To bring readers up-to-date on the latest equipment innovations and changes available to papermakers, the following showcase previews some of the technologies on display at the TAPPI ’99 pulp and paper industry exhibit at the Georgia World Congress Center, Atlanta, Ga., March 1-4.
Corresponding booth numbers are included with company names for those attending the exhibit, who may find the Reader Service Card helpful in reducing the amount of collected materials that must be carried around. But the exhibit guide is meant as an aid particularly for those unable to attend the exhibit by allowing them to select and receive information of specific interest.

Boilout additives
Buckman Laboratories designed the Neoteric Boilout Program to help remove organic and inorganic deposits in paper machine systems during neutral pH boilout procedures. Neoteric products are neutral boilout additives that can be used alone or in combination for boiling paper machine systems. The enzyme-based products eliminate the risk associated with caustic or acid burns and do not need to be neutralized before disposal.
