摘要：

The salt content of a crude oil consists of salts dissolved in the water, which are dispersed within the produced crude. This study has been done to find the optimum conditions for desalting and dehydration of two types of Iraqi crude oil (Naft Khana crude and Basra crude from the Iraq strategic pipeline), which were provided from the Daura refinery in Baghdad. Naft Khana crude oil is lighter than Basra crude oil and has higher API gravity and it is relatively easy to desalt. Also, Naft Khana crude oil has a salt concentration higher than Basra crude oil. The optimum experimental conditions for improving desalting/dehydration process were 7 vol% ethylamine dosage, 100 degrees F crude oil temperature, 20 vol% adding fresh water, and 30 min settling time. Basra crude oil required a high washing water ratio to increase the rate of water droplet settling in the desalter and the dilution efficiency of salts in crude oil.
