The use of waste gases from wells and processing of crude oil for cogeneration of electricity and heat

Technical features:

VAPOR CHP gas generator sets and cogeneration units to produce electricity and process heat from waste gas are a solution for companies extracting or processing crude oil, which consume significant quantities of energy or operate at a large distance from power grids. Unlike the gas flares and boilers or pump drives operating at oil fields so far, the VAPOR CHP technology effectively and economically uses waste gases for dispersed generation of electricity for own needs of company or for sale.

The VAPOR CHP technology enables the user to become independent from power grids. The generator meets the demand of the oil field for power (and/or heat) and the possible energy surplus is sold to the power grid. Moreover, a single VAPOR CHP unit with the power of 100 kWel 150 kWth enables annual CO2 emission reduction by ca. 650 Mg by way of replacing waste gas burning in the flare (or gas boiler) with the work of the genset and by ca. 105 Mg for the genset installation at sites not used so far for commercial purposes. The emission of pollutants is also extremely reduced as the waste gas is no longer free burnt but under a controlled process in the combustion chamber of a working generator set.

The technology has wide range of applications e.g. oil and natural gas wells/ fields, refineries, compressor stations and pipelines, storage bases, and oil terminals. In 2011-2012 the technology has been implemented in many PGNiG oil fields (largest Polish oil and gas exploration and distribution company) – as of that time all devices work successfully.

Advantages of the technology:

  • Waste gas use – very low cost of electricity, thermal and cooling energy
    production.
  • Autonomous dispersed production of electricity and process heat
    regardless of local infrastructure.
  • Reduced emissions of CO2 and pollutants (CO, NOX, HC, PM) to the
    atmosphere.
  • Durable design for reliable operation under all working conditions
    (rain, snow, humidity, seaside areas, desert areas, extreme temperatures
    – also in arctic or hot climate).
