The basic requirements of global storage tank owners for storage tank cleaning are generally as follows:
The following describes the places that need special attention when cleaning large capacity raw oil tanks. It can be said that the more the effect is better;
1. Shorten the cleaning cycle requirements
Large capacity tanks contain large amounts of deposited sludge, and some methods are manual, requiring a cleaning period of 6 months to 1 year. This means that oil tanks cannot be used for long periods of time, and the utilization of storage equipment is very low. Therefore, regardless of the size of the tank and the amount of sediment, the cleaning project should be completed in a short period of time.
2. Requirements for cleaning efficiency
The cleaning method must be reliable and efficient and independent of tank size, amount of sediment and other factors.
3. Security requirements
Master safety at work so that you can avoid the consequences of human negligence and catastrophic factors such as fires and explosions.
4. Requirements for resource reuse
The useful part of the sediment should be recovered and reused as a resource.
(5) The requirement that the recovered crude oil be recovered in good condition without recorruption
6. Requirements to reduce the loss of large amounts of sediment
7. Environmental protection requirements
8. Requirements for labour-saving mechanized methods
Working in oil tanks is one of the dirtiest and most dangerous jobs. The staff obviously do not want to work in such a bad environment for a long time, the fire may occur at any time, in addition to the poor working environment is easy to cause fatigue and low work efficiency;
Working methods that rely solely on human labor should be avoided in favor of methods that minimize the amount of dirty work in the tank, which means promoting mechanization and saving labor;
The mechanical method developed by Beijing Altron Technology Development Co., Ltd. at the beginning of the new millennium to remove the bottom of the storage tank slag and sludge has been welcomed by customers;
9. Requirements that are not affected by tank location
The cleaning work can be completed without steam, electricity, water, sewage tanks and waste liquid treatment equipment.
10. Economic requirements
The cleaning method should be economical in terms of various investments, for example, utility costs (steam, water and electricity), chemicals, sediment treatment, sewage treatment, return oil, recovery oil volume, working life, tank service downtime, machinery, raw materials and manpower.
