Multi-stream heat exchanger Alfa Laval Packinox for multi-stream service Alfa Laval Packinox Multi-Stream Heat Exchangers can serve in a range of applications that require handling of multiple streams in a single unit. The reactor effluent chiller for MTBE units is one such example. In this case study, retrofitting a Alfa Laval Packinox reactor effluent chiller into an MTBE unit enhanced efficiency by further cooling reactor effluent after the chiller drum. The 2.8 MW reactor effluent chiller consists of a welded plate bundle maintained by tie rods. It accommodates four streams: reactor effluent, chiller knock-out drum liquid, chiller knock-out drum vapors, and a propane refrigerant.
