50,000 t/y Group III Used-Oil Re-Refinery – Electrical & Energy Engineering
Project Background

GSC contributed electrical and power-system design perspectives for a complex used-oil re-refining facility with a capacity of 50,000 t/y, intended to produce high-quality Group III base oils. The engineering focus included reliable plant power, industrial distribution and energy-efficiency considerations.

Project Objectives
  • Provide a reliable electrical architecture for continuous refinery operation.
  • Estimate plant electrical demand and define major distribution requirements.
  • Supply process units, pumps, heaters, compressors, utilities and auxiliaries.
  • Integrate energy-efficiency measures into motor and drive selection.
  • Address protection, grounding, harmonics, power quality and monitoring.
Engineering / Delivery Challenges
  • Complex continuous-process industrial loads
  • Need for reliable and maintainable electrical distribution
  • Coordination with process and mechanical systems
  • Energy-efficiency considerations in a high-energy industrial facility
GSC Engineering Approach & Methodology

GSC contributed electrical load and distribution planning perspectives together with power-system architecture and equipment considerations, applying energy-efficiency-by-design principles throughout. The work included managing interfaces with process equipment and plant utilities, supported by project-engineering and technical-review input.

Sustainability / Business Impact

The case demonstrates GSC's approach of connecting engineering decisions with reliability, lifecycle value, operational performance and sustainability. Where quantified results are shown above, they are retained from the underlying project material and should not be altered by the website developer.

Lessons & Transferable Value

For process plants, electrical design must be developed as part of the process architecture. Reliability, hazardous-area safety, motor systems, protection, monitoring and energy efficiency should be resolved together because each affects plant availability and lifecycle cost.
