Feedstock Parametric Study
A significant area of purchaser support is the Feedstock Parametric Study. The purpose of the study is to process a specific feedstock under optimal conditions to maximize project, product and process goals and objectives. Conrad Industries will expend the resources necessary to confirm and ensure project success.
Protocol and Objectives:
** Correlate project, process and economics
**Project goals: environment, regulatory, liability/opportunity
**Product goals: sampling and analysis protocol / analytical requirements / characterization and composition of gas, liquid, solids / quality and marketability
**Process goals: performance measurement / through put / ease of operation / material balance / yield maximization
**Determine process limitations and extraordinary advantages
**Understand depolymerization chemistry under the objective conditions
** Process Optimization
Process optimization involves the manipulation of (T)thru-put(feedrate), (T)temperature(severity), (T)turbulence and residence (T)time. The process heat transfer rate is dependent upon the interaction of the four "T's". All of the four "T's" can be controlled. Temperature is controlled through fuel and air adjustments to the burner system. Feedrate is controlled by adjusting the speed of the feeder. Turbulence and residence time are controlled by adjusting the rotational speed and direction of the feedstock conveying auger inside the reaction vessel. Each of the 4 “T’s” can be changed at will, but each are inextricably connected and any changes require a process stabilization period to attain steady state conditions.
The process is continually monitored and operating parameters are recorded, analyzed and combined with our operating experience to determine the degree and direction of future change.
