The link between water treatment and plant profitability is optimal heat transfer efficiency. The buildup of scale and/or biofilm formation can adversely affect operational efficiency in critical cooling systems. Nalco Water provides solutions that optimise these systems while utilizing state-of-the-art automation to track cooling system KPI’s in real-time and automatically adjusts treatment according to system stresses.
Fresh makeup water consumption was reduced by 102,000 m3 per year, equivalent to the total water consumption of 1,300 people in China for one year. The reduced TCO for the air separation plant contributed from Nalco Water treatment is US$ 34,500.
This case study provides an overview of these efforts at one of the world’s largest nitrogen facilities. During startup, a programme to solve a heat exchange problem was implemented, returning all approach values to design.
