BRIEF WRITE UP EQUIPMENT


1. INTRODUCTION

This document describes the major components of the PSA Oxygen

Generation System and its associated components. The design,

materials and workmanship incorporated in the construction of Oxygen

Generators make them capable of giving long, trouble-free service.

PSA Oxygen generators produce gaseous oxygen from compressing

atmospheric air on site and offer a cost-effective, reliable and safe

alternative to traditional oxygen gas supplies such as cylinders or

cryogenic liquid. The design is made for round the clock 24/7

operation. Each generator is equipped with automatic start & stop


function, enabling the generator to start and stop automatically

according to the consumption.

ADVANTAGES: No Raw Material: There is no Raw Material required to

produce high purity grade Oxygen, as plant uses air from atmosphere

to separate oxygen from processed air.

Quality & Durability: Each Generator is Analyzed & Tested over Latest

CFD Software for dynamic loading in order to ensure Quality product

with SMART Productivity of Oxygen Gas.

Oxygen on demand: Production of oxygen at the specified flow and

purity for a short time of demand by simple push button.

Energy efficiency: The PSA process is characterized by low specific

energy consumption. Easy partial load operation PSA Generators are

fully automatically adjusted to the actual product flow requirements

and operate in an energy-saving partial load mode.

Skid Mounted: Generator is supplied Pre-piped over a platform in

order to cuts down installation time, plant is supplied in ready to use

and plug and play condition.

High availability: PSA Generator provide supreme availability by using

reliable components such as Screw Compressors proprietary switching

valves.

Fully automatic operation: The PLC based control system with its

sophisticated software controls purity and flow by adjusting the cycle

time automatically.

Oxygen generator being supplied is based on a patented

implementation of the PSA (Pressure Swinging Adsorption) technology,


a static separation of air gases thanks to a specific molecular sieve

that adsorbs Nitrogen under pressure.

The Oxygen generator is mainly composed of 2 separation vessels

filled with molecular sieve (zeolites) absorbers. As compressed air

pressurizes one vessel, the Nitrogen is progressively retained by

the molecular sieve and the Oxygen goes straight to the outlet

of the generator. When the vessel is approaching Nitrogen

saturation, the process switches to the second vessel and the

adsorbed Nitrogen in the first vessel is released into the atmosphere.

The cycle is then repeated under computerized control in order to

produce high purity Oxygen continuously.

2. SYSTEM DESCRIPTION

Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other

trace gases. Oxygen generation systems separate this oxygen from

Compressed Air through a unique process called Pressure Swing

Adsorption. (PSA).


The Pressure Swing Adsorption process for the generation of

enriched oxygen gas from ambient air utilises the ability of a synthetic

Zeolite Molecular Sieve to absorb mainly nitrogen.

While nitrogen concentrates in the pore system of the Zeolite, Oxygen

Gas is allowed to pass through as a product.

Oxygen generation plants use two Pressure Vessels filled with Zeolite

Molecular sieve as adsorbers.

As Compressed Air passes up through one of the Adsorbers, the

molecular sieve selectively adsorbs the Nitrogen. This then allows the

remaining Oxygen to pass on up through the adsorber and exit as a

product gas.

When the adsorber becomes saturated with Nitrogen the inlet airflow

is switched to the second off line adsorber. The first adsorber is

regenerated by desorbing nitrogen through De-Pressurisation and

purging it with some of the product oxygen. The cycle is then repeated

and the pressure is continually swinging between a higher level at

adsorption (Production), and a lower level at desorption

(Regeneration).

In Pressure Swing Absorbtion technology Our engineers have

dedicated special attention to the adsorber vessel design in order to

avoid fluidization of the psa molecular sieve bed during the entire

adsorption and desorption process and under any possible working

condition of the PSA Generators.


