Combined heat and power systems in liquefied natural gas (LNG) regasification processes
(2014) Łaciak, Mariusz; Nagy, Stanisław; Włodek, Tomasz
Adaptation of liquefied natural gas (LNG) to the quality requirements for natural gas transportation pipeline system is a high energy intensive process. The energy for this process can be obtained include from waste heat in the industry processes, steam power blocks or sea water in LNG unloading terminal. Another way of obtaining the heat is burning of gas or other fuels. A large temperature difference between the heat sources in each of these cases, and the low temperature of LNG can be used to control of the pumping engine operation, it can provide optimization and reduction of the costs. Liquefied natural gas (LNG) can be used as a source of cold to the increasing power of the cogeneration process. The article examines some practical cogeneration solutions (combined heat and called power - CHP), which can improve the efficiency of the process of regasification of LNG.

Selected thermodynamic aspects of liquefied natural gas (LNG) pipeline flow during unloading process
(2015) Włodek, Tomasz; Łaciak, Mariusz
Liquefied natural gas (LNG) is transported by ships to unloading points on the LNG terminals, where the LNG is transported by above-ground superinsulated pipelines to storage tanks. Storage tanks are located a few hundred meters to several kilometers away from the unloading point. The article shows the changes in the basic thermodynamic parameters of liquefied natural gas during the flow in the pipeline modeled for an exemplary unloading process for different variants using Peng-Robinson equation of state.
