21/01/2019 In Co. Roscommon, spreading only is costing €6/t, spreading and loading will cost up to €8/t, while the cost of the product itself is €17/t. Lime from one outlet in Co. Kilkenny is costing €20/t, while it can be delivered and spread to anywhere in the south-east of the country for €25/t.
27/12/2010 Its worth offering a breathable alternative to lime that will have a significant cost saving. check why they specified lime and what they require from the render perfomance wise, it may be a case that the architect or whoever is unaware of the alternatives.

Wet lime scrubbing: The wet lime sorption process combines the advantages of gas scrubbers and (semi) dry lime sorption. This industrial gas removal technique is especially applied for the desulphuration of smoke gases whereas also the other acid forming components are bound. At wet lime sorption slurry of limestone (CaCO 3) becomes misted in spray column. In the presence of SO 2 gypsum (CaSO ...
Spent scrubbing liquids are sent to a clarifier, where much of the water is reused. Spent solids are removed in a heavy slurry to a settling pond. The water (with makeup fresh water, as needed) is returned to the scrubber. A pH sensor in a recirculating tank is used to control feed of solid lime or limestone. Neither lime nor limestone dissolves well in water and therefore, both are pumped in ...
Lime / Limestone Wet Scrubbing System for Flue Gas Desulfurization Background Process Instrumentation Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO 2) and other pollutants from gas streams. Undesirable pollutants are removed by contacting the gases with an aqueous solution or slurry containing a sorbent. The most common sorbents are lime
12/02/2005 SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...

Flue gas desulfurization: conceptual process design and cost estimates for lime/limestone wet scrubbing
Including scrubber modifications the capital investment is 15.4 $/kW and the annual revenue requirements are 1.18 mills/kWh. These relative cost differencies remain for variations in power plant size, coal sulfur and ash contents, power plant age, distance to the disposal site, and lime instead of limestone scrubbing. In comparison to processes ...
The sorbent most desirable is the hydrated lime for flue gas scrubbing. Gebhardt, in U.S. Pat. No. 6,331,207, issued Dec. 18, 2001, teaches a method of treating cement kiln dust for recovery and recycle. In the patent, it is indicated that the supply of cement kiln dust may be moistened and subsequently treated with carbon dioxide to convert the materials to carbonates. During the carbonation ...

Most pH sensors tend to coat in scrubbing applications, especially in applications that use lime (Ca(OH) 2) as the scrubbing chemical. To minimize coating effects, make sure that the sensor is mounted in a high flow area (in-line > 3 ft/sec velocity is suggested). The use of flat-surface, self-cleaning pH sensors ORP sensors or differential pH ORP electrodes is recommended to reduce the ...
26/01/2018 The operating cost was evaluated starting from a hydrated lime cost of €83/t and a power cost of €41.40/MWh. A higher power cost would further penalise the wet FGD technology, which is the most energy-demanding in this comparison. From a technical point of view, it should be noted that while the byproduct coming from the wet FGD is recoverable in cement grinding in the place of gypsum (the ...

The lime used in the aqueous scrubbing slurry may be a high calcium lime or a lime containing magnesium, such as a lime described in the aforementioned U.S. Pat. No. 3,919,393, containing about 2-10 present by magnesium oxide. As with the sodium ions, the magnesium ions are effected by the chloride ion content of the aqueous media, and the amount of magnesium ion present in the scrubbing

The scrubbing liquid is controlled to a neutral pH with reagent addition to drive SO2 absorption. Caustic soda (NaOH) is typically used as the alkaline reagent. However, other alkalis such as soda ash and magnesium hydroxide have also been utilised with excellent results in terms of performance and reliability. In non-refinery applications and in extremely few refinery applications, lime has ...
25/09/2009 Lime or limestone slurry scrubbing for flue gas desulfurization was first applied at two British plants in 1936 , and was identified as an effective technology as early as 1965 . However, it was deemed to have unacceptable capital cost, poor reliability, and poor environmental performance, as well as being too commercial, and therefore was considered an unworthy candidate for government-funded ...
