Looking at general guidance for separation distances for hydrogen systems and skimming through the NFPA hydrogen guidance. For Gaseous hydrogen storage, NFPA 2 and 55 have the same tables which relate pressure, pipe diameter and hazard category to minimum separation distance. The tables that are...
Thanks everyone, I appreciate that cost estimates should be treated with caution. My question was more around why the same source appears to have two methods that are so significantly inconsistent. These costs wouldn't be used in anything more stringent than Class 5 (or Class 4 at a pinch if...
Using Woods 'Rules of Thumb in Engineering Practice' (2007) Appendix D cost estimation approach (easily available to download online as pdf - won't link as probably not kosher).
Section D.2 / Page 377 suggests there are two ways to estimate the Bare Module (BM) cost correcting for L+M*, however...
I've done more than my fair share of FEEDs and Detailed Design and its something that I've never quite got an answer to.
I'm talking about specifically showing the control block (usually) showing the current to pneumatic line to a control valve.
Some projects do show it, some don't. Some don't...
Does anyone have any suggestions for good resources specifically for LNG equipment (not overall plant) cost estimation?
Specifically for rotating equipment (compressors, pumps) and full containment tanks.
I'm wary of using established estimation generic curves because of the LNG cryogenic...
Does anyone know of a good resource/design guideline/calc for the design of a LNG gasification terminal boil off recondenser?
Specifically a typical top packed bed co current type.
Been scouring the web and not finding much. I appreciate the specific design is fairly proprietary, but this is...
Specifically concerned about oxygen contamination.
From what I've read it doesn't appear to be that critical, but even a rough rule of thumb (with a reference) would be helpful.
