Installation of the pre-cooling line for liquid ammonia unloading
Thread Content
What is the configuration of the pre-cooling line for liquid ammonia unloading? Is pre-cooling only required during the first unloading?
The liquid ammonia unloading pre-cooling line is typically a pipeline connected to the storage tank, equipped with valves and connectors, used to pre-cool the unloading pipeline with the low-temperature liquid ammonia from the storage tank before starting the unloading process. This prevents the liquid ammonia from vaporizing when it comes into contact with hotter pipes, thereby avoiding pressure increases. Typically, pre-cooling is required before each unloading to ensure safety and reduce liquid ammonia losses. .
Is a pre-cooling line required for unloading liquid ammonia? What is this design? Are all the liquid ammonia pipelines in your company bare pipes? Was the pipeline not designed with insulation? As long as the pipeline has proper insulation, pre-cooling is not required for unloading liquid ammonia; instead, the gas phase from the storage tank is directly pumped into the tank truck, and the pressure difference is used to push the liquid phase from the tank truck into the storage tank. If the material is ethylene, it is necessary to pre-cool the liquid-phase pipeline before unloading.
Dude, if ethylene is used, shouldn’t the same principle apply to liquid ammonia?
Is there anyone who is familiar with suppliers of butylene unloading compressors? Which ones are more reliable
This compressor has low requirements; it can be purchased on Taobao
