[Gasification] 3 injured in Fortum bio-oil plant explosion

[John Miedema]

Hello Roland, 

Thank you for the information about your process.
Is your process a "slow" pyrolysis reaction? 

If so the bio- oil is a substantially different product then the "fast" pyrolysis oil that some companies are trying to convert to motor fuel . 

Am I correct that you are combusting this oil for thermal energy and not attempting to run a motor ?

Are you making an aqueous phase also? If so, are you finding use for this "wood vinegar" ?

I have a gasification/ pyrolytic hybrid that I built and can make a slow pyro oil in my process. I am currently pouring the oil onto some of  the feedstock going into the gasifier  and boosting my fuel btu ( and getting rid of that oil).

In any case for most industrial charcoal manufacturers. In our demonstration plant, employing our new charcoal manufacturing technology, we make pyrolysis oil in addition to charcoal. Ball park indications, recalculated to the dry basis of all materials involved (dry basis outputs / dry basis inputs, and changing with process temperature management): 38 m% dry charcoal, 15 m% liquid, 47 m% gas. All of the gas can be combusted for heat and/or power, but it would be a waste to do the same with the liquid.

In our case we wanted to be able to at least use part of the pyrolysis liquid to sustain our carbonisation process, but not immediately upon production. Rather postponed, and only when needed (the rest of the liquid may find other uses anyway). So, we like pyrolysis oil as an energy buffer.
