Alcohols (C₁–C₄ alkanols) — properties & control

Group: Methanol, Ethanol, Isopropanol, n-Butanol Type: Polar VOCs (–OH functional)
WARNING — flammable solvent vapours; methanol is notably toxic. Water scrubbing works, but design for ATEX/LEL control and add polishing (carbon or catalytic oxidation).
Flammability
High (low flash points)
Water solubility
High (↓ with carbon number)
Odour
Alcoholic / solvent-like
Common sources
Solvents, fermentation, pharma
Toxicity
moderate (high for MeOH)
Flammability
very high
Chronic risk
generally low
Environmental
biodegradable; O₂ demand
AspectDetail
AbsorptionGood in water for MeOH/EtOH/IPA; n-BuOH moderate. Lower temperature ↑ capture.
ReactivityGenerally not oxidizers; some peroxide formation on long storage (solvents).
MaterialsPP/PE/FRP or stainless; ensure antistatic provisions in rich streams.
ATEX/DesignLEL monitoring, grounding/bonding, explosion-safe fans/instrumentation; demister to prevent solvent carry-over.
