    摘要: 2R-dodecyl 2-(N,N dimethylamino)-propionate (R-DDAIP) provides an unexpectedly improved activity in facilitating transport of a pharmaceutically active compound across biological membranes and tissues, compared to S-DDAIP of the same enantiomeric purity, or racemic DDAIP. Purified S-DDAIP is also provided.

    摘要: An ammonia injection grid for a selective catalytic reduction (SCR) system that provides uniform distribution of ammonia to the SCR catalyst in NOx reduction systems for heat recovery steam generation systems, packaged boilers, simple cycle catalyst systems and fired heaters for superior operational efficiency. The ammonia injection grid includes an injection tube having at least one nozzle for injecting ammonia into a flow of flue gas. The ammonia injection grid also includes a corrugated turbulence enhancer associated with the injection tube to generate turbulent wake to enhance turbulent mixing.
