berndj: yes linde
<
Sync>
but I'm also planning on a autocascading one
<
berndj>
what's you take on the DIY quotient of a linde liquefier?
<
Sync>
you need three compressors and a few HXs
<
berndj>
AFAICT it's the heat exchangers that are probably the bottleneck
<
berndj>
why three?
<
Sync>
I want to keep the headpresure on the nitrogen down
<
berndj>
you don't HAVE to return the unliquefied gas into the cycle, no
<
Sync>
so I need a cascade to cool the hot gas
<
berndj>
what sort of pressure do you want to work with?
<
Sync>
well I have a compressor that will do 150bar
