Abstract

The invention discloses a hydrogenation scale inhibitor. The hydrogenation scale inhibitor is prepared from components in percentage by weight as follows: 10%-30% of a clearing agent, 5%-10% of an antioxidant, 0.5%-2% of a passivator, 0.5%-2% of an antirust agent, 1%-2% of a cosolvent and 50%-70% of an organic solvent, wherein the clearing agent is Mannich amine. The invention further provides a preparation method of the hydrogenation scale inhibitor. According to the preparation method, the raw materials are taken in a ratio of the components and are mixed and stirred uniformly at normal temperature and normal pressure. Mannich amine is adopted to replace other amines, so that the hydrogenation scale inhibitor is better in high-temperature stability, excellent in scale inhibition performance and low in cost and has a better cleaning function for high-temperature parts such as an air inlet valve, a nozzle and the like, and tail gas emission can be reduced.

Description

technical field [0001] The invention relates to a scale inhibitor, in particular to a hydrogenation scale inhibitor used in a hydrocracking unit and a preparation method thereof. Background technique [0002] At present, as the quality of crude oil becomes heavier and worse, the oil processing conditions become more stringent. The problem of fouling in heat exchangers and pipelines of hydrocracking units is becoming more and more serious, which affects the energy consumption and normal operation of the units. When the fouling phenomenon of the high pressure heat exchanger is serious, the heat transfer effect shows a downward trend. If the fouling situation continues to deteriorate, it will also cause blockage of pipelines or equipment, forcing the device to stop cleaning, which will not only shorten the operating cycle of the device, but also bring hidden dangers to the safe production of the device. [0003] Hydrogenation antiscalant is a multifunctional compound additive,...
