    Electric or Steam driven Air Compressors?

    zdas04 - We are not getting any benefit from using teh same air if you're talking about the air we're moving through the tanks. Let's say it's toxic and we have to contain it throughout the series of tanks until it's all consumed in teh process. That's not exactly accurate, but it's a good...

    Electric or Steam driven Air Compressors?

    zdas04, It's more than just getting compessed air to each of 300 tanks. We have a containment of air that starts at the first tank and is passed through each of the 300 tanks and is vented at the end. That gas has to be maintained separate. How do I get that gas from the top of 1 tank to the...

    Electric or Steam driven Air Compressors?

    David/dcaasto, Thanks for the quick reply. Our design requires 300 tanks of liquid all linked together in a series and we are passing 1200 cfm of gas through the series of tanks. I have to get the gas from teh top of the 1st tank and into the bottom of the next tank and overcome a 40 foot...

    Electric or Steam driven Air Compressors?

    I have a design conditon where I have to decide whether to use electric or steam driven air compressors. The requirement for electric is 300 250HP (200kW) motors that will move 1200 CFM at 90 PSIg. If I run them 24/7/365 at $0.08/kWh (an annual average), the cost is 200*24*365*0.08 = $140k/yr...
