Blythewood, SC, United States, 2013/03/28 - Production at Tiszai Vegyi Kombinat, the largest petrochemical complex in Hungary, relies on a constant supply of water from the River Tisza - SpiraxSarco.com.
The raw river water requires a three-fold purification process before use. Initially, the water is mechanically filtered, it is then pumped into four 4,000m² settling pools for further clarification through the removal of suspended particles, before undergoing a final process of chemical treatment.
In Tiszaújváros, Hungary, where the plant is situated, average winter temperatures remain below 0°C, threatening the water supply if the settling ponds freeze in the sub-zero conditions.
Spirax Sarco (spiraxsarco.com) was asked to design an efficient and cost-effective solution to this challenging problem.
The objective was to take 1,700m³/hr of filtered river water and to raise its temperature by 4-6°C. The solution engineered by Spirax Sarco was to inject 12 bar(g) saturated steam, sourced from a pumping house 300 metres away, directly into the supply pipe, using steam injectors. The steam supply was controlled by an electronically actuated Spirax Sarco control valve.
The solution exceeded the customer’s expectations; noise level and vibrations were minimal, ensuring that the water settling process was not disrupted, and just a quiet buzz could be heard from the injectors.
Spirax Sarco successfully engineered a solution that will ensure a continuous supply of water to the plant, even during the coldest winter months.
