Industrial turbines replacing pressure valves

Recover energy from Pressure Release Valve (PRV) in mining or industrial facilities using micro turbines

Innovative. Disruptive.

Replacing pressure release valves by turbines

Recover dissipated energy

Prevent costly downtimes

Save tons of CO₂ yearly

Disrupt total cost of ownership

Turbine replacing valves

Typical metrics

75kW

recovered energy

Assuming 15kW per valve on average

150k$

saved per year

Replacing a diesel generator costing an average of $0.33 / kWh.

500t of CO₂

saved per year

Replacing a diesel generator releasing 1 ton od CO₂ per MWh.

Select number of valves:

5 Valves

Industrial turbine

Each pressure release valve dissipates an average 15kW of constant energy. A micro turbine can recover that lost energy at low cost, while reducing downtimes.

Typical pressure limit:	50-100 psi
Typical pipe diameter:	4-8 in
At 100 psi pressure flow:	5-50 l/sec
Dissipated energy:	15 kW / Valve

Comparison VS Typical PRV

	Bearstream turbine	Typical PRV
Equipment useful life	10 years	1 year
Number of shutdowns over 10 years Each replacement causes a costly operation shutdown	1	10
Equipment cost over 10 years (15 kW)	1 x $50k †	10 x $5k
Average revenue recovered per micro-turbine per year	$50k	-

† Government energy transition programs of 50-75% subsidy are available.

Significantly lower maintenance intervention

Plug & play. Low cost. Cleantech. Long life.
