I am searching for a database of flue gas scrubber design parameters. Such as, common reagents to use for certain VOC compounds, L/G minimums, and Absorption Factors. I do not have access to programs that can model this data for me. If anyone knows of such a database and is willing to share it...
I have found resources that explain the impact of a 95 deg elbow at the inlet and outlet of a centrifugal fan, but nothing else. I know a sloped inlet and/or a sloped outlet duct would cause a non-uniform velocity profile, which would cause performance losses. But I am hoping there is a way to...
I am a chemical engineer working on a spreadsheet that calculates heat capacity using the Joback method (see links below if you need more information on the Joback method). For this calculator, I am creating a database of chemical compounds and their functional groups, but it is taking too long...
Imagine you have two ducts (ducts 1 and 2) that merge into a single duct (duct 3). There is a fan located on duct 3 that needs to pull air through ducts 1, 2, and 3, and then exhaust it through duct 4. Both ducts 1 and 2 have obstructions that cause a pressure drop of 7 inches of water column...
I am a chemical engineer fresh out of college and have landed myself a job as a project engineer. Part of my job is spec-ing and ordering electrical parts like actuators, VFDs, proximity switches (pressure and level switches too), etc. I lack a lot of the basic knowledge when it comes to...
I am trying to make a pressure relief valve calculation in Excel for determining the minimum required area of discharge to get a desired mass flow rate. I am using the ACHIE relief valve sizing article and the example in it to validate my calculations. However, when I convert the metric units to...
I am currently working on a process that uses inert nitrogen (N₂) to purge organics from a tank. The organics are then fed through a process line into an oxidizer. Initially, the process line contains primarily organics, but as the tank empties, the process line becomes more nitrogen-rich. This...
I had a coworker once tell me there is a great textbook that has a list of flow coefficients for poppet valves, but he cannot remember the name or author of the textbook. If anyone knows of a textbook, or other source, where I can find these values, please let me know.
Below is an example of...
Here is a fictitious example to clarify my question.
Regarding the % composition of the mixture, what does it mean that propane and butane share the same area %?
My guess is that a certain percentage of propane and a certain percentage of butane make up the 15%. But, if that is the case, how...
Got a list of VOCs but have no solid method of determining the heating values (BTU/lb) or (BTU/scf).
Ethylene carbonate (EC)
Dimethyl carbonate (DMC)
Ethyl methyl carbonate (EMC)
Diethyl carbonate (DEC)
Propylene carbonate (PC)
Propyl propionate
Ethylene glycol (EG)

Propane has a mass flow rate of 9 lbs/hr and I am tasked with converting it to liters/hr. I chose to do the conversion two ways.
Method 1: 9lbs/hr *(21600 BTU/lbs) * (24000 BTU/liter)-1 = 8.1 liter/hr
Method 2: 9lbs/hr *(44.1 lb/lbmol)-1 * (379 scf/lbmol) * ((460+70)/530)*(14.7/(14.7+100))...
