Guidelines for Developing an Efficient Equipment Layout
II JAY SHRI KRISHNA II
In the complex world of industrial plant design, achieving optimal efficiency, safety and productivity hinges on a single, critical element: The Equipment Layout. As a continuation of our exploration into 'Equipment Layout: An Effective Industrial Arrangement,' we now delve deeper into the practical guidelines that transform conceptual designs into operational realities.
Introduction:
A well-structured equipment layout is not merely a spatial arrangement; it's the backbone of a successful industrial facility. It dictates workflow, influences maintenance procedures and significantly impacts the overall safety profile. By meticulously integrating process efficiency, accessibility, maintenance requirements and strict safety compliance, a thoughtfully designed layout minimizes risks, reduces operational costs and lays the groundwork for future scalability.

Key Guidelines for Equipment Layout Development
1. Strategic Placement of Furnaces
- Furnaces should be positioned on the outskirts of the unit in upwind directions.
- Process equipment such as reactors, primary fractionators, and distillation columns should be placed close to furnace outlets for short and simple transfer lines.
Example: In a refinery setup, placing furnaces on the periphery reduces heat buildup in core operational areas and enhances worker safety.
2. Accessibility and Maintenance Considerations
- Provide adequate space for furnace tube clearing and removal, with access for mobile cranes.
- Use common platforms for groups of towers to improve accessibility and safety.
- Arrange manholes in towers to face accessways for easy operation.
- Maintain required safety distances for both operation and maintenance.
Example: In chemical plants, ensuring sufficient space for maintenance personnel to operate safely can prevent costly shutdowns.
3. Compressor and Cooler Placement
- Gas compressors should be located downwind of furnaces to prevent exposure to high temperatures.
- Air fin coolers should be placed above pipe racks, typically on the top layer.
Example: In petrochemical plants, placing coolers at an elevated position enhances heat dissipation and system efficiency.
4. Control Room Safety and Placement
- The control room should be in a safe area and centrally located to minimize lead cable lengths.
- Install emergency eye wash stations and safety showers at strategic locations.
Example: In oil refineries, control rooms are placed in blast-resistant structures to protect personnel in case of explosions.
5. Provision for Future Expansion
- Design the layout with space for future expansion, including additional pipeline capacity in pipe racks.
Example: Many industrial zones allocate additional pipe rack space to avoid costly modifications later.
6. Consideration for Large Equipment and Towers
- Plan for the erection of tall towers and heavy equipment.
- Place heat exchangers perpendicular to pipe racks, ensuring sufficient tube pulling/rod cleaning areas.
- Allow at least one meter plus the length of removable bundles for tube bundle removal.
Example: In power plants, strategically placing large turbines helps in smooth maintenance and replacement procedures.
7. Pump Arrangement
- Arrange pumps in a row under pipe racks.
- Pumps handling hydrocarbons or materials above 230°C should not be placed below air fin coolers.
- Position the motor side of pumps toward the center of the rack.
Example: In LNG plants, proper pump placement prevents overheating and improves reliability.
8. Placement of Tall Columns and Furnaces
- Position tall columns and furnaces close to roads for easy maintenance and construction.
- Avoid placing them in congested areas to minimize operational and safety risks.
Example: In distillation units, placing columns near access roads simplifies crane operations during repairs.
9. Reboilers and Fuel Tankage Placement
- Locate thermosiphon reboilers close to their associated towers, preferably mounted on them, to reduce piping complexity and material costs.
- Fuel tankages, except for day tanks, should not be placed inside process units to mitigate fire hazards.
Example: Refineries follow strict placement rules for fuel storage to minimize fire risks and regulatory violations.
10. Approval and Engineering Process
- The equipment layout should be reviewed by all major disciplines and the client for feedback.
- Address conflicting comments through discussions and modify the layout accordingly before final approval.
- The approved layout serves as a basis for further engineering across multiple disciplines:
- Structures: Foundation and superstructure design.
- General Civil: Pavement drawings and equipment foundations.
- Process: Utility P&ID development.
- Piping: Piping layout design.
- Instrumentation: Cable routing planning.
- Electrical: Area classification, trenching, and cable routing.
- Construction: Erection planning and crane hard stand arrangements.
