ThermaTran engineers have engineered and built twenty-seven (27) HDS / Hydrocracker heater sets.  These units provide process heat for licensed HDS and Hydrocracker designs from U.O.P., Chevron, Unocal, Lummus/-Amoco, Shell and others.

Our thermal designers have experience with every style of heater for these services including vertical cylindrical (both serpentine and helical coils) with or without convection sections, horizontal single and double fired coils and double fired vertical coil designs with or without convection sections.

We maintain a substantial process thermal design computer software library for all options of these types of heaters including:

• All of the above coil and/or firebox geometries.

• Duty analysis of known H₂ / Hydrocarbon streams.

• ThermaTran  H₂ / Hydrocarbon process programs can start with all liquid and blend in H₂ or start with a combined two (2) phase system inlet and model the stream to the outlet of the heater even with the stream becoming all vapor (including superheating) at the outlet.

• ThermaTran programs provide a detailed point by point and/or tube by tube process T, P, H.and mass and linear velocity and tube metal and film average and maximum temperature profiles.
