Below is a complete, CESI-ready Supercritical CO₂ (SC-CO₂) Extraction Process Flow tailored for Elemi resin, Elemi essential oil, Agarwood oil, and mixed perfumery crops under Crown Extraction Solutions Inc. (CESI).
This is formatted in a process-engineering flow with operational parameters, GMP requirements, and scalable design (pilot → commercial).

For Elemi Resin, Elemi Essential Oil, Agarwood Oil & High-Value Perfumery Crops

I. RAW MATERIAL PREPARATION

1. Sourcing

Fresh Elemi resin (Protium copal / Canarium luzonicum)
Dried Agarwood chips (Aquilaria malaccensis / A. crassna)
Other perfumery crops (champaca, ylang-ylang, citrus peels, nutmeg, cinnamon bark)
Certified organic, traceable batches via CESI–CAPI plantation supply chain
Moisture content targets:
- Elemi resin: < 10%
- Agarwood chips: 5–12%
- Leaf/flower crops: 5–8%

2. Pre-processing

Material	Size Reduction	Notes
Elemi resin	granules 5–10 mm	Gentle grinding; avoid friction heat
Agarwood chips	2–5 mm shavings	Uniformity improves solubility
Flowers/leaves	1–3 cm	Shade dried; no sun exposure

3. Pre-Drying & Conditioning

Tray dryer or dehumidifier at 35–45°C
Prevent oxidation (use nitrogen-purged containers)
Store in GMP-compliant bins

II. LOADING & SYSTEM PREPARATION

Seal extractor vessel (5 L pilot / 25–50 L commercial modules)
Load biomass in perforated stainless baskets
Tighten vessel clamps to operational pressure rating (~450 bar)
Purge with CO₂ to remove oxygen and moisture
Start heating jackets to reach extraction temperature

III. EXTRACTION PHASE (SC-CO₂)

A. Operating Parameters

For Elemi Oil (terpenes, limonene, elemicin):

Pressure: 90–150 bar
Temperature: 35–45°C
CO₂ Flow Rate: 8–12 kg/hr per 5 L vessel
Extraction Time: 1.5–2.5 hours

For Elemi Resin Absolute (heavier diterpenes):

Pressure: 250–300 bar
Temperature: 45–55°C
Extraction Time: 2–4 hours
Fractionation: Use dual separators (S1 for volatiles, S2 for resins)

For Agarwood Oil (sesquiterpenes, chromones):

Pressure: 280–350 bar
Temperature: 42–55°C
Time: 4–6 hours
Optional Co-solvent: 2–5% organic ethanol → improves chromone yield

For Flower Oils (champaca, ylang):

Pressure: 90–120 bar
Temperature: 35–40°C
Time: 1–2 hours
Yields: 0.1–1.2% depending on crop

IV. CO₂–SOLUTE SEPARATION STAGE

Separator 1 (S1 – Volatile Light Fraction)

Lower pressure: 70–90 bar
Temperature: 20–25°C
Collect light terpenes (elemi essential oil, monoterpenes)

Separator 2 (S2 – Heavy Fraction)

Pressure: 20–40 bar
Temperature: 5–10°C
Collect oleoresins / agarwood heavy molecular fractions

Separator 3 (Optional – Wax Separator)

Pressure: 5–15 bar
Temp: 0–5°C
Removes unwanted waxes and heavy lipids

V. RECOMPRESSION & CO₂ RECIRCULATION LOOP

Gas recompression pump brings CO₂ back to supercritical region (300+ bar)
Heat exchanger restores SC-CO₂ temperature
CO₂ purification filters remove:
- fine waxes
- dust particles
- residual plant solids
Closed-loop return to extraction vessel

CO₂ recovery rate: 95–98%

VI. FINAL PRODUCT HANDLING

1. Filtration & Polish

0.2–0.45 μm inline filtration
Removes micro-waxes and particulates

2. Fraction Recombination (optional)

Blend S1 + S2 in desired ratio for:
- Premium Elemi Pure Oil
- Elemi absolute
- Agarwood high-chromone oil fractions

3. Vacuum Degassing

Removes trapped CO₂ bubbles
Avoids oxidation

4. Stabilization

Add natural antioxidants (e.g., tocopherols) if required

5. Packaging

Amber glass bottles with nitrogen blanketing
Stainless drums for bulk export
Ensure GMP + ISO 4730 + IFRA compliance

VII. GMP, QA/QC, & LAB ANALYSIS

Standard tests for Elemi & Agarwood oils

Test	Method	Purpose
GC–MS	Chromatographic profiling	Sesquiterpene & resin profile
FTIR	Fingerprint validation	Identity & purity
Specific Gravity	Density measurement	Detect adulteration
Refractive Index	Optical purity	Composition check
Peroxide Value	Oxidation stability	Shelf-life estimation
