Challenging Investigations into Structural Design of Lean Oil Unit Used in Refineries

Keywords: Structural design, Lean oil unit, Gas processing, steel modules, refineries.


This work describes a challenging structural investigation that was conducted for Lean Oil Unit (LOU) commonly designed in oil refineries. Little guidelines are available in design codes and industrial specifications for design of this type of structures. The paper also describes Numerical models developed to idealize load transfer between various structural systems. Concrete piles are used to support major structures used in the unit. Spring elements are used to simulate soil interaction. Economical strategies and design recommendations are discussed that can be used by practitioners for design of industrial structures and optimize overall project capital cost. The scope of the paper is only limited to the structural designs aspects. Chemical or mechanical aspects are not within the scope of the paper.
