High performance materials
Sulfuric acid involves highly aggressive operating environments. Alfa Laval has a wide selection of corrosion-resistant plate materials and durable, highly resilient gaskets tailored to fit the most demanding sulfuric acid duties. With vast industry expertise, we help you select the right material to match the sulfuric acid process thereby ensuring reliable operation and uptime.
Profit from waste heat recovery
The substantial quantities of heat released by the large-scale production of sulfuric acid represent revenues to be harnessed. As one of the world’s foremost experts in heat recovery technology, Alfa Laval offers trustworthy technologies and long-standing industry expertise to help you recover valuable energy and put it to commercial use.
The energy recovered with Alfa Laval gasketed and semi-welded heat exchangers can be used to heat boiler feedwater for the pre-heating process, supply adjacent plants with energy, or provide district heating to homes and cities. Whatever you choose, there’s a minimal investment in, and maximum savings from, waste heat recovery that helps increase your bottom line.
The sulphuric acid plant and district heating
After reconstructing the cooling system to include plate heat exchangers in a closed loop cooling circuit, the temperature of the cooling water was raised and can now be used for district heating.
