Most gas leaks in South African industrial operations are as a direct result of poor maintenance of gas supply lines. A large number of companies operate for years without undertaking any checks, and are completely unaware that they have numerous leaks that have been caused through degradation, wear and tear over a period of time.
The effects and benefits of conserving gas through optimisation on plants and through leak detection are significant. Less wastage results in less energy consumption during the manufacturing process, which in turn leads to less gas being compressed into cylinders and transported on the roads. This has a trickledown effect, where fewer trucks on the road results in less pollution and wear-and-tear on the vehicles and carriageways. This positive macro-economic effect reflects favourably on the electricity supply grid, as there will ultimately be a more stable supply and less pollution generated from power stations.
- Gas production is costly and must be done efficiently.
- Gas wastage is often not considered as a key contributor to poor energy efficiency.
- Gas leaks must be detected and repaired – and are generally the result of poor maintenance.
