Proper treating is accomplished by mixing the hydrocarbon from the reactor effluent and aqueous treating streams such as acid, caustic and water, followed by separation. A unique, engineered static mixer is used to turbulently disperse the fluids within, creating the optimum droplet size distribution for mass transfer and subsequent separation.
The mixed fluids are then separated using liquid-liquid separation technology installed in treating vessels. This allows for the separated and treated hydrocarbon stream to be directed to fractionation. Using the correct static mixers paired with the right liquid-liquid separation technology is essential for the system to operate effectively.
Mist eliminator technologies prevent liquid hydrocarbon and liquid acid that is entrained in the hydrocarbon vapor from entering the compressor. A good mist eliminator is critical for long term refrigerant compressor reliability and performance in an alkylation unit.
