A model description of the adsorption of surfactant-rich stickies onto hydrophobic and hydrophilic mineral surfaces
“Stickies” are tacky species, present in recycled paper and coated broke, derived from coating formulations, adhesives etc. They impact negatively on paper quality and cause web runnability problems by deposit build-up. To sustain recycling, stickies are controlled by adsorbing them onto minerals added to the recycled stock. We report isotherms for a fatty acid ester defoamer and an acrylic aci...

متن کاملAdsorption of Pitch and Stickies on Magnesium Aluminum Hydroxides Treated at Different Temperatures
Magnesium aluminum hydroxides (MAH) of nitrate and carbonate forms were prepared by co-precipitation, dried at different temperatures, and employed as an adsorbent for pitch and stickies in papermaking. Results indicated that MAH that had been heat-treated had higher adsorption capacity to model pitch and stickies at neutral pH. Low-temperature-dried magnesium aluminum hydroxides of nitrate for...
متن کاملSurface Adsorption and Pore-level Properties of Mineral and Related Systems of Relevance to the Recycling of Paper
By Christopher Mark Gribble Surface adsorption and pore-level properties of mineral and related systems of relevance to the recycling of paper. There is a significant problem for the paper recycling industry known as "stickies". "Stickies" are tacky species, present in recycled paper and coated broke, derived from coating fommlations, adhesives, etc. They impact negatively on paper quality and ...
متن کاملAn Experimental Examination of Adsorption Phenomenon in Foamassisted Water Alternative Gas: The Effect of Injection Rate
The main factor affecting the economics of foam-assisted water alternative gas (FAWAG) process is the loss of foaming agent by adsorption onto reservoir rocks. In this study, the effects of phases, surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density were investigated by special adsorption experiments. Moreover, a series of FAWAG tests were performed to ex...
