Executive Summary
A fragrance manufacturer required a fully integrated, GMP-oriented Rose Essential Oil & Rose Absolute Extraction Plant capable of producing premium Rose Otto (Essential Oil), Rose Absolute, and Rose Hydrosol from fresh rose petals for the luxury fragrance, cosmetic, pharmaceutical, and aromatherapy industries.
The customer required a turnkey facility capable of preserving delicate floral aroma compounds, maximising oil yield, minimising solvent and utility consumption, and consistently producing export-quality products meeting IFRA, ISO, GMP, and international perfumery standards.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned a Rose Processing Plant, integrating advanced steam distillation, solvent extraction, concrete production, absolute recovery, precision solvent recovery, vacuum concentration, aroma preservation systems, and intelligent PLC-SCADA automation.
Customer Background
The customer manufactures premium botanical ingredients for luxury perfume houses, cosmetic manufacturers, personal care brands, pharmaceutical companies, aromatherapy companies, premium skincare manufacturers, flavour & fragrance companies, and global essential oil exporters. Increasing worldwide demand for natural floral ingredients prompted the customer to establish a highly automated manufacturing facility with international-quality process controls.

Process Flow
Process Description
Raw Material Preparation
Fresh rose petals are received immediately after harvesting, gently cleaned, and transferred to processing within a few hours to preserve the highest concentration of volatile aromatic compounds.
Steam Distillation
Fresh petals are loaded into specially designed stainless steel distillation vessels where low-pressure saturated steam gently extracts essential oils.
Advantages include:
- High oil recovery
- Low thermal degradation
- Consistent batch quality
Condensation
Steam carrying volatile aromatic compounds is rapidly condensed using high-efficiency shell-and-tube condensers.
Benefits include:
- High condensation efficiency
- Reduced oil losses
- Stable operating conditions
- Lower cooling water consumption
Oil-Water Separation
Condensate flows into precision Florentine separators where Rose Essential Oil is naturally separated from Rose Hydrosol.
Recovered products:
- Premium Rose Essential Oil
- Premium Rose Hydrosol
Rose Concrete Extraction
For premium fragrance applications, fresh petals undergo food/cosmetic-grade solvent extraction to produce Rose Concrete rich in aromatic waxes and fragrance compounds.
Vacuum Solvent Recovery
Rose Concrete is processed in vacuum systems where solvent is recovered, purified, and recycled for reuse.
Benefits include:
- Designed for efficient operation
- Minimal environmental impact
- Improved process safety
Rose Absolute Recovery
Rose Concrete is refined under controlled low-temperature conditions to produce premium Rose Absolute with outstanding fragrance intensity and purity.
Fine Filtration
Final filtration ensures:
- Crystal-clear appearance
- Removal of suspended particles
- Preservation of delicate fragrance compounds
Quality Standardisation
Finished products are analysed for:
- Geraniol Content
- Citronellol Content
- Nerol Content
- Phenethyl Alcohol
- Specific Gravity
- Refractive Index
- Optical Rotation
- Aroma Profile
- Residual Solvent (Absolute)
- Moisture
- Purity
