Butane unloading method
Thread Content
I would like to ask what methods companies use for unloading n-butane. We use nitrogen for pressurization, but this approach has two drawbacks: first, it is costly; second, the release of nitrogen leads to a decrease in pressure, which affects the quality of the gas. Are there any good methods? Are there any compressors or vaporizers that are particularly effective?
Starting from the first floor, I earnestly ask all experts for their guidance!
The compressor extracts the gas phase from the tank and returns it to the vehicle to build up pressure, facilitating an increase in volume.
We also installed a compressor, but there is one problem: there isn’t enough gas in the n-butane tank, so the compressor can’t draw in air； If nitrogen pressure is added, the existing units will not be able to compress.
You can’t have just one tank, there will be air leakage! Nitrogen affects the quality of the gas, but why would the cost be high?
Generally, the compressor is used to pump air into the tank where the liquid is to be unloaded; by increasing the pressure, butane in the pipe is forced to flow into the storage tank, which is very convenient
