  • Process for treatment of petroleum acids with ammonia
    Patent number: 6258258
    Abstract: The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.

  • Process for reducing total acid number of crude oil
    Patent number: 5891325
    Abstract: The instant invention is directed to a process for reducing organic acids in petroleum feeds containing organic acids comprising: (a) thermally treating a petroleum feed containing organic acids in a thermal reaction zone comprising a plurality of stages in series, at a temperature and pressure sufficient to decompose at least a portion of said organic acids while sweeping said plurality of stages with an inert gas, to produce a volatile organic acid containing hydrocarbon fraction and a non-volatile hydrocarbon fraction; (b) treating said volatile hydrocarbon fraction to neutralize at least a portion of said organic acids therein and to produce a treated volatile hydrocarbon fraction; (c) collecting said non-volatile hydrocarbon fraction from said thermal reaction zone; and (d) blending said treated volatile hydrocarbon fraction of step (b) with said collected non-volatile hydrocarbon fraction.
