Why is sodium hydroxide rather than potassium hydroxide commonly used as the base in the acid elution process for crude oil? Apart from cost issues, what are the advantages of using sodium hydroxide over potassium hydroxide? Another issue is how to address its emulsification phenomenon, and what demulsifiers are effective.

The prices of sodium hydroxide and potassium hydroxide are not on the same level

One is the price issue, and the other is the usage issue; ultimately, it’s because the cost of potassium is high.
