Optimization of green lean six sigma for sustainable manufacturing: NOx concentration design to reduce gas emissions of the chemical industry

Abstract

NOx is the main pollutant of air pollution produced by the activities of industrial companies. Chemical industry companies strive to control the amount of NOX emission gases in order that ensures that the company's operations remain focused on the environment as a form of a sustainable business strategy. The integration of Green Lean Six Sigma (GLSS) is an effective hybrid method to optimize and improve manufacturing process activities to be able to reduce adverse impacts on the environment. The GLSS method combines a statistical approach to optimize process parameters and improve the quality of exhaust gas emissions from the boiler. Thus, the optimal setting for the combustion control system is obtained in the operation and activity of the ammonia and urea industry.
