SO2 emission control
A comprehensive range of services and solutions for evaluating and reducing plant SO2 emissions.
The World Bank and many countries are imposing increasingly tougher environmental restrictions on SO2 emission.
In cement and minerals plants, SO2 emissions are generated from sulfur compounds in the raw materials and, to a lesser extent, from sulfur in the fuel. It is therefore essential for cement producers to ensure that the kiln process is not compromised and that they remain in compliance with emission regulations.
| Services A base-line emissions audit by FLSmidth includes: on-site stack testing process analysis and raw material sampling.
These results are analyzed by process specialists who provide a report that compares current emissions levels against current or future limits, identifies the sources of any emission problems, and recommends practical and economical solutions. |

Solutions FLSmidth offers several systems for reducing SO2 emissions depending on the reduction level:
Our D-SOx Cyclone system is a means of achieving SO2 emissions reduction in the range of 25-30% by taking advantage of the free lime that is created in the calciner.
Our Hydrated Lime Injection (HLI) system can reduce SO2 emission by up to 60% by injecting hydrated lime powder either pneumatically into the preheater or bypass system or via a mechanical feed into the preheater kiln feed.
Additionally, FLSmidth's gas suspension absorber FLS-GSA® is a multi-pollutant control system that provides a high level of SO2 removal of up to 97%, depending on outlet temperature. For higher removal, FLSmidth also provides third-party wet scrubber technology. |
