HCl and mercury control with a low-cost DSI solution

Industrial boiler - USA

When incremental mercury control is a concern, a blended sorbent containing both an enhanced hydrated lime and activated carbon can be an economical approach, as it reduces the need for two separate injection systems. Read how Sorbacal® SPAC, a blended product, enabled the removal of over 95% of HCl and more than 80% of mercury at low feed rates.

Dry process SOx removal with five times less sorbent consumption

Brick Factory - Belgium

A brick factory in Belgium faced an emissions problem regarding SO2, SO3 and to a lesser extent HCl and HF. The customer wanted a complete solution that would meet current and future standards. Lhoist set up an on-site test program that ran three months. Read how Sorbacal® SP was by far the best of the sorbents tested, with up to five times less consumption.

Removing micro-pollutants without risk of sorbent combustion

Waste incinerator - Europe

European air regulations not only limit emissions of acid pollutants and dust. They also restrict micro-pollutants. Research by the Lhoist R&D Center led to the development of a mineral non-flammable adsorbent substitute for carbon-based products. It removes micro-pollutants, including dioxins, furans and volatile heavy metals much more safely, and across a far wider range of treatment conditions.

Improvement of SO2 and HCl emission control performance by using a dry process

Biomass power plant - Germany

The customer observed that emission levels of SO2 and HCl were gradually increasing. Furthermore, they realized that at times their flue gas cleaning system would reach its technical limits due to variations in flue gas composition. Discover the results of our proposal regarding the dosing technology, control parameters and operating conditions of the fabric filter by using Sorbacal® SP.
