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 …

Based on the typical SDA FGD performance, the technology should not be applied to fuels with more than 3 lb SO 2 /MMBtu and the cost estimator should be limited to fuels with less than 3 …

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.

Based on the typical SDA FGD performance, the technology should not be applied to fuels with more than 3 lb SO 2 /MMBtu and the cost estimator should be limited to fuels with less than 3 lb SO 2 /MMBtu.

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 …

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 ...

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]. In-depth analysis of these aspects can provide valuable insights for the design and optimization ...

The curve fit was set to represent proprietary in-house cost data of a "typical" SDA FGD retrofit for removal of 95% of the inlet sulfur. It should be noted that the lowest available SO 2 emission guarantees, from the original equipment manufactures of SDA FGD systems, are 0.06 lb/MMBtu. The typical SDA FGD retrofit was based on:

The SDA-FGD system eliminates SO 2 during the swirling movement of flue gas and slurry, necessitating a clear understanding of the swirling state and structure in the system. Fig. 3 shows the gas streamlines and velocity vector distribution of the SDA-FGD reactor under standard operating conditions. The flue gas velocity is the highest in the ...

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.

Other SDA issues include lower SO 2 removal than the technologies we examine below, often significant O&M for slurry atomizers, and just general procedures with preparing and handling lime slurry.

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 …

In conventional SDA FGD systems, all of the reagent is introduced as a slurry to the absorber. The spray dryer functions to evaporate the water in the reagent slurry, providing sufficient wet phase reaction time for high utilization of the lime and alkaline flyash for acid gas emissions control while producing a dry byproduct. Under ...

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.
