Performance characteristics
This product is a kind of polyether compound as the main defoaming material, supplemented by other additives. It is a low-silicon defoaming agent and is mainly used for the production of delayed coking. of bubbles. This defoaming agent has low silicon content, low volatility and good high temperature stability. It can avoid the increase in silicon content in coked distillate oil due to the use of defoaming agents, which in turn will have adverse effects on the downstream processing technology and avoid downstream hydrogenation catalysts. Poisoned.
Application
In the delayed coking unit, a large amount of oil and gas produced by high-temperature cracking of the raw oil will easily foam in the coke tower. As the coke layer rises, foam will rush out of the top of the tower, causing coking and blocking of the oil and gas pipelines, and increasing the amount of coke powder carried in the oil and gas, affecting the normal operation of the fractionation tower and the processing capacity of the coke tower. A large amount of foam also seriously affects the processing capacity and product quality of the coking unit. Therefore, defoaming agents need to be used to reduce the height of the foam layer and inhibit the generation of foam. The delayed coking defoaming agent is a low-silicon defoaming agent with relatively good defoaming performance developed based on the characteristics of the foam layer of the delayed coking device. Mainly used in desulfurization and decarbonization systems for fertilizer production and delayed coking processes in refineries.
Usage and dosage
The foam is stored in the coke tower. As the viscosity of the material in the coke tower increases and solids are formed, a stable foam layer will be produced. Through the correct use of defoaming agents, the height of the foam layer can be reduced, preventing top overflow, and minimizing the amount of heavy oil and coke powder carried by the oil and gas leaving the tower. It is usually added from the top of the coke drum, and is often injected with light gas oil. The main purpose of carrying oil is to keep the filling line clean and help the silicone oil be distributed on the foam.
The amount of foaming agent should be 0.2 times, and the defoaming agent must be diluted with kerosene or diesel components in advance.
The method of use must be determined based on experiments.
