Heat Transfer

Very often chemical processes take place in a closely defined and frequently very narrow temperature range.

In industrial plants, salts are used as heat transfer media for heating and cooling as well as for holding at constant temperature.

Durferrit® ASD Heat Transfer Salt

Fields of Application

• Heating of chemical reactors for endothermic processes
  For instance, the commercial syn- theses in packed-bed tubular reac- tors for heterogeneous gas phase reactions.
• Cooling of exothermal reactions for chemical syntheses processes
  The removed heat can be recovered.
• Heat Storage in CPS Solar Power Plants
  for the time-delayed generation of electricity
• Drying of Gases
• Heat Recovery
• General Heat Transfer in Process Engineering

Examples of Use

• Production of phthalic acid (PAA) and maleic acid anhydride (MAA)
• Production of acrylic acid as basic material for acrylates, coloring and super absorber materials
• Production of methyl-methacryla- tes as basic material for flat screens (sheets), acrylic glass and adhesives
• Melamine syntheses
• Hydrogenation and dehydrogenation of hydrocarbons
• Polymerisation reactions
