Description
The Eleventh edition of this standard was developed by the HEI Deaerator Section to incorporate the safest available design criteria as well as the highest levels of deaerator performance. The standard contains practical information on the design, construction, and operation of tray type deaerators. It is intended to serve as a guide for individuals who design, specify, purchase, and use tray type deaerators. This standard has been renamed from its original edition, and the content has been revised to reflect the Institute’s position that the tray type deaerator is the superior design type with regard to corrosion resistance and turn down performance. This Standard reflects the collective knowledge and experience of the Deaerator Technical Committee and is reviewed and discussed during regularly scheduled meetings. This process ensures that the Standard will be regularly updated to reflect the latest changes in technology, codes, and member experience. This Standard continues to be influenced by the work of other organizations, such as the American Society of Mechanical Engineers (ASME), American Society for Testing Materials (ASTM), NACE International, the Corrosion Society, and the Technical Association of the Pulp and Paper Industry (TAPPI). Special consideration and credit is given to NACE and TAPPI for their extensive research on deaerator pressure vessel cracking. Particular attention and credit is given to NACE Standard SP0590. Adherence to this Standard is strongly recommended.
