Enhancing exchangers across all industry sectors

Globally CALGAVIN® has brought process benefits to a variety of plants reducing capital and operating costs through increased performance efficiency within most, if not all, industries.


China, EOG Condenser

EO Plant

Provided increased heat and mass transfer allowing manufacture of exchanger within column size constraints. Kept tube count to a minimum for 4 units of 7000, 9000, 15300 & 14100 tube bundles.


Thailand, Lean/Rich TEG Exchangers


Enhancement provides 92% increase in tube side coefficient resulting in 30% increase in overall duty. Successfully de-bottlenecked the existing unit.


Russia, Feed Effluent Exchangers

Heavy Naphtha Unit

Furnace capacity limited production. hiTRAN® enhancement adds 4.6MW extra heat recovery. Very short payback.


Mexico, Dry/Wet Crude Exchangers

Offshore Terminal

Increased heat transfer results in a reduction of shells from 20 to 8. Plot space reduced by 76% and capital costs savings over US$2M.

BP Germany

Feed Effluent Exchanger

p-Xylol Unit

Enhancement provides 15% increased throughput from adding 0.8MW more heat recovery. CO2 reduced by 1700 t/y.


Australia, Condensate Heaters

Gas Plant

With an increase in throughput, this brought about film boiling which was mitigated using hiTRAN® and still achieved required outlet temperatures at the increased duty.


UK, Diesel Rundown Coolers

Oil Refinery

hiTRAN® Thermal Systems were used for a new design to operate with 2-3 deg Celsius temperature difference between the ambient air and diesel gas oil terminal temperatures, for both summer and winter conditions,keeping within plot space constraints


UK, Crude Oil Preheat Exchanger

Vacuum Distillation Unit

Retrofit increased wall shear stress from 0.7 to 2.1Pa and increased the overall heat transfer by 262%, enabling 12 Degree Celsius lower average wall temperatures mitigating fouling and increasing run time.


Angola, Wet/Dry Crude Exchangers


500% increase in co-efficient reduces shells from 9 to 2. Weight reduced from 401 tonnes to 130 tonnes. Cost reduced to 65%


USA, Vent Condenser

Polypropylene plant

Significantly exceeded performance expectation. Saved capital cost of exchanger replacement. 13% increased product retention.


Germany, Gas Oil/Crude Cooler

Vacuum Distillation

Unit Process fluid flow viscosity of up to 400cP was enhanced on both the tube side and shell side reducing capital cost of a new design by $128,000 for one unit, with 52% reduction in heat transfer area.


UK, Lean/Rich Glycol Exchanger

Gas dehydration package, Offshore Platform

Enhancement in Duplex material was provided in order to meet a specific duty but keep within plot space constraints for the platform. With a standard design this was not possible, only achievable with tube side enhancement.
