Two stage contact cooler

摘要

An apparatus and process is disclosed for the cooling of a reactor effluent gas stream. The apparatus includes a two stage contact cooling system with a first stage wash zone and second stage wash zone. Each wash zone has a packed bed, or other type of mechanical system for contacting the gas stream with the cooling liquid. The liquid in the first stage will remove heavy components, allowing for a cleaner second stage that can be reduced in size.
