Material selection for raw gas pipeline at SBR#2 gas field

Abstract

In engineering design, material selection is the process of choosing the best material for a specific process via a systematic material selection approach. This article described the material selection process for SBR#2 pipeline, which will be installed to flow raw gas from SBR#2 field to the nearest tie-in point. The material selection process starts with design requirement analysis to generate primary function and objectives, including its constraints, determine primary criteria to be evaluated, screen materials candidates based on criteria evaluation, and select the most suitable materials based on very specific requirements. The criteria were evaluated by performing value engineering with the performance criteria matrix tool. Materials selection, in this case, was determined by two main criteria: corrosion resistance and construction ability. Corrosion resistance was evaluated semi-quantitatively by applying NORSOK M-506 2005 spreadsheet, and construction ability were evaluated qualitatively based on field experience. Solid Corrosion Resistance Alloy (CRA)-Stainless Steel 316L pipe is the most suitable for this case.

Optimization of impeller blade number in centrifugal pump for crude oil using Solidworks Flow Simulation

“…A closed impeller has a shroud or walls in front and behind it, providing a sturdy mechanical construction (Cancan et al, 2022;Kan et al, 2022). The oil industry uses closed impellers because they are more efficient in the fluid circulation process they handle (Asfar et al, 2021;Erizon et al, 2022;Putra et al, 2022;Riady et al, 2022). With this closed design, the fluid entering the impeller doesn't come into contact with the casing, and the fluid transferred to the discharge nozzle cannot flow back into the impeller's circulation.…”
