Simulation study on boil-off gas minimization and recovery strategies at LNG exporting terminals
Liquefied natural gas (LNG) is becoming one of the prominent clean energy sources with its abundance, high calorific value, and low emission and price. Vapors generated from LNG due to heat leak are called boil-off gas (BOG). As world-wide LNG productions are in an increasingly growth, BOG generation and handling problems become more critical subject to more intense global competitions and stri...
متن کاملOptimization of Operating Procedure of LNG Storage Facilities Using Rigorous BOR Model
Abstract: In this study, in order to improve the efficiency and the safety of the LNG storage facilities, the rigorous hybrid dynamical model is proposed. This model is composed of continuous state dynamics which estimate the boil-off rate (BOR) based on understanding of the energy and mass transfer between the stratified cells of LNG storage tanks and discrete state dynamics which describe the...
متن کاملSeismic Performance Evaluation of Boil-Off Gas Compressor in LNG Terminal
Liquefied natural gas (LNG) terminals, one of the lifeline facilities, need to be protected by a proper seismic design against extreme earthquakes. An LNG terminal consists of a series of process facilities that are connected by pipelines of various sizes. Boil-off gas (BOG) compressor is one of the critical process facilities whose failure will cause the functional failure of the LNG terminal....
متن کاملProcess Modelling and Validation of LNG Re-Liquefaction
During transportation, there will be vaporization of LNG producing boil-off gas (BOG) and its re-liquefaction is required considering that large volume of BOG to be vented out. A cryogenic refrigeration cycle is utilized in order to re-liquefy the BOG and returns it to the cargo tank. Kapitza and claude are the usually used LNG re-liquefaction cycles. The developments in the processes adopted f...
متن کاملExergoeconomic Evaluation of an Integrated Nitrogen Rejection Unit with LNG and NGL Co-Production Processes Based on the MFC and Absorbtion Refrigeration Systems
Natural gas is often associated with nitrogen and heavy compounds. The Heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. Therefore, heavy components separation can be a necessity and produce useful products. Virtually, all natural gases are containing nitrogen that would lower the heating value of natural ...
