Embodiment 1
[0015] 1. Mix 180kg of low alkali value sodium hypochlorite, 60kg of ultra-fine 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 passivation agent.
[0017] 3. The above-mentioned 300kg deodorant, 500kg passivator and another 200kg THPS are compounded to prepare the double-effect cleaning agent for deodorization and passivation of the refining unit of the present invention.
[0018] Available chlorine in the low alkali value sodium hypochlorite is 10%, alkali concentration is 0.2%, potassium pyrosulfate is 2.5%, and alkaline corrosion inhibitor is 2.0%;
[0019] After roughly calculating the inner surface area of the device to be cleaned, use 18kg / m 2 The amount of cleaning agent of the present invention is diluted with water. The diluted cleaning agent is added to the dosing tank, and the refining unit to be cleaned is connected to a temporary pipeline to form a circulat...
Embodiment 2
[0022] 1. Mix 195kg of low alkali value sodium hypochlorite, 65kg of ultra-fine sodium silicate and 65kg of HEDP to prepare a deodorant.
[0023] 2. Combine 520kg of low alkali value sodium hypochlorite and 130kg of THPS to prepare passivation agent.
[0024] 3. Compound the above-mentioned 325kg deodorant, 650kg passivator and 227.5kg THPS in addition to prepare the deodorizing passivation double-effect cleaning agent for oil refinery of the present invention.
[0025] Available chlorine in the low alkali value sodium hypochlorite is 8%, alkali concentration is 0.08%, potassium pyrosulfate is 2.5%, and alkaline corrosion inhibitor is 1.8%;
[0026] After roughly calculating the inner surface area of the device to be cleaned, use 10kg / m 2 The amount of cleaning agent of the present invention is diluted with water. The diluted cleaning agent is added to the dosing tank, and the refining unit to be cleaned is connected to a temporary pipeline to form a circulation system. A...
Embodiment 3
[0029] 1. Mix 168kg of low alkali value sodium hypochlorite, 56kg of ultra-fine sodium silicate and 56kg of HEDP to prepare a deodorant.
[0030] 2. Combine 320kg of low alkali value sodium hypochlorite and 80kg of THPS to prepare passivation agent.
[0031] 3. Compound the above-mentioned 280kg deodorant, 400kg passivator and another 180kgTHPS to prepare the deodorizing passivation double-effect cleaning agent for oil refinery of the present invention.
[0032] Available chlorine in the low alkali value sodium hypochlorite is 12%, alkali concentration is 0.35%, potassium pyrosulfate is 3.5%, and alkaline corrosion inhibitor is 2.2%;
[0033] After roughly calculating the internal surface area of the device to be cleaned, use 25kg / m 2 The amount of cleaning agent of the present invention is diluted with water. The diluted cleaning agent is added to the dosing tank, and the refining unit to be cleaned is connected to a temporary pipeline to form a circulation system. Accor...
