de Raad, B.W. (author), van Lieshout, Marit (author), Stougie, L. (author), Ramirez, Andrea (author)Heat pumps are a promising option to decarbonize the industrial sector. However, their performance at a plant-level can be affected by other process changes. In this work, process changes that improve the heat pump's performance have been identified using Process Change Analysis (PCA), where the background pinch point is used as a reference...journal article 2024

Ramirez, Tomas (author)<br/>The maintenance and repairs of transition zones pose significant challenges in the railways industry due to their accelerated degradation rates in comparison to free tracks. These zones, characterized by track property variations, amplify their response when a source travels along the tracks. The resulting amplifications in stress and...master thesis 2023

Blok, K. (author), Ramirez, Andrea (author), Tanzer, Samantha Eleanor (author)Negative emission technologies such as biomass with carbon capture and storage (bioCCS) may become an important instrument to limit global warming. Currently, estimates of CO2 avoidance cost for bioCCS vary widely. Using a case study of a cement plant, this paper illustrates how this variance is partially attributable to the system boundary...journal article 2023

de Raad, B.W. (author), van Lieshout, Marit (author), Stougie, L. (author), Ramirez, Andrea (author)Steam generating heat pumps show great potential for reducing carbon emissions in the industrial sector. However, predicting their performance is challenging as the exergy destruction of e.g., compressors and expansion valves increases with the temperature lift and condenser temperature. With over seventy design improvements mentioned in the...conference paper 2023

Bielefeld, S.E. (author), Cvetkovic, M. (author), Ramirez, Andrea (author)Electrification of processes and utilities is considered a promising option towards the reduction of greenhouse gas emissions from the chemical industry. Therefore, electricity demand is expected to increase steeply. Since the sources of future low-carbon electricity are variable in nature, there is a need for strategies to match availability...journal article 2023

Wiltink, T.J. (author), Yska, Stijn (author), Ramirez, Andrea (author), Pérez-Fortes, Mar (author)Electrochemical reduction of CO2 (CO2ER) is an emerging technology with the potential to limit the use of fossil-based feedstocks in the petrochemical industry by converting CO2 and renewable electricity into useful products such as syngas. Its successful deployment will depend not only on the technology's performance but also on its integration...book chapter 2023

Manalal, J.T. (author), Pérez-Fortes, Mar (author), Ibarra Gonzalez, P. (author), Ramirez, Andrea (author)Due to the heavy dependence on fossil-fuels as raw materials, the defossilization of feedstocks in the petrochemical industry represents a challenge. A large number of possible process routes that use alternative carbon sources (ACS) like CO2, biomass, and waste are being developed for the feedstock replacement. For instance, to produce ethylene...book chapter 2023

Tan, M.D. (author), Ibarra Gonzalez, P. (author), Nikolic, I. (author), Ramirez, Andrea (author)The reliance of the petrochemical industry on fossil-based sources will need to be reduced by the introduction of Alternative carbon sources (ACS). Introducing ACS in a petrochemical cluster will require existing processes to be modified or replaced, potentially affecting other chemical processes within the cluster due to existing material and...book chapter 2023

Subraveti, Sai Gokul (author), Rodríguez Angel, Elda (author), Ramirez, Andrea (author), Roussanaly, Simon (author)Carbon capture and storage (CCS) is an essential technology to mitigate global CO2 emissions from power and industry sectors. Despite the increasing recognition of its importance to achieve the net-zero target, current CCS deployment is far behind targeted ambitions. A key reason is that CCS is often perceived as too expensive. The costs of CCS...journal article 2023

Yáñez, Édgar (author), Meerman, Hans (author), Ramirez, Andrea (author), Castillo, Édgar (author), Faaij, Andre (author)The oil and gas industry is responsible for 6% of total global CO2 emissions, from exploration to downstream petrochemical production and account for another 50% when including the use of its products. Thus, this industry has a significant role in realising the target of net “zero” CO2 emissions by 2070, essential to limit global warming to 1.8 ...journal article 2022
