Associated and Natural Gas Innovations and Energetics Modernization

One of the most severe problems facing oilfield workers of Kazakhstan and all the CIS countries is associated petroleum gas recovery at new fields. Of course, there is a variety of conventional ways to solve the problem, but they require significant major construction work costs, long terms of project implementation and often do not meet requirements of effectiveness and recoupment of investments.

Associated and Natural Gas Innovations and Energetics Modernization

ENCE GmbH offers an alternative innovation way of problem solving: usage of really new technology – energy unit power plants. This innovation invention opens a fundamentally new economically efficient way of associated petroleum gas recovery and natural gas applications at oil and gas industry. Energy unit heat-and-power plant application is very efficient and effective. Economic efficiency of such plants is hard to be overestimated, because electric power and heat are generated from waste fuel which is traditionally burnt in flares at low-power fields.

Typical advantages of energy unit power plants:

  • Compact module design allows fast installation on any site and operation almost under any weather conditions. The construction does not require any special heavy foundation and thus guarantees easy power plant installation which is critical under severe frost weather conditions
  • Wide range of power plants for different weather conditions
  • Variety of energy unit plant electric powers: from tens of kilowatts up to a few megawatts in one module
  • Allows to generate DC or AC
  • Associated and Natural Gas Innovations and Energetics Modernization
  • Low manufacturing cost of product energy and insignificant operating costs
  • Fuel cell power plants guarantee high efficiency over the range of 60–95%
  • Maintenance is not required during the first five operating years
  • Plant construction has neither rotating nor movable nor high-wear parts
  • There is neither noise nor vibration within all the operation life
  • High level of energy-saving
  • Good ecological compatibility and no harmful emissions
  • Highest reliability, complete faultness and safety
  • Complete computerization, maintenance staff is not required within long operating life
Associated and Natural Gas Innovations and Energetics Modernization

Not long ago such power engineering innovations seemed fantastic. But today energy unit power plants are widely used in industries of many countries. Due to variety of undeniable advantages over conventional power sources and connection layouts independent energy unit heat-and-power plants take increasingly high place in the sphere of clean energy and heat generation. It is important that the plants are installed at the end user’s site. Important reason for their application range extension is continuous increase of gas prices as well as gas and electricity supplier service tariffs.

Associated and Natural Gas Innovations and Energetics Modernization

Energy unit operation principle – energy unit principle of operation is based on generation of electric current and heat from high hydrogen fuel by means of noise-free and flameless electrochemical reaction. Energy units have no combustion procedure which is used in all the rest conventional methods of electric power generation from hydrogen-bearing fuel. Fuel chemical energy is directly converted to electricity, water and heat. Along with natural and associated gas other hydrogen-bearing fuels such as propane, synthesis gas, methanol, diesel fuel and pure hydrogen can be used as powerplant fuels.

Adoption and operation experience over the past thirty years provided the basis for powerful innovation on-site electricity generation plants on the basis of solid-oxide energy units. Up to date such plants generated more than 200 mln kWh of electric power at over 50 plants all over the world.

Heat-and-power plants have high electric and thermal efficiency and can operate on different fuels. They have 35-40% less carbon dioxide emissions in comparison with a conventional thermal power plant or 67% less than mine station. The plant construction is designed for continuous operation for a few years. And at that energy unit plants have very low toxic emissions. One of the advantages is also constant availability of internal electric power source and absence of electric and thermal losses in case if energy is supplied by grid companies. This guarantees high level of energy saving and significant economic advantages in service.
