@jrod_hirsch I also love when people use their own story of success against odds to try and downplay the struggles that other people have

@jrod_hirsch @andersoncooper The silver fox is indeed a legend

@jrod_hirsch Are beaches still open?

@CaninoZayas_P @OwenPorth @NU_ChemE They are polycarbonate chips that would be several cms in length/width, and a cm thick. The chips would then have a channel CNC milled into them. So, the cost in total for 600,000 units is comparable to most other unit operations needed for the process.

@alexC_Biochar @OwenPorth @NU_ChemE This kinetics model is just for R2 (the main reactor, or array of microreactors, that is boxed in the P&ID). We also developed equations for how R2's footprint and pumping power (estimated by pressure head losses) scales with microreactor dimensions and flow rate.

[Gavin Winter @gavin__winter]

@alexC_Biochar @OwenPorth @NU_ChemE We used experimentally-derived reaction rate constants published in literature to determine transesterification kinetics in our microreactor. For a given flow rate through the reactor and microreactor dimensions, exit concentrations for each species, purity, etc. were determined.

@CocoonitL @NU_ChemE Cool concept! I'm curious what your business model is, considering the hurdles you might have to deal with in terms of food safety. Would you license the technology/process to Cambridge Crops or are you looking to bring a product to market independently?

[Gavin Winter @gavin__winter]

@sofiakcatalina @MaryLouNadeau @katelynripley @paigekru @AlexisDubs Really nice experimental data. How did you determine your cost basis of $100/kWh? Was it comprised primarily of raw materials costs?

@ThomasJWebster1 @OwenPorth @NU_ChemE There will be an extensive solids filtering step. In terms of free fatty acid and moisture content (problematic components of feedstock), our acid pretreatment is pretty robust and any excess water would be washed out in the glycerol wash before base-catalyzed tranesterification

@richardhwest @OwenPorth @NU_ChemE 600,000 microreactor chips in parallel would fit in one or two shipping containers, and the estimated pumping power from pressure head losses is around 100 W (given our channel width/depth of 1200 um).
