PNNL has distillation capabilities ranging from systems that can process on the order of 1-liter/day to up 30-gallons/day of material. These capabilities include:
Laboratory-scale Distillation System
Wiped Film Distillation System
This intermediate scale is critical because it allows, for example, traditional fuel analysis to be conducted (e.g., RON or MON), so that the material can be compared to petroleum based fuels. Many of these analysis techniques require over 1-L of material, which can be achieved in a timely and efficient manner at this scale.
Skid-mounted Distillation System
This system is well-suited to produce gallon quantities of materials (e.g., ~30 gallons/day) that can then be used for more detailed analyses and/or engine testing, for example.
|Limitations||The wiped film system is currently limited to 200°C, but this temperature can be increased if the Teflon wiper blade assembly is replaced with carbon wiper blades. With this addition, the entire system is limited to a 490°C maximum working temperature. The minimum-sized sample is about 500 ml.|
|Unique aspects||This wide range of distillation capabilities enables one to progress through the fuels or products analyses/qualification process in an efficient manner. Smaller sample sizes are required for initial analytical tests, then larger quantities are typically required for more in-depth and rigorous testing as well as for engine testing.|
|Availability||There are no significant limitations on the system’s use and availability as long as the feedstock can be distilled and does not thermally polymerize.|
