- Advantages
- Solvent-based metal cleaner used as an additive to kerosene, diesel fuel or heating oil.
- Additive consisting of aliphatic hydrocarbons, surfactants and organic corrosion inhibitors.
- For cost reasons, 10-20% of the product in kerosene is recommended. Temperature varies in the range of 20-60°C.
- Quality of cleaning increases with increasing temperature.
- Exact quantity used depends strongly on the type and viscosity of the oil residues to be dissolved.
- Product Overview
Chemical Tank Cleaning and Recycling of Oil Residues
- An unsolved problem of crude oil industry is the environmentally acceptable removal of oil residues in tanks and pipelines. In the course of time highly viscous oil accumulate at the ground of the storage tanks. The capacity of these tanks is several thousand cubic meters.
- To this day the most usual cleaning method for this storage tanks is the mechanical treatment to remove the oil emulsive and solid sediments. This method is costly in terms of time, produces emissions and causes high costs for the disposal of the residues.
- A solution for this problem was created by Keller & Bohacek GmbH & Co. KG in collaboration with professional partners.
- The chemical tank cleaning and recycling of oil residues reduce the cleaning time in comparison with the mechanical cleaning. The grave advantage of the chemical cleaning is the recycling of approx. 90% of the oil emulsive sludge. This will protect the environment, because up to 90% of the sludge can be reused in the refinery and expensive actions of disposal are not necessary anymore.
- Advantage of Chemical Tank Cleaning and Recycling of Oil Residues
- Reuse of 90% of the oil residues
- Reduction of the amount of waste deposits up to 90%
- Time required to clean the tank chemically is only half of the time for mechanical cleaning

- Applications
- KEBOCLEAN KB is a metal cleaning agent containing solvents which can be used as additive for kerosene, diesel fuel resp. fuel oil, to remove oil residues in tanks and pipelines.
- It consists of aliphatic hydrocarbons, surfactants and organic corrosion inhibitors.
- KEBOCLEAN KB even dissolves viscous crude oil residues resp. makes them pumpable so that such substances can be reused in the refinery and expensive actions of disposal are not necessary anymore.
- Dosing
- KEBOCLEAN KB can be used in undiluted form to dissolve persistent scales in the crude oil industry. For cost reasons, however, we recommend the application of 10 – 20% KEBOCLEAN KB in the kerosene at continuous recirculation of this cleaning mixture. The temperature may vary from 20 – 60°C. The performance of the cleaning process will be improved at increasing temperature.
- The exact dosing rate highly depends on the kind and viscosity of the oil residues. A very rough guide would be 500L cleaning solution for 1 m³ oil residues, i.e. 50 – 100L KEBOCLEAN KB per m³ oil sludge to be dissolved.
- Examples / Best Practice
For removal of persistent asphaltenes in crude oil tanks and connected pipelines.
- Description of Cleaning Process
The cleaning process depends on the kind and viscosity of the oil residues. Below the cleaning process will be described exemplary with integrated reuse of oil residues and cleaning liquid.
- KEBOCLEAN KB will be mixed with the calculated amount of kerosene and pumped to the storage tank. The cleaning liquid can take effect at the surface of the oil residues only.
- Therefore the cleaning liquid will be pumped out of the tank and returned to it with the effect, that fresh cleaning liquid has contact to the surface of the oil residues. Kerosene, KEBOCLEAN KB and oil residues in solution are pumpable. When all oil residues are in solution the cleaning process is finalized.
- Agitators, assembled on the roof of the tank, can support the process of dissolving.
- When all oil residues are of liquid consistence, the mixture can be pumped to the refinery to be redistilled to new products. Only the indissoluble fraction remains in the tank and has to be disposed or incinerated.
- The indissoluble fraction must be mechanical removed from the tank and disposed. The minerally amount of oil residues is depending to the quality of oil 4 to 10%. Now the inside walls of the tank can be cleaned by a high-pressure cleaner and after that the tank is ready for inspection.
