Cement Plants
Cement kilns have been targets for traditional cogeneration for decades. As the momentum continues for this process in the cement industry, we can provide an ORC-based “bottoming cycle” – effectively harvesting the heat that remains unused due to traditional cogeneration’s high temperature requirements.
Gas Transmission
Gas gathering and distribution requires compression at regular intervals. In areas where this gas is compressed by a combustion turbine or reciprocating engine, there are inevitably vast quantities of waste heat emitted. We can make use of engine exhaust, cooling jacket waters, and even the process heat from compression, and in some instances provide heat to fire amine plants and dehydrators by sending low-pressure high-temperature gas to the facility instead of to our own recuperator, saving operators even more money and emissions.
Pulp, Paper and Wood Products
Pulp, paper and forest products facilities are already very efficient in recovering heat for their industrial processes. However, purchased energy remains the 3rd largest manufacturing cost in the industry. Our solutions allow mills to economically and efficiently utilize the residual (waste) heat for generating the higher value commodity: electricity. Examples of excellent sources of waste heat include black liquor recovery boilers, kilns, power boilers, venting steam and hot liquid streams.

Refineries
Refining of oil and petrochemicals is typified by large quantities of heat and pressure. Furnaces, crackers, and boilers are excellent sources of waste heat, as are on-site combustion turbines used for power generation. Our systems can help refinery and petrochemical customers by acting as a cooling medium. Wherever customers are spending money to cool their fluid or gas streams, we can instead provide this service, harvesting the heat to produce power and eliminating costs for cooling the various streams.
Steel and Metals Furnaces
Furnaces are excellent sources of waste heat due to their relatively high temperatures. Whether for steel, cast parts, or other metal processes, our solutions offer mills and processing facilities a way to harvest the heat from these furnaces to lower their power bills and reduce their carbon footprint.
Power Plants
Power plants – particularly gas turbine-driven plants – can have exhaust stack temperatures hot enough for secondary (or tertiary if they are already operating in combined cycle mode with a heat recovery steam generator).
