Hi, Using Peng Robinson EOS for CO2 @ 14 bara and -31C, I got Ro gas = 36.35 kg/m3 and RO liquid (saturation) =1113.16kg/m3; Z gas = 0.8420. Waiting for more detail about your tank(s) and volume gas / Volume total at initial condition. Same for your calculation. Pierre

Data to support your calculations. I've used hot water bath to vaporize CO2. You did not supply enough information to validate your calculation, at least you should share with us your work! Cheers, Pierre

The relieving temperature for a pressure safety valve (PSV) is the temperature of the fluid at the time the valve is expected to open due to an overpressure event. Pierre

for your consideration. Pierre

An interesting paper about gravity flow system in rural areas. Pierre

Hi, Consider this document from manufacturer (Leser) about sound attenuation. Pierre

Hi, Let you consider this resource. can you share an isometric/ PId of your system? Pierre

Hi, Share with us pumps curves and data sheets. I believe this thread is going nowhere. Why these questions? Pierre

Hi, To add to the reply above, you could find on Youtube a set of great lectures on fluid mechanics by Prof Biddle from Caltex : Enjoy the movies. Pierre

Hi, You may want to consider a water tower, similar to what I'm using in my orchard . From the well I transfer the water to the tank (water tower) , the well pump is started by LSL and stopped by LSH . From the water tank I distribute the water to the garden and to the house through a network...

HI, Should be : Zone 2 is a place in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only. These areas only become hazardous in case of an accident or some unusual operating condition. For reference...

Thanks to share with us the composition of the exhaust gas during Normal operation and spikes. Could it be a defect of one piece of equipment (main equipment or analyzer)? Could it be a change of process parameters which affects the combustion? Could it be a stream added for 3 or 4 minutes...

How come? A plant can be shut down, this is a management issue! What is the fluid? what are the operating conditions? Can you take a picture? What is your role within your organization? Pierre

Make sure the sensors are calibrated properly, at the right thresholds. What are the actions in case of concentration high? Hope you did a safety review. Definitely a dangerous area. Operators should have a portable sensor all the time with them. Based on my experience 10 years in soda ash...

Hi, You must have continuous monitoring of H2S! Please review your MSDS or toxicity sheet for this material. Should be an open space. It's heavier than air. Pierre

Check whether you can rent a lorry equipped with a SS tank (25 m3 or above) to store DM water. my 2 cents Pierre

cartridges filters are consumable, don't expect them to last. The only way to monitor their performance is to measure the water drained over the time .Together with the Delta P this is going to tell you when to change the cartridges. Yes, Low Capex but Heavy Opex. You should have performed pilot...

For agitated vessels, doc attached: Pierre Consider these links for ammonia heat transfer coefficient, you may find pointers: https://www.mdpi.com/1996-1073/15/4/1503 https://www.sciencedirect.com/science/article/pii/S1359431124006549

Hi, Consider this resource online: https://checalc.com/fluid_flow_compressible.html I don't have access to Aspen. note: you can build your own excel sheet (paper attached) Pierre
