Energy & Emissions Treatment

Singleton Birch provides a range of product grades suited to the specific needs of municipalities, manufacturers, and plant operators to effectively treat emissions and flue gas. These solutions are also highly valued for other environmental applications, such as the treatment of wastewater, sludge, and biosolids. 

Ultralime® Hydrated Lime (calcium hydroxide) and Microlime® Quicklime (calcium oxide) can be effectively employed at different points in the process. Calcium-based reagents are effective at removing acid gases, including:

  • SO2 – Sulfur dioxide
  • H2SO4/SO3 – Sulfuric acid/Sulfur trioxide
  • HCl – Hydrogen chloride
  • HF – Hydrogen fluoride

Ultralime® HS is hydrated lime specially tailored for flue gas treatment, with a higher specific surface area.

Energy from Waste

Lime has provided an essential role in treating emissions for traditional utilities for many years – but it’s also essential for many green energy applications. 

Energy-from-waste plants divert municipal waste from landfills to produce energy and reduce greenhouse gases. Quicklime and Hydrated Lime are used for in-flight capture of acid gases in emissions caused by combustion, preventing them from entering the atmosphere as pollutants. 

In addition, many non-lime products from Singleton Birch are used in this market. To comply with emission standards, flue gases produced by energy-from-waste (EfW) incinerators are also treated with products such as powdered activated carbon (PAC), Urea and Ammonia to remove contaminants, such as heavy metals and dioxins, produced at levels above permissible limits.
