Here is the text from the AtlasCopco page titled: "Energy Recovery"

High-lighting:

"Isobutane vapor is expanded in a binary cycle process that produces
significant electric power."

"Waste heat is another energy source that can be converted to useful energy
by using expanders in an Organic Rankine Cycle (ORC) system."

Energy Conversion & Cryogenic Applications
----------------------------------------------------------------------------

Energy recovery application 

Expanders can enhance your process performance. 

Virtually any process that uses high-temperature or high-pressure gas may
be a resource for energy recovery. Generator-loaded or compressor-loaded
expanders can be custom engineered to recover the maximum amount of useful
energy available in the process.

Waste heat is another energy source that can be converted to useful energy
by using expanders in an Organic Rankine Cycle (ORC) system.

Potential heat sources include: tail gas from industrial furnaces or
combustion engines, waste vapor from chemical and petrochemical processes,
and solar heat from flat or parabolic reflectors.

Extraction of energy from geothermal resources offers a promising
alternative to fossil fuels.

Expanders have demonstrated excellent results in converting low-grade heat
from geological brine streams into electricity. Isobutane vapor is expanded
in a binary cycle process that produces significant electric power.

For gas pressure let down in natural gas pipeline transmission, substantial
energy can be recovered by using expanders to replace throttle valves.

Thermal energy resources can also exist in the world's oceans. In a
demonstration process, an Atlas Copco turboexpander successfully recovered
energy from sun heated ocean surface water, using ammonia as the working
fluid.

In typical investment calculations regarding energy recovery potentials,
payback is often achieved within 18 to 24 months. Since fuel cost for most
turboexpander operations is zero, the expanders can make a significant
contribution to the profitability of your operation.

Your Atlas Copco representative can proved detailed application information
specific to your process, and help project your investment payback cycle.
