Removal of air ammonia in a spray tower by dilute sulfuric acid solution

Introduction: Workplace air quality is a very important factor in community health and is measured by measuring and evaluating airborne contaminants. One of these airborne pollutants is ammonia gas. Spray towers are important components of air pollution control. The aim of this study was to investigate the effects of using diluted sulfuric acid solution on the efficiency of ammonia removal in a...

National carbon emissions from the industry process: Production of glass, soda ash, ammonia, calcium carbide and alumina

China has become the world’s largest carbon emitter. Its total carbon emission output from fossil fuel combustion and cement production was approximately 10 Gt CO2 in 2013. However, less is known about carbon emissions from the production of industrial materials, such as mineral products (e.g., lime, soda ash, asphalt roofing), chemical products (e.g., ammonia, nitric acid) and metal products (...

Prediction of Red Mud Bound-Soda Losses in Bayer Process Using Neural Networks

In the Bayer process, the reaction of silica in bauxite with caustic soda causes the loss of great amount of NaOH. In this research, the bound-soda losses in Bayer process solid residue (red mud) are predicted using intelligent techniques. This method, based on the application of regression and artificial neural networks (AAN), has been used to predict red mud bound-soda losses in Iran Alumina C...

Documenting SODA: An Evaluation of the Process Documentation Template

This paper presents an experimental evaluation of the methodology documentation template proposed by the IEEE FIPA Design Process Documentation and Fragmentation working group [1]. Generally aimed at agent-oriented methodologies, the template is here put to the test by documenting the SODA methodology, so as to obtain a partial but significant evaluation of the template’s strengths and weaknesses.
