Drying and dehydration of compressed natural gas for vehicles-4A molecular sieve
Since raw natural gas contains a little moisture, hydrates will form when the ambient temperature is equal to or lower than 0°C, blocking pipelines. In addition, natural gas contains carbon dioxide, hydrogen sulfide and other gases, which can easily form acid with water, causing damage to equipment and pipelines. corrosion. Hydrates will be generated during decompression and cooling under storage pressure, which will block pipes, gas bottle nozzles, charging nozzles, etc.,
