Abstract
Improved methods for removing arsenic from starting liquid hydrocarbons are provided which comprise contacting the hydrocarbons with a composition containing a triazine component and a glycol ether component, allowing the composition to react with the arsenic to create a treated hydrocarbon fraction and an arsenic-rich fraction, and separating the treated fraction from the arsenic-rich fraction. Preferably, the treating composition also includes an alcohol, and is used at a level of from about 1-10,000 ppm.
