Advanced Control for Hydrogen Pyrolysis Installations

Biomass pyrolysis oils for hydrogen production using chemical looping reforming

This study considers the feasibility of using highly oxygenated and volatile pyrolysis oils from biomass wastes as sustainable liquid fuels for conversion to a hydrogen-rich syngas using the chemical looping reforming process in a packed bed. Pine oil and palm empty fruit bunches oil‘EFB’were investigated with a Ni/Al2O3 catalyst doubling as oxygen transfer material (OTM). The effect of molar s...

Integrated Control and Diagnostic System Architectures for Future Installations

Control and Optimization for Steel Plant Preheating Installations

The paper presents the results of the research performed by the authors on control systems and optimization for the operating process of the heating installations from the blast furnace at a steel plant. This system was developed on two relevant levels interconnected in a hierarchical control structure. The acquisition and control level using specialized microcontrollers was implemented. The su...

Advanced Oxidation to Reduce Emissions in Foundries from Coal Pyrolysis

Foundries employ green sand molds, which contain coal, silica sand, clay, water, and core binders. This represents one of the largest non-combustion users of coal. When the coal experiences high temperature during the metal casting process, it undergoes pyrolysis reactions and can generate significant amounts of volatile organic compounds. Some of the compounds are released as hazardous air pol...

Experience Report: Exploiting Advanced Database Optimization Features for Large-Scale SAP R/3 Installations

The database volumes of enterprise resource planning (ERP) systems like SAP R/3 are growing at a tremendous rate and some of them have already reached a size of several Terabytes. OLTP (Online Transaction Processing) databases of this size are hard to maintain and tend to perform poorly. Therefore most database vendors have implemented new features like horizontal partitioning to optimize such ...
