygen (O2) is a powerful oxidizing agent and as a strong disinfectant. It is an ideal choice for wide variety of industrial and household applications. Ozone is also used in medicine to treat over 200 diseases. Ozone is an unstable molecule and quickly converts back to oxygen. Hence it cannot be easily stored in containers.
Ozone is commercially produced, on site, by passing dry air or oxygen through a high voltage dielectric barrier (or corona) discharge.

Technology Of Ozone Generation
The feed gas (dry air or pure oxygen) is passed through two electrodes separated by a precise gap and a high quality glass dielectric. High frequency high voltage discharge in the electrode gap converts a fraction of the feed into ozone. Heat is generated at the two electrodes in the process. It must be efficiently dissipated to optimize ozone production.
Properties Of Ozone
  • Fast and powerful oxidizing agent and disinfectant
  • Quickly converts back to oxygen, leaves no residues
  • Good flocculent
  • Breaks up complex molecules into simpler harmless compounds
  • Destroys phenols, pesticides, herbicides and PCBs
  • Oxidizes soluble iron and manganese, cyanides, sulfites and nitrites
  • Oxidizes volatile organic compounds
Procedure

Ozone gas is produced by passing air through two concentric electroded having a Dielectric (Quartz or Ceramics) in between them; a high voltage 10,000 to 18,000 volts) is applied between both the electrodes to produce a corona of discharge. As air is passed through high voltage electric field, a portion of or air gets converted in Ozone gas, only a small portion of the Oxygen is converted in Ozone. By using as feed gas 1% or 2% and with oxygen 3% to 6% concentration of Ozone can be obtained at the same flow rate.

Either air or the oxygen is used as feed gas based on techno – economic consideration and the Ozone treatment application.
Facts And Findings
  • Ozone Gas acts 3200 times faster than Chlorine.
  • It has been proved that chlorine combines with contaminants in water to form chloramines and dichloromethane, which are not just eye and skin irritants but are also carcinogenic in nature and causes testicular and breast cancer. In fact chlorine and its compounds can mimic estrogen in human body, which may cause abnormalities and reproductive defects.
  • Ozone is more effective than chlorine and UV.
  • A residual Ozone concentration of 0.4 mg/ litre for a period of 4 minutes have micro-organism kill at rate of 99.9%.

Product Description
This system requires a feed of compressed air at around 7.0 kg/cm2g pressure and less than 40 Deg C temps. From an air compressor followed by after cooler/refrigerated dryer and filtration system. The air compressor is provided with all necessary accessories (By client). To remove oil vapors from the air, an activated carbon filter will be provided. This compressed air is then taken to a composite bed twin PSA unit containing activated alumina as bed support as well as drying media and Carbon Molecular Sieves which absorbs moisture, oxygen, CO2 and thus nitrogen gas comes out as product gas. At a time one tower is under absorption producing nitrogen while other is under regeneration at atmospheric pressure. For the automatic changeover of towers a suitable sequence programmer is provided. The nitrogen gas comes out of PSA unit at a pressure of 5.0 to 5.5 kg/cm2g and contains 0.5% Oxygen. To avoid any surges because of changeover from one tower to another, a suitable nitrogen surge tank is provided.

The system is complete with required instruments for smooth and safe operation.

Heatless type Air Dying Unit
Heatless type dryers do not require any heating of the desiccant for regeneration and therefore are very simple in design and smooth in operation. Heat reactivated dryers have become obsolete due to their high operating costs and high maintenance requirements.


In heatless dryers two vessels filled with desiccant are provided which cycle automatically, providing dry air continuously. In these units, wet air enters the bottom of one vessel passes upward through the desiccant bed where the moisture is adsorbed.. The clean dry air comes out from the top.

A small portion of the dry air is passed downward through the desiccant bed in the second vessel which is under regeneration. This moisture laden purged air is then vented out to the atmosphere. The purge air loss is around 5% of the total air flow rate. At preset intervals, the vessels changeover automatically and the dry air is available continuously without any surges. The purge air loss is around 15% if dew point of (-)80 C is required.

