| For
many years Lime has been used to reduce Hydrogen Chloride, Hydrogen Fluoride
along with other pollutants from a variety of process plants. Lime powder
or bicarbonate is blown into a reactor housing and forced over filter elements
normally bags or candles, these are used to trap and hold the lime for the
reactive absorption to take place. The filter systems have been relatively
successful although a number of plants have experienced problems due to
certain constraints required by the lime dosing method. ICE (UK) are introducing a new type of concept for removal of HCl and HF emissions, using a patented module block the system offers some major benefits to both water and lime injection systems. |

| System
Process The system comprises of a special designed reactor housing, the internal structure allows for rows of blocks consisting of Calcium Hydroxide compounds to be located in to the exhaust system. The size of the reactor and the number of blocks depend upon: 1. The emissions level from process and the legal requirement for the particular process 2. The back pressure of the process and fan capabilities 3. Allowances in design for possible future reduction in emissions 4. Stack flow rate 5. Stack Temperatures |

| Process
The off gases containing HCl and HF flows through the Calcium Hydroxide " (Ca(OH)2 " blocks and absorb the HF and HCl. The following reactions take place over the blocks. For removal of HF Ca(OH)2 + 2HF -------> CaF2 + 2H2O For removal of HCl CaCO3 + 2HCl -------> CaCl2 + H2O + CO2 The end product is of a very high purity and can be recycled into raw materials, typically used in the cement, refractory or chemical industries. Typical Applications The dry absorption system can be used for HF and HCl abatement in the following process industries. |

| The AMS System is fully controlled by the use of an ETI- NEO cross duct laser, the monitor is a single component instrument containing a tune-able diode which gives single line spectral absorption at very narrow band pass (0.1nm). The accurate reading provides a signal to automatically operate the motorized dampers, thus controlling the flow through the reactor and limiting the level of emissions to the required permitted level. | ||
