Alfa Laval Packinox heat exchanger Paraffins Olefins Recycled hydrogen Standard combined feed/effluent heat exchanger Alfa Laval Packinox for paraffin dehydrogenation Paraffin dehydrogenation is a process which typically demands low pressure drop, efficient treatment of two-phase fluids and resistance to the hazard of catalyst fines. These three challenges are effectively met by Alfa Laval Packinox heat exchangers. • Alfa Laval Packinox offers very low pressure drop. • Uniform flow and distribution of two-phase fluids within the plate bundle is ensured by patented Alfa Laval Packinox spray bars, while poor entrainment and distribution associated with low pressure drop and heavier hydrocarbons continues to be a problem for shell-&-tube exchangers. Tubulars would need a substantial overdesign to match Alfa Laval Packinox performance. • Furthermore, the space between the plates of Alfa Laval Packinox exchangers in this application is generally about 5 mm, allowing problem-free passage of catalyst fines. 273607_PCT00076EN:251765_packinox_paraffin_dehydro_PPM00115 14/05/07 14:00 Side 1
