            Capture Technology: Temperature Swing Adsorption as Case Study

Reducing fuel consumption is a major goal in planning a ship's voyage. In addition to reducing the operational costs of the voyage, this planning objective influences the energy efficiency of the voyage. This study presents a method for identifying the operational energy efficiency in planning a voyage route to sailboats. In this regard, in the first part of the study was developed a method for determining the Energy Efficiency Performance Indicator (EEOI) of a voyage route for sailing ships. In the second part of the study, to validate the developed method, were analyzed two voyage routes, with imposed limitations, to identify the optimal voyage route around the world for the Training ship „Mircea”. The Training ship „Mircea” is a training ship for the students of the "Mircea cel Bătrân" Naval Academy. The analysis was performed for two navigation routes, namely from East to West and from West to East, departing/arriving from the port of Constanța. The results of the analysis indicate that the route from West to East is the optimal route for Mircea's voyage around the world from the perspective of the ship's energy efficiency.

Temperature Swing Adsorption

Abstract The special report of the Intergovernmental Panel on Climate Change’s (IPCC) on global warming of 1.5 °C marks a critical point in climate negotiations, which emphasizes the importance to control the CO2 level in the atmosphere. The current technology cluster of CO2 capture is still energy-intensive which results in a substantial increase in costs, thus the efficient conversion among various forms of energy is the major topic of research. Considering that most of the existing research are primarily based on the viewpoint of energy conservation on a specific case study, the results thus could not be efficiently generalized as a condensed mechanism of energy dissipation. In this work, the entropy generation evaluation of a 4-step temperature swing adsorption (TSA) process was presented as a sample. The values and contribution distributions of various entropy generation in the thermodynamic cycle were calculated to evaluate the major energy dissipation. The results on contribution distribution of entropy generation and heat required were compared, the entropy generation distribution contributed by heat transfer decreases from 63.27% to 53.72% with internal heat recovery (IHR) method integrated. Thus the entropy generation saving potential of IHR method could be proved.
