Flue-gas desulfurization Wikipedia

2021-3-13  A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

Flue Gas an overview ScienceDirect Topics

Flue gas condensation systems are designed in two ways: as a single-stage recuperative shell and tube heat exchanger and two-stage systems with the first stage of the cooling recuperator (dry economizer, DE) and the second stage in the form of scrubber condensing water vapor and cleaning the flue gas (wet economizer, WE). An example of the first type is the installation presented in Fig. 9.1.

Flue Gas Desulfurization an overview ScienceDirect

This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 2H 2 O). Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.

CFD Analysis of a Water Vaporization Process in a

2021-2-2  In this work, the gas–solid flow and water vaporization process are simulated by the method of Euler–Eulerian two-fluid model in a three-dimensional spouted bed, which have a significant influence on the desulfurization efficiency. The results of simulation indicate that the change trends of the particle volume fraction are similar under superficial gas velocities of 0.7 and 0.8 m/s. The

Calcium carbonate Essential Chemical Industry

2 天前  For example, limestone and quicklime are used to remove sulfur dioxide produced in the burning of coal in power stations. Even 'clean' coal can contain about 1% sulfur. The gaseous effluents, flue gases, from the burning of the coal are passed through a spray of very finely ground limestone or quicklime suspended in water.

Flue gas treatment technology Britannica

2 天前  Flue gas treatment, a process designed to reduce the amount of pollutants emitted from the burning of fossil fuels at an industrial facility, a power plant, or another source. Flue gas—the emitted material produced when fossil fuels such as coal, oil, natural gas, or wood are burned for heat or power—may contain pollutants such as particulates, sulfur dioxide, mercury, and carbon dioxide.

Scrubber Wikipedia

2021-3-18  Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.
