Flash Drying of Recycled Paper Pulp in a Mechanically Agitated Fluidized Bed
(Åbo Akademi, 2020)
Flash drying of pulp is an interesting option for drying of market pulp, mainly due to its high thermal efficiency and relatively low operating and capital costs. Typical flash dryers consist of a series of high drying ...
Effect of Dust Sintering on Fouling of Recovery Boiler Flue Gas Ducting
(2021)
Recovery boilers today are 100 times the capacity of the original design. The fuel, black liquor, used in recovery boilers has also changed. To improve the efficiency of the boiler, the fuel contains less water. Increased ...
Degradation of polydimethylsiloxane in simulated industrial process environments
(2021)
Polydimethylsiloxane (PDMS) is commonly used in the Kraft process as an anti-foaming agent, which is added during the pulp-washing stage, where the pulp is separated from the black liquor. Crude tall oil (CTO) is later ...
The Potential Use of LNG in SSAB Raahe Steelworks
(2020)
Steel has been produced for thousands of years, but its extensive, industrial use began during the industrialization, with the introduction of more efficient production methods, such as the blast furnace. The global ...
A Study of Glucose Transformation to Lactic acid and Methyl lactate
(2021)
Lactic acid and methyl lactate are platform molecules that hold great potential within the biorefinery industry. They are currently produced through a combination of enzymatic and fermentation processes within the industry, ...
Thermal degradation and stabilization of HVDC power cable insulation materials based on polypropylene
(2022)
In this work, a series of antioxidant formulations’ effectiveness for propylene copolymers intended to be used as insulation materials for HVDC cables has been eval-uated by subjecting the polymer samples to forced-air ...
