Oil storage tank environmental protection problem
Date：2019-09-08 / Popularity：
The tank cleaning machine project is a scientific system engineering for cleaning tanks. With the large-scale construction of large-scale oil storage tanks in China and the increasing emphasis on environmental protection issues, manual tank cleaning has not met the objective requirements of environment and development, and the elimination of manual tank cleaning is a historical necessity. After the oil storage tank is used for a period of time, impurities in the crude oil will deposit on the bottom of the tank and the tank wall, which will reduce the effective capacity of the oil storage tank and affect the efficiency of the oil storage tank.
Therefore, the oil storage tank needs regular inspection and maintenance and removal of the tank. Internal sludge, the traditional domestic tank cleaning method mainly uses artificial, manual clearing tank has the problems of high labor intensity, long construction period, poor safety, low crude oil recovery rate and environmental pollution. With the large-scale construction of large-scale oil storage tanks in China and the increasing emphasis on environmental protection issues, manual tank cleaning has not met the objective requirements of environment and development, and the elimination of manual tank cleaning is a historical necessity. Crude Oil Tank Cleaning System (COW) The International Crude Oil Tank Cleaning System (COW) was developed 20 years ago. This technology is an onshore tank cleaning machine system developed internationally and has obtained relevant patents. It is widely used in tank cleaning machines in Southeast Asia, Europe, the Far East and Southeast Asia.
To date, more than 800 oil storage tanks have been successfully cleaned using this process technology.After nearly two decades of development and improvement, COW crude oil cleaning system is the world's leading level in the application of oil storage tank cleaning on land. The main advantages of the COW crude oil storage tank mechanical cleaning system 1. The crude oil recovery rate is high. The COW method can recover the oil in the sediment to the maximum extent, and the recovery rate accounts for more than 98% of the total sediment. Only 2% of the oil and rust and mud sand are basically free of oil, and the artificial tank is to put all the sediments. When the residue is manually cleaned, it causes pollution and waste. Taking a 100,000 cubic meter oil tank of Qinhuangdao Oil Transportation Company as an example, if the traditional artificial tankcleaning needs about 1600 tons of sediment to be treated, and mechanicalcleaning with COW equipment, it is necessary to manually handle the residue of spray dead angle (rust, sand). , sundries, etc.) only about 1 ton.
