Researching energy requirement of alternative systems, Cryomation is freezing the body with liquid nitrogen till -196 degrees Celsius and fragmenting the corpse to pieces and dry freezing it to remove moisture and bury the remains.
Why Buy an On-site Nitrogen Generating System?
The answer is simple. You can lower your ongoing nitrogen costs by up to 90% depending on the application. There are not too many technologies out there that will achieve those types of cost savings.
The following is a typical range in cost of various types of conventional sources of gas supply in the North American marketplace:
cylinder / nitrogen
$3.00 – $15.00 per M3
liquid dewar / nitrogen
$0.70 – $1.50 per M3
bulk liquid / nitrogen
$0.15 – $0.75 per M3
Depending on nitrogen purity required, geographic location and associated electricity costs, typical operating costs (energy and maintenance) for generating nitrogen on site can be less than $0.02 per M3 based on nitrogen purities of 95 – 97%. http://www.adgastech.com/Nitrogen-Costs.aspx
Liquid phase, nitrogen
Liquid density (1.013 bar at boiling point) : 808.607 kg/m3
Latent heat of vaporization (1.013 bar at boiling point) : 198.38 KJ/kg
808 kg X 198 KJ = 159984 KJ = 160 MJ
1Kwh = 3,6 MJ thus 160/3,6 = 44,4 Kwh energy has to been put in condensing and cooling of this cubic meter of nitrogen gas assuming a Kwh price of $0,10 = $4,44 something strange is happening over there!
