Analysis of wood chip combustion system for hot air generation in the industrial drying process

Rajika, JKAT [Thesis-Full-text]

A two-dimensional steady state packed bed CFD model is developed for the combustion of wood chip in a moving grate.The model is validated using an industrial moving bed hot air generator used in Tea industry.Various ...
Application of nanoclay on polyester fabrics as a bio-inspired approach to improve moisture management

Abeywardena, SBY [Thesis-Full-text]

Bio-inspired and biomimetic surface modifications are identified as one of the fascinating areas of research. In this study, nature’s way of cooling elephants’ body temperature using mud bathing was mimicked to create ...
Application of polyethylene terephthalate scraps for the manufacturing long oil alkyd resin

Darshana, LAP [Thesis-Abstract]

A new aspect of work that covers Polyethylene terephthalate (PET) waste recycling and application in coating industry is presented through this report. It was shown that chemical recycled PET can be used in the manufacturing ...
Assessment of environmental impact for accidental release of heavy gas

Gunawardena, YN [Thesis-Full-text]

An air dispersion model can be used to mathematically simulate air pollutants dispersion in the ambient atmosphere. These dispersion results can be used to predict their environmental impact, concentrations and movement. ...
Assessment of the feasibility of co-production of fucoxanthin, omega-3 fatty acids and bioethanol from marine microalgae

Premarathne R G M M [Thesis-Abstract]

The marine microalga Tisochrysis lutea is renowned for its ability to synthesize fucoxanthin and docosahexaenoic acid (DHA), which are nutritionally valuable high- value compounds. Although numerous studies in literature ...
Bacterial cellulose production by acetobacter xylinum in aerated, agitated and attached system

Dissanayake, DMSC [Thesis-Abstract]

Cellulose is the most common biopolymer on earth and has been identified as a major building material of all plants. It is common not only in the higher order plants, but also in microorganisms. Plant Cellulose formed to ...
Bio methanation and composting for managing sugar processing waste

Ariyaratne, WKH [Thesis-Abstract]

In Sri Lanka, two integrated sugar cane based sugar plants cum distilleries are running with satisfying around 12% sugar requirement of the country. As the other countries, we are also facing the waste disposal problem of ...
Biological removal of sulfurous pollutants in skim latex wastewater

Samarathunga IR [Thesis-Full-text]

Skim Latex Wastewater (SLW) contains high concentrations of sulfate, together with organic matter and nitrogenous compounds such as Ammonia and protein. High concentrated sulfuric acid is added in coagulation process to ...
CFD modeling of a centrifuge for oil - water separation

Thilakarathna, HGSM [Thesis-Full-text]

Centrifugation is an efficient, economical and environmentally friendly method to remove un-desirable water content from oil and water mixtures and separate out the desired oil content.Moreover, the disc stack centrifuges ...
Characterization and evaluation of starch xanthide encased powdered natural rubber

Maduwage, S [Thesis-Abstract]

Rubber as a free-flowing powder, is essential in order to stream line the manufacturing processes of rubber goods. The previous works noted the importance of using powdered rubber as a competitive raw material for continuous ...
Characterization of calcium carbonate filled natural rubber - low density polyethylene blends prepared with a titanate coupling agent

Sampath WDM [Thesis-Full-text]

The aim of this study was to develop reactive blends from natural rubber (NR) and low density polyethylene (LDPE) with acceptable physico-mechanical properties. NR and LDPE blends at different blend ratios were produced ...
Chemical leasing and nanotechnology for agriculture sector

Edrisinghe, LGLM [Thesis-Abstract]

During recent years the service-oriented business approach of Chemical Leasing has been researched and implemented at various companies of different industry sectors around the globe. The novel business model promotes ...
Chemical modification of rubber waste and characterization of their blends with natural rubber

Edirisinghe, DG [Thesis-Abstract]

Ground rubber tyre (GRT) produced by recycling of tyre waste or rejects is used as a filler in the manufacture of tyre components, mainly to reduce the cost. Rubber matrix-GRT compositions generally exhibit poor mechanical ...
Chemical process route selection based on assessment of inherent environmental hazard, occupational health and safety

Warnasooriya, S [Thesis-Abstract]

Chemical process route selection is one of the main design decisions that needs to be taken during the preliminary stages of chemical plant design and development. A chemical process route is considered as the raw materials ...
Climate change impact on the spatial distribution of droughts in Kirindi oya and Maduru oya dry zone river basins in Sri Lanka

Wijekoon, WMRTY [Thesis-Full-text]
