Oxygen is Drawn to a Magnetic Field – “Paramagnetic”

One of the properties of oxygen is that it is “paramagnetic” or

drawn to a magnetic field. The picture above shows liquid Oxygen

suspended in a magnetic field.

Thermoparamagnetic Oxygen (TPM) Sensor

• Oxygen’s paramagnetic property causes it

to be attracted to a magnetic field.

Heating the gas cases less attraction of

Oxygen to the magnetic field.

• The sensor has a strong magnet and two

pairs of heated thermistors. Gas

movement causes “magnetic wind” which

cools the wind generating thermistor.

• The resistance of the thermistors are

proportional their temperature. A bridge

circuit provides a voltage proportional to

the oxygen concentration

“Dumbbell” Type Paramagnetic O2 Sensor

• Two nitrogen filled glass spheres

are suspended within an electro-

magnetic field.

• Oxygen attracted into the

magnetic field displaces the

nitrogen filled spheres, causing

the suspended spheres to

rotate.

• The mount of current it takes to

restore the spheres to a “null

position” is related the oxygen

concentration. It is controlled by

the amount of light received by a

photocell.

Inerting Chemical/Fuel Storage

The head space of chemical and fuel

storage tanks are often purged with

an inert gas to assure that the O2

concentration below the LEL (Lower

Explosion Level)

Ambient air contains 21% O2

The XMO2 is rugged, explosion proof

and has no moving parts .

10

Sampling System For Inerting

11

Alfa Laval/Aalborg/Smit Gas Inerting utilizes the products of combustion for inerting

fuel and chemical tankers.

Shipboard inert blanketing gas is produced by combusting fuel utilizing seawater to

cool chamber “wash” the product of combustion which is mainly N2 & CO2. The

combustion gas is cooled below the dew point to condense water. The dry clean gas

is used to blanket fuel can chemical tankers

O2 Measurement for Tanker Inerting

12

Oxygen Measurement in Vapor Recovery Systems

Aeron located in

Louisville, KY is an OEM

of vapor recovery units

To comply with

environmental

regulations and to yield

more available energy

whenever a tank (barge

or ship) is loaded vapor

recovery units are used

and O2 transmitters are

used

13

XMO2 for Plastic Resin Production

Background: Sabic produces a variety of

engineered plastics including Lexan & Noryl.

Application: Oxygen control in polymer

reactor vessels. %O2 kept under 9% (LEL).

Typically maintaining 4%.

System sold: XMO2/TMO2D with Sampling

system. Sample system includes filter,

eductor (to pull sample) and solenoid for N2

(zero) and Air (21% O2) gases.

• Past experience with XMO2.

• No moving parts on TPM

technology… .reliable for process

environment

• Turnkey sampling system

• Digital interface for automated zero and

span calibration (no manual adjustment

needed)

14

Oxygen Analyzers for Floating Platform

Stainless Steel body transmitters were

used for Kaombo Deep Water Offshore

Oil Platform.

Two FPSO units, each with a treatment

capacity of 115,000 barrels per day, will

process, store and offload the production.

22

Arc welding is process that utilizes

electricity to produce the weld.

A constant-current welding power

supply produces electrical energy,

which is conducted across the arc

through a column of highly ionized gas

and metal vapors known as a plasma.

The weld area is protected from

atmospheric contamination by an

inert shielding gas (Argon or Helium).

The “shield gas “ must be devoid of

oxygen and H2O
