Crude Oil Dechlorinating Agent
At present, the electric desalting technique in oil refinery can only remove alkali or alkaline earth metal chlorides, but could not remove organic chlorides resulted from organic chlorine additive which is added during oil recovery process. It is known that during distillation organic chlorides can decompose partly and enter the top fraction to corrode equipment.
Without any change of the technique, this problem can be solved by adding the Dechlorinating Agent into crude oil before electric desalting. With the presence of the product, chlorine element from organic chlorides could be transferred to water phase by molecular interaction to achieve an effective removal of organochlorine.
The product applies to all types of crude oil for organochlorine removal.
Appearance Light yellow liquid
PH value ≥ 11
In order to achieve high performance, the product is suggested to be added separately at different levels of electric desalting through anticorrosion metering pump. The added volume depends on the content of organochlorine in crude oil as follows:
15-20 ppm if the content of organochlorine in crude oil is less than 10 ppm;
20-40 ppm if the content of organochlorine in crude oil is between 10-60 ppm;
40-60 ppm if the content of organochlorine in crude oil is between 60-100 ppm.
Attention: the product could not be employed with decalcifying agent at both the same time and same level of electric desalting, but could be added separately.
This product is packed in plastic barrel with the weight of 200 kg/ barrel.
When the addition amount of Dechlorine Agent is 20-40 ppm (according to the raw material quantity), under this condition, after the electric desalting,the organic chlorine elimination rate is not less than 40%, and meanwhile the total chlorine of the electric desalting drainage has been increased, while the total chlorine in the top drainage of the three towers decreased.