HOW GENERATOR WORKS
Oxygen generator makes oxygen by taking air from an air compressor, separating oxygen from nitrogen and other gases by means of special molecular sieves which NEVER NEEDS REPLACEMENT. The process is totally REGENERATED. It utilizes two towers filled with special molecular sieves which adsorbs the nitrogen. During regeneration, this adsorbed nitrogen is subsequently is discharged as waste. The resulting product gas is around 85 to 90% pure oxygen available at around 3.0 kg/cm square g pressure. The system gives a continuous supply of oxygen by automatic switching towers on a timed cycle. It can be adjusted for a oxygen purity upto 92%, although the most economical for practical purposes is 85%. The gas is very very dry having about 2 ppm moisture only.
Refrigerated
Compressed                                                                           AIR DRYER
WHY YOU NEED DRYER?
Compressed Air contained 58.5 gm of moisture per NM3 at a pressure of 7 kg/cm2g which creates a big nuisance to the efficient working of Pneumatic Systems. The possible consequences are rust and scales deposits in steel pipes, increased resistance To flow, malfunctioning of process control instruments and equipment corrosion and damage of electro-magnetic valves and pneumatic instruments, solidification of media in pneumatic conveying systems, pealing ad blistering effect on spray painted surfaces etc. To eliminate these inefficiencies and maintenance problems,-answer is Air Dryer.

TYPES OF AIR DRYING UNITS
Various Designs are available to dry the compressed air. Some use Desiocants while other are based on Refrigeration principle. In Desiccant-Dryers, Activated Alumina/Molecular Sieves are used to remove the moisture. In Refrigerated Type Dryers air is cooled moisture is condensed out. Desiccant type Dryres consume electrical energy and in some designs there is compressed air purge loss. These are recommended only when very very dry air is peeled.

For most of the applications, Refrigerated Dryers are adequate as they provide (-) 20 Deg C Dew Point. If properly maintained, these are the most economical Units.

DEW POINT
Dew Point is measure of moisture in air. It is the temperature at which moisture in air starts condensing. Lower the Dew Point, more dry is the air. Air of (-) 20 Deg Dew Point means that no moisture would condensed in the pipelines if the ambient temperature is more than (-) 20 Deg C. For most industrial Applications, Dew Point of (-) 10 Deg C is generally considered quite satisfactory and this Dew Point is available easily form Refrigerated Air Dryers.

REFRIGERATED AIR DRYER
  1. In small capacities upto 500 NM3/hr we offer Model 1702. It is the simplest and very compact unit consisting of Cylindrical Heat Exchanger with Freon Tubes. Air flows outside the tubes and gets cooled to 3 Deg C temperature. Moisture condenses out and is drained continuously. The out going air is at 3 Deg C temperature with (+) 3 Deg C Pressure Dew Point which is equivalent to approx (-) 20 Deg C atm. Pressure Dew Point.



  2. For larger air capacities, we offer model 2432 for above 500 NM3/hr air flow rates. It is a skid mounted Unit consisting of Air-Freon Chiller, Air to Air pre-Cooler and a Moisture Separator. First air is precooled with ourgoing chilled air to around 25 Deg C and then it is cooled in-a Freon Cooler to (+) 3 Deg C temperature. This reduces refrigeration load of the Unit. Outgoing dry air has (+) 3 Deg C Pressure Dew Point and comes out around 25 Deg C temperature. (+) 3 Deg C Dew Point achievable in refrigerated Air Dryers corresponds to around (-) 20 Deg C atmospheric pressure Dew Point. Still lower Dew Point are not possible from Refrigerated Dryers as moisture condensed woild start freezing on the Freon Tubes if lower Dew Point are tried, (-) 20 Deg C is the best possible Dew Point achievable from Refrigerated Air Dryers.
ECONOMICS
SATYA ENGINEERS refrigerated Dryers provide high performance at lower operating cost than ordinary Refrigerated Dryers.
