Waste valorization

As there are often waste streams in a plant, the best place to start is a quick scan to identify the opportunities. We typically recommend extending that scan to neighbouring facilities, to see if 'one person's waste is another's treasure' applies.

Subsequently, quick business cases can help prioritize the opportunity list and develop a roadmap, taking into account already planned turnaround schedules. 

Simply put, waste heat valorization is allowing two streams to exchange heat. This could be a flue gas condenser, a heat recovery steam generator (HRSG) or a simple fluid / fluid heat exchanger that helps avoid separate cooling of the hot stream and separate heating of the cold stream.

Apart from selecting and designing the right exchanger and condenser, we also take care of the related piping & control systems. 

If you have streams with remaining calorific value, this can be put to good use. Even if those streams fluctuate in quantity.

To avoid excessive co-firing of natural gas to sustain the flame when loads are low, we can manufacture and install state-of-the-art multi-fuel burners. One such burner can efficiently burn multiple gaseous, liquid and even tar streams without clogging. This solution is compliant with local emission regulations. 

Some waste streams contain molecules that would be valuable to extract. This could be expensive metal particles (e.g., as result of catalyst degeneration), but also hydrogen molecules.

We can support you determining the best technique and then manufacture and procure the right solution, including related piping & control systems.
