Alumina Refineries

Alumina Refineries

Alumina refinery engineering is one of the strongest and most established domains of Dos Peepal Solutions. Our team brings deep domain expertise across all major refinery process areas—from bauxite handling, crushing, and grinding through desilication, digestion, clarification, precipitation, evaporation, red mud handling, and calcination—including all slurry and liquor systems, supported by strong plant layout development and multidisciplinary engineering capability.

We support projects from concept development and technology selection through basic and detailed engineering, ensuring that refinery designs are practical, operable, safe, and aligned with long-term production and expansion requirements.

Our expertise covers:

Refinery architectural engineering, including site master planning, plot plans, unit layouts

Preparation of Basic Engineering Packages (BEP) for alumina refineries

Material handling systems for raw materials (bauxite, caustic, lime), intermediates, red mud

Mechanical and piping engineering for the entire refinery—process units, utilities, and offsite systems

Recommendation of technically acceptable vendors

Electrical and instrumentation engineering for plant-wide power distribution, control, and automation

Utility engineering, including sizing, design, and integration of all plant utilities

Fire protection engineering applicable across all refinery facilities


With a thorough understanding of refinery operations, interdependencies between process areas, and stringent safety and operability requirements, we deliver engineering that emphasizes constructability, maintainability, reliability, and regulatory compliance.
Our integrated, multidisciplinary approach enables Dos Peepal Solutions to support greenfield and brownfield alumina refinery projects with confidence—delivering coordinated, performance-driven engineering solutions across the complete project lifecycle.
