This paper builds a quantitative thermodynamic model for the microbial hydrolysis process (MHP, which uses Caldicellulosiruptor bescii at 75°C pre-digestion) producing biogas from 5-10% aqueous suspension of dairy manure (naturally buffered near pH 7.8 by ammonium bicarbonate) anaerobic digestion with mix acetoclastic and syntrophic methanogenesis. Standard Gibbs energy changes were calculated ...

Abstract This paper describes a maintenance scheduling model for digester banks. Digester banks are network-connected assets that lie on the critical path of Bayer process, chemical refinement process converts bauxite ore into alumina. The require different activities at due times. Furthermore, schedule is subject to production-related constraints and resource limitations. Given complexity larg...

A strategy for detection of feedstock variations in a continuous pulp digester is presented. A Gaussian Radial Basis Function Neural Network is used to infer these unmeasured variations. The absence of plant data motivates the development of training set data. The efficiency and limitation of the approach is demonstrated with a first principles model.

A nonlinear anaerobic digester model of wastewater treatment plants is considered. The stabilizability of the dynamic system is studied and a continuous stabilizing feedback, depending only on an online measurable variable, is proposed. Computer simulations are carried out in Maple to illustrate the theoretical results.

Clostridium sp. Bc-iso-3 is a cellulolytic strain isolated from a Swedish industrial-scale biogas digester. Here, we present the draft genome sequence of this strain, which consists of four contigs with a total length of 4,327,139 bp and an average coverage of 312.97×.
