Risk based 3-dimensional and multifloor plant layout optimization for liquefied natural gas (LNG) liquefaction process

초록

This paper presents a mathematical formulation for solving a 3-dimensional and multifloor plant layout problem with safety considerations. The presented model is formulated as a mixed integer non-linear programming (MINLP) model and quantifies risk by utilizing Dow's fire and explosion index (Dow's FEI) system. The applicability of the model is demonstrated by an illustrative example regarding layout optimization for the C3MR liquefaction processes.
