The chemical treatment of a plant cooling water system is typically provided through a vendor who supplies both chemicals and service. The most common type of system in industrial plants is an open evaporative, recirculating cooling water system (with a cooling tower performing the heat rejection) but closed loop systems and once through systems also require treatment. The chemicals employed are generally proprietary and are specifically engineered to provide control of :
The cost for chemical treatment and service is small compared to the cost of the equipment in a cooling system, on the order of a few percent. However, if plugging of a heat exchanger with mineral scale occurs, or a heat exchanger fails by pitting due to corrosion, the entire annual cost for the chemical treatment and service can be exceeded by a single incident in terms of maintenance, downtime, and/or increased power costs. Poor chemical control can have a very pronounced effect on the life of a cooling tower and can dramatically affect its performance.
A Becht SME can perform an independent review or audit of the cooling water treatment program to verify or ascertain the following:

Allen Feltzin has over 30 years of experience in process engineering, maintenance, operations, and construction in large scale industrial plants based on his long career with BOC Gases, Murray Hill, New Jersey. He developed world class, state of the art cooling systems which were installed at over 80 sites in North America. He was responsible for every aspect associated with cooling towers: design, specification, erection, inspection, testing, retrofits, upgrades, and demolition.
Al developed and presented training courses on cooling water treatment and cooling system equipment, both in North America and globally. He conducted a comprehensive audit achieving cost reductions and optimizations on a 360,000 gpm seawater cooled system at a 360 MW combined cycle power plant.
As an Advisor with Becht, Al has worked with a European refinery to control calcium phosphate deposition and Legionella. He provided consultation to a US Gulf Coast Refinery on cooling tower life cycle optimization: repair vs. replace, review of inspection reports, thermal performance assessment, oversight of contractors, and asbestos abatement. He has built strong professional organizational affiliations, authored numerous technical papers and made presentations to various industry groups including the Cooling Technology Institute, American Chemical Society, National Association of Corrosion Engineers, Compressed Gas Association, and American Institute of Chemical Engineers.
Mr. Feltzin has the following professional affiliations: Cooling Technology Institute, American Chemical Society, National Association of Corrosion Engineers, Compressed Gas Associations, and American Institute of Chemical Engineers.
Mr. Feltzin holds a Bachelor of Science degree in Chemistry from the University of Delaware.
