SMU Geothermal Conference

The Steam Machine made its world debut at the sixth annual Geothermal Energy Utilization Conference held March 12-14, 2013 on the SMU campus in Dallas, Texas. Langson’s low cost, scalable clean energy production units are significant to the global energy landscape because traditional turbines have substantial problems with saturated steam, but the Steam Machine seamlessly converts it to power.

On Wednesday, March 13, energy tech inventor and LEI founder Richard Langson presented, “Water and Steam Applications of the Langson Helical Screw Energy Converter,” a paper written by his colleague Dr. Ron DiPippo, author of four major books including, Geothermal Power Plants: Principles, Applications and Case Studies.

The Steam Machine is the second product LEI has introduced from its steam and gas turbo-expanders line. By replacing pressure reduction valves (PRVs) with the Steam Machine, significant power is produced that would otherwise be wasted. Larger LEI units can power 1,000 to 5,000 homes per Steam Machine. Langson Energy’s technology is integrated with proven components that have a history of reliable, robust, low-maintenance performance. Langson has solved the challenges of expensive steam turbine solutions for generating power. Traditional turbines have been the accepted method for generating power from steam pressure for many years. However, high capital costs and difficulty in handling wet steam have proven to be significant hurdles to running saturated, contaminated steam, two-phase fluids and geothermal brine. The Steam Machine has significantly lower capital costs than all other steam turbines. The LEI Gas Letdown Generator (GLG), developed earlier, won the bronze Edison Award, for “Best New Green Technology.” The GLG converts natural gas letdown pressure to power like the Steam Machine converts various steam types to power. In addition, the product line has been approved by the Department of Defense for use on military bases.

March 2013 – SMU Conference, Dallas

Come hear Mr. Langson present at the SMU Geothermal Energy conference and see a demonstration of our Steam Machine. It’s happening in Dallas, Texas, March 12-14, on the SMU Campus. Mr. Langson will present on March 13th, at 11:10 am. Meet Mr. Langson, talk with our sales team and learn more about what we have to offer in solving your energy requirements.

 

What is the Gas Letdown Generator?

The Gas Letdown GeneratorTM is an efficient, power generating system that makes electricity from waste pressure. It is capable of directly utilizing and exploiting the energy in waste pressure from virtually any source without expensive, efficiency-reducing heat exchangers or organic mediums to transfer energy.

Power production efficiencies approximate those produced by turbines (isentropic efficiencies exceeding 60%) without the narrow operating parameters required by those devices (little fluctuations in pressures and flows). The Gas Letdown GeneratorTM is a positive displacement device and is unaffected by variations in pressures and flows.

Capable of directly utilizing the pressure in natural gas, wet steam, dry steam, geothermal fluids and many other waste streams, the Gas Letdown GeneratorTM provides significant economic and performance advantages over traditional and non-traditional waste energy capture devices.

What can be used to make power?

The Gas Letdown GeneratorTM is unique in that it will directly accept many renewable or waste streams or “fuel” sources that must be “pre-processed” by other power generation equipment. For example, steam turbines require 100% dry steam to generate power. The Gas Letdown GeneratorTM has patented internal coatings to allow it to directly accept and process natural gas, dry steam, wet steam, two-phase and geothermal fluids and many other sources of pressure to make power. Examples of renewable and wasted energy sources include:

  • Natural gas pressure reduction stations, city gates
  • Oil and Gas Geo-pressure
  • Petrochemical and Industrial Waste Streams, steam, gases
  • Steam
