SEPARATING COLUMN FOR HIPPURIC ACID ANALYSIS, LIQUID CHROMATOGRAPH FOR HIPPURIC ACID ANALYSIS, AND METHOD FOR ANALYZING HIPPURIC ACID

Номер: WO2019198280A1
Автор: TAMAGUCHI Tadayuki, FUJIMURA Daiki, OTSUKI Hideyuki
Принадлежит:

This separating column (12) for hippuric acid analysis is filled with a filler in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to a silica matrix. By using such a filler for the separating column (12) in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to a silica matrix, it is possible to separate a hippuric acid, an o-methyl hippuric acid, a m-methyl hippuric acid, a p-methyl hippuric acid, and a mandelic acid without using a mobile phase containing cyclodextrin.

The intermittent operation processing step includes: a no-load operation step in which a gas turbine is operated with no load, with a steam stop valve and a bypass valve closed; during the no-load operation step, a pressure accumulating step in which steam is accumulated in a pressure accumulation region; and, after the pressure accumulating step, an intermittent blowing step in which the bypass valve is opened, and steam in the pressure accumulation region is allowed to flow into a condenser. The commissioning processing step includes: a commissioning step in which the gas turbine is commissioned with the steam stop valve closed and the bypass valve open; and a continuous blowing step in which steam from a waste heat recovery boiler is allowed to flow into the condenser.

Abstract Object Provided are a control device for a gas turbine, a gas turbine facility, and a method for controlling a gas turbine, which can effectively prevent a turbine inlet temperature from exceeding a limit value when the rotational speed of the gas turbine rapidly decreases. Solving Means A control device for a gas turbine includes a fuel command value calculation unit that calculates a fuel command value to be given to the gas turbine. The fuel command value calculation unit includes a rotational speed rapid decrease detection unit configured to detect a rapid decrease in a rotational speed of the gas turbine based on a temporal change amount of the rotational speed of the gas turbine and a fuel command value limiting unit configured to limit the fuel command value in response to a decrease in the rotational speed when the rotational speed rapid decrease detection unit detects a rapid decrease in the rotational speed of the gas turbine.

Eine Steuervorrichtung (100) umfasst eine Betriebsart-Erkennungseinheit (127), die erkennt, ob eine Startbetriebsart einer Dampfturbine eine Kältebetriebsart ist, in welcher eine Temperatur eines Dampfkontaktabschnitts der Dampfturbine niedriger als eine vorbestimmte Temperatur ist, oder eine andere Startbetriebsart ist, in welcher die Temperatur des Dampfkontaktabschnitts gleich oder höher als die vorbestimmte Temperatur ist, einen ersten Öffnungsgenerator (121), der einen ersten Öffnungsgrad größer als ein zweiter Öffnungsgrad in der anderen Startbetriebsart als einen Öffnungsgrad eines Ansaugluftregulators (14) eines Kompressors während einer Periode erzeugt, nachdem die Erzeugung von Dampf aus einem Abwärme-Rückgewinnungskessel gestartet worden ist, und bevor die Zufuhr des Dampfes zu der Dampfturbine gestartet wird, und eine Befehl-Ausgabeeinheit (128), die einen Befehl korrespondierend zu dem ersten Öffnungsgrad an den Ansaugluftregulator (14) während der Periode ausgibt, wenn die Betriebsart-Erkennungseinheit (127) erkennt, dass die Startbetriebsart die Kältebetriebsart ist.

A separating column (12) for hippuric acid analysis is filled with a filler in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to a silica matrix. By using such a filler for the separating column (12) in which 123 μmol/g or more of β-cyclodextrin is chemically bonded to the silica matrix, hippuric acid, o-methyl hippuric acid, m-methyl hippuric acid, p-methyl hippuric acid, and mandelic acid can be separated without using a mobile phase containing cyclodextrin.
