METHODS FOR CHARACTERISING AND MINIMISING THE CORROSIVE EFFECTS OF AN OIL AND OIL PLANT MAKING IT POSSIBLE TO MINIMISE THE PROBELMS OFCORROSION

摘要

The invention relates to a method of characterization of one petroleum, wherein the petroleum is placed in contact with a metal part, and which includes the following steps:i. Modifying the water content (W) of the petroleum,ii. Measuring the corrosion (CR) of said metal part by the petroleum whose water content (W) has hence been modified,iii. Building, by reiterating several times the two previous steps (i, ii), a database containing a plurality of different values of water content (W) of the petroleum and a plurality of values of corrosion (CR) each corresponding to one of said values of water content (W),iv. Determining, by processing said database, an optimum value or an optimum range of values of water content (M_W) of the petroleum for which the corrosion of the metal part shows a minimum value (M_CR).;Problems of corrosion in the petroleum exploitation plants.
