The crude oil in the oil residue separator should control the proportion of brine. If too much water is added, the filtered oil will still contain water, which is easy to rancidity. If less water is added, the dephosphorization is not complete and the crude oil is not clean.

Hot-pressed crude oil is mixed with 1- 1.5% hot brine, and the oil-brine ratio is generally 1: 100. Adjust the amount of brine added according to the actual situation of crude oil and try several times, which is near this range.

Because the phosphorus contained in crude oil will cause osteoporosis and other diseases to human body, the first item in the national oil standard is the limitation of phosphorus index content. The purpose of adding salt water is to dephosphorize crude oil. The general principle is H2O. NaCl (brine) reacts with phosphorus salt to produce double salts Na2P5O (sodium phosphate) and H2 = (hydrogen). Adding salt water makes the fine particles absorb more water, increase their specific gravity and facilitate separation.
