Problems solved by technology

However, most of the tetrakis hydroxymethyl phosphorus sulfate used in the market to clean ferrous sulfide is to use a single tetrakis hydroxymethyl phosphorus sulfate solution for cleaning work, such cleaning effect is low, and the consumption of tetrakis hydroxymethyl phosphorus sulfate Larger, can not get the best ferrous sulfide cleaning effect

Abstract

The invention discloses a new type iron-biting bactericide. The new type iron-biting bactericide comprises tetrakis hydroxymethyl phosphonium sulfate, water, sodium salt of diethylenetriamine penta and sodium hydroxide. The new type iron-biting bactericide disclosed by the invention has the beneficial effects that according to the iron-biting bactericide prepared by the formula and by the mixing effect of the tetrakis hydroxymethyl phosphonium sulfate and the sodium salt of diethylenetriamine penta, the dissolution rate of the ferrous sulfide is increased, and the consumption of the tetrakis hydroxymethyl phosphonium sulfate is reduced, so that the best ferrous-sulfide treating effect is achieved.

Description

(1) Technical field [0001] The invention relates to the field of ferrous sulfide treatment, in particular to a novel ferric phagocytic bactericide. (2) Background technology [0002] At present, ferrous sulfide is a very common substance in oil storage tanks and oil pipelines of refineries. With the increase of the service time of the oil storage tank and the action of the corrosive medium, the anti-corrosion coating on the inner wall of the oil storage tank will be partially peeled off, and the iron under the coating will be exposed, and the main corrosion products formed after being corroded are Iron oxide, iron hydroxide, and ferric oxide may react with the humid hydrogen sulfide gas in the storage tank to convert to ferrous sulfide in the absence of oxygen. The ferrous sulfide produced due to corrosion is usually on internal components such as storage tanks or trays. If these flammable ferrous sulfides are not properly handled before maintenance, it is easy to cause spo...
