Velocys Microchannel Technology - NegativesSmall dimension coolant channels impose boiler feed waterspecifications equal to a typical syngas generation unit spec– BFW must also be filteredSmall catalyst particles and high gas feed rates make the pressuredrop the same as for conventional tubular reactorsShort “tube” length results in only partial poison guard bed effect26
Velocys Microchannel Technology–ImplicationsVelocys microchannel technology combines the best of fixed and slurrybubble column reactor performance with very few of the negatives– Isothermal performance without catalyst/wax separation issues– High on-stream factor without complicated and expensive regeneration unit– High upset AND shutdown robustness– Very low recycle to fresh feed ratio requirements while achieving high conversionVelocys microchannel technology uniquely suitable for plants
