Organic Rankine Cycle Terminology

Binary Cycle: A geothermal power plant that allows cooler geothermal reservoirs to be used with dry steam or flash steam plants.

 

Carefree® Integrated Power Module (IPM): Core of the Thermapower® and Hydrocurrent™ systems, which consists of a high-speed turbine expander and high-efficiency generator supported by frictionless magnetic bearings and enclosed in a hermetically sealed housing.

 

Closed-Loop System: The process of waste or liquid being treated and returned for reuse (recycled).

 

Condenser: A mechanism that condenses vapor into liquid.

 

Coproduction: Recovering heat from brine and gas produced by oil and gas wells.

 

Energy Recovery: the process of converting non-recyclable waste into accessible heat, electricity or fuel.

 

Evaporator: An apparatus used to turn liquid chemicals into their gas form, which is evaporated or vaporized into a gas.

 

Extra Low Temperature: The 125 XLT optimal heat source temperature is 95.6⁰C (204⁰F).  

 

Geothermal Power: Recovering heat from hot springs and brine produced by geothermal drilling to produce electricity.  A geothermal Organic Rankine Cycle system is often used to convert the heat into power.

 

Heat Exchanger: An instrument that transfers heat from one medium to another.  

 

Hermetically Sealed Unit: The outer packaging used to maintain a seal against the flow of gases, liquids or chemicals.

 

Medium Temperature: The 125 MT optimal heat source temperature is 135⁰C (275⁰F).

 

Organic Rankine Cycle (ORC): Is a heat recovery process that converts thermal energy into mechanical power.

 

Renewable Energy: Energy from an inexhaustible source, such as wind or solar power.

 

Solar Thermal Power: Using energy from the sun to generate thermal energy.

 

Thermodynamic cycle: A sequence of thermodynamic processes that involve transfer of heat and work into and out of the system.

 

Turboexpander: Centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work.

 

Utility interconnection: Connection to public utility electrical grid.

 

Waste Heat Recovery: Converting wasted heat into useable electric power.  

 

Working Fluid-   A fluid, such as R245Fa, that has a particular set of physical properties essential for the operation of a thermodynamic cycle.
