Embodiment 1
[0018] The present invention provides such figure 1 A kind of petroleum peptization process shown, concrete steps are:
[0019] Step 1: Put the oil that needs to be gelled into the mixer, and add a debonding agent to the mixer, the mixer works to mix the oil and the degumming agent, and then pass the mixed oil to the oil-water separator, and the oil-water A flocculant is added to the separator to separate oil from water and oil sludge, and the separated oil is collected. The degumming agent is a mixed liquid of oxidant, catalyst and penetrant, the oxidant is sodium persulfate, and the catalyst is ferric nitrate , the penetrating agent is a surfactant, and the use ratio of the oxidizing agent, catalyst and penetrating agent is: oxidizing agent: catalyst: penetrating agent=3:2:1;
[0020] Step 2: Collect the water and sludge processed by the oil-water separator and pass it into another mixer, add citric acid to the mixer, and then the mixer starts to work to mix the water and s...

[0030] The present invention provides such figure 1 A kind of petroleum peptization process shown, concrete steps are:
[0031] Step 1: Put the oil that needs to be gelled into the mixer, and add a debonding agent to the mixer, the mixer works to mix the oil and the degumming agent, and then pass the mixed oil to the oil-water separator, and the oil-water A flocculant is added to the separator to separate oil from water and oil sludge, and the separated oil is collected. The degumming agent is a mixed liquid of oxidant, catalyst and penetrant, the oxidant is sodium persulfate, and the catalyst is ferric nitrate , the penetrating agent is a surfactant, and the use ratio of the oxidizing agent, catalyst and penetrating agent is: oxidizing agent: catalyst: penetrating agent=5: 4: 2;
[0032] Step 2: Collect the water and sludge processed by the oil-water separator and pass it into another mixer, add citric acid to the mixer, and then the mixer starts to work to mix the water and...
