  1. 1. Assessing the suitability of using the by-product Petrit-E from steel production as agricultural fertilizer

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Eva Galyas; [2022]
    Keywords : steel slag; fertilizer; soil; leaching test;

    Abstract : Due to the growing population, waste generation and food supply industries need to move towards a circular economy and take advantage of by-products. Metallurgical slag is a main by-product during steel production which contains several valuable minerals and can be used for several further applications, including water purification and agriculture.

  3. 2. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonsson; Anton Andersson; [2021]
    Keywords : Vibratory driving; sheet pile; Technology and Engineering;

    Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

    Abstract : Decades  ago,  1  ton  of  steel  required  80  kg  of  refractory  material.  While  the  scenario  has completely changed over the years. Today, 1 ton of steel needs approximately 11 kg of refractory material   depending   on   the   steelworks. READ MORE

  6. 5. The Effect of Calcium on Delignification in Kraft Cooking of Eucalyptus

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Eashwara Raju Senthilkumar; [2019]
    Keywords : Delignification; Carbohydrates; Lignin; Yield; Calcium; Delignifiering; Kolhydrater; Lignin; Utbyte; Kalcium;

    Abstract : Delignifiering under sulfat koket innefattar både kemisk nedbrytning och fysisk upplösning av lignin, för vilket närvaron av oorganiska salter, oorganiska anjoner samt oorganiska katjoner (sammantaget benämnda som "Non-process elements", NPEs på engelska) kan ha inverkan på delignifieringens hastighet. Tidigare studier har funnit att ved med högt kalciuminnehåll är svårdelignifierad och att kalcium har potentiell inverkan på ligninlöslighet och kappatal. READ MORE
