Patent ID: 8882995

Claim:
Process for predicting and reducing the corrosivity of a hydrocarbonaceous mixture comprising crude oil and/or condensates and water, which process comprises: (i) taking a sample from the hydrocarbonaceous mixture comprising crude oil and/or condensates and 0.1% to 2.0% by weight water and extracting water-soluble carboxylic acids comprising non-aromatic acids having from 1 to 7 carbon atoms from the sample with the help of an aqueous solution, (ii) subjecting the extracted water-soluble non-aromatic carboxylic acids to chromatography, (iii) calculating the concentration of water-soluble non-aromatic carboxylic acids in the hydrocarbonaceous mixture based on the chromatography results, and (iv) reducing the concentration of water-soluble non-aromatic carboxylic acids in the hydrocarbonaceous mixture based on the calculated concentration of water-soluble non-aromatic carboxylic acids in the hydrocarbonaceous, thereby reducing the corrosivity of the hydrocarbonaceous mixture.
