Spray-Dry Desulfurization of Flue Gas from Heavy Oil

Flue gas desulfurization (FGD) by spray-dry absorption in conjunction with baghouse particulate collection has been indicated to be a viable alternative to wet scrubbing in boilers burning low- to medium-sulfur (S) coal or fuel oil, or in waste incinerators.1–6 The ad-vantages of spray-dry FGD over other technologies in-clude

Flue gas desulphurization by spray dry absorption

Jan 01, 2000 The spray dry absorption experiments are performed with a laboratory scale spray dryer with an inner diameter of 0.16 m and variable length. Most of the experiments are conducted with a spray dryer length of 1.5 m. In order to examine the influence of the residence time on the absorption efficiency some experiments are performed with lengths of ...

Process Description of Spray drying based Semi-Dry Flue Gas Desulphurization System. The process consists of large chamber in which absorbent liquid is sprayed and made to react with SO 2 in the incoming flue gas to produce reaction products in form of particulates; The exhaust gas is then passed through bag filter to remove residual particulate matter and clean gas is …

Salt Drying Technology for Zero Liquid Discharge

Spray drying is a process in which a liquid or slurry solution is sprayed into a hot gas stream in the form of a mist of fine droplets.(Geankoplis, 2003) In power generation, spray dryers are most commonly used in spray dryer absorption (SDA) applications in which an alkaline slurry is used to remove acid gases from a flue gas stream.

Sulfur oxides control technology series: Flue gas

The ACP uses a spray dryer flue gas desulfurization (FGD) system and molten salt reduction with coal to make sulfur. For a 500-MW power plant burning 3.5% sulfur coal, capital investments for the ACP and the Wellman-Lord (acid, Resox, and Allied) processes are $119, $131, $138, and $141/kW, respectively.

Optimize Spray Dry Absorption with Rotary Atomizers

Optimize Spray Dry Absorption with Rotary Atomizers

The rotary atomizers were used to spray water to maintain a temperature below this permitted temperature. The plant struggled with operating the SDA’s to cool the gases, so that the temperatures could be kept below 300F. The Atomizer also had issues with hopper wetting and this de-rated the boiler in multiple instances.
