Hi! I have an air cylinder that is compressed to 150 PSI with a volume of 7.3 cu in. I am trying to find out how long it will take for the 150PSI to vent down to atmospheric pressure through an opening that is 1.77mm in diameter. Greetings

Hi! 1- If you are starting up a cold steam heater and you hear a noise, what would the action to be taken? 2- What is the difference between spectacle blind and sleep plate? Greetings

Hi! We had a compressor with inlet pressure 14 barg to outlet one 45 barg(design) for feeding gas with(3.0 MM Sm3/d) to LPG plant. we were controlling the pressure in the unit by turboexpander control valve (Completly different from conventional pressure control valve).Now,we're planning to...

Hi! Why do they always use propane as coolant in industrial refrigeration loop and not for eg Butane? for eg in our LPG plant. Greetings

Hi! Please is anyone tell me how to compute the total charge of propane used as coolant in refrigeration loop of a LPG plant? Thanks!

Hello everybody! Can everybody tell me what does mean process optimization . Does it mean, the best working parameters with low energy consumption or money saving? or is there something else. And what are the stages taken to make a process optimization Please give me some technical support to...

Hi! I a have hydrocarbon gas mixture whose total pressure is Pt(measured by gage)over 40Barg. Is it correct for computing the partial pressure of components by using this formula: Pi(partial pressure of one component), Yi(molar fraction) Pi= Yi * Pt Thanks

Hi! We have a LPG plant where regeneration(Heating phase) of Molecular sieve bed of dehydration unit is performed by heated gas in mineral oil Shell-tube heat exchanger. However, a new LPG plant where construction is underway and the regeneration of the Molecular sieve bed is performed by the...

Hi! Why do they make a TSHH for centrifugal compressor? Many thanks
