Organic Rankine Cycle (ORC)
An Organic Rankine Cycle is best suited to making electricity from low-grade heat sources, using an organic fluid to match the fluid’s properties with the temperature of the heat source.

Source Temperatures < 350ºF For sources below 350ºF, ORC is the only commercial option available
Technologies such as forward osmosis are neither commercial, nor do they match
performance, price, or availability
Examples of < 350ºF heat sources are geothermal, amine regeneration, “waste”
steam, co-produced fluids, and refinery product streams
Source Temperatures 350ºF – 550ºF In this temperature range, ORC performance matches or exceeds steam Rankine
cycles, as well as being simpler to operate and maintain
Examples of 350ºF – 550ºF heat sources are geothermal, refinery product streams,
and industrial furnace exhaust
Plant Sizes < 5000 kWe In this size range, ORC is simpler to operate and maintain than a sub-atmospheric
steam plant that requires boiler operators, water treatment, chemicals, and non-
condensable gas equipment
Air Cooled Applications Air cooling steam is a large and expensive proposition; cooling water permits are
increasingly difficult to obtain; using ORC in place of steam or to condense steam from
a backpressure steam turbogenerator at ~30 psia is a viable option
Where Does ORC Have a Technology Advantage?

Shaft seals Mechanical losses: ≈ 1–2%
Gearbox Mechanical losses: ≈ 4%
Couplings Inspection and maintenance costs
Lubricated bearings Mechanical losses: ≈ 2%
Oil systems Parasitic power losses: ≈ 2%
Instrumentation Separate vibration probes & proximity sensors are usually required to
monitor turbine and/or gearbox shaft vibration levels
Turbine matching Standardized turbine designs of many ORC systems are a poor match for
many applications
CN300 avoids all these problems
Conventional ORC Drawbacks Include
9–10% Power Losses
