DEHA is largely used as an oxygen scavenger in water treatment.. It is a volatile oxygen scavenger [2] [3] and reacts in a ratio of 2.8/1 DEHA/O2.It is employed in high pressure (>70 bar) boiler systems due to a very low rate of reaction at low temperatures and pressures.
Combination boilers are popular in Europe where market share in some countries is in excess of 70%, with a projected rise in the United Kingdom to 78% by 2020. [3] This trend is attributed in part by a social trend towards more numerous but smaller households and an ever-increasing trend towards physically smaller and often high density housing.
Electrode boilers can work on both single-phase and three-phase supplies. If DC voltage is used, electrolysis of water occurs, decomposing water into its elements H 2 at the cathode (negative electrode) and O 2 at the anode (positive electrode). The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. [1]
LY294002 is a morpholine-containing chemical compound that is a potent inhibitor of numerous proteins, and a strong inhibitor of phosphoinositide 3-kinases (PI3Ks). [1] It is generally considered a non-selective research tool, and should not be used for experiments aiming to target PI3K uniquely.
Diethylethanolamine is used as a corrosion inhibitor in steam and condensate lines by neutralizing carbonic acid and scavenging oxygen. Diethylethanolamine reacts with 4-aminobenzoic acid to make procaine. DEAE is a precursor for DEAE-cellulose resin, which is commonly used in ion exchange chromatography.
Antiscalants are also known as scale inhibitor agents. Scale formation occurs when the concentration of dissolved salts in water exceeds their solubility limits, leading to the precipitation of these salts onto surfaces as hard deposits. Antiscalants dissolve the substances accumulated near the membrane surface and reduce the rate of fouling. [1]
Some types of boilers aren't used for heating, but for other purposes. A boiler could be used as a household appliance or to produce steam for an industry. An electric steam boiler is intended to produce steam for process industry or other uses, such as drying, heat treating, and others. These are generally permanently installed systems with ...
NACE International Standard TM0208 defines volatile corrosion inhibitor (VCI) as a chemical substance that acts to reduce corrosion by a combination of volatilization from a VCI material, vapor transport in the atmosphere of an enclosed environment, and condensation onto surface in the space, including absorption, dissolution, and hydrophobic ...
