Since the industrial revolution in the 18th century, we have halcyon benefits of civilization by the results scientific technical development and industrialization. But density of a pollutant in the atmosphere is increasing for using coal, oil and natural gas in the power plant, car industry and petrochemical industry. Therefore, we are using a packed tower very much, because it is the most suitable method which efficiently removes a pollutant in the atmosphere and maximizes efficiency for large scale plant of petrochemistry etc. Then our company founded JEONJIN ENTECH LTD Attachment The Technology Institution for Chemical & Environmental Process. So that we are studying for environmental pollution matter control with packed tower and chemical process of mass transfer, absorption, desorption and distillation etc for energy-saving and maximization of efficiency
