Recommended Usage

It is recommended that volume pump metering be used to optimize the addition during continuous or semi-continuous operation.

The general addition range is 0.5-100ppm. For different defoaming systems, it is recommended to carry out experiments in advance to achieve the best defoaming effect and to control the appropriate amount of defoaming.

For applications such as delayed coking, it is recommended that the evaluation be carried out in the range of 40-80 ppm.

For applications such as oil and gas separation, it can be added between 1 and 10 ppm.


RJ-O102T is available in 25kg, 50kgs or 200kg plastic drum or other packing on request.
