A least squares curve fit of proprietary in-house cost data was defined as a "typical" SDA FGD retrofit for removal of 95% of the inlet sulfur. It should be noted that the lowest available SO2 emission guarantees, from the original equipment manufactures of SDA FGD systems, are 0.06 lb/MMBtu. The typical SDA FGD retrofit was based on:

In most SDA FGD systems, the spray dryer vessel is located upstream of the primary particulate control device (fabric filters are most commonly used due to their SO 2 removal benefits compared to an ESP). Thus the spray-dried by-product is mixed with the normal fly ash produced by the unit. In recent years, and more commonly in Europe, systems ...

The by-product produced from an SDA system is a dry FGD material commonly referred to as SDA material or dry FGD material. Other terms are also used to refer to this material, as noted in Figure 1. This paper uses the term "SDA material" throughout, except where the generic term dry FGD material was used in the review literature.

Fig. 2 depicts the operational principle of the industrial-scale semi-dry SDA-FGD system. Flue gas containing a high concentration of SO 2 is introduced into the system through the inlet located on the top side. Subsequently, the lime slurry droplets are injected into the reactor from the central top position to achieve full contact with SO 2.The reaction between SO 2 and Ca(OH) 2 …

Oxidation (LSFO) — a wet FGD technology and Lime Spray Dryer (LSD) — a semi-dry FGD technology which employs a spray dryer absorber (SDA). In wet FGD systems, the polluted gas stream is brought into contact with a liquid alkaline sorbent (typically limestone) by forcing it through a pool of the liquid slurry or by spraying it with the liquid.

Figure 2 below is a simplified process flow diagram for a spray dryer absorber (SDA) process, a typical semi-dry FGD system. The system is based on absorption of SO 2 from the flue gas into a lime slurry. The plant's particulate matter (PM) control device subsequently removes captured SO 2 from the system as a solid byproduct.

Semi-dry FGD systems utilize a spray dryer absorber (SDA) to contact the flue gas with an aqueous slurry, similar to wet FGD systems, but the slurry has a higher sorbent concentration and finer spray droplets than wet systems.

However, the SDA-FGD reactor still faces challenges, including low SO 2 removal efficiency, incomplete understanding of gas-solid kinetics, and limited knowledge of the heat and mass transfer characteristics within the desulfurization reactor [14].

Spray dryer-based FGD historically has been the most common "dry" FGD technology used in the United States dating back to the early 1980s. However, it is somewhat of a misnomer to call this technology "dry," as a slaked-lime-based aqueous slurry is actually fed to the spray dryer absorber (SDA).
