Executive Summary
A leading international essential oil manufacturer required a fully automated, GMP-compliant Lemongrass Essential Oil Distillation Plant to produce premium-quality Lemongrass Essential Oil with high Citral (Geranial & Neral) content for export to the flavor, fragrance, pharmaceutical, cosmetic, aromatherapy, and personal care industries.
The customer sought a turnkey processing facility capable of maximizing essential oil recovery, preserving volatile aromatic compounds, reducing steam and energy consumption, and delivering consistent export-grade quality with full batch traceability.
MECH O TECH LLP successfully designed, engineered, manufactured, supplied, installed, and commissioned a 20 TPD Lemongrass Essential Oil Distillation Plant incorporating advanced steam distillation, high-efficiency condensation, precision oil-water separation, condensate recovery, automated utility management, and intelligent PLC-SCADA automation.
The facility consistently produces premium Lemongrass Essential Oil with superior citral content, excellent aroma, high purity, and exceptional production efficiency.
Customer Background
The customer manufactures essential oils for flavor & fragrance industries, cosmetic manufacturers, personal care companies, pharmaceutical companies, aromatherapy brands, household product manufacturers, nutraceutical companies, and global essential oil exporters.

Process Description
Raw Material Preparation
Freshly harvested lemongrass is cleaned, inspected, and chopped into uniform lengths to improve steam penetration and maximize oil recovery.
Steam Distillation
Prepared lemongrass is loaded into stainless steel distillation vessels where saturated steam passes uniformly through the biomass.
The optimized process provides:
- High essential oil recovery
- Excellent citral preservation
- Uniform steam distribution
- Reduced processing time
- Consistent oil quality
Condensation
Oil-bearing vapors are condensed using high-efficiency shell-and-tube condensers that rapidly cool the vapor mixture while minimizing volatile oil losses.
Advantages include:
- High condensation efficiency
- Reduced cooling water usage
- Improved energy efficiency
- Stable continuous operation
Oil-Water Separation
The condensate enters precision-engineered Florentine separators where essential oil is separated from aromatic hydrosol.
Recovered products include:
- Premium Lemongrass Essential Oil
- Lemongrass Hydrosol (value-added by-product)
Oil Filtration
The separated oil passes through fine filtration systems to remove suspended impurities while maintaining its natural color, aroma, and chemical composition.
Quality Standardization
Each production batch is analyzed for:
- Citral Content
- Specific Gravity
- Refractive Index
- Optical Rotation
- Moisture
- Purity
- Color
- Organoleptic Properties
Only compliant batches proceed to storage and packaging.
