Q & A > Question Details
While buying and processing Eagle Ford crude oil from Texas, a large amount of methanol was discovered in Light Naphtha (About 700 ~ 800 ppm). Methanol was expected to be mostly removed from the Desalter, but after checking the samples at the front and rear of Desalter, the reduction rate was around 10%. The Desalter temperature and pressure conditions have been checked, but the phase may not be changed. Can you explain why methanol is not removed?

We are aware of application where water is injected in crude oil (100 F) to remove methanol (more than 50% removal efficiency), We do not have reference at desalter conditions.
