Reboiler Function

SAF stripper columns remove light hydrocarbons and contaminants that fall outside jet fuel boiling range. The reboiler heats column bottom liquid vaporizing components lighter than jet fuel specification while maintaining heavier fractions in liquid phase. Rising vapor strips volatile materials from descending product ensuring final SAF meets flash point minimum 38°C and distillation profile requirements for aviation safety.

Design Configuration

Thermosiphon or kettle reboiler designs based on column arrangement and heat duty typically 1-8 MMBTU/hr. Shell-and-tube construction with heating medium on shell side and SAF on tube side. ERGIL engineers reboilers for operating pressures 15-100 psig maintaining column conditions that optimize separation without thermal cracking of aviation fuel components.

Heating Methods

Steam reboilers use medium-pressure steam 150-250 psig providing clean controllable heating. Thermal fluid systems circulate hot oil delivering uniform heat without steam infrastructure requirements. Temperature control maintains 180-220°C preventing thermal degradation while ensuring adequate vaporization for effective stripping operation.

Material Selection

Stainless steel construction resists corrosion from aviation fuel and trace contaminants. Tube materials selected for thermal cycling and fouling resistance. Removable bundles enable cleaning maintaining heat transfer efficiency. Design per ASME Section VIII standards with materials meeting aviation fuel production quality requirements.

Applications

Dedicated SAF production facilities refining bio-jet fuel, renewable aviation fuel plants processing sustainable feedstocks, integrated biorefineries producing jet fuel alongside renewable diesel, and facilities upgrading hydroprocessed products to aviation fuel specifications across capacities 2,000-50,000 BPD production rates.

Control Systems

Temperature control modulates heating medium flow maintaining optimal column bottom temperature for effective stripping without product degradation.
