Abstract

The invention relates to a high-concentration vanadium inhibitor composition and a preparation method thereof. The vanadium inhibitor composition is a suspension system and comprises the following raw materials by weight percentage: 50-70% of magnesium powder, 20-40% of a solvent, 2-6% of glacial acetic acid, 3-18% of a dispersant, 1% of manganese oxide, 1% of copper oxide and 3-15% of an adjuvant. The preparation method of the high-concentration vanadium inhibitor provided by the invention is simple in process; and the obtained vanadium inhibitor has the advantages of high efficacy, high concentration, easy mixing, good fluidity, no adhesion to container wall and good stability, thus can be stored for a long time, is difficult to agglomerate and crust when encountering with water or air, is convenient to be stored, is mainly adaptable to a heavy oil fired boiler, and can effectively inhibit the corrosion caused by S, V, Na and other harmful components in the heavy oil.

Description

technical field [0001] The invention relates to a heavy oil additive, in particular to a high-concentration vanadium inhibitor composition and a preparation method thereof, which is mainly suitable for boilers burning heavy oil and can effectively inhibit corrosion caused by harmful components such as sulfur, vanadium and sodium in heavy oil. Background technique [0002] In combustion chamber boilers burning heavy oil, corrosion is often caused by substances such as sulfur, vanadium, and sodium in fuel oil, such as low-temperature corrosion caused by sulfuric acid and high-temperature corrosion caused by vanadium compounds. High-temperature corrosion occurs in the superheated tube of the boiler, the wall of the combustion chamber and other parts with high temperature, which is caused by vanadium pentoxide (V 2 o 5 ). V 2 o 5 The melting point is about 670°C. Below this temperature, vanadium pentoxide is solid and will not adhere to the pipe wall, but when it exceeds thi...
