REJECTED AS TECHNICAL AUTHORITY. Methanol behavior depends on feedstock chemistry and distillation conditions; this passage must not be reused as safety guidance without authoritative correction. Fresh full-page audit: Rejected technical claim retained. Source fidelity does not make the simple methanol-heads-removal implication acceptable guidance.
Methanol discussion within materials and chemical considerations.
The source suggests that methanol is removed during foreshots or heads collection, an oversimplification that is unsafe as general distillation guidance.
