1D nanotube (HNT) based MMM presents high CO2 permeation due to its long and hollow structure. However, the improvement of selectivity is still challenging. In this study, small PEI molecules with abundant amino groups were introduced into the nanocages of ZIF-8 HNTs to construct facilitated CO2...

A case study of total process energy-integration in a commercial ammonia plant was performed using a modified pinch analysis. Several tools, including Grid Diagram, Composite Curve (CC), Grand Composite Curve (GCC), Balanced Grand Composite Curve (BGCC) and Splitting Grand Composite Curve...
