MECS® ZeCor® Alloy Towers and Pump Tanks
Unsurpassed sulfuric acid process knowledge, combined with our exclusive high-performing ZeCor® alloys, allows MECS® to outperform the industry in the fabrication and operation of corrosion-resistant sulfuric acid plant towers and pump tanks.
Controlling corrosion — in plant towers, pump tanks, and every other piece of sulfuric acid equipment — ranks among the top concerns of every acid plant owner. MECS® ZeCor® Towers and Pump Tanks apply our decades of acid plant experience and technology innovation to solve the problem of corrosion. The superiority of our designs resides in our attention to fine details and our quality fabrication. The superiority of our performance lies in our exclusive ZeCor® alloys. This unique line of specialty metal alloys is proven to provide long-lasting resistance to corrosion and durable service against the unforgiving abuse of sulfuric acid.
Lower Costs and Higher Efficiencies
The corrosion-resistant properties of ZeCor® help our clients enjoy lower maintenance costs and higher plant productivity. MECS® uses ZeCor® material to replace traditional brick lining in the tower, so our systems offer reduced weight, easier installation, and lower foundation costs as well. We also employ processes that allow us to make the tower and pump tank diameters smaller — a big advantage in lowering capital and operational costs.
Our ZeCor® Tower and Pump Tank designs feature MECS® UniFlo® Acid Distributors and Brink® Mist Eliminators to dramatically increase efficiency. In many cases, our Towers and Pump Tanks can be shop-fabricated prior to plant shutdown, and staged on site for insertion of these components as well as tower packing. This ensures minimal plant downtime during installation and a quick turnaround on plant revamps, as well as vastly lower future repair downtime. In fact, thanks to all of their material and fabrication advantages, our ZeCor® alloy vessels deliver many years of safe, trouble-free operation for improved productivity.
High-Performance, Corrosion-Resistant MECS® ZeCor® Alloys
Short for Zero Corrosion, our exclusive line of ZeCor® alloys beat sulfuric acid corrosion in a wide range of concentrations, temperatures, and specific applications. When compared to other, lower-performing material choices, the advantages of ZeCor® are clear.
A Lower-Cost Alloy
ZeCor® alloys are less expensive than other alloys, and comparable in cost with traditional, lower-performing materials, such as cast iron and brick-lined carbon steel. Most importantly, the ZeCor® lifecycle cost is the best available.
MECS uses a proven proprietary welding process with ZeCor® alloy filler. The resulting welds meet ASME Code Section IX standards.
ZeCor® alloys can be easily welded on site by trained plant maintenance staff.
MECS® features ZeCor® alloys in a number of our tower and pump tank components, including acid distributors, packing support grids, vortex breakers, mesh pads, and more.

INFORMATION & IDEAS
Mild hydrocracking is catalytic cracking in the presence of hydrogen and operating at ‘mild’ hydrogen partial pressures. IsoTherming® technology limits the temperature rise across the reactor to minimize undesirable side reactions.
