In last two decades, scientists and engineers have developed new reactors for improved yields, safer operations, to reduce waste and higher productivity. Different designs have emerged and are in commercial use based on various concepts/technologies: static mixer, falling film, rotating packed bed, spinning disk and micro-reactors. This article is based on one such novel reactor Downflow Gas Contactor (DGC) for use in a range of gas-liquid and liquid-liquid system. It works on concept of high mass transfer rates generated by fine gas bubbles with interfacial area up to 6,000-m2/m3 and high gas hold-up of 40-50%. The article illustrates the concept, description, mode of operation and industrial applications of DGC.
