Title:
A METHOD FOR REMOVING PETROLEUM ACID FROM ACID-CONTAINING HYDROCARBON OIL
Document Type and Number:
WIPO Patent Application WO/2006/079287
Kind Code:
A1
Abstract:
A method for removing petroleum acid from acid-containing hydrocarbon oils involves heating the acid-containing hydrocarbon oil to 470-580 degree C, feeding the acid-containing hydrocarbon oil into a reactor, retention for sufficient time under the reactor’s pressure,then feeding the oil and gas from the reactor into the fractionating tower and fractionating them to gas, naphtha, diesel, wax and recycled fraction. The method can make use of the delayed coking equipment to dispose of the acid-containing crude oil and other materials, therefore is simple, economical and continually deeply remove the petroleum acid from acid-containing hydrocarbon oil.
