  1. 1. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Eimantas Gladkauskas; [2019]
    Nyckelord :Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Sammanfattning : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).

  2. 2. Shaft stability analysis of the RBR S5 : Stabilitetsanalys av axel tillhörande RBR S5

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Simon Lindgren; [2019]
    Nyckelord :;

    Sammanfattning : This bachelor’s thesis work completed for Spinchem intend to calculate and simulate the deflectionof a rotating shaft belonging to the rotating bed reactor S5, RBR S5. The shaft is the part thattransfers the torsion to the RBR S5 and is the part that will behave as a spring due to the rotationalvelocity. LÄS MER

  3. 3. Development of a Mobile Reactor for Large Scale Water Treatment

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alexander Berggren; [2019]
    Nyckelord :Water treatment; Mobile reactor; Autopilot; Rotating Bed Reactor;

    Sammanfattning : Water pollution is one of many environmental problems that currently exists and inadequate treatment of industrial wastewater is contributing to further pollution. SpinChem AB's Rotating Bed Reactor (RBR) technology offers the possibility of water treatment by carrying out reactions between a solution and a solid phase. LÄS MER

  4. 4. Remediation of Contaminated Groundwater Using a SpinChem® Rotating Bed Reactor : Competitive Sorption of Metal(loid)s in Complex Solutions under Varying Geochemical Conditions

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Pär Alapää; [2018]
    Nyckelord :Groundwater Remediation; Competitive Sorption; SpinChem;

    Sammanfattning : The potential of utilizing a new form of chemical processing technology called SpinChem® Rotating Bed Reactor (RBR), in combination with different reactive materials, for the purpose of remediating multi-contaminated aquifers under changing environmental conditions, was investigated using laboratory studies and geochemical models. Four different reactive materials, or combinations thereof, were tested: heat-treated peat powder combined with zero-valent iron (ZVI); IronPeat, which consists of peat powder coated with a ferriferous hydrosol (FFH); and a powdered steel waste product.

  5. 5. Modelling adsorption rate in a rotating bed reactor

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jonathan Jonsson; [2018]
    Nyckelord :computational fluid dynamics; fluid mechanics; cfd;

    Sammanfattning : SpinChem AB designs rotating bed reactors (RBR:s) that are used to conduct reactions between solid and liquid phase. In this work a model have been developed that predicts the performance of the S2 RBR. Coupled with simulations the model could be used to improve current and future RBR designs. LÄS MER
