Renewable swill-cooked dirty fuel oil

Abstract

The present invention relates to the field of petrochemical technology, and particularly relates to the field of comprehensive utilization of swill-cooked dirty oil, specifically relates to a renewable swill-cooked dirty fuel oil compounded from the swill-cooked dirty oil and coal tar. The preparation method includes the flowing steps that: less than 40% of simply filtrated and dehydrated swill-cooked dirty oil in any proportion is mixed with the coal tar; and a compatibility agent, an anti-smoke agent and an anti-coking agent which account for 1% of the total mass are added into the mixture to prepare the renewable swill-cooked dirty fuel oil. Problems of high flash point, weak flammability, high-temperature solidification point, difficult transport caused by high viscosity and poor performance in atomization combustion are solved. The fuel oil compounded by the two oils in the invention is advantage in low content of sulfur, high heat productivity, strong flammability, no black smoke, simple production process, low production cost, very high cost performance compared with light diesel oil refined from petroleum, very strong competitiveness in the fields of electric power, building materials and the like. The fuel oil is best alternative oil for fuel oil used in ignition in power plants, cement plants, glass factories and the like, being capable of saving cost of fuel oil and decreasing a large amount of consumptions of light diesel oil and heavy oil for the society.

AI Technical Summary

Benefits of technology

This invention relates to an improved method for producing clean burning oils without requiring complicated steps or expensive equipment like processing them down by removing impurities such as water beforehand. By mixing this raw material with coal-tar pitch instead of crude oil, there are fewer harmful substances present than traditional methods while still maintaining their quality. Additionally, after adding these materials together, they have better properties compared to regular types of lighter fuels used on vehicles.

Problems solved by technology

This patented technology solves the issue where excessively produced waste greases are discarded without being reused because their properties make them difficult to treat correctly. Current methods involve burning away this residue before returning it downstream through public water supply systems. Additionally, there may exist concerns over environmental sanitation issues such as contamination of ground waters during drilling operations. Therefore, an effective new approach needs to address both aspects simultaneously while minimizing costs associated with purifying waste oil.
