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 optimize 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 US34 500 $.
This case study provides an overview of these efforts at one of the world’s largest nitrogen facilities. During startup, a program to solve a heat exchange problem was implemented, returning all approach values to design.
