Description

An integrated oil sludge component measuring device

technical field

The utility model relates to an oil sludge component measuring device.

Background technique

A large amount of waste oil sludge will be produced in the process of oil extraction, storage, production and processing. It is reported that every 500 tons of crude oil produces 1 ton of oil sludge, and my country's petroleum industry produces about 3 million tons of various oil sludge every year. Oil sludge is a mixture containing petroleum hydrocarbons, water, inorganic solids, etc. It is a high-risk pollutant. my country has included oil sludge in the "National Hazardous Waste Catalog", my country's "Solid Waste Environmental Pollution Prevention Law" and "National The Cleaner Production Promotion Law requires that oil sludge must be treated in a harmless manner; at the same time, because oil sludge contains certain petroleum hydrocarbons, oil sludge is also a precious energy resource. Therefore, the research on oil sludge recycling and harmless treatment technology is a hot spot that everyone pays attention to in recent years. The analysis of oil sludge composition is one of the technical foundations for the research on oil sludge recycling and harmless treatment technology.

Water content, oil content, and solid (mud) content are commonly used to indicate the composition of sludge. At present, the analysis methods of sludge composition mainly include solvent extraction-gravimetric method, high temperature gravimetric method, solvent extraction spectrophotometric method, etc.

Shen Mingle et al. used solvent extraction-gravimetric method to analyze the composition of the landed oil sludge, that is, after using dichloromethane solvent to extract the oil in the mud sand, then volatilize and remove the solvent to weigh the oil content, and then dry and weigh the extracted residual mud sand to obtain the mud content or solid content. The difference is the water content. Li Zengqiang and others used the solvent extraction-gravimetric method to analyze the components of the sludge at the bottom of the tank, that is, dry the sludge with a constant weight at 105°C to 110°C, measure the water content of the sludge after the weight loss, and use a solvent (such as petroleum ether) to extract the sludge and remove it by volatilization. After the solvent is weighed, the oil content is obtained, and the rest is the mud content. The solvent extraction-gravimetric method requires a lot of equipment, such as an extraction device, a solvent volatilization recovery device, and a constant weight device; After the solvent extraction process, the oil and the solvent are separated by a solvent recovery device, and a small amount of solvent contained in the oil is volatilized and removed; Components) cannot be separated or lost from the solvent, so that the oil content value is low.

Xie Zhihai et al. used the high temperature gravimetric method to analyze the composition of the landed oil sludge, that is, the oil sludge was calcined at 500°C to a constant weight, and the solid content was measured. The water content was analyzed by the carrier reflux method, and the oil content was the amount of the sample minus the water and mud. Li Zhen dried the oil sludge with constant weight at 105°C-110°C, measured the water content of the oil sludge after weight loss, and measured the sludge content by calcining at 600°C with constant weight method, and the difference was the organic matter or oil content. This method also requires a lot of equipment (such as drying constant weight equipment, or reflux equipment to analyze water content, high-temperature calcination equipment, etc.), long analysis time, cumbersome experiments, and oil content when there are easily decomposed inorganic substances in the mud. Or the error of solid (mud) content is relatively large.

Li Meirong used solvent extraction spectrophotometry to measure the composition of the sludge at the bottom of the tank, that is, after the sludge was extracted with petroleum ether, the oil content in the solvent was analyzed with a spectrophotometer to obtain the oil content of the sludge. The water content and mud content in oil sludge need to be measured by other analytical means (such as dry gravimetric analysis of water content). This method requires many types of analytical equipment, a long process, and cumbersome experiments, and the accuracy of the analysis results also depends on the source of the standard sample.
