Texas Green Technologies LLC
Richmond, Texas, United States

Texas Green Technologies is a USA-based company which delivers an integrated solution for the capture and use of industrial heat. With an extensive and unique knowledge of the ORC (Organic Rankine Cycle)system applications, together with the expertise to convert most thermal sources into electrical power, we design, manufacture and install power plants to increase our customer’s power production.

The Organic Rankine Cycle

The Rankine cycle is named after its inventor, the scottish physicist William Rankine (1820-1872), one of the fathers of thermodynamics.

The concept behind the Organic Rankine Cycle is simple, but is better explained through a schematic.

A heat source - such as the flames of aboiler, hot flue gases or any other comparable heat source - heats, by way of a heat exchanger (2) a special working fluid that is the real secret behind LT ORC technology. This fluid, which is 100% biodegradable and non-toxic, starts boiling and expands dramatically even when exposed to a temperature lower than that of water and becomes a dry, highly pressurized gas which moves a turbine (3), producing mechanical power (Wturbine ) that, in our plants, is converted by a direct drive alternator into electric power, which is used on site or sent to the power grid.

On exiting the turbine the working fluid goes through to a condensating heat exchanger (4) where it gives off its excess heat, condenses into a liquid form again and goes to a storage tank (1), ready to be pumped back to the secondary exchanger, thus closing the cycle.

The excess low-temperature heat given off in the condensating exchanger (Qout) can used for ambiental heating purposes, or to preheat fuel, or again to reduce the water content of biomass prior to burning, thus increasing its heating value.

Texas Green Technologies does not just sell you a plant : it offers you a full-fledged engineering consultancy service dedicated to inegrating our plant with your existing technology.

The first step is usually an up-to-date energy balance checkup : this is the moment in which current power consumption and production needs are evaluated and future production needs estimated.

The next step involves a verification of fuel specifications - by analyzing both the raw biomass and its combustion products including flue gases and ashes.

Then, all applicable technology integration paths between old and new plants are evaluated, finding the most advantageous path both from a logistic and economical standpoint for the newly generated electric and thermal enegy flows.

Once the former data has been acquired, it is time for thge final plant sizing, which includes locating the best area where to place the skid-mounted energy module, the fuel storage areas, and where to place the accessory plant (such as cooling towers).

Operative projects are then submitted to the client's attention for final approval.

Once the project has been approved and the order received, the plant is assembled and installed entirely by the personnel of Texas Green Technologies and its consociates under the supervision of the engineers who designed the plant itself.

Once the plant has been tested, started up and accepted, collaboration with Texas Green Technologies may continue; we can supply maintenance contracts and plans tu suit all your needs, from ordinary on-call maintenance to lifetime full-risk.

Operational training and the possibility of continuous remote plant monitoring complete the package that Texas Green Technologies offers its clients.
