Lextran De-SNOx facility . Coal-fired heating boiler at Beijing International Airport at the capacity equivalent to 20 MWe .

Implemented in a WFGD environment, the unique process advantages of the Lextran process can be realized in the following main solutions:

Lextran’s 3-in-1 SOx, NOx and mercury control: with a generic 85% cost of lime FGD facility and 67% of the running costs, Lextran 3-in-1 process introduces a dramatic saving compared with traditional dedicated facilities which have to be implemented sequentially. Once the investment in an open spray tower has been made, treating NOx and mercury are virtually for free. Bottom line – cost saving of at least 40% in construction, and 50% in operational costs.

Sea Water FGD for coal-fired boilers: SWFGD is a very attractive process to remove SOx from flue gases. It involves no byproducts and no reagents, and is less expensive both in construction and in running. But for coal fired boilers in many countries one has to remove the mercury first. As a de-Hg process prior to the SWFGD, Lextran offers a highly amenable solution that still involves no byproducts and is very effective and reliable.

Retrofit and/or upgrade: many plants have FGD of some sort installed. Whether to increase the SO₂ removal efficiency or to achieve mercury removal without the need to build another dedicated facility, Lextran is ideal to retrofit existing FGDs.

Small boilers: there are many small boilers of the size of 5-50MW capacity. For these boilers it is not practical to consider lime FGD operation because of the prohibitive initial cost, and for the real-estate needed. In both cases, Lextran offers a very cost effective and suitable solution.
