Example Embodiment
[0014] Example 1
[0015] 1. Combine 180kg of low alkali value sodium hypochlorite, 60kg of ultrafine sodium silicate and 60kg of HEDP to prepare a deodorant.
[0016] 2. Combine 400kg of low alkali value sodium hypochlorite and 100kg of THPS to prepare a passivating agent.
[0017] 3. Compound the above-mentioned 300kg deodorant, 500kg passivator and another 200kg THPS to prepare the deodorant passivation double-effect cleaning agent for the oil refining device of the present invention.
[0018] The available chlorine in the low alkali value sodium hypochlorite is 10%, the alkali concentration is 0.2%, the potassium pyrosulfate is 2.5%, and the alkaline corrosion inhibitor is 2.0%;
[0019] After roughly calculating the inner surface area of the device to be cleaned, press 18kg / m 2 The amount of the cleaning agent of the present invention is diluted with water. Add the diluted cleaning agent to the additive tank, and connect the oil refining unit to be cleaned to form a ...
