Establishing a Comprehensive Stickies Treatment Program by Utilizing the Kemira Organic Deposit Test (KODT) Provides Enhanced Deposit Control Efficiency

摘要

A wide variety of stickie organic contaminants enters the papermakers process with the recycled furnishes. The mostrneffective method to controlling stickie contaminants is to establish an effective comprehensive deposit preventionrnapproach that can address the most common papermaking processes and equipments.rnThere are a wide range of treatment chemistry approaches (i.e. talc, cationic fixative polymers, surface activernpolymers, cationic surfactants and inorganic chelants) that are marketed for controlling stickies deposition. Therndifficulty has been in the product selection process as to which technology provides the greatest probability ofrnsuccess.rnToo often suppliers attempt to market only one or too few product chemistry technology classes. In many cases, thisrnresults in the wrong and/or costly solution attempts. The ideal approach is to offer the complete line of chemicalrntechnology classes and then through a non-prejudiced perspective allow the customers process and contaminantrnrequirements dictate the most cost effective treatment approach.rnThis paper discusses the Kemira Organic Deposit Test (KODT), and its usefulness in the field for the selection ofrnthe most cost effective deposit control technology. This test utilizes the customer's specific furnish type and processrnconditions.rnA case study of SCA South Glens Falls, NY illustrates the significant benefits that derived from utilizing arncomprehensive stickies control program. This study is an example of how the KODT accurately determines thernoptimum wet end treatment chemistry.
