First of all, consider that natural gas is a mixture of different compounds. Look for the ISO standard NG composition as vehicle fuel, sorry but I don't remember its number.
To quickly obtain the mass in the cylinder at various pressures I'd rather use the corresponding states...
dcasto and djv
if we push the analysis further, also a roller bearing, a flexible coupling and (as you note) belts could be ignition sources.
CSA certified devices or systems, from what I know, are not considered in ATEX directive.
The risk of going too far with the risk assessment and to...
dcasto,
I agree with you that reasonably, with enough ventilation, protected ignition system and (I add) insulated exhausts plus protected (EEx-i for example) instrumentation on the engine itself, there is no need of any walls or seals. I know that most of gas engine/compressor packages have...
Thank you David
I was thinking for a long time that the problem was quite tough under this aspect.
Anyway, if I decide to go with the two rooms approach I will consider both gensets and also cardanic shafts in the effort to minimize alignement issues.
I must admit that I prefer the one-skid...
Hi to all
I am a designer in a medium-size italian CNG recip compressor manufacturer company.
We are compressor manufacturer and packager at the same time: all our compressor (till now) have been driven by small low voltage electric motors (400V 37-400 kW).
Now we decided to offer our customers...
First of all thank you all for your interest.
We checked some times ago interstage cooler and it seemed ok. One of the first things we checked was also the correct closing of 3rd and 4th stage bypass at startup...
@ monaco8774: compressor does not take gas from a subsea reservoir, but from a...
Hi to all, I am new to this forum!
I briefly present myself: I am an european reciprocating compressor designer: our compressors are specifically designed for CNG service, but also fit good for a wide range of applications (nitrogen, hydrogen, biogas, and other). Rated power ranges, depending...
