A system for removal of SO2 from pollution sources by injecting calcined limestone into the exhaust gas system. In a wet scrubber (the most common type), the absorbent, a mixture of water and limestone, is sprayed inside a treatment area onto the flue gas, which rises from the bottom of the absorber area. Most of the SO2 in the gas is absorbed by the droplets of absorbent, and is oxidized into calcium sulfate and calcium sulfite compounds. The used absorbent (waste sludge) is disposed of as solid waste or is sold as a gypsum product. The cleaned flue gas (possibly reheated to avoid corrosive condensation) is released to the atmosphere.
Industry:Weather
A surface that emits or reflects radiation isotropically, according to Lambert's law.
Industry:Weather
A specific finite difference grid discretization designed to cover the entire globe with nearly uniform spacing.
Industry:Weather
A spherical balloon made of metallized polyester film. It uses a valve to produce a fixed overpressure during ascent. The balloon contains surface protuberances to maintain turbulent flow throughout the ascent. It is tracked by a precision radar to obtain accurate wind profile data.
Industry:Weather
A sunshine recorder of the type in which the timescale is supplied by the motion of the sun. It consists of two opaque metal semicylinders mounted with their curved surfaces facing each other. Each of the semicylinders has a short narrow slit in its flat side. Sunlight entering one of the slits falls on light-sensitive paper (blueprint paper) that lines the curved side of the semicylinder. One semicylinder covers morning hours, the other afternoon hours. The sensitivity of the recording paper is variable, and this introduces an uncertainty in the evaluation of the record.
Industry:Weather
A stormy, rain-bringing wind from the southwest or south-southwest in Hawaii. It blows about five times a year on the southwest slopes that are in the lee of the prevailing northeast trade winds. Kona is the Polynesian word for “leeward. ” It is associated with a southward or a southeastward swing of the Aleutian low and the passage of a secondary depression (kona cyclone) from northwest to southeast, north of the islands.
Industry:Weather
A storm of mesometeorological scale; thus, thunderstorms, squalls, and tornadoes are often put in this category.
Industry:Weather
A standard spectrum representing a fetch-limited sea. A development of the Pierson–Moskowitz spectrum, its form depends not only on the wind speed but also on the fetch.
Industry:Weather
A squall that occurs along a squall line. This term is now confined mostly to nautical usage.
