Discuss issues regarding crude oil pretreatment and electrical desalting~~
Thread Content
Let’s discuss the salt and water content of the crude oil in each factory after electrical desalting. ? The water content of our stripped crude oil is ≤0.5% and the salt content is ≤3mg/L.
After dehydration, the water content of crude oil is ≤0.2%-0.5%, which is generally controlled to be trace, and the salt content is ≤5mg/L.
After dehydration, the water content of crude oil shall not be greater than 0.3%, and the salt content shall not be greater than 3 mg/l.
It is required that the water content of the oil after removal is ≤0.2% and the salt content after removal is ≤3mgNaCl/L. The dosage of pharmaceuticals is less than 20ppm
Is there still room for decline? Is there any significance in continuing to reduce salt and water content? :o
It is required that the water content of the oil after removal is ≤0.2% and the salt content after removal is ≤3mgNaCl/L. The dosage of pharmaceutical is 20~.35ppm
It is required that the water content of the oil after removal is ≤0.3% and the salt content after removal is ≤15 mgNaCl/L. The dosage of demulsifier is 40ppm
After crude oil is removed, the water content shall not be greater than 0.3%, and the salt content shall not be greater than 3mg/l.
The salt content is not more than 3mg/l, and it contains water.: trace
The general anti-corrosion requirement is that the salt content should not be greater than 5 mg/l. For those with catalytic post-processing technology, the salt content should not be greater than 3 mg/l. Of course, the smaller the better, but it depends on the desalting ability, the type of crude oil, and the screening of demulsifiers. There must be a comprehensive consideration. If there are various types of crude oil, it is best to have a stronger electric desalting ability. As for the water content, it mainly affects safety and energy consumption.
Salt content after removal: Less than 3mg/l, water content: The trace is ultrasonic demulsification without demulsifier.