PSA Generators are designed for Dynamic Load as PSA generators

operate in cycles and each vessel pressure and depressurize in less than

3 minutes. This Pressure fluctuation creates tension that must be

considered during Designing of Pressure Vessels, Our pressure vessels

are designed for dynamic pressure loading and are designed to last

minimum 2 million pressure cycles

Extensive CFD simulations and running tests have been performed in

order to remain distant from the physical fluidization limit for each

adsorber vessel size and under all process circumstances.

This break-through made it finally possible to develop a compact,

highly efficient and truly flexible PSA generator which can produce 90%

± 2% Oxygen Generator.

Advantages of PSA Generator over Cryogenic Oxygen Generator

PSA Oxygen Generator Cryogenic Oxygen Generator

Investment cost in PSA Generator

is comparatively lower. Cost of a

PSA plant is typically less than half

of that of an equivalent cryogenic

plant

Investment cost of Cryogenic

Oxygen Generator is very high.

Typically, it is more than double

that of an equivalent PSA plant.

PSA Oxygen generator’s start-up

time is only 5-minutes. Therefore,

depending on Oxygen demand,

Generator can be switched ON &

switched OFF very conveniently.

Cryogenic plant startup time is

around 12 to 16 hours for start-

up. Therefore, Cryogenic Oxygen

plant cannot be switched ON &

switched OFF very frequently.


PSA Oxygen generator is very

simple & does not need even

dedicated manpower. It keeps

working round the clock without

any supervision.

Cryogenic Oxygen Plant is very

large equipment requiring lot of

sophisticated controls and

maintenance cost is high. Also

dedicated man-power is needed

to monitor and operation of

Cryogenic Oxygen plant.

PSA generator is very compact

size unit

Cryogenic plant requires a very

large size building & bigger

footprint size.

PSA Oxygen gas can be stored in

a standard Economical tank.

Cryogenic Oxygen is to be stored

in a vacuum insulated double

walled Tank. Cost of this Storage

tank is on higher side.

3. WIRING

All wiring will conform to Australia Standards wiring rules.

All wiring (excluding instrument pairs) will be minimum .75mm2

All wiring on the package will be LSOH.

All Panel Control 24 Voltage wiring will be 0.75mm2 single core

flex

All wiring external to the panel will be 1.5mm2 stranded copper

No more than two wires per terminal

All cables between Junction boxes will have cable numbers both


ends

4. RELIABILITY

PSA oxygen generation systems are extremely reliable. Systems are

designed to run 24 hours days 365 days a year with very little operator

Intervention. They are lightweight compared to other technology, are

very rugged and durable.

5. ADVANTAGES OF DESIGN

PLC Control of all process valves and alarm functions

All Electrically sensitive equipment is individually fuse protected

Superior Internal Screen design allows for less stress on

Molecular sieve

Superior Air Filtration Package.

Air Treatment Package mounted on a common skid for ease of

installation. All Filters have D/P Gauges

PSA Skid makes for smaller footprint and easier installation Easy

access to components for easier Maintenance.

Bacterial Filter 0.01 Micron which can be regenerated in an

Advantages of our design is the type of Valves we use in our systems.

Solenoid Valves: We do not use standard Solenoid type valves which

have a short service life due to the high cycle nature of a PSA Solenoid

valves have a thin internal diaphragm which will eventually crack due

to the operation of the valve.


Oxair - use a true Air Pilot Operated Actuated Process Valve.

The Valve has a heavy plunger actuator inside the valve which will give

many, many years of trouble free operation. (See Below)

Small - Process Valves: We have systems that are well over 8 year’s old

still operating with the same valves.

Check Valves: Because of the type of valve we use on our systems it

has eliminated the need to use check valves on our systems. The valves

are 100% Bubble tight shut off in either direction. Check Valves do not

have a long service life and will eventually start to by-pass causing a

loss of purity.

PSA Piping System: Oxair does not use any flexible piping on our PSA

systems. Oxair PSA Piping systems are 100% leak free. All piping is

made from the unique Stainless Steel Press-fit design. Not only does it

not leak it is clean and looks good.
