SULPHURIC ACID DILUTION – COOLING UNIT

GRAPHITE INDIA Sulphuric Acid Dilution and Cooling Units are mainly used in fertilizer, battery and allied industries for dilution of concentrated acid. Sulphuric Acid Dilution and Cooling Unit consists of a mixer, followed by a heat exchanger. Mixer is used for diluting concentrated sulphuric acid to the desired concentration and the heat exchanger is used for bringing down the temperature of dilute acid to desired temperature (i.e to remove the heat evolved during dilution of concentrated sulphuric acid). Complete unit is mounted on a common carbon steel base frame. The heat exchanger can be either of Polyblock type, Shell and Tube type, or Cascade type.

SALIENT FEATURES

	Ventury type dilution unit with non-return valves. Column type mixers can also provided.

	Polyblock type cooler with flexibility of adding more blocks to increase heat – transfer area.

	Arrangement to give parallel multifeed on service side to avoid temperature – crossing or to maintain desired process side outlet temperature.

	As corrosion severity of dilute sulphuric acid is greater at higher temperature, one sacrificial block and one intermediate chamber is provided, when required.

	Robust and compact design
