Synthesis and optimization of NGL separation as a complex energy-integrated distillation sequence

The synthesis of heat-integrated distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures is complex due to the many interconnected design degrees of freedom. This paper explores the basis on which reliable screening can be carried out. To solve this problem, a screening algorithm has been developed using...

Using Real Building Energy Use Data to Explain the Energy Performance Gap of Energy-Efficient Residential Buildings: A Case Study from the Hot Summer and Cold Winter Zone in China

The International Energy Agency (IEA) emphasizes that using real building energy use data (RBEUD) to reflect the actual condition of buildings and inform policy-making is the most effective way to reduce buildings’ carbon emissions. However, based on IEA’s evaluation, regional and national building stock data are limited and lacking. Especially...

Cascade CO₂ electroreduction enables efficient carbonate-free production of ethylene

CO ₂ electroreduction offers a route to net-zero-emission production of C ₂H ₄—the most-produced organic compound. However, the formation of carbonate in this process causes loss of CO ₂ and a severe energy consumption/production penalty. Dividing the CO ₂-to-C ₂H ₄...

Challenges and opportunities for process intensification in Europe from a process systems engineering perspective

Process Intensification (PI) is an effective way to enhance process efficiency and sustainability at affordable costs and efforts, attracting particular interest in the European area, as one of the most important chemical production areas in the world. PI primarily contributes by developing and testing new processing technologies that once...

Energy-Efficient and Robust Cryo-CMOS Smart Temperature Sensor: A Capacitively-Biased Diode-Based Cryo-CMOS Temperature Sensor with Hybrid Voltage-Time Domain Readout

Quantum computers, mainly rely on quantum bits (qubits), which need to be operated at cryogenic temperatures. With the need for systems with thousands or even millions of qubits, the challenges of wiring and scalability become more apparent. To address this, several studies focused on the idea of fully integrated cryogenic controller systems. It...
