Design and Experimental Study of a Milli-channel Vaporizer

open access: yesChemical Engineering Transactions, 2019
The most common way to produce hydrogen at an industrial scale is, by far, the Steam Methane Reforming (SMR) process. The ever-growing interest about hydrogen as the fuel of the future has led to a redesign of the process for smaller production capacity.

Heat Transfer Analysis and Operation Optimization of an Intermediate Fluid Vaporizer

open access: yesEnergies, 2023
An intermediate fluid vaporizer (IFV) is a typical vaporizer of liquefied natural gas (LNG), which is used in a large number of LNG terminals. Since it requires a large supply of seawater during its operation, it generates a lot of energy consumption. In
