LAB products

LAB designs and delivers deNOx systems based on Selective Catalytic Reduction (SCR) to reduce nitrogen oxides (NO and NO₂) in flue gases to ultra-low levels. Our own custom-engineered SCR solutions ensure compliance with the strictest environmental regulations, while minimizing reagent consumption and ammonia slip and respecting highest operational reliability.

LAB designs and delivers advanced dry and semi-dry flue gas treatment systems tailored to meet stringent environmental regulations. With our proprietary SecoLAB ®, BicarLAB ® and VapoLAB ® dry flue gas cleaning technologies, we offer flexible and efficient solutions to remove acid gases (SO2, HCl, HF), particulate matter, heavy metals, and dioxins from flue gases.

The SecoLAB ® system uses a direct injection of dry powdered reagent (hydrated lime and activated carbon) into the flue gas duct. The acid gases are neutralized through dry reactions, and the resulting particulates are collected by a high-efficiency bag house filter. To get better removal efficiency and less reagent consumption, a high rate of residue is recirculated into the LAB-Loop ® reactor, where it is mixed again with flue gas and can react with acid pollutants. To improve the reaction the residues are getting into contact with a dedicated flow of water into a humidification screw before being transported back into the LAB-Loop ®.

The VapoLAB ® system uses principially the same equipment and reagent as the SecoLAB ® system. To improve the reaction the residues are getting into contact with a dedicated flow of low-pressure steam injected into a specially designed mixing device, called ActiLAB ® mixer before transporting back into the LAB-Loop. The additional advantage is the perfect mixing of steam with residue which gives a more advanced better reaction with the acid gases and improves efficiency and lime consumption compared to SecoLAB ® system. Because of no need of spraying nozzles, the process is nearly maintenance free.

The BicarLAB ® system uses Na-bicarbonate as reagent. For this reagent flue gas temperature shall be higher (> 160°C) than dry processes with lime. In a first step the injected fine powdered Bicarbonate (pre-grinded reagent or grinded by mills) reacts in the hot flue gas to carbonate, which reacts then with acid pollutants to potassium residue. Principally the same equipment is used as the SecoLAB ® system. To improve the reaction the residues may be recirculated on a dry form. BicarLAB ® ensure a perfect distribution in the flue gas and a long residence time together with the function of bag house filter to achieve a very low reagent consumption. BicarLAB ® is used as a stand alone system or in combination with a DeNOx SCR and completed by a SecoLAB ® system.

Industrial combustion processes can generate high emissions or require very low emissions that need more than a single-step solution. At LAB, we design and deliver combined flue gas treatment systems that integrate multiple technologies into a fully optimized and compact solution, ensuring comprehensive compliance with environmental standards across all regulated pollutants. From dust and acid gases to dioxins, heavy metals, and NOx, our combined systems are engineered to adapt to your specific emission profile, process constraints, and regulatory targets.

High-Efficiency Wet Scrubbing for Acid gases removal. For we don’t talk that we can offer limestone and caustic soda scrubbers. At LAB, we offer advanced wet flue gas treatment systems that provide highly effective removal of acid pollutants and with additional equipment also for dust, aerosols and other pollutants from flue gases downstream combustion processes.

Heat recovery can be achieved either through a direct plates or tubes heat exchanger to transfer the energy directly from the flue gas to the district heating or via an external heat exchanger installed in the water scrubber loop.

Marine Scrubber is one of the most efficient solution to remove the SOx from the Ship Exhaust Gas. Pure sea water or with the add of a reagent, the injection on the top of the scrubber of this circulating liquid allows both gas cooling and an efficient SOx treatment. Our systems operate in various configurations. From Open Loop to Closed Loop or in Hybrid mode, our design ensures flexibility and efficiency across vessel types.
