CONTROL VALVES KOSO HAMMEL DAHL Cryogenic Service Cold Box and Yard Valves
CONTROL VALVES KOSO HAMMEL DAHL V817 Cryogenic Globe Valve Size 1-6 Class 150, 300, 600 Body Matl: 304 Stainless Steel End Connections: –Raised Face Flanges –Socket Weld –Butt Weld Soft seat option provides class VI tightness
CONTROL VALVES KOSO HAMMEL DAHL V817 Cryogenic Globe Valve Features bolted bonnet joint that is outside of the insulated barrier extended stainless steel body removable trim without accessing the insulated barrier all welded construction within the insulated barrier
CONTROL VALVES KOSO HAMMEL DAHL G120 Cryogenic Globe Valve Features post guided plug extended stainless steel body easily accessed seat ring Typically used for warm service Yard valves Outside of cold box
CONTROL VALVES KOSO HAMMEL DAHL V815 Series Similar to V817 except; –Special face-to-face dimensions Weld-on flanges –Available with bronze body Was used by only Air Products Offer V817 unless APCI or direct replacement
CONTROL VALVES KOSO HAMMEL DAHL Cryogenic Air Separation Air Feed –Air is drawn into the plant by main air compressor. Cleaning – The air goes through a filter house to remove dust and large particles. –The air is then cooled and cleaned of CO2 and moisture by passing it through a molecular sieve drier.
CONTROL VALVES KOSO HAMMEL DAHL Cryogenic Air Separation Compressing –The air is compressed to high (150 psi) pressure for expansion. Cooling –The cool and dry air is then cooled even further to -300°F (-185°C) in the main heat exchangers and is then sent to the distillation column.
CONTROL VALVES KOSO HAMMEL DAHL Cryogenic Air Separation Separation –The air is separated into its elemental components in the form of liquid oxygen, argon and nitrogen, based on its different boiling points. –The more volatile components, nitrogen, will rise up and oxygen will go down while argon will be somewhere in between.
CONTROL VALVES KOSO HAMMEL DAHL Cryogenic Air Separation The pure products are drawn off to: – store in cryogenic storage tank, –deliver to the customers by liquid tanker –or pure products are feed to customer by pipeline network.
CONTROL VALVES KOSO HAMMEL DAHL Mark Six –Integral seat –Threaded available Now used by Air Products Valtek
CONTROL VALVES KOSO HAMMEL DAHL Samson Model 3248 –Standard bellows seal prevents stem leakage Now used by Praxair
