  1. 1. Computer-aided optimization of complex processes in production systems and urban environments

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Mikael Yamanee-Nolin; [2020-04-14]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; modeling; simulation; complex processes; process systems engineering; preparative chromatography; blue-green systems;

    Abstract : Complex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. READ MORE

  2. 2. Integration of thermochemical processes with existing waste management industries to enhance biomethane production

    University dissertation from Västerås : Mälardalen University

    Author : Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Yang Weihong; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygeneration; process integration; integrated biorefineries; biomethane; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In most waste management industries, waste is separated into different fractions, each of which is treated with suitable processes. Established technologies such as waste combustion for combined heat and power (CHP) production and biomethane production through anaerobic digestion (AD) of biodegradable waste work fine as standalone processes.
