  1. 1. Design of a solvent recovery system in a pharmaceutical manufacturing plant

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :SHASHANK BHANDARI; [2016]
    Nyckelord :Batch distillation; liquid-liquid extraction; pressure swing distillation; pharmaceutical manufacturing; sustainable development;

    Sammanfattning : Solvents play a crucial role in the Active Pharmaceutical Ingredient (API) manufacturing and are used in large quantities. Most of the industries incinerate the waste solvents or send it to waste management companies for destruction to avoid waste handling and cross-contamination. LÄS MER

  3. 2. Combined production of bioethanol and biogas from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Victor Gustafson; [2015]
    Nyckelord :lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Sammanfattning : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. LÄS MER

  4. 3. Evaluation of a batch process by means of batch statistical process control and system identification

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Sebastian Larsson; Eric Grundén; [2015]
    Nyckelord :System identification; Sub space identification; Kalman filter; Batch statistical process control; Partial least squares; Batch process; Technology and Engineering;

    Sammanfattning : Batch processes play an important role in the production of high quality specialty chemicals. Examples include the production of polymers, pharmaceuticals and formulated products. In this master thesis, the study of transformation of materials, by batch distillation and mixing is studied.

  5. 4. Teknisk utvärdering av en ny miljövänlig förbehandlingsmetod av biomassaavfall med utspädd salpetersyra

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Li Zhi; Oliver Murgårdh; [2012]
    Nyckelord :lignin; cellulosic ethanol; sweet liquor; pre-treatment; dilute nitric acid pulping; SSF; SHF; cellic ctec2; yeast; NABC; bio-refining;

    Sammanfattning : Bio-refining of renewable resources such as waste biomass into value added products has increased rapidly over the last decades. The aim is to find new environmentally friendly yet economically feasible ways of replacing current utilization of non renewable resources. LÄS MER

  7. 5. Modelling and Optimization of Batch Distillation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Anna Klingberg; [2000]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The detailed dynamic modelling, simulation and optimisation of a batch distillation process at Bayer AG is presented. The model considers a mixture of 10 components separated in a 40 tray column. Simulations performed in the process modelling tool gPROMS proved that the model gives a very accurate description of the process behaviour. LÄS MER
