Jacket

Meaning in chemical engineering, with examples

/ˈdʒækɪt/nounCommon term

In chemical engineering, jacket means: An outer shell around a reactor or vessel through which steam, hot oil or cooling water flows to heat or cool the contents.

In Turkish: ceket, gömlek, ısıtma/soğutma ceketi

How it is used

Typical of batch reactors in pharmaceuticals and fine chemicals. Engineers talk about jacket temperature, jacket inlet and outlet, and half-pipe or dimpled jackets. A 'jacketed reactor' or 'jacketed vessel' has one.

Example sentences

  1. Switch the jacket from steam to cooling water as soon as the reaction starts.

  2. The jacket can't remove heat fast enough in the 10 m³ reactor, so we added an internal coil.

Common collocations

  • jacketed reactor
  • jacket temperature
  • cooling jacket
  • half-pipe jacket
  • reactorA vessel or piece of equipment where a chemical reaction is carried out under controlled temperature, pressure and mixing.
  • heat transfer coefficientA number that shows how easily heat passes from one fluid to another through a wall, measured in W/(m²·K). The higher it is, the smaller the exchanger can be.
  • exothermicDescribes a reaction or process that releases heat to its surroundings, such as combustion, neutralization or most polymerizations.
  • scale upTo take a process that works in the lab or a pilot plant and design it to run at a much larger, commercial size.
  • agitatorA motor-driven shaft with one or more impellers that mixes the contents of a tank or reactor to keep solids suspended, spread heat and help reactions.
