  2. Pressure exchanger - Wikipedia

    en.wikipedia.org/wiki/Pressure_exchanger

    A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure fluid to such a process is to transfer the waste pressure to a low pressure stream using a pressure ...

  3. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  4. Shell-and-tube heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Shell-and-tube_heat_exchanger

    In shell-and-tube heat exchangers there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurise the low pressure (LP) side of the heat exchanger. [8] The usual configuration of exchangers is for the HP fluid to be in the tubes and for LP water, cooling or heating media to be on the shell side.

  5. Plate heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Plate_heat_exchanger

    Schematic conceptual diagram of a plate and frame heat exchanger. An individual plate for a heat exchanger. The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids.

  6. Heat recovery steam generator - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_steam_generator

    Based on pressure levels, HRSGs can be categorized into single pressure and multi pressure. Single pressure HRSGs have only one steam drum and steam is generated at single pressure level whereas multi pressure HRSGs employ two (double pressure) or three (triple pressure) steam drums. As such triple pressure HRSGs consist of three sections: an ...

  7. Heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Heat_exchanger

    Microchannel heat exchangers are characterized by high heat transfer ratio, low refrigerant charges, compact size, and lower airside pressure drops compared to finned tube heat exchangers. [ citation needed ] Microchannel heat exchangers are widely used in automotive industry as the car radiators, and as condenser, evaporator, and cooling ...

  8. Countercurrent exchange - Wikipedia

    en.wikipedia.org/wiki/Countercurrent_exchange

    A comparison between the operations and effects of a cocurrent and a countercurrent flow exchange system is depicted by the upper and lower diagrams respectively. In both it is assumed (and indicated) that red has a higher value (e.g. of temperature) than blue and that the property being transported in the channels therefore flows from red to blue.

  9. Relief valve - Wikipedia

    en.wikipedia.org/wiki/Relief_valve

    A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.
