Z navdušenjem sporočamo, da je zdaj na voljo drugo glasilo projekta DESOLINATION! V zadnjih šestih mesecih je naša sodelujoča ekipa naredila velik napredek pri doseganju našega cilja, tj. dekarbonizacije postopka razsoljevanja v sušnih regijah.
The global community acknowledges water demand and accessibility as major challenges impacting human well-being. Forward Osmosis (FO) desalination coupled with concentrate solar power might represent a promising solution to combine water production with renewable sources. This work assesses the performance of a liquid-liquid separator (coalescer), an important component of the FO process, when using a polymeric thermo-responsive draw agent (PAGB2000). Experimental characterization of the coalescer is carried out for different regeneration temperatures (from 50 to 80 °C), residence time, draw concentration (from 0.30 to 0.60) and metal meshes. The separation efficiency of the coalescer can be as high as 95% for high residence time and regeneration temperatures (> 70 °C). Eventually, an analytical expression of the coalescer efficiency as function of the main operating parameters is proposed both to support desalination plant design and to enable understanding its applicability beyond its original context.

Together, our project partners, TEMISTH in POLIMI ter LUT sta se z veseljem udeležila prestižnega Turbo Expo (Turbomachinery Technical Conference & Exposition) in London, England, United Kingdom, from June 24-28, 2024.
TEMISTH and POLIMI predstavila svoje najnovejše delo na Predhodna karakterizacija demonstracijskega obrata projekta razsoljevanja: zasnova in obratovalna zmogljivost izven zasnove.
Marco Astolfi, from Politecnico di Milano (our project coordinator) was invited to present the project and participate in discussions to share ideas and gather suggestions from the supercritical CO2 community.
LUT je aktivno sodeloval v več panelnih razpravah, ki so se osredotočale na izkušnje, pridobljene pri preteklih in tekočih eksperimentalnih projektih sCO2.
Konferenca je ponudila dragocene priložnosti za mreženje in izmenjavo spoznanj s kolegi z vsega sveta.
Udeleženci so se lahko udeležili tudi vrste visokokakovostnih znanstvenih predstavitev. Dogodek se je izkazal za vir navdiha, saj je ekipi LUT zagotovil sveže ideje za sedanje in prihodnje projekte.
Letošnji dogodek je bil osredotočen na ključne korake, ki so potrebni za doseganje ničelne prihodnosti na področju pogona in energije. Udeleženci so raziskovali prelomne tehnologije, ki presegajo tradicionalne rešitve s plinskimi turbinami, vključno z napredkom na področju vodika. Program je izpostavil tudi širši ekosistem, ki podpira trajnostne izdelke, kot je zelena energija za nizkoogljična sintetična goriva, ter ključna področja, kot so certificiranje, predpisi in ekonomija obsega. Udeleženci so prispevali k oblikovanju skupnega načrta za bolj inovativno in trajnostno prihodnost.
Carbon dioxide binarFIGy mixtures are increasingly considered as working fluids in transcritical power cycles, due to the capability to perform liquid-phase compression even at high environmental temperatures. However, a robust thermodynamic model is essential for optimal and reliable design conditions. It is widely recognized that fine-tuning the equation of state with experimental vapor-liquid equilibrium data of the mixture significantly enhances its reliability.
In this work, a new apparatus dedicated to vapour-liquid equilibrium measurements of mixtures is presented. The proposed method consists of a constant-volume system, where bubble points are identified from the divergence of slope of the isochoric lines between the two-phase and liquid regions, in the temperature-pressure plane. The temperature and pressure limits of the apparatus are 503 K and 25 MPa. Bubble points of CO2 binary mixtures with hexafluorobenzene (C6F6) and n-pentane (C5H12) have been measured and compared with previous literature data for validation purposes. Then, the CO2 mixture with octafluorocyclobutane (c-C4F8) is experimentally studied, addressing a literature gap in bubble point data.
The data are used to calibrate the thermodynamic model, leading to affordable design conditions of the power cycle compared to the non-optimized thermodynamics scenario, in a concentrated solar power tower plant.

The Gulf Cooperation Council (GCC) member countries encompass the Kingdom of Bahrain, Kingdom of Saudi Arabia, State of Kuwait, State of Qatar, Sultanate of Oman, and United Arab Emirates.
the webinar was designed to offer a comprehensive overview of the Horizon Europe Programme, focusing particularly on the avenues open to GCC nations. It emphasized the collaboration framework under Pillar II “Excellence Science,” highlighting ongoing joint projects and sharing best practices for engagement in the Marie Sklodowska-Curie Actions. Furthermore, the event addressed opportunities within Mission Innovation, a global initiative, and underscored potential pathways within the European Innovation Council.
The primary goal of the webinar was to promote enhanced collaboration among GCC countries within the Horizon Europe framework, especially in sectors of mutual interest. By facilitating knowledge sharing and fostering strategic partnerships, the webinar aimed to bolster research and innovation capacities across the region. This initiative ultimately seeks to empower GCC nations to collectively tackle shared challenges and capitalize on opportunities in science, technology, and innovation.
