New Perspective -“Lowest Cost” Energy From
Vast Biomass 33, SCW, Wet Air Oxidation
• -->> cont; •3 MAINLY WASTE: ✔ 3h UnConven'onal Liquefac'on:
v-Sub-SuperCri'cal W.
• SCW is re-surging quietly in mainstream Japan: eg sewage water sludge superheated
steam gasifica;on(Meta Water, Chugoku Denryoku+), Also used for AD pretreatment
of solid or liquid waste(Gekkeikan+). Oil industry can benefit by SCW cracking:
previously imprac;cal tars, low grade bitumen - oil sand - extra heavy crude oil
upgrading with possibly most effec;ve EOR, or Refinery Residue
Upgrading/cracking/visbreaking with liPle to no coke remaining(Inhibit asphaltene
polymeriza;on): ◎(JOGMEC+), Also dras;cally cut cost of Synthe;c Crude Oil(SCO)
produc;on(no diluent use) to enable low cost pipeline transporta;on of oilsand
(Syncrde+)
• Wet Air Oxida,on is used for WasteWater treatment: regular municipal, industrial, oil
industry caus;c water etc. Slightly different from & more "primi;ve" mechanics than
SubCri;cal water process by use of bubbling reactor to inject oxygen/air with lower
pressure than SubCri;cal water method, also generates slightly higher amount of
emission than SCW(s;ll minimum), ◎(Veolia Water Athos, Bertrams ch, Wetox nz,
Merichem - Kenox+), Used as pretreatment ◎(Granit Technologies SA+), but note
many SCW oxida;on(SCWO) process also injects oxygen.
