MECS® UniFlo® Acid Distributors for Sulfuric Acid Plants

MECS® UniFlo® Acid Distributors

These unique units deliver continuous acid distribution for optimum absorption efficiency in sulfuric acid plants. Built with our latest lightweight, corrosion-resistant MECS® ZeCor® alloys, UniFlo® Acid Distributors also reduce installation, maintenance and lifecycle costs

With nearly 1000 acid distributors installed in sulfuric acid plants worldwide, MECS® offers proven engineering solutions to meet your organization’s needs. The design of our newest, patented UniFlo® Acid Distributors gives your plant all the advantages of a conventional trough-style distributor, with many added benefits. To start with, UniFlo® Acid Distributors provide continuous and precise distribution of acid throughout the tower packing. This ensures optimum absorption efficiency and less pressure drop, as well as minimum mist generation and maximum service life of downstream equipment.

Fabricated with Corrosion-Resistant ZeCor® Alloys

We offer UniFlo® Acid Distributors in our ZeCor®-Z and ZeCor®-310M alloys, the toughest corrosion-resistant materials on the market, exclusively available from MECS®. These unique engineered alloys exhibit corrosion rates of less than 1 mpy (0.0254 mm/yr) under normal operating conditions in 93% to 99% strong sulfuric acid. In fact, our ZeCor® equipment has a standard life of 20-plus years. As a result, UniFlo® Acid Distributors have significantly lower lifecycle costs than conventional designs in cast iron. What’s more, lightweight ZeCor® makes UniFlo® Acid Distributors easier for plant maintenance personnel to install.

Unique Designs and Processes

To increase cost efficiencies and tower performance, MECS® UniFlo® Acid Distributors reduce the number of trough rows required per tower. Our wider and deeper trough bodies reduce acid velocities to a minimum, decreasing velocity-induced corrosion and plugging, and allowing for smooth acid flow, high absorption efficiency, and lower pressure drop.

A set of uniquely designed and patented gate assemblies in each trough makes setup and flow adjustments quick and easy. These adjustments can be made in minutes without changing out orifice plates. Our open trough design makes visual inspection simple. The result is a distributor with continuous and extremely uniform acid distribution — with the added benefits of faster setup, flow calibration, and field installation.

Expert MECS® engineers can customize UniFlo® Acid Distributors to your sulfuric acid plant specifications. With its lightweight installation, uniform acid distribution, dependability, enhanced safety, easier maintenance, longer life, and lower costs — the advantages of UniFlo® are clear.
