Leaf (Pelargonium graveolens) — citronellol- and geraniol-rich alcohol oil
Mechotech designs and manufactures turnkey leaf oils distillation plants for Geranium (Pelargonium graveolens), a straightforward leaf-based steam distillation whose oil chemistry is genuinely distinct from the sesquiterpene-dominant profiles of root and heartwood oils: geranium oil's character comes from an alcohol-rich fraction — citronellol and geraniol are its well-documented dominant constituents — giving it the bright, rose-like top and mid notes valued across fragrance and cosmetic formulation. As a geranium oil extraction plant manufacturer, we supply the complete machinery — leaf handling, steam distillation, condensation, and oil-water separation — to process fresh or wilted geranium leaves into a consistent essential oil for the perfumery, cosmetic, and flavour industries.
Mechotech's Geranium plant is engineered around the straightforward, well-established leaf-distillation process for Pelargonium graveolens: unlike vetiver's slow root distillation or sandalwood's long heartwood cycle, geranium leaf releases its oil readily under moderate steam distillation, making cycle times comparable to other common leaf oils. What distinguishes geranium within Mechotech's essential-oil range is its chemistry rather than its process — the oil is dominated by monoterpene alcohols (citronellol and geraniol being the well-documented major constituents), a genuinely different profile from the sesquiterpene-heavy oils of vetiver, patchouli, and sandalwood, giving geranium its characteristic bright, rosy note rather than a woody or earthy base character. Built in SS 316L with integrated condensers, oil-water separation, PLC-based automation, and full documentation, each plant is delivered as a commissioned turnkey system.

Plant Capacities
| Plant Scale | Leaf Throughput | Typical Use |
|---|---|---|
| Pilot | Configured to your feedstock and trial plan | Distillation-parameter validation, oil-yield trials on new leaf lots |
| Semi-Commercial | Configured between pilot and commercial scale | Contract distillation, cosmetic and fragrance-house sample runs |
| Commercial | Configured to raw-material supply and confirmed buyer volume | Export-grade continuous geranium oil production |
Capacity is configured to raw-material supply and confirmed buyer volume; we recommend a pilot plant to validate distillation parameters and confirm the citronellol/geraniol balance for your leaf lot before scaling to commercial throughput.
Manufacturing Process
Leaf Reception & Preparation
Fresh or lightly wilted geranium leaves and tender stems are cleaned of foreign matter and, where required, coarsely chopped to improve steam penetration ahead of charging.
Charging & Distillation
The prepared leaf charge is loaded into the SS 316L still and steam- or hydro-distilled. Geranium leaf releases its alcohol-rich oil readily, so cycle times follow a standard leaf-distillation profile rather than the extended cycles required for root or heartwood feedstock.
Condensation
Vapours pass through an efficient multi-tube condenser with chilled-water circulation, condensing the volatile oil and hydrosol.
Oil–Water Separation
Condensate is separated in a stainless-steel Florentine flask; the essential oil is collected while the hydrosol is drawn off and can be recovered as a co-product valued for its own light rose-geranium aroma.
Polishing & Drying
The crude oil is polish-filtered and dried over anhydrous sodium sulphate (or by vacuum) to remove residual moisture.
Quality Control
Each batch of geranium oil is verified by GC-MS profiling of its citronellol/geraniol alcohol fraction alongside physical parameters (specific gravity, refractive index, optical rotation) before release.

Key Features
Standard Leaf-Distillation Cycle
Geranium's alcohol-rich oil releases readily under moderate steam distillation, so the still is engineered for efficient throughput rather than the extended cycles vetiver or sandalwood require.
SS 316L Construction
All product-contact surfaces are SS 316L for corrosion resistance and product purity, with CIP capability between batches.
Efficient Condensation
High-surface-area multi-tube condensers with chilled-water circulation maximise recovery of geranium's more volatile alcohol-rich fraction.
Alcohol-Chemistry Oil Profile
Standardised around citronellol and geraniol as the dominant constituents, a genuinely distinct chemical profile from the sesquiterpene-heavy oils elsewhere in Mechotech's distillation range.
Hydrosol Recovery
Integrated separation allows recovery of the aromatic hydrosol as a co-product.
Scalable Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
