Assumptions

- EnCann extracts at ambient temperature

- EnCann does not require changing solvents from extraction to isolation

- EnCann decarboxylation happens inline without solvent removal

- For evaporative solvent recovery, chilling is calculated to condense solvent only, no further chilling

- Heating is performed by resistive heat with a power factor of 1

- Except for chilling, all thermodynamic operations are 100% efficient

- Cannabis oil has the same thermophysical properties as olive oil

- Thermophysical properties are taken at 25°C
