The oleochemical industry—spanning fat splitting, fatty acid distillation, methyl ester synthesis, glycerine refining, and fatty alcohol hydrogenation—depends on continuous, precisely managed thermal energy at every stage. From splitting columns operating at 230–270 °C to vacuum distillation reboilers at 180–270 °C and downstream fractionation circuits, thermal oil is the preferred diathermic medium: it delivers uniform heat at low system pressure while eliminating moisture contamination risks inherent to steam heating in sensitive fatty acid streams.

Chemie's focused lineup —  Oleochemicals Eurotherm 320, Oleochemicals Eurotherm 330, and Oleochemicals Eurotherm R‑1000 — covers the full process temperature window with confidence. Eurotherm 330 (−49 ~ 315 °C, 4.04 mm²/s at 40 °C, pour point −68 °C) excels in feed pre‑heating at 80–150 °C, cold‑start circulation, and glycerine purification units, its alkylated aromatic chemistry ensuring immediate fluidity and long service life under continuous cycling. Eurotherm 320 (−30 ~ 320 °C, 9.8 mm²/s at 40 °C) provides stable, low‑viscosity heat to main distillation column reboilers, methyl ester fractionation units, and fatty acid purification loops at 150–300 °C, maintaining sharp thermal gradients that protect product color and acid value. Eurotherm R‑1000, a high heat‑capacity synthetic fluid, is purpose‑matched to fat‑splitting pre‑heater circuits and fatty acid hydrogenation reactors (150–260 °C), where high thermal mass dampens temperature excursions and safeguards catalyst performance throughout extended production runs.

All three fluids operate under low system pressure, reducing mechanical stress across distillation trains, splitting towers, and heat‑integration loops — maximizing uptime and extending maintenance intervals across the oleochemical value chain.
