Graphite Sulphuric Acid Dilution Unit

Graphite Sulphuric Acid Dilution Unit


Our clients can avail from us the precision engineered graphite sulfuric acid dilution unit that is design and developed using superior quality raw material and advanced manufacturing technologies. It is simultaneously beneficial for both dilution as well as cooling of acid. The unit is high in performance and can withstand various adverse working conditions

Diluting concentrated sulphuric acid releases, considerable quantities of heat with mixing temperature up to 160°c and above, it is therefore beneficial to dilute and cool acid simultaneously.

This can be accomplished in a single operation with graphite block type dilution cum cooling unit, unit consists of mixing head, which provides separate feed for concentrated sulphuric acid and dilution water. Block type cooling unit provided along with it serves to carry off the heat produced in the course of dilution.

The water and acid are combined only in mixing -chamber, from here dilute acid flows through " process channels of the process blocks, these process channels comes indirectly in contact with the service channels through impermeable graphite and using its high thermal conductivity, as a result desired temperature of dilute acid is obtained at outlet.

Salient Features

  • Skid mounted unit consists of graphite mixing unit, graphite after cooler, graphite inter connecting pipes, teflon lined NRV and bends
  • Simple robust and easy to install tough construction.
  • Multiple passes can be provided on service sides.
  • Graphite has high compressive strength so metal plate apply compressive load on graphite
  • Simple design and easy dismantling as compared to circular blocks
  • Flexibility of adding more blocks to increase heat transfer area.
  • Easy cleaning because of short channels.
  • Short channel lengths increases turbulence as a result avoids frequent deposits or fouling as compared to shell & tube type heat exchanges of same dimensions, cubical block type heat exchanger provides 2 to 5 times more heat transfer.
