Refining equipment in the refining of sulfur content greater than 05%, acid value greater than 05mgKOH / g crude oil, the high-temperature parts by S, H2S and naphthenic acid strong corrosion. In the role of erosion, oil flow at the corner of the corrosion is particularly serious, often leading to premature failure of equipment. In view of this situation, the causes of high temperature erosion corrosion were analyzed and the protective measures were put forward:
(1) to reduce high temperature sulfur and acid corrosion, high and low acid mixed with oil refining, the crude oil acid value down to 05mgKOH / g or less;
(2) to reduce the role of the erosion of the oil flow in the design to ensure that the fluid path is streamlined, reducing the turn, change diameter and change to keep the surface smooth little dead, the maximum reduction of eddy current;
(3) welding pipeline with argon arc welding base, reducing welding scar;
(4) the use of corrosion-resistant materials.
I research and development in the production of refined oil refining equipment has been adhering to the rigorous attitude, so we can rest assured to buy today for the maintenance of its high temperature method, we hope to be able to help.
