Summary: The study investigates the integrated design and optimization of NGL recovery, nitrogen removal, and helium extraction processes, introducing a novel process configuration for co-production of sales gas, NGL, and crude helium. By embedding the helium extraction unit into a single-column nitrogen removal process, the proposed design significantly reduces equipment quantity and eliminates the need for open refrigeration cycles and propane pre-cooling systems in NGL plants. High ethane and helium recovery, efficient nitrogen removal, and high purity crude helium are the outstanding potentials of the novel process.

Summary: The thermal-hydraulic behavior of supercritical water reactors with a parallel channel configuration was examined through a non-linear instability analysis. Different working supercritical fluids, varied heat-flux and flow-rate conditions, and channel inclinations were taken into account. The major findings show that both water and carbon dioxide experienced density wave oscillations at low subcooling numbers, and static instability characteristics were observed for supercritical water. Moreover, the heat flux and inclination angle had an impact on system stability, while parallel channels performed similarly to a single-channel system at equal heat flux. Stable and unstable limit cycles with out-of-phase oscillation characteristics were observed in dynamic stability regions.

Summary: The challenge of reducing the carbon footprint and development costs of chemical processes can be achieved through process intensification (PI). Different PI technologies have been investigated, with rotating packed bed (RPB) technology receiving attention for its potential in intensification. This study presents a complete derivation of dry pressure drop in RPB, incorporating the radial distribution of gas tangential velocity and viscous shear stress. Machine learning techniques are used to derive the inertial resistance coefficient, and an artificial neural network is implemented to relate it to gas flow rate and rotating speed. Results show that using a machine learning algorithm improves the prediction of RPB dry pressure drop compared to relying on empirical models.

Summary: Mini-channel heatsinks are useful in removing high heat fluxes from microelectronic devices. The thermohydraulic characteristics of mini-channel heatsinks depend on the coolant and geometrical configuration of the channel. This study explores the potential of mini-channel heatsinks using different coolants and channel configurations. Increasing the mass flow rate increases the overall heat transfer coefficient and pressure drop. Among the three coolants, supercritical carbon dioxide shows superior performance.

Summary: This study explores the dynamics of magnetohydrodynamic and mix convectional boundary-layer flow of couple stress Casson nanofluid (CSCNF) using a 3D stretchable surface. The addition of active and passive control mechanisms for nanoscales adds a new dimension to the exploration.

Summary: This research focuses on reducing pumping power by investigating efficient channel geometries. The study finds that straight channel precoolers can reduce pumping power by half compared to zigzag channels, but at the cost of a threefold increase in length. The optimal design emphasizes that straight-channel designs can achieve peak efficiency, even though their size may be up to eight times larger than zigzag-channel designs. Meanwhile, precooler designs with zigzag channels strike a balance between cycle efficiency and size under specific conditions.

Summary: The study develops a simplified boiling temperature boundary condition (BTBC) to analyze the performance of printed circuit heat exchanger (PCHE) with semicircular channels. CFD is used to simulate fluid and heat flows in PCHE semicircular channels as a precooler in a combined supercritical CO2 Brayton/Organic Rankine cycle. The results compare the BTBC to heat flux boundary condition (HFBC) and evaluate the heat transfer correlations for SCO2 for both conditions. The study finds that the junctions between different temperature sections have the greatest impact on heat transfer coefficients and the flow from the overheated section to the evaporation section accelerates the increase of these coefficients. The buoyancy effect along the flow direction is also significant and different for the two tested boundary conditions. Additionally, the BTBC has a larger effect on the heat transfer coefficient at different junctions of the precooler compared to the HFBC. The modified Jackson correlation provides a better prediction compared to the Gnielinski correlation.
