OSD-F CE with ASME certificates of high quality nitrogen dryer used for oil and gas, electron field
Nitrogen dryers mainly used for remove the water of the main raw gas(nitrogen) , adsorption of hydrocarbon, halogenated hydrocarbons, organic sulfurous,nitrogenous and oxygenous compounds.
The dryers working process : Raw gas-water removing & removing other impurties-filtering-outlet .
This equipment including dryers, filters etc, the raw material will enter into dryers for removing water and impurities, two dryers working in turn , fully automatic switching (one working ,one standby), to finalize continuous drying . This process requires high efficient and quality adsorbent, strong, regenerated repeatedly, longer Worklife.After filtering Remove the dust then send the clean/pure hydrogen for working site.
1. Index

2. Control system with its function
Fully automatic regeneration procedures control
PLC via the programming and parameter for operation, import and export signal, to control valves, heating elements start up and shut. To realize two dryers fully automatic switching working and regeneration .
2.1 Temperature control
Temperature controlled by PLC, SCR, thermocouples, heaters etc. All the parts will be via thermocouples inspected and transfer signal to PLC, PLC will according to programming , control SCR electric current thus control each parts. With temperature settings , alarming and blocking
protection to guarantee equipment safety working .
2.2 Alarming & blocking protection
Alarming functions including : temperature alarming, flow alarming, index alarming
