ANALYSIS AND CONTROL OF EMISSIONS FROM PULP AND PAPER MILL
Dr. Pradeep Kumar* and Nikita Agarwal
ABSTRACT
Pulp & Paper industry is considered as one of the most polluting sector in the world. They are recognized as a source of green house gas emissions in the paper manufacturing sector since they produce CO2, CH4 and N2O during the production process. The major air emissions of the industry come from sulfite mills as recovery furnaces and burners, sulfur oxides (SOx), from Kraft operation as reduced sulfur gases and odor problems, from wood-chips digestion, spent evaporation and bleaching as volatile organic carbons (VOCs), and from combustion process as nitrogen oxides (NOx) and SOx. It would be interesting to analyze and quantify these green house gas emissions from Pulp & Paper mill. The proposed study is an attempt in this direction. The estimation of green house gases from different Pulp & Paper mill of region situated near west of Uttar Pradesh such as Rama paper mill, Kiratpur, Bijnor, Mohit paper mill, Nagina, Bijnor etc has been done using the IPCC 2006 guidelines by calculative methodology. For each mill, daily quantity of fuel burned has been collected for fifteen days using either digitally available meters representing the quantity of fuel burned or by theoretical values suggested by the mill workers. Also, the data has been calculated using formula suggested by IPCC 2006 guidelines and a comparison has been done between observed values and calculated result. Results reveal that significant quantities of GHG emissions are produced using different qualities of fuel such as Charcoal, Tel Rahit Bhussi, Petroleum coke etc. It has also been observed that the emissions coming from petroleum coke is in lesser amount as compared to other fuels. Also the profiles of observed and calculated GHG emissions could not match well. It is suggested that extensive attempts should be made for correct monitoring of GHGEs from pulp & paper mills. Further, it is strongly suggested that continuous monitoring of fuel should be taken care with replacement of Bhussi and coke with pet coke and also quantity of emissions should be monitored before and after each unit of paper production to have better quantification of GHG emissions. Also I have taken a graphical representation of all the fuel in terms of GHG emissions they are emitting respectively.
