PRODUCT DESCRIPTION
No-silicon high-effect defoamer is used for delayed coking unit. It can reduce the foam layer highness, extend coking time, decrease coke powder taken, protect exchanger and cold device and radial pump, put an end to catalyser poisoning in the subsequent hydrogenation unit. It can also reduce coke powder sediment in the volatilization line and the fractionating tower so that to prolong safe production period.
FEATURES
(1) No silicon element, harmless to catalyst of hydrogenation unit.
(2) Less dosage, long using period, stable chemical composition.
(3) Fast defoaming speed and lasting antifoaming nature.
(4) No corrosion effect to metal.
APPLICATION METHOD
(1) Add it to coking tower from the top
(2) Adding volume is about 50-75ppm.
(3) Added continuously through pump.
NOTICE
(1) Stored in cool, dry place and keep away from fire, handle with care.
(2) Used according to actual conditions of the factory
