Seeking help with liquid carbon dioxide storage tank system
Thread Content
The project requires liquid carbon dioxide; a 20-cubic-meter storage tank is planned to be installed, from which the gas will be pumped to the users. I haven’t been exposed to cryogenic engineering before, so I would like to ask: 1. How is commercial-grade liquid carbon dioxide usually transported from outside? Tank truck or cylinder? How do I unload the tank truck (or cylinder) into my storage tank? 2. Parameters of commercial-grade liquid carbon dioxide (temperature, pressure). 3. Although the storage tank has a double-layer insulation layer, it still absorbs heat; what if the temperature rises to a certain level and the carbon dioxide vaporizes? 4. The user requires a liquid carbon dioxide pressure of up to 40 MPa; what type of pump would be suitable? What material is good for conveying pipelines? How do you keep things cold? Thank you
I just searched online for ready-made liquid carbon dioxide storage tanks with a capacity of 20 cubic meters and a pressure of 2.2 MPa; shouldn’t the temperature inside such tanks be below -20 degrees Celsius? Should additional cooling equipment be installed? :o:o
It is recommended that your supplier will answer all of your questions (except the fourth one regarding pressure). 1. How is commercial-grade liquid carbon dioxide from outside generally transported? Tank truck or cylinder? How do I unload the tank truck (or cylinder) into my storage tank? For cryogenic liquids, transport tankers, bottled forms, and pipeline tankers are available, with specialized transportation companies handling these. 2. Parameters of commercial-grade liquid carbon dioxide (temperature, pressure)? Find a market according to your needs. 3. Although the storage tank has a double-layer insulation layer, it still absorbs heat. What if the temperature rises to a certain level and the material vaporizes? There’s no need to worry about this; there is some loss, but it’s negligible. 4. The user requires a liquid carbon dioxide pressure of up to 40 MPa; what type of pump would be suitable? What material is good for conveying pipelines? How do you keep things cold? This pump is crucial; it can be found online, and as long as it can be manufactured, he will provide you with a guarantee. Then there is the issue of pressurization using cryogenic liquid pumps, which requires the procurement of appropriate heat exchangers (vaporizers) as well as suitable fittings and pipes. This is a super-high-pressure gasification system equipment, so it’s best to find a qualified design institute. It would be best if the manufacturer of cryogenic liquid pumps were responsible for the entire process, including design, procurement, and installation. As long as there are enterprises capable of producing such high-pressure, low-temperature pumps, he will provide the other components needed for them. (Enter the keyword “40mpa cryogenic liquid pump” to find manufacturers.) It seems there is one in Wuxi. ）
