Abstract

The invention discloses a demulsifier for decomposing petroleum-based oil slurry. The demulsifier for decomposing every 100 parts of petroleum-based oil slurry is prepared from the following raw materials in parts by weight: 0.4-0.9 part of sodium carbonate, 3-5 parts of industrial salt, 3-4 parts of sodium silicate and 0.4-0.9 part of sodium sulfonate. The using method of the demulsifier comprises the following steps: measuring the content of oil in the petroleum-based oil slurry in storage equipment, and determining the amount of each component to be added into the demulsifier according to the oil content; heating the petroleum-based oil slurry to 60-70 DEG C by heating equipment, sequentially adding sodium carbonate and stirring for 30 minutes, adding the industrial salt and stirring for 30 minutes, adding sodium silicate and stirring for 120 minutes, and adding sodium sulfonate and stirring for 60 minutes; standing and extracting supernatant oil; discharging ash component and water into a reservoir, standing and precipitating; and solidifying and embedding sands at the lowest layer. According to the method, sodium carbonate, industrial salt, sodium silicate and sodium sulfonate are synergized and matched, the proportion difference can be increased, the molecular chain can be opened, and water, ash component and sands can be easily separated from oil.

Description

technical field [0001] The invention belongs to the technical field of petroleum-based oil sludge treatment, and in particular relates to a demulsifier for decomposing petroleum-based oil sludge and a use method thereof. Background technique [0002] When crude oil contains water and sediment, it is usually decomposed by traditional demulsifiers by heating, but some crude oils are difficult to separate with traditional demulsifiers due to the long time and the complexity of impurity content. The composition of sewage sludge in refineries is more complex, including water, sediment, activated clay, ash and chemical components other than oil. Various substances are tightly contained together, and it is difficult to decompose them. In recent years, people use the method of centrifugal force to separate water, mud and oil. Since the proportion of petroleum ash is equivalent to that of petroleum, oil and ash cannot be separated together, and ash is linked with chemical components ...
