Oily Sludge Treatment
New oily sludge treatment technology through microbial engineering.
Hazard-free, safe, highly-efficient and don't need complicated machinery system.
Treat oily sludge and increase oil production.
Oily sludge mainly refers to solid waste generated in the production process of crude oil extraction, storage, gathering and transportation, processing, etc., including floor oil sludge, clear tank oil sludge, scum bottom sludge, dewatered drilling mud, crude oil storage tank cleaning sludge, refinery plant waste oil sludge and drilling waste oil sludge, HYANG provide oily sludge treatment through microbial engineering technology.
Comparison of Main Oily Sludge Treatment Methods
Treatment method | Technical principle | Advantage | Disadvantage |
Dehydration/Landfill | Mechanical separation to reduce moisture content, drying and weathering, digging pits for landfill | Simple process | Poor effect, pollutants are not removed, long-term pollution |
Solvent Extraction | Extract petroleum hydrocarbons (PHC) with organic solvents to achieve oil and mud separation | Strong universality, solvent recycling | The solvent is volatile, toxic, complicated in process, and difficult to treat mud and water |
Incinerate | High-temperature combustion | Mature technology and thorough handling | Cause secondary pollution, high cost and high energy consumption |
High-temperature pyrolysis | Indirectly heated to 400℃500℃in oxygen-free environment, transformed into a gaseous state, and then cooled into the oil phase | High recovery rate of dirty oil | High equipment and operating costs, high energy consumption, difficult mud and water treatment |
Thermochemical washing oil+centrifugal dehydration | After heating and adding chemical solution, PHC is washed out and the oil, water and mud are separated through flocculation, sedimentation and centrifugation. | Strong adaptability, high recovery rate, mature technology | High cost, complicated process, causing secondary pollution |
Microbial Treatment | Microbes decompose, transform and use PHC and other pollutants in the process of growth and reproduction to achieve harmless treatment. | Strain performance and technology play a decisive role, high technology content, environmentally friendly, thorough treatment, economical and efficient | Long action time and large area |
Oily Sludge Treatment by Microbial Engineering Technology
HYANG microbial engineering technology for oily sludge treatment uses high-efficiency biological enzymes and modern microbial fermentation engineering technology to carry out engineering, harmless, and resource treatment of various oily sludge.
Oil content ≥10%
Firstly uses high-efficiency biological enzymes to separate oil, sludge, and water in oily sludge to realize crude oil recovery.
Oil content＜10%
Use crude oil and various pollutants in oily sludge as the only nutrient source to grow and multiply special microbial compound flora, through complex biological and chemical processes, oily sludge harmful components for the ecological environment are efficiently degraded, transformed and utilized to make them detoxify, degummed, desalinize, dehydrate and finally achieve the goal of biological harmless treatment for oily sludge.
How does HYANG strain microbe?
Our technician isolated a number of strains from petroleum-contaminated soils in three major oilfields, strains with high production surfactants and petroleum hydrocarbon decomposing bacteria with a high degradation rate of contaminated crude oil, and carried out modern microbial breeding. We obtained engineered strains that can be used in the production of biosurfactants for industrial production and harmless oily sludge treatment. These microbes can live on oil themselves, don't need additional broth of nutrients.
