This is the main component that removed in the deaerator
and characterized by the molar concentration and the partial pressure of oxygen in the atmosphere.
A pressurised deaerator
is one way to meet the requirements of BS EN 12953 Part 10.
7) Effective deaeration of coatings can only occur when the defoamer or deaerator
is active in the bulk of the coating liquid as well as at the surface.
Unlike most conventional defoamers which are active only at the coating of the surface, Airase 8070 deaerator
is effective in eliminating microfoam, a major problem faced by low-VOC waterborne formulators, and reducing pinholes and craters in coating film to improve gloss, depth of image among other aesthetical properties said the company.
Both pumps have a 1-inch discharge recirculation line that provides a minimum continuous flow of 10 percent (about 30 gpm in this case) back to the deaerator
to assure against a "no flow" condition inside the pump when the steam drum level control valve goes automatically closed.
Spacers of 200 and 300 mm length are available which can be used individually or in combination to vary the length of the deaerator
Breakbulk carrier Conveyor Logistics has completed the delivery of a boiler drum, deaerator
and stator assembly for Bangladesh's Barapukuria power plant.
SPIRAX SARCO has launched a pressurised deaerator
system that Is said to reduce the dissolved oxygen content of boiler feedwater to virtually nil without chemical treatment.
Evonik has launched Tego Airex 921, a deaerator
that has been designed specifically for UV-curable printing inks and coatings for food packaging.
Tego Airex 950 is a polyether siloxane copolymer and Tego Airex 955 is a silicone-free deaerator
There are several quick and easy lab screening tests that help the formulator find the right defoamer or deaerator
