    Friday Workshops

    21st Annual Sulfuric Acid Workshop: Heat Recovery from Acid Plants 1-5PM

    This year’s Sulfuric Acid Workshop will focus on various aspects of engineering, specifications, and operation and maintenance of heat recovery systems from the energy rejected from the acid system. The Workshop will include a review of various systems to recover “low” energy from the acid system. The traditional sulfuric acid process rejects this energy to a cooling water system and is lost. This Workshop will review technical and practical options available.

    The session will include presentations that will be geared towards practicing engineers with various degrees of exposure to the sulfuric acid process, plant operation, and plant maintenance. The Workshop’s objective is to assist engineers in evaluating the operation and the maintenance of their plants. It is necessary for engineers involved in plant operations to fully understand the variety of issues. Following the presentations, there will be a panel discussion providing participants an opportunity to have their questions answered by our distinguished panel of experts in the industry.
