This thesis describes the research carried out to solve the foaming issues in Malaysia
LNG Sdn. Bhd. with its Acid Gas Removal Units. The absorber column hydraulics and design is
found to be not suitable for usage of MDEA solvents which gives a higher absorption capacity.
A thorough study of absorber hydraulics and parametric study on foaming behavior is carried
out. Modification for the hydraulics design is calculated and justified to avoid foaming. The
report consist of four chapters that cover the introduction of the project, literature review of
related topics, project methodology, Project Progresses and finally the conclusion.
The introduction part mainly discussed about the background of the study of foaming
issue in the acid gas removal unit using MDEA solvent. Objectives and scope of the study is also
defined here to specify the area of study.
Chapter 2 of the report describes more on the literature review of Hydraulic Limitations,
Foaming Tendency, Foaming Stability, Column Hydraulics Design Consideration, Foaming
Factor, and Acid Gas Absorber (Tray column) Internal Design.
The methodology and project work will be covered in the Chapter 3 of the report. In this
part, the procedure identification of the study, and tooVsoftware required is discussed. The
methodology consists of work on reviewing design consideration for absorber column, study
properties of MDEA solvents and foaming mechanics. The deliverable from this research is to
propose design of absorber column with detailed calculation and modeling which is robust from
MDEA solvent foaming.
Chapter 4 describes the Results and Discussion. Information from the Excel Modeling is
made known here and communicated through tables and calculation basis.
Finally, the project conclusion is stated in the report together with the references used for
research work on this project.
