Roni҂ † Biomass Analysis, Idaho National Laboratory, PO Box 1625, MS 3570, Idaho Falls, ID, USA ꜝ Chemical Systems, Idaho National Laboratory, PO Box 1625, MS 3570, Idaho Falls, ID, USA ‡Mechanical Systems Design and Control, Idaho National Laboratory, PO Box 1625, MS 3570, Idaho Falls, ID, USA ҂Advanced Data Analytics, Idaho National Laboratory, PO Box 1625, MS 3570, Idaho Falls, ID, USA KEYWORDS: Preprocessing, Discrete Event Simulation, Throughput, Quality, Operational Reliability ABSTRACT Operational inefficiencies in biomass handling and preprocessing due to wide variability in physical and compositional attributes characteristic of biomass supply systems threaten the development of a sustainable bioeconomy. In this study we describe the application of discrete event simulation to conduct feedstock property dependent throughput analysis of a conventional corn stover supply logistics-preprocessing-conversion system, utilizing pilot scale preprocessing equipment data and experiential information on failure frequency and down time for biorefinery scale preprocessing equipment. A new metric, “operational reliability,” is defined that assesses the composite impacts of feedstock quality on dynamic operational efficiency and productivity. Based on corn stover compositional variability and changes during harvest, collection and storage, Supply Logistics delivered stover meeting quality specifications only 11.5% of the time. The Preprocessing subsystem achieved an average of 30.3% of nameplate capacity with 28.6% of the material meeting specification, giving a modeled operational reliability of 8.68%. The dynamic delivered cost of the corn stover at the conversion reactor throat varied from $100.19-$549.95/dry Mg, with a mean of $208.67 and standard deviation of $93.19/dry Mg (all in 2016$). The bottlenecks in the overall supply system were shown to reside within Preprocessing and to be a direct result of poor performance of existing bale storage designs. Hence, active management of corn stover quality prior to reaching Preprocessing could contribute significantly to both improved operability and improved yield.

POTR RO Water
by Crawley, Lindsey R 11 Nov '19

11 Nov '19

The new system has been installed but the plumber informs me that the building's reservoir tank is not filling. He has shut off the inlet to that tank. He suspects that there is still an open faucet or supply. While I plan to walk through all POTR labs, please take a moment to check your own workspace. Is it possible that a faucet inside a hood or waterbath has been left on? Please review ASAP and report to me any necessary update. Thanks. /////////////////////////////////////////////////////////// Lindsey Crawley Lab Manager Laboratory of Renewable Resources Engineering http://www.purdue.edu/lorre Department of Ag. and Bio.

LORRE Seminar - 11/07
by Engelberth, Abigail S 06 Nov '19

06 Nov '19

Reminder that we will have LORRE seminar tomorrow at 9:30 AM in POTR 234 for a presentation from Jessica Zuponcic and Jonathan Overton to practice their respective talks for AIChE. Reminder that we will extend the duration of our seminar and will meet from 9:30-11:30. Please come for as long as you are able. I realize that some of you may have commitments beyond the normal 10:30 stopping point. Please stay if you are able. The seminar schedule is attached and can be accessed via this link<https://docs.google.com/spreadsheets/d/1uBhyQPcpk4jHGfN4eg731Duo1vQFXy6ddY0…>. We will not meet next week as many from our lab will still be at or will be traveling back from AIChE.
