Maintenance And Capacity Improvements in Vis-Breaking (Thermal Cracking)

CHALLENGE

Recover considerable heat energy from cracked residue and use it for preheating.

SOLUTION

Tranter SUPERMAX Shell And Plate Heat Exchangers can undertake preheating duties using the gas oil fraction.

RESULTS

  • Turbulent flow even at low velocities resists fouling better than laminar flow in shell and tube exchangers
  • Also effective as coolers of the light distillate vapor, particularly where column capacity increases have resulted in incomplete condensation.

Tranter Plate Heat Exchanger used in downstream processing.
Tranter SUPERMAX Shell And Plate Heat Exchangers are proven effective as gas oil fraction and light distillate vapor coolers or sulfur dioxide coolers/preheaters.
