Coal tar processing demands precision‑controlled heat across a wide temperature spectrum — from initial dehydration at ~120 °C through naphthalene refining, anthracene oil separation, and pitch column heating up to 350 °C. At Chemie, our synthetic fluid lineup — Eurotherm 320, Eurotherm 330, Eurotherm 350, and Eurotherm THT — spans this entire thermal range, ensuring every distillation cut is cleanly separated and every downstream unit runs at peak efficiency.

Eurotherm 330 (‑49 ~ 315 °C), with its exceptional pour point of ‑68 °C, enables reliable cold‑start circulation and low‑temperature light‑oil fractionation without viscosity‑related delays. Eurotherm 320 (‑30 ~ 320 °C) delivers low‑viscosity, uniform heat to phenol oil, cresol, and naphthalene distillation columns operating in the 150–300 °C range. Eurotherm 350 (‑30 ~ 350 °C) sustains stable performance in anthracene oil separation and pitch column heating loops, where continuous cycling demands exceptional thermal endurance. Eurotherm THT (‑10 ~ 350 °C), based on hydrogenated terphenyl chemistry, provides outstanding oxidation resistance for high‑load reboilers and coal tar hydrogenation pre‑heat stages, where long‑term fluid integrity directly protects downstream product quality. Operating at low system pressure, all four fluids reduce equipment stress and maintenance frequency, maximizing uptime and output value across the full coal tar processing chain.
