Refinery SDA Unit Project

Get to know more about the project below

Client:

Major Indian Refinery

Software Used:

PDMS, AutoCAD, STAAD Pro, Navisworks, Excel

Sector:

Oil Refining / Residue Upgradation / SDA Processing

Project Overview:

Pan Gulf Technologies was appointed to engineer a Solvent Deasphalting (SDA) Unit to help upgrade atmospheric residue into higher-value distillates. The complex integration into the existing refinery made 3D modeling and stress analysis essential.

Scope of Work:

01. Complete piping layout for solvent and DAO circuits
02. Column and heat exchanger placement and foundation detailing
03. Civil-structural design of equipment platforms and pipe racks
04. Clash detection, MTOs, and fabrication drawings

Key Challenges:

01. High-temperature pipe routing with thermal expansion mitigation
02. Designing for continuous operations and minimal shutdown risk
03. Alignment with existing refinery utility corridors

Engineering Approach:

01. Thermal expansion loops and flexible joint integration
02. Multi-model coordination for process, civil, and structural units
03. Applied ASME/API standards for high-temperature design

Project Outcomes:

01. Flawless tie-ins and zero shutdown conflicts during commissioning
02. Reduced stress points through detailed stress analysis
03. Delivered ahead of schedule due to early-stage clash resolution

Conclusion:

Pan Gulf Technologies ensured a safe and efficient SDA unit integration that supported higher distillate yields. Our specialized refinery engineering experience enabled seamless design-to-construction transitions.
