Waste Heat Recovery

Energas are experts in ”Waste Heat Recovery” (WHR) – the process of integrating heat or the re-utilisation of heat energy that would ordinarily be discarded or just released into the atmosphere. Waste heat recovery is a process that enables industrial plants to significantly reduce energy costs and improve sustainability through the emissions of CO2 but still increase energy efficiency.

The methods of WHR include the capture and transference of waste heat from a process with a gas or liquid, back to the system to create an extra energy source. Once WHR has been executed the extra energy source can be utilised as an additional heat source to generate hot water, steam or electrical power.

Investing in waste heat recovery is often not considered due to the initial capital cost which is too expensive when compared to the energy saving gained. However, rising energy costs and incentives to reduce the CO2 footprint are generating more opportunities for WHR solutions.

The sectors offering the best opportunities for WHR are power plants (engines or turbines), glass and cement industries where several technologies are available, but not well-known by industrial players. This is where Energas can step in to assist with determining the feasibility, design, system integration and installation.

Power generation through Waste Heat Recovery for international manufacturer

Load shedding, unreliable power supply and increasing electricity costs, all realities that businesses in South Africa must endure, were some of the key factors in a decision made by an international manufacturer to consider generating their own power using natural gas.

The client believed that Energas Technologies, as a leading supplier of high-end and specialised equipment to the oil and gas industries in sub-Saharan Africa, was the ultimate choice to deliver a complete turnkey natural gas power plant. So why is this?
