    High Pressure Tanks

    I am trying to find a manufacturer of large high pressure tanks (they need to withstand pressures of up to 5000psi). The tank would probably need to be about 600ft3 (or about 4500 gallons). I've never had to purchase anything like this before, and i was curious if anyone had any...

    Phosphoric Acid

    I need to set up an experiment that will use 1-5% Phosphoric Acid Solution at a temp of 180F and pressure of 2000-4000 psig. Does anyone know the H3PO4 will gas-off at these conditions or will it be negligible? (i need to figure out if i need to modify our current vent down conditions or if...

    Use of 5% Phosphoric Acid and Stainless Steel

    I know that phosphoric acid can be dangerous when it comes in contact with stainless steel if its at a high concentration, but from what I've researched, a concentration of 1-5% should not be a problem. However, I need to run the system at a temperature of 180F and from 2000-4000 psig. Does...

    Compression Stages

    Thank you all for your help. We are in the midst of contacting a few different vendors and gettign their opinions and the links that you all sent were really helpful. I have shown all your suggestions to my boss and we are figuring out our best options. Thanks!

    Compressor Staging Calculations

    I have to design a system that will take CO2 at 100 psig and 0 F, and run it through a series of compressors and raise the conditions to 4000psig and 140 F. Knowing this, I need to determine how many compressors are required to increase the pressure (without raising the temp. so high that the...

    Compression Stages

    I have two systems that need to recover SuperCritical CO2. The CO2 leaves the system at approximately 100 psig and 0 F. I need to run it through a series of compressors that will increase the pressure to 4000 psig and 140 F. The second system leaves at a pressure of 950 psig and the temp is...

    Gas Booster Pressure Control

    Hi everyone- I have a question about pressure control. I have to design a system that will use a gas booster (with two pistons) to control the pressure. I've only used gas boosters in one other design, and it was with a constant supply pressure. However, this design is going to be working...

    Water Treatment for Copper Pipes

    We have a water bath with copper tubing submerged in it. The water needs to be treated so that algae and other things do not grow in it, however, the chemicals used can't corrode the copper tubing. Can anyone suggest any products for this problem? Thanks for your help.
