Der volle Inhalt der QuelleThis Ph.D. work is a contribution for understanding the fouling in plate heat exchangers (PHE) during the heat treatment of whey protein solutions. This work aims at establishing the relationship between the composition of the different whey protein solutions (β-lactoglobulin content (β-lg) and calcium), their denaturation behaviour and their ability to foul the hot surfaces of the PHE.This study showed the strong impact of the calcium content and the calcium/protein molar ratio on the β-lg thermal denaturation mechanisms, the distributions of the deposit fouling, deposit formation dynamics and the structure of the first deposit layers.The determination of the β-lg denaturation kinetic constants and the knowledge of the thermal profile allowed to simulate the concentration profiles of the different β-lg species (native, unfolded and aggregated) along the PHE and to study the correlation between the dry deposit mass of and the amount of denatured β-lg in the PHE. This simulation highlighted the negligible role of the aggregates in the fouling mechanisms and both the influence of the unfolded species and the calcium content on the distribution of protein deposition. Finally, a new correlation between the distribution of dry deposit masses in each channel of the PHE and the denaturation kinetic parameters was determined for each studied protein solution, showing thus that chemical reaction engineering approaches are requested for predicting proteinaceous fouling

Der volle Inhalt der QuelleThe present work is a contribution to better understand the influence of casein micelles on the fouling of serum whey protein solutions. In particular, experimental and numerical approaches have been carried out, at laboratory and pilot scales, to describe denaturation phenomena and better understand the role of calcium in fouling mechanisms. First of all, the effect of casein/whey mass ratio on the whey protein fouling performance was investigated in a pilot-scale PHE. The total fouling deposit mass drop significantly with the addition of casein, resulting in a minimum value located at Casein/WPI of 0.2. Exceeding this critical ratio, fouling deposit increased with elevated casein concentrations. The deposit mass drop (Casein/WPI ≤ 0.2) is unlikely to be linked to the thermal denaturation of BLG and is more probably due to the change in mineral interactions introduced by casein. The increased fouling mass (Casein/WPI ≥ 0.2) was attributed to a co-precipitation of BLG-casein complex that enhances the fouling. It is proposed that micellar casein change deeply the calcium balance and the content of CaP nanocluster modifies sharply the interactions which occur between protein species (BLG, caseins) and mineral elements (ionic calcium, Ca-P) thereby affecting the protein denaturation and fouling behavior. A novel kinetic model concerning thermal unfolding and aggregation of BLG was established. This model interprets mathematically the break-slope behavior in the Arrhenius plot and provides detailed thermodynamic information for both unfolding and aggregation processes. Based on this model, it was confirmed that ionic calcium has a protective role on the thermal unfolding of BLG at low temperature. In contrast, at higher temperatures, calcium promotes aggregation and the formation of unfolded BLG species. A bench-scale fouling rig was built to perform whey protein fouling experiments in a laminar regime. A realistic 3D CFD model was achieved to simulate both the bulk and surface reactions. Results showed a linear relationship between the deposition pre-exponential factor and calcium concentration, suggesting the fouling is built in such a pattern that only one calcium ion per BLG molecule is involved. Calcium was confirmed to be essential to fouling growth with significant effects both on the thermal denaturation and deposition processes. Finally, the effect of casein/whey ratio on the whey protein fouling was investigated in the laboratory-scale fouling device. Results revealed a similar effect of casein on fouling mitigation as those found in the pilot plant. However, in this case, the fouling was suppressed and maintained at a low extent even at high Casein/WPI ratios (up to 4). The presence of individual caseins in the serum phase was considered to be responsible for this fouling mitigation probably through their chaperon-like activities. However, when the pH of the fouling solution is set at 6.6, casein is shown to lose its fouling-mitigating effect at higher ratios. This behavior is related to its weak ability of casein micelle to control ionic calcium in the serum phase at lower pH, resulting in higher calcium concentration facilitating BLG denaturation and deposition accumulation. A lower amount of dissociated caseins in the serum phase at pH 6.6 could also explain the increase in fouling mass because they are not in sufficient concentration to perform chaperone-like functions

Der volle Inhalt der QuelleThis thesis is about biomineralisation, the process by which living beings manage to direct the precipitation of minerals present in their environment to make materials useful for the survival of the species in question. Biomineralization is an extremely complex phenomenon involving genetic regulation and the involvement of proteins to trigger mineralization at specific locations. It happens however that it escapes the control of the living organism, then leading to various pathologies. This is the case, for example, when calcifications called kidney stones are formed inside the kidneys. From a certain size, a renal calculus becomes pathological and requires hospital care. The pathology is commonly called urolithiasis. It is established that calcium oxalates, and more particularly the monohydrate (Calcium Oxalate Monohydrate, COM or whewellite) and dihydrate (Calcium Oxalate Dihydrate, COD or Weddellite) phases, make up the majority of kidney stones. The environment, and especially food, is a key factor influencing the formation and composition of kidney stones. Currently, the treatments consist mainly of an injection of analgesics and the ejection of the calculation by the natural channels. If necessary, surgery is performed. Doctors are looking for drugs / treatments that can potentially prevent the formation of kidney stones

Der volle Inhalt der QuelleBlast furnace slags are a co-product of the metallurgical industry, used in composite cements (CEM II & III) as a partial substitution for Portland clinker and recognized in particular for their advantages in terms of lowering the heat of hydration, increased durability performance and reduced carbon footprint of concrete. Although achieving ultimate mechanical performance comparable to or better than Portland cement (CEM I), binders offering high levels of slag see the development of their mechanical strength greatly slowed down. This phenomenon is explained by a lower reactivity of the slag which requires "activation" conditions to react properly. There are various additives that accelerate the hardening of cements, among which calcium chloride shows the best performance. The effects of calcium chloride are particularly important during the first days of hydration. However, their use is strongly regulated because of the corrosive effect of chlorine on steels of reinforced concrete. The objectives of the thesis are to study the mechanisms of action of calcium chloride on cement-slag binders during the first days of hydration. A panel of experimental techniques has been used to specifically identify the action of chlorides on slag and cement. Coupled results from XRD-NMR SEM experiments show that calcium chloride causes an accelerated precipitation of portlandite and ettringite, resulting from the increase in the reaction rate of clinker. The start of the slag reaction takes place after about 12 hours, and is not impacted by the calcium chloride. On the other hand, the reaction rate of the slag increases in the presence of the accelerator. The rapid, significant and exclusive formation of Friedel salts in the presence of chloride is observed, replacing sulphated and / or carbonated AFm. Increasing the reaction rate of the anhydrous phases results in the precipitation of additional C-S-H. This formation of Friedel salts and C-S-H causes a faster filling of the porosity and the increase of the mechanical performances
