XWR-9812 silicone-free antifoaming agent——for delayed coking equipment
Brief introduction
According to the characteristics of foam layer in delayed coking equipment, we developed XWR—9812 silicone-free Delayed coking antifoaming agent:
It is a new kind of silicone-free antifoaming agent, which is made of several active matters.
It is one kind of antifoaming agent , which is designed to control the foam produce by Delayed coking process in the production of petrochemical industry.
It is one kind of non-toxic antifoaming agent, with fast antifoaming speed and long inhibiting time.
Features
It can reduce scale of coke tower greatly and increase coking volume, thus it can increase output of coke, and improve the quality of coke too.
It can improve equipment utilance because it prolongs operational time
he quality of coked light oil is improved because reaction oil gas contains less coke powder
It is extremely compatible with delayed coking materials, thus it doesn't poison the catalysts in subsequent processing.
