Stan Mayfield Demonstration Biorefinery

Campaign Summaries


The Stan Mayfield Biorefinery conducted a series of campaigns during the four years it was in operation. Each campaign involved continuous operation and processing of either sugarcane bagasse or sorghum bagasse into cellulosic ethanol, typically lasting 7-10 days in length. A total of 23 campaigns were conducted to assess different variables and ultimately optimize the bioprocess. At the end of each campaign, process engineers would provide a summary for internal documentation and grant reporting purposes.

Preventative Maintenance


The Biorefinery's process engineers were tasked with preventing disruptions in operation and preserving worker safety through diligent surveying and maintenance of the various equipment within the thermochemical pretreatment system. The biomass pretreatment system was a highly complex series of equipment that operated under high pressure with corrosive chemicals, thereby making it prone to malfunction. A series of data tracking tools were developed to be routinely utilized by the process engineers. The data provided herein are not entirely complete, and empty cells are denoted by NA.

Process & Instrumentation Diagrams


Process & Instrumentation Diagrams (PIDs) show how different pieces of equipment are connected internally and externally to various unit operations. PIDs use symbols, flow directions, safety measures, control systems, pressure ratings, and other details to provide process engineers and operators with the information necessary to startup, maintain, troubleshoot, or shutdown various procedures.
