Uncertainty in techno-economic estimates of cellulosic ethanol production due to experimental measurement uncertainty

UNLABELLED BACKGROUND Cost-effective production of lignocellulosic biofuels remains a major financial and technical challenge at the industrial scale. A critical tool in biofuels process development is the techno-economic (TE) model, which calculates biofuel production costs using a process model and an economic model. The process model solves mass and energy balances for each unit, and the ...

How to Describe Measurement Uncertainty and Uncertainty of Expert Estimates?

Measurement and expert estimates are never absolutely accurate. Thus, when we know the result M(u) of measurement or expert estimate, the actual value A(u) of the corresponding quantity may be somewhat different from M(u). In practical applications, it is desirable to know how different it can be, i.e., what are the bounds f(M(u)) ≤ A(u) ≤ g(M(u)). Ideally, we would like to know the tightest bo...

Numerical modeling of economic uncertainty

Representation and modeling of economic uncertainty is addressed by different modeling methods, namely stochastic variables and probabilities, interval analysis, and fuzzy numbers, in particular triple estimates. Fo-cusing on discounted cash flow analysis numerical results are presented, comparisons are made between alter-native modeling methods, and characteristics of the methods are discussed.

Techno-economic and uncertainty analysis of fast pyrolysis and gasification for biofuel production

This thesis consists of uncertainty and techno-economic studies of two different biofuels production pathways (catalytic pyrolysis and gasification). The objective of this paper is to obtain a side-by-side techno-economic comparison of in situ and ex situ catalytic pyrolysis, and gasification state-of-technology and target scenarios that addresses both sensitivity and uncertainty analysis in th...

Uncertainty analysis and global sensitivity analysis of techno-economic assessments for biodiesel production.

There are various uncertain parameters in the techno-economic assessments (TEAs) of biodiesel production, including capital cost, interest rate, feedstock price, maintenance rate, biodiesel conversion efficiency, glycerol price and operating cost. However, fewer studies focus on the influence of these parameters on TEAs. This paper investigated the effects of these parameters on the life cycle ...
