Casus Belli of the Practical and Theoretical Assessments of the Technological processes of Large-Capacity Production of the Liquefied Natural Gas


Annotation:

Almost always the results of theoretical research do not bring the desired result in practice. This is especially true if there is at least one alternative (competitive) option for applying the process. Production of the liquefied natural gas is a prime example of the need for an understanding of the choice of a single process option that will provide performance indicators with optimal energy efficiency and acceptable safety during the preliminary design stage of a project. One of the research steps may be a comparative analysis of the results of practical (operation of similar facilities) and theoretical (thermodynamic analysis) assessments of the choice of the natural gas liquefaction process at the stage of the feasibility study of the gas field development project (without considering the financial component). 
The task of the presented study was solved based on the indirect comparative analysis of the results of an expert evaluation of operation and theoretical results of a thermodynamic analysis of the liquefaction processes for a project in the territory of the Russian Federation.
The following studies were conducted:

  • choice of LNG technologies;
  • expert evaluation of large-capacity projects for production of the liquefied natural gas in the climatic conditions close to the Arctic;
  • thermodynamic analysis of the energy efficiency of the technological process of large-tonnage production of the liquefied natural gas in the territory of the Russian Federation.
  • The result of the study is the integration of safety and efficiency for making a decision on the choice of the technological process of the natural gas liquefaction at the stage of the Safety Case of the gas field development project.
