PARAT IMT

A steam unit that consumes water requires oxygen removed from the 
incoming water. Deoxygenation with the use of steam significantly 
reduces the need for chemicals, and has the advantage of heating the 
feed water. A PARAT degasser will ensure a long lifetime for 
the steam system.

The PARAT degasser/feed water tank has all necessary connections for 
pumps, chemical dosing, water sampling, etc. Condensate return, 
chemical dosing and steam heating are submerged under the 
water surface. The steam injector is located on the cleaning 
hatch for maintenance.

The cleaning hatch is conveniently located to facilitate purging the 
bottom of the tank. Steam heating is located with in relation to suction 
nozzles for pumps so as to avoid cavitation. The deaerating tower is 
located for optimum steam utilization. The steam is released at the 
bottom of the tank, removing oxygen by diffusion. Cold water is supplied 
to the tower, where air is released from the pressure deaerator. 
It runs over strainer plates, giving the water a large surface area, thus
facilitating additional deoxygenation and better condensation of 
the steam. This ensures maximal release of air as opposed to steam.

Thus a PARAT degasser is an economical solution for deoxygenation 
in a steam unit.
