Heat Recovery and Hexane Trapping: Engineering Design of Shell-and-Tube Heat Exchangers by D.ENERGY

In extraction production, heat recovery and solvent vapor condensation directly shape processing costs. Ineffective condensation leads to excessive cooling water consumption, solvent vapor emissions to ventilation, or overloading of the absorption column.

D.ENERGY engineering bureau designs and manufactures shell-and-tube heat exchangers and condensers for aggressive and explosion-hazardous environments of oil plants.

Engineering standards for D.ENERGY heat exchange equipment:

• Thermo-hydraulic design: diameter, length and number of heat exchange tubes are calculated for actual customer heat carrier parameters (miscella, hexane vapors, cooling water, condensate).

• Reliable tube plate connections: automated tube rolling and welding of tube bundles from stainless and carbon steels ensures complete circuit integrity even under water hammer.

• Convenient cleaning and service: the design of removable distribution chambers allows quick mechanical or chemical cleaning of the tube space during scheduled plant shutdowns.

A complex of properly selected heat exchangers and counter-current air coolers closes the thermal balance of the enterprise, reducing steam consumption of the boiler house by up to 20%.
