US7641876B2 - Reduced liquid discharge in wet flue gas

One aspect of the invention relates to a method for removing contaminants from a flue gas stream ( 22 ). The method includes: removing fly ash from a flue gas stream ( 22 ) utilizing a particle collector ( 24 ); contacting the flue gas stream with an alkaline reagent in a wet scrubber ( 26 ); discharging a purge liquid ( 30 ) from the wet scrubber ( 26 ); and, coining at least a portion of

Types

Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units

Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the coustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with

US5915311A - Process for the thermal treatment of waste

The waste material is degasified under the action of heat in a pyrolysis chaer (2). The volatile degasifying products are subjected to afterburning with supply of oxygen in an afterburning chaer (4a or 4b or 4c) designed as a fluidized-bed reactor. The solids discharged from the afterburning chaer (4a or 4b or 4c) are separated off from the flue gas stream in a dust separator (8) and

NID proves attractive for flue gas desulphurisation where

The petroleum coke may have a very high content of sulphur, up to 6-7 per cent. Petroleum coke alone, or mixed with residual oil, will be used as fuel. As stringent demands are put on the SO2 emissions, it was necessary to coine sulphur removal by limestone addition to the CFB with a tail end desulphurisation system, hence the use of NID.
