Oil & Gas

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

• Gas compressor stations
• Associated Petroleum Gas (APG)
• Process hot streams

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.

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).

PROCESS HOT 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.
