    • Disclosed is a gas turbine power generating system capable of achieving a high output power and a high power generating efficiency under conditions with a small amount of supplied water and less change in design of a gas turbine. A fine water droplet spraying apparatus (11) is disposed in a suction air chamber (22) on the upstream side of an air compressor (2), and a moisture adding apparatus (7) for adding moisture to high pressure air supplied from the compressor (2) is disposed. A regenerator (5) for heating the air to which moisture has been added by using gas turbine exhaust gas as a heat source is also provided. With this configuration, there can be obtain an effect of reducing a power for the compressor (2) and an effect of increasing the output power due to addition of moisture to air (20) for combustion. Further, since the used amount of fuel is reduced by adopting a regenerating cycle, the power generating efficiency is improved.
    • 公开了一种燃气轮机发电系统,其能够在少量供水的条件下和燃气轮机的设计变化较小的情况下实现高输出功率和高发电效率。 在空气压缩机(2)的上游侧的吸入空气室(22)中配置有微细的水滴喷射装置(11),以及将来自压缩机(2)供给的高压空气中的水分添加到水分添加装置 (2)。 还提供了一种用于通过使用燃气轮机废气作为热源来加热已经添加了水分的空气的再生器(5)。 通过这种结构,可以获得降低压缩机(2)的功率的效果,以及由于向空气(20)中添加水分而增加输出功率的效果,用于燃烧。 此外,由于通过采用再生循环来减少使用的燃料量,所以发电效率提高。

    • In a process for producing acrylic acid, wherein propylene and/or acrolein is catalytically oxidized with molecular oxygen in a vapor phase and the gas resulting from the oxidation is cooled and/or absorbed in water to form a crude aqueous acrylic acid, followed by azeotropic distillation to remove the water with an entrainer of a boiling point of no higher than 130.degree. C. on the crude aqueous acrylic acid which may have, upon necessity, undergone removal of aldehydes contained therein to produce acrylic acid purified in that the crude aqueous acrylic acid is substantially dehydrated, the improvement which comprises conducting the azeotropic distillation under such conditions that concentrations of the entrainer and water in the bottom product of the azeotropic distillation are from 5% to 30% by weight and no higher than 0.5% by weight, respectively, where the theoretical number of plates in the azeotropic distillation column for dehydration used and that in the distillation column for separating acetic acid used are preferably from 5 to 20. Highly-purified acrylic acid can thus be obtained from the crude aqueous acrylic acid without causing unfavorable polymerization of acrylic acid.
