Disclosed is a method of removing organic acids from crude oil using a gas hydrate inhibitor and a catalyst in crude oil production facilities or oil-refining facilities, in which organic acids can be removed from crude oil by reacting the crude oil with mono-ethylene glycol (MEG), di-ethylene glycol (DEG), tri-ethylene glycol (TEG), methanol or derivatives thereof, as a gas hydrate inhibitor in the presence of a tungstophosphoric acid (TPA) catalyst, whereby the acidity of the crude oil can be lowered by 93% or more, and no catalyst deactivation occurs because magnesium (Mg)-based catalysts are not used. Furthermore, a continuous process is achieved in such a manner that the gas hydrate inhibitor and the catalyst are not discarded but are collected from the crude oil from which organic acids have been removed, and are thus recycled, thereby realizing environmentally friendly, economical and efficient removal of organic acids from crude oil.

Disclosed is a method of removing calcium from a hydrocarbon fraction using an extraction agent including 2-oxopropanal or derivatives thereof, the method including (S1) adding a hydrocarbon fraction with an extraction agent including 2-oxopropanal or derivatives thereof to give a mixture, (S2) converting an oil-soluble calcium compound into a water-soluble calcium compound by reacting the hydrocarbon fraction with the 2-oxopropanal or derivatives thereof, and (S3) removing the water-soluble calcium compound.
