Diminution of disposal cost and sequestration of carbon dioxide using paper making waste sludge |
| 초록 |
Pulp and paper mill waste sludges generated by primary pulping operation or waste paper making causes an environmental and disposal problem manufacturers of pulp and paper. The pulp and paper sludges digested with several acids for the purpose of dissociation of rigid form. The resulting leached solutions which contains many of calcium ions were treated with carbon dioxide gas for the purpose of mineral carbonation. The remained residuals below 20% composed to almost of organic material contained high calory can be used to energy resources. All the experimental process were proceeded in the media of aqueous solution with addition of amine in the state of open and closed system with carbon dioxide. The high efficiencies carbonation above 99% and high purity of calcium carbonate conversed their feature can be allowed to low cost disposal of paper making waste sludge, carbon dioxide diminution and reusing of calcium carbonate. |
