The stage-gate technique used for traditional chemical processes must be modified for bioenergy technologies. The approach developed for traditional chemical process industries (CPI) projects must be modified to account for challenges related to processing the fluids and handling the solids in bioenergy processes. The scaling factors in going from one scale to the next are an order of magnitude lower for bioenergy processes than for similar CPI processes, due to certain challenges. The stage-gate process divides the scale-up of a technology into stages, each successively larger in scale than the earlier. Source

Separation processes are an important component of chemical and petrochemical plants. In large facilities, gas/liquid, liquid/liquid, and gas/liquid/liquid separators can benefit from engineered internals such as coalescing plate packs, weirs, and baffles. In smaller pilot facilities, these internals can be difficult to employ due to size constraints. This session will discuss various approaches of designing and fabricating pilot scale separators that are effective without the benefit of internals available to their full-scale counterparts. The main focus will be on a recent redesign of a small scale three phase separator that has been proven to have less liquid carryover than earlier designs. Source

An overview of hazardous area designations and the electric motor features required for such areas are discussed. Motors for use in environments deemed Class I, Division 1, that is, presence of gaseous hydrocarbon, must be built and labeled as explosion-proof. In addition to having an explosion-proof enclosure, motors for use in Class I, Division 1 locations must not develop surface temperatures hot enough to cause spontaneous ignition of hazardous gases in the external atmosphere. Class II locations contain dust that is either electrically conductive or could be explosive when mixed with air. A totally enclosed, fan-cooled (TEFC) motor, or even an open, drip-proof (ODP) motor, may be used in a Division 2 environment, provided it does not have arc-producing brushes or switching mechanisms, which could act as ignition sources. Safety should be a primary concern when choosing a motor for use in a hazardous environment. Source

The recommended approach for scaling bioenergy and biofuels technology follows a similar stage gate process to that used in traditional Chemical Process Industry (CPI) processes. However, processing of solids in bioenergy applications leads to some subtle differences and unique challenges that are to be considered. This is an abstract of a paper presented at the 2013 AIChE Spring Meeting & 9th Global Congress on Process Safety (San Antonio, TX 4/28-5/2/2013). Source
