We are planning to feed 30% HCL acid from totes using gravity. The required flow rate is 10 L/min. Could anyone suggest me the equations used to calculate the height required to achieve this flowrate and the pipe size.

Could anyone suggest me the standards for HCl piping and pumping. We are planning to pump 30% HCL from totes to our fumehoods using metering pump and gooseneck. any suggestions are welcome...

We are trying to install a HCL dosing system from HCL totes to our fumehoods. Can anyone suggest a good dosing system for such application.

Hi all, I need to calculate the outlet composition of gas coming out of a sealed HCL tank having an air inlet and an outlet. The temperature inside the tank is 20oC and pressure is at 1 atm. The tank is half filled with liquid HCL. I know the flowrate of incoming air. Any hints regarding this...

is there any way to calculate the amount of water in bio-gas having 90% relative humidity at 37 deg C and pressure above atomspheric??

Could anyone suggest the best polymer to be used for dewatering hog manure sludge @ 15% solids. The sludge is coming out of a secondary digester. What type of polymer (dry, emulsion) proves best for dewatering??

hi, I am in a process of justifying purging operation for one of our anaerobic digester. What are the chances of methane to react with oxygen to produce co2 and water?? one of my collegue thinks that methane being produced will react with oxygen to product carbon dioxide and water, so the...

hi, I am trying to get some info on AD accidents - most references I see talkabout the possibility of explosion, but I haven't heard of specific instances and I'm trying to get a handle on whether they are rare, extremely rare, never happen or happen more often than you'd think but aren't...

We have anaerobic digesters which require frequent maintenence activities. Has anyone heard of purging the digester tanks?? Our concern is to reduce the oxygen content in the digester below the explosive limit. One of our senior engineer has the view that in a digester system the explosive range...

We are currently involved in a feasibility study for a hog manure treatment plant utilizing primary and secondary anaerobic digesters along with a dewatering option. The sludge from secondary digester is 82,000 kg/day @ 15% solids. we are planning to use a cationic polymer, 10lb/ ton DS for...
