Background

In 1998, installed three PRDS (Pressure Reducing and Desuperheating Station) units supplied by Mascot Valves. Each unit had a dedicated desuperheater to provide saturated steam for the centrifugals and the boiling house. The boiling house used exhausted steam from the powerhouse and mill house turbines, supplemented with makeup live steam.

The Challenge

Over time, the plant started facing issues related to sugar caramelization. After a detailed investigation, it was found that the steam being used in the evaporators and juice heaters was not being properly desuperheated. This resulted in uneven heating, hot and cold patches on the heating surfaces, negatively affecting the sugar processing quality. At first, to find the solution, the plant personnel assumed that slightly higher steam temperatures might work, not realizing it was causing long-term issues.

The Solution

Mascot Valves then analysed the issue to find its root cause and proposed a practical solution and that was collecting exhaust steam from all prime movers at a central point and desuperheating it uniformly before distribution. This would ensure consistent steam quality across all heating surfaces.

The Outcome

Once the centralized desuperheating system was in place, the issue of caramelization was completely resolved. The steam quality improved, leading to more stable processing conditions. Additionally, the plant observed a noticeable reduction in steam consumption, resulting in operational savings.

The evolution of Mascot, powered by its people, providing continued success to our customers.
