Total entropy generation rate minimization configuration of a membrane reactor of methanol synthesis via carbon dioxide hydrogenation

PengLei Li et al.

Summary: This study compares the total entropy generation rate, internal exergy loss, and exergy efficiency of a membrane reactor used for methanol synthesis via carbon dioxide hydrogenation. The results indicate that minimizing the total entropy generation rate is equivalent to minimizing the internal exergy loss and maximizing the exergy efficiency under fixed inlet exergy. To optimize the membrane reactor, the total entropy generation rate is minimized as the objective while maintaining a fixed methanol production rate. The optimal temperature curves of the exterior walls for different boundary conditions are obtained using optimal control theory and nonlinear programming. Other geometric and operating parameters are analyzed to determine their influences on the optimization results. The study finds that optimizing the exterior wall temperature reduces the total entropy generation rate of the membrane reactor. Additionally, two different types of membrane reactors are established, and their minimum total entropy generation rates are reduced compared to the reference membrane reactor. These findings are valuable for the optimal design of energy-efficient membrane reactors.

Summary: This study examines the factors influencing the global clean renewable energy transition (RET) and provides a wider perspective through seven broad lenses. Developed countries lead in RET research and collaboration between rich and poor countries is necessary. Local technology promotion and demand-pull and technology-push policies are crucial for successful RET. While there is unanimous optimism regarding the future prospects of renewable energy in the electricity sector, skepticism remains for other high energy demanding areas.

CFD analysis and scale up of a baffled membrane reactor for hydrogen production by steam methane reforming

Hongbum Choi et al.

Summary: Catalytic membrane reactor (CMR) is an intensified process that combines reaction and separation steps. This study explores the concept of placing baffles inside the CMR, called baffled membrane reactor (BMR). Computational fluid dynamics (CFD) simulations compare the performance of CMR and BMR, revealing that BMR exhibits more complex flow patterns and decreased concentration gradients and temperature variations.
