A novel conceptual design of LNG-sourced natural gas peak-shaving with
gas hydrates as the medium
Abstract
Efficient peak-shaving technology is critical to couple with the
ever-increasing natural gas demand, especially in the regions lack of
natural gas resources. The aim of this paper is to present a novel
natural gas peak-shaving process with gas hydrates as the medium to
address the issue of natural gas supply and demand imbalance, especially
for the LNG-sourced natural gas, in which the cold energy from LGN
gasification can be efficiently utilized. Firstly, the whole process,
including the production, storage, and dissociation of NGH is designed;
afterwards, energy consumption analysis and economic accounting are
conducted; finally, a case study is carried out to show the efficiency
of the technology. The results show that the economic effectiveness can
be improved maximumly by 9.42% compared to the traditional operation
model of LNG receiving terminal, indicating the feasibility of providing
a flexible natural gas peak-shaving process with the gas hydrate as
medium.
