General information
The oil-gas separation defoamer ZX-XP-03 is a chemical reagent used in processes such as delayed coking, oil-gas separation, oil-water separation, asphalt plant defoaming, and BTX extraction defoaming. This product is designed based on the water production characteristics of condensate oil wells and the requirements of gathering gas processes. It is particularly suitable for oil-gas separation in the oil production process dominated by natural gas.
This defoamer can quickly eliminate foam and maintain long-lasting foam inhibition even at low concentrations. It has high-temperature resistance and is suitable for a wide range of oil products.
The oil-gas separation defoamer ZX-XP-03 has the characteristics of fast defoaming, long-lasting foam suppression, low dosage, good stability at high temperatures, and good compatibility with solvents.
The defoaming rate can reach ≥ 95%. It has a very good foaming-inhibiting effect on both heavy and light oils, and is a highly efficient defoaming agent.
Composition
This product is composed of special non-ionic surfactants and hydroxyl compounds.

Application
Site Application
The oil-gas/water separation defoamer is mainly applicable to:
- Delayed coking, oil-gas separation, oil-water separation;
- Defoaming in asphalt plants, defoaming for emulsified asphalt, defoaming for asphalt, defoaming in BTX extraction, defoaming in vacuum distillation;
- Transportation of crude oil or refined oil;
- Defoaming in other crude oil extraction processes.
Usage Method
The oil-gas separation defoamer ZX-XP-03 can be added after the formation of the foam or incorporated as an anti-foaming component into the product.
The addition amount of the oil-gas separation defoamer is usually 0.1% to 0.8% (i.e., 1000 to 8000 ppm), and the specific amount is determined by the customer through experimentation based on the specific circumstances.
For some specific processes (such as delayed coking), the recommended addition amount can be as low as 10-50 ppm.
The addition methods include directly adding the foaming liquid or diluting it before adding. When using it, it is generally recommended to first dilute the oil-gas separation defoamer with petroleum solvents (such as kerosene, xylene) at a ratio of 1:10 to 1:30, and then use a metering pump to add the diluted liquid to the foaming system.
In this way, the oil-gas separation defoamer can quickly disperse into the foaming system and better exert the defoaming effect. When used in high-temperature processes such as delayed coking, steam can be injected at the defoamer injection point to prevent high-temperature residues from entering the injection point and causing coking.
