Tank Bottom Sludge Treatment
Methods of HYang Tank Bottom Sludge Treatment:
1. Microbial Engineering Technology.
2. Indirect Thermal Desorption Unit.
3. Chemical Hot Washing Treatment Technology.
Various oil smudges come from different areas, the sludge condition may different from each other. For a suitable solution on recovering the valuable liquid from the sludge, following questions are needed to be clear for HYang to provide the best proposal for your oil sludge treatment solutions.
What is the origin and geographic location of the waste sludge (drilling, refinery, other)?
What is the composition of the oil sludge (percentage of oil, water and solids)?
How is the volume of oil sludge to be treated?
How long you need to complete the treatment of the oil sludge?
What is the challenge or problem of the current situation?
What is the target to be achieved for the final oil, water and solids?
What process / equipment are being used on site at present for the oil sludge treatment?
How is the performance now?
What's your budget for setting up the oil sludge treatment plant?
At present, Huayang has three treatment methods for oil sludge, one is the harmless treatment of microbial engineering technology, the other is the treatment of indirect thermal desorption equipment, and the third is chemical hot washing treatment technology.
1. Microbial Engineering Technology
This technology adopts high-efficiency biological enzymes and modern microbial fermentation engineering technology to carry out engineering, harmless and resource-based treatment of various types of oily sludge. For oily sludge with oil content ≥ 10%, high-efficiency biological enzymes are used to separate the oil, mud and water in the oily sludge to achieve crude oil recovery.
For various types of oily sludge with an oil content of less than 10%, the special microbial complex flora that uses crude oil and various pollutants in the sludge as the only nutrient source to grow and reproduce, through complex biological and chemical processes, the harmful components are efficiently degraded, transformed and utilized to detoxify, degumm, desalinize and dehydrate, and finally achieve the purpose of biological harmless treatment.
2. Indirect Thermal Desorption Unit
The thermal desorption complete set integrates the process into the following modules: feed bin, feed conveyor, thermal desorption furnace, condensation system, oil-water separation system, non-condensable gas treatment system, slag cooling system, discharge conveyor, flue gas treatment system, heat dissipation system, automatic control system, nitrogen generator, and the transfer flow of solid phase, liquid phase and gas phase medium is carried out between each system module through scraper conveyor or pipeline.
Technology Advantages
A.The complete set of equipment is equipped with various detection devices and supporting automatic linkage control programs, and the safety is greatly improved compared with the previous equipment.
B.The power system and heat exchange system of the complete set of equipment have been re-optimized and designed, which is more energy-saving than the previous equipment.
C.The oil-water separation system has been re-optimized and designed, adding a variety of sensors and matching a variety of actuators, which greatly improves the automation of the oil-water separation system compared with the previous equipment, and reduces the degree of manual participation.
3. Chemical Hot Washing Treatment Technology
(1) After treatment, the oil content in the solid phase is stably controlled below 0.45%.
(2) Recovery of oil phase, turning waste into treasure.
The complex heavy oil sludge fine chemical hot washing treatment technology, by integrating a variety of advanced technologies and equipment, enables the pollutants in the waste to be separated and cleaned step by step, the liquid phase is separated from oil and water, and the oil phase is recovered.
(3) Suitable for all kinds of complex sludge treatment.
This technology and supporting equipment are widely used in tank cleaning sludge, floor sludge, scum, mixed oil sludge and other types of sludge treatment.
(4) Low temperature decomposition, natural reduction, green and pollution-free.
This technology is derived from the principle of natural cleaning, mainly using low temperature chemical and physical separation, no secondary pollution in the process, and efficient separation of clean soil and sand while degrading pollutants.
(5) The amount of sludge processed is large, and the equipment runs stably.
The average daily processing volume of complex sludge is stable at about 150 tons.
(6) High safety of equipment operation.
The material heating temperature is controlled at 80-90"C, which has high safety.
(7) Recycling of water resources.
The process water is recycled for secondary cleaning to save water resources.
(8) Skid-mounted design is easy to move and relocate.
The equipment adopts a skid-mounted structure, and the functional components of each process equipment are integrated into an overall base.
Easy to install and relocate, the skid-mounted equipment has a compact structure, a small footprint, moderate degree of automation control, low labor intensity, simple operation, convenient operation and management.
Comparison of Existing 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 | 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℃inanoxygen-free environment, transformed into, and then cooled into 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, the 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. | Strains' performance and technology play a decisive role, high technology content, environmentally friendly, thorough treatment, economical and efficient | Long action time and large area |
