An assessment of operating conditions for supercritical water gasification and safety issues

The research paper presented here describes experimental investigations of Black Liquor Supercritical Water Gasification in a continuous Plug Flow Reactor system. Operating conditions heavily affects the gasification yields within the process. Nevertheless, an important issue in SCWG is the possible deposition of tar, char and inorganic compounds with subsequent plugging of the reactor. Reactions of re-polymerization are taken into account in regards to the results obtained. Important considerations are given here concerning the design and operation of high pressure reactor systems aimed at SCWG of biomass. Operational issues are seldom taken into account in this kind of investigations.
