Haldor Topsoe launches new catalyst

Haldor Topsoe has launched its new LEAP5TM catalyst as a solution to help sulfuric acid plant operators stay compliant with emissions standards, without lowering production targets, venturing into costly revamps or tail gas treatment with scrubbers.

The new VK-711 LEAP5 catalyst has been optimised for higher activity at lower temperatures.

“By installing the new catalyst, we have improved conversion to produce more sulfuric acid with no additional consumption of raw materials. The improved profitability should pay back the additional cost of the LEAP5 catalyst in two years. In addition to the financial return on the investment we have also reduced SO2 emissions from the plant,” says a representative from Incitec Pivot Limited’s sulphuric acid plant in Mount Isa, Queensland, Australia.

The new catalyst allows operation from temperatures as low as 370°C and is therefore suitable for operators of single absorption sulfuric acid plants who want to achieve unprecedented conversion levels. Other applications include oleum production and more efficient desulfurisation of flue gases from industry.

The catalyst builds on advanced in-situ studies of the working sulfuric acid catalyst, and the industrial experience gained with the LEAP5TM VK-701 introduced in 2010. The new catalyst is already in industrial operation.
