Industrial, elemental and calorific value analysis methods for oil sludge

(1) Industrial analysis of oil sludge The industrial analysis method of oil sludge adopts the industrial analysis method of GB/T 212-2008 coal. Since the water content has been obtained by distillation, the ash content, volatile matter content and fixed carbon content of the sample are determined only by this method. Ash calculation formula for oil […]

Cement kiln co-processing hazardous waste in the engineering design needs attention

As a new type of hazardous waste disposal technology, cement kiln co-disposal of hazardous waste has many advantages such as high disposal rate, high disposal volume, environmental protection emission standards, various types of disposal, low project investment, short construction period and low disposal cost. Gradually gain wide recognition. In recent years, especially in 2017 and […]

Analysis physical and chemical properties of oil sludge

Oil sludge has been included in the HW08 waste mineral oil in the Hazardous Waste List. The composition of oil sludge is very complex, and it contains a large amount of aged crude oil, solid suspended solids, salts, bacteria, corrosion products and the like. The slag-containing rate and oil-bearing rate of oil sludges from different […]

Introduction of oil sludge treatment technology

Oil sludge can be classified into two categories according to the treatment technology characteristics: The first type is oil sludge treatment technology based on harmless treatment, including oil sludge filling method, oil sludge solidification method, and oil sludge. Biological treatment method, oil sludge control and re-injection method; the second category is oil-based sludge treatment technology […]

Brief introduction of oil sludge treatment technology

People’s awareness of environmental protection and strict environmental standards have made it necessary to detoxify, reduce, and recycle oil sludge containing petroleum resources. At present, the oil sludge treatment technologies mainly include: oil sludge solvent extraction technology, oil sludge incineration treatment technology, oil sludge chemical hot washing technology, oil sludge thermal treatment technology, etc., in […]

Principle of pyrolysis of oil sludge

Pyrolysis of oil sludge is also called thermal cracking of oil sludge. It is to decompose organic matter in an oxygen-free state to: 1 solid residue mainly composed of coke and carbon black; 2 in liquid form at normal temperature of fuel oil; 3 chemical decomposition process of flammable gas mainly composed of H2, CO, […]

Factors affecting pyrolysis of oil sludge

The change in pyrolysis parameters has a significant effect on the pyrolysis reaction of oil sludge. According to the research and analysis, the parameters that have a great influence on the pyrolysis process of oil sludge are pyrolysis temperature and pyrolysis time, while other parameters such as heating rate, residence time of pyrolysis gas, type […]

Summary of sludge treatment methods

Various sludges have their own characteristics, and many technologies are applicable to these sludges. The technologies used are different depending on the treatment requirements. The sludge treatment generally includes landfill, fertilizer, power generation, heating, etc. method. So let’s talk about the specifics of the sludge treatment methods, and what are the different treatment methods. Sanitary […]
