I am trying to figure how can I calculate the ideal Tryethylene glycol injecttion rate to prevent hydrate formation on a subsea pipeline gas flow rate about 300 MMSCFD

Replying to MacGyverS2000 , excellent approach except whoever is going to get a bucket of gas ( In gas state) will probably get a Nobel price in Material Science.

How do I measure that then?

Replying to waross. YEs it is a closed valve

I am trying to calculate how much flow is going through a valve that i am suspecting is passing. What formula can i use, please i need this urgent help. Thank you

I have an assignment that I quiet struglling with. We have a propane Tank that after inventory will hold around 6K lbs of propane. I have to come up with plans to remove that propane in order to let maintenance perform work inside the tank. What can I use to remove , by flaring this remaining...

I have this doubt, They are going to recertify couple of PSV's in the Unit, but I was wondering if one assesment I should consider is opening the bypass around a thermal relief Pressure Safety valve, if pressure increases close to PSV set point. What about fire PSV?

Replying to :1503-44 (Petroleum). Thanks alot for your time and your help. I appreciate from the bottom of my heart. Have a blessed day and stay safe.

Replying to 1503-44 (Petroleum). Yes correct, the reference pressure is 14.696 psia and 68 F.

Replying to 1503-44 (Petroleum). That means for that gas composition 1 MMCFD will give an equivalent density of 3.55 lbs/ft3? . How do i relate that to the mass flow in lb/hr?

is about 80.44 C1, 8.71 CO2, 4.92 C2, 3.43 I-But, 0.55 I-But, 0.92 N-But, 0.28 I-Pent, 0.19 N- Pent, 0.18 N2, 0.38 C6+; they all about 1000 PSI and 80 F.

My only little concern is to figure if Standard Cubic Feet and Cubic feet will give me an approximation. I understand standard takes into account standard conditions.

Hello, I am struggling big time converting MMSCFD of natural gas to lb/hr. I would greatly appreciate any help.

I need guidance on ho to find the following: Maximum Allowable Working Pressure Maximum Allowable Operating Pressure Maximum Operating Pressure Relief Pressure

Fellows, I am trying to calculate the cost of a PFR reactor. Anyone here has a good document step by step that I can use for this purpose. I have been looking online and could not find anything.

@GEOGERVERGHESE, What is N, Do, L. How do i find out the Do(assuming thats the outside diameter????

I am actually designing the evaporizer of a Process Plant that produces acetone.

[b]Dear friends, I am trying to calculate the Internal area of a tube in an evaporizer. I am using the formula (pi*D^2)/4, How to I determine the D? I understand that's the diameter of the tube. Please help .

What do you mean by diluent flow?

I have calculated to have about 7k lbmol per hour of Isopropyl Alcohol, I would like to convert that into concentration to calculate the rates. using -ra=k(Cao(1-x)/(1+xa). How do I convert this flow lbmol/hr into concentration units. Please help
