Embodiment 1

[0029] A closed metal casing is processed by welding, and an injection hole is reserved on the metal casing. The metal particles are filled into the metal shell, and then the second liquid component is injected into the metal shell. Use a metal stopper of the same material to insert into the injection hole, and make sure that the metal stopper is firmly on the injection hole.

[0030] Both the first liquid component and the second liquid component are mixed by 5 parts of imidazoline derivatives, 80 parts of oleic acid aminoamide, 2 parts of butyl phosphate, and 2 parts of dodecyl primary amine. The product is 1-hydroxyethyl-2-oleyl imidazoline. The mass ratio of the first liquid part to the second liquid part contained in the entire slow-release part is 1:1.

Abstract

The invention discloses a reforming corrosion inhibitor, which is composed of a first liquid component and several slow-release parts; wherein, the first liquid component includes the following components in parts by weight: 5-10 parts of imidazole morphine derivatives, 50-80 parts of oleic acid aminoamide, 1-2 parts of butyl phosphate, 2-4 parts of dodecyl primary amine; The second liquid component inside the metal shell, the composition of the second liquid component is the same as that of the first liquid component, and the metal shell is made of iron metal. The reforming corrosion inhibitor of the present invention can be automatically replenished, thereby prolonging the protection time for the reforming device, shortening the injection frequency of the corrosion inhibitor, and reducing the requirements for the monitoring accuracy of the corrosion inhibition monitoring system; the reforming corrosion inhibitor of the present invention The etchant also has a good effect of inhibiting corrosion.

Description

technical field [0001] The invention relates to the technical field of metal corrosion protection, in particular to a reforming corrosion inhibitor. Background technique [0002] Petroleum reforming process is the process of rearranging the molecular structure of hydrocarbons in gasoline fractions into a new molecular structure under certain conditions. Substances such as hydrochloric acid and hydrogen sulfide produced during the reaction will cause corrosion of the reforming unit. Since the reforming unit operates under high temperature, high pressure and hydrogen environment, once corrosion failure occurs, the consequences will be very serious. Therefore, corrosion measures need to be taken to avoid corrosion damage to the reformer. There are many types of existing corrosion inhibitors, but their corrosion inhibition effects are still not ideal. Moreover, after the corrosion inhibitor is added to the reforming unit, the corrosion of each part of the reforming unit must ...
