With the successful application of kinetic hydrate inhibitors (KHIs) on plug prevention, there is a growing trend towards development affordable and environmentally friendly KHIs for solving challenges high cost inadequate biodegradability from their commercial KHIs. Therefore, further evaluation inhibitory effect developing needed under multiphase flow conditions. In this study, high-pressure, fully visible rocking cell were used to simulate transportation both considered. The results revealed that, given conditions PVCap exhibited excellent inhibition performance. Although pectin certain growth rate formation quantity, but it demonstrated strong promoting nucleation opportunities rates. However, sodium alginate, which shares similar characteristics with pectin, exerted significantly promotional effects in terms induction time, rate, water conversion. Furthermore, addition alginate led balls several test runs, resulting complete pipeline blockage. Another noteworthy discovery was relationship between final conversion hydrates, an initial increase followed by decrease, while time exhibits inverse trend, as velocity increased.

This study compares carbon emissions from last-mile fresh food delivery using traditional cold storage plates and a new photovoltaic (PV) direct-drive cooling model. A life cycle analysis shows that while the PV model has higher initial production in six cities, it achieves 97.95–98.78 % reduction total over 20 years compared to The plate contributes highest footprint during use stage, stage. emission benefits could be achieved disposal As design temperature inside box increases -5 °C 0 °C, of decrease by 17.74 %–19.31 %, those 13.21 %–18.79 for different cities. Further increasing 5 results more 17.03 %–18.24 15.22 %–19.71 old indicates even minor adjustments settings can have substantial impact on reducing delivery.
