Decomposition agent for extracting fuel oil from dirty oil mud

Abstract

This invention involves a chemical agent, particularly a decomposition agent extracting fuel oil from sewage oil sludge. The decomposition agent includes (weight percentage): silica 65-75, alum 14-20, sodium hydroxide 4-8, potassium permanganate 0.05-0.1, water 3.9-5, and sodium carbonate 3-4. The decomposition has simple components, and is scientific, rational and effective. Against most sewage oil sludge having acidic characteristics, the basic ingredients such as sodium hydroxide are added to sewage oil sludge for demulsification so as to be close to a neutral pH value, and different components respectively with effects like water absorption, impurities removal, adsorption and coagulation aid are added, which make oil, soil and water degrade effectively, therefore the sewage sludge decomposition and purification effect is effectively improved and sewage sludge degrades more thoroughly.

Description

Technical field [0001] The invention relates to a chemical decomposing agent, particularly a decomposing agent for extracting fuel oil from sludge. Background technique [0002] In the process of oil extraction, a large amount of sludge is often produced. In order to reduce environmental pollution, each oil production well area generally only recovers and reuses part of the sludge that can flow on the ground surface, but is unable to recover the sludge that has penetrated and mixed into the sediment. This kind of sludge generally contains about 35% of crude oil, 40% of water and 25% of silt. Every year hundreds of thousands of tons of sludge are thrown away in vain, which not only causes serious pollution to the environment, but also to oil A huge waste of resources. For this reason, the Chinese invention patent specification with the publication number CN1266245C discloses a sludge decomposer. The decomposition agent is prepared by mixing sodium silicate, potassium permanganate,...

AI Technical Summary

Problems solved by technology

However, in the production practice, it is found that most of the sludge is acidic, and the alkalinity of this decomposer is insufficient, which often leads to the problem of incomplete decomposition of sludge, and the decomposition and purification effect of sludge is not very ideal.
