Crude oil storage tanks use internal or external floating roofs
Thread Content
For a 10,000 cubic meter crude oil storage tank, is an internal floating roof or an external floating roof better? We think an internal floating roof is more cost-effective, but the owner says an external floating roof is cheaper
Please confirm whether it’s 10,000 or 100,000. Is a crude oil tank of 10,000 units too small for now?； Crude oil tanks are equipped with wax-scraping facilities. If the internal floating roof is made of aluminum, can’t the wax-scraping mechanism be installed? If it is made of carbon steel, then indeed there is an additional roof plate compared to an external floating roof.
1 million tons per year of crude oil, using 3 storage tanks of 10,000 cubic meters each
The medium is not sensitive to environmental pollution around it, so there is no need to add an additional top to the internal floating roof. An external floating roof will do ； Why make three such small jars? Shouldn’t the construction and operation costs be lower for something that is a bit larger?
Under no circumstances should two storage tanks be designed and installed, as it is inconvenient to clean and maintain them. This is exactly the situation we’re facing: there are 2 storage tanks, one of which needs to undergo an inspection upon expiration, while the other tank operates independently and cannot ensure a situation where one tank takes in material while another discharges it.
