沉积在原油贮罐里的淤渣,具有流动性,但时间久了就变硬,在常温下不能流动。据调查在石油、石油化工等部门,此一现象普遍存在,急待清洗, 固化沉积时,可采用如下方法。如图所示,减少贮罐内原油量,用泵使之循环。如可能用加热盘管加热淤渣固化沉积层软化或使之呈流动状态。如没有条件用加热盘管,则可加热循环的原油,间接使淤渣受热,24小时后,乳化淤渣在40℃左右能均匀分散在原油
Sludge deposited in crude oil storage tanks is fluid but hardens over time and can not flow at ambient temperatures. According to the survey in the petroleum, petrochemical and other departments, this phenomenon is widespread, urgent cleaning, curing deposition, you can use the following method. As shown, reduce the amount of crude oil in the tank and circulate it with a pump. If possible, heat the sludge with a heating coil to cure the deposited layer to soften or allow it to flow. If there is no condition with the heating coil, you can heat the circulating crude oil, indirect heating of the sludge, after 24 hours, emulsified sludge around 40 ℃ can be evenly dispersed in the crude oil
