ABSTRACT:
Methods and compositions are disclosed for neutralizing acidic components in petroleum refining units. The neutralizing agent comprises a member selected from the group of dimethylaminoethanol and dimethylisopropanolamine. The neutralizing agent may be added directly to the charge, in a reflux line, or directly to the overhead line of the refining unit. In those instances in which sour crude is to be refined, it is desirable that dimethylisopropanolamine be used in conjunction with the dimethylaminoethanol. The neutralizing agents are added in an amount sufficient to elevate the pH of the condensate (as measured at the accumulator) to within the pH range of 4.5-7.
