How Chemi Tech's Desulfurization Defoamer Solves Industrial Foam Challenges?

In a control room of an industrial park in the south, Engineer Li stared intently at the monitoring screen—foam was overflowing from the edges of the desulfurization tower’s observation window, like an untamed white beast devouring operational. System alarms sounded intermittently, level sensors malfunctioned due to foam interference, and workers had to take turns spraying water manually in a futile attempt to suppress the foam.

This wasn’t their first foam crisis. Previous defoamers either lost effectiveness quickly or left residues that clogged nozzles and worsened system burden. Three months ago, the technical team introduced Chemi Tech’s desulfurization defoamer.

It was a pale yellow, translucent liquid with a faint alcohol-like scent. Its micro-nano composite particles rapidly disperse to the foam interface, achieving instant foam collapse and long-term suppression by disrupting film structure. Within ten minutes of the first application, the desulfurization tower’s liquid surface gradually calmed, sensors resumed accurate monitoring, and Engineer Li finally closed his logbook and left the control room with peace of mind.

What surprised the team more was its environmental adaptability. The defoaming performance remained stable even with system pH fluctuations between 4-11, and it showed no stratification or failure under high temperature and high solid content conditions. After four months of continuous operation, the cleaning cycle for the desulfurization tower extended from two weeks to seven weeks, significantly reducing maintenance costs.

Mr. Wang, Chemi Tech’s technical representative, noted: “Many foam issues stem from complex material interactions within the system. Simply pursuing rapid foam breaking may cause side effects. Our product focuses on the root of foam formation, intervening at the early stage of bubble generation to achieve gentler and lasting control.”

Today, foam overflow incidents in the desulfurization system have reduced by over 90%. Engineer Li and his team have shifted their focus to process optimization—while that pale yellow liquid sits quietly beside the dosing tank, an unsung yet indispensable guardian of the production line.
