O&G

Oil & Gas

Turboden ORC units allow to produce useful power (up to 20 MW per single turbine) by recovering waste heat from the exhaust gas of gas turbines/reciprocating engines or from the hot streams that can be found in the O&G downstream, midstream and upstream sectors. ORC technology finds its natural application in natural gas compression stations, but also in the exploitation of flare gas, hot water from exhausted oil wells, and refinery hot streams.

FIELDS OF APPLICATION OF TURBODEN ORC IN THE O&G INDUSTRY:

  • Gas compressor stations
  • Associated Petroleum Gas (APG)
  • Waste heat streams

GAS COMPRESSOR STATION

Turboden Oil&Gas solution

ORC technology, thanks to the use of specific organic working fluids, permits an efficient exploitation of exhaust gas streams, such as small-to-medium size gas turbines in gas compressor stations. Depending on the characteristics of each specific project, i.e. number of gas turbines available for heat recovery, possible layout constrains, water availability on site etc., the ORC solution is designed to best fit with such characteristics.

  • Fuel-free electricity generation
  • Gas saving in case of mechanical drive or electric compressor
  • CO2 emissions reduction
  • Reliable electricity production, even in remote locations

ASSOCIATED PETROLEUM GAS (APG)

Associated Petroleum Gas (APG) can often be found at Oil & Gas extraction sites. When the chemical composition of APG is poor and therefore its exploitation is problematic with traditional technologies, it is typically burned via torches. In such cases, the flare gas is undoubtedly wasted. ORC is a viable technology that can use the energy content of flare gas to produce electric power. The heat recovery configuration involves a boiler fueled by flare gas that heats up a thermal vector fluid, typically thermal oil. The thermal oil feeds the ORC unit, which then produces electricity and thermal power at low temperature (in case of a CHP unit).

WASTE HEAT STREAMS

Both the upstream and the downstream sectors are characterized by the presence of heat sources at medium-to-low temperature. On the one hand, exhausted extraction wells are often full of hot water. On the other hand, oil refining processes take place at high temperatures and the products (diesel, kerosene, etc.) exit the process at temperatures between 150°C and 250°C and must be cooled down before storage. In both cases, an ORC with the proper working fluid can exploit these low enthalpy sources to produce useful power.
