Maintenance of thesystem (operation costs) is reduced byas much as 40% depending on operatingparameters, not including liquid losssavings due to less plumbing and cooldown requirements.

Whattends to result is a substantial amount ofcondensation and added precipitationon vaporizer surfaces that quickly freezeinto dense pockets of ice, reducingvaporizer capacity. Extra surface areamust be added to reduce the effects ofthis atmospheric phenomenon.Likewise, the vaporizers need to beswitched much more often to preventthe formation of very dense ice that willnot defrost during off periods if levelsget too substantial. Often vaporizersmust be sized based on two to three dayratings, but switched every two to sixhours to prevent ice buildup.Micro Climate ZonesMicro climate zones exist in every oneof the zones discussed. They are definedas zones that may result in substantiallydifferent weather conditions and mayexist at distances as close as 31miles(50 km) from one to the other. Microclimate zones may have unique wind orprecipitation design requirements. Anexample is the area downwind of theGreat Lakes region in the United States,where major snow fall accumulationscan occur when dry cold winds moveover warmer moist lake air causing theair to become saturated and creatinglocalized “lake effect” snow. Other commonweather phenomenon such as theChinook winds of Montana, the buranwinds of Russia and Central Asia, thebora winds of the Northern Adriaticcoast of Yugoslavia, and the Santa Anawinds of Southern California may resultin special mechanical design requirementsor height limitations due to thesevere winds caused by the venturieffects of local mountain canyons.Altitude effects need to be considered aswell, with appropriate capacity reductionapplied to the vaporizer models.For more information, contact PatrickBillman at Cryoquip, billp@cryoquip.com.Cosmodyne has commissionedan ASPEN 1000 Series air separationplant in mineral-rich Dares-Salaam,Tanzania.
