Apparatus and method for gas leakage measurement in a high pressure reactor

An apparatus for gas leakage measurement in a high pressure reactor, the apparatus for measuring the amount of gas-leaking and a gas leak point in a plurality of high pressure reactors, the apparatus comprising:

• a gas inlet through which a gas is flowed in a first reactor;
• a first valve which is equipped to one side of the gas inlet;
• a flowmeter which is equipped to a front-end of the first valve and measures a gas flow;
• a pressure gauge which measures internal pressures of the first reactor and a second reactor in real time;
• a gas outlet through which an internal gas of the first reactor is flowed out;
• a second valve which is equipped to one side of the gas outlet;
• a connection pipe which connects the first reactor and the second reactor;
• and
• a third valve which is equipped to one side of the connection pipe,
• wherein the gas leakage status in the first reactor and the second reactor is measured through pressure changes in the pressure gauge by opening the first valve and the third valve and injecting a gas into the reactors by the flowmeter in the state of closing the second valve,
• wherein the flowmeter has a reverse flow protection function so that the gas is only flowed in the reaction side, and comprises a recorder on which is saved a pressure value measured in the pressure gauge in real time to record changes,
• wherein if an internal pressure reaches a preset pressure by closing the second valve and injecting gases to the first reactor and second reactor in the state of opening the first valve and the third valve, the amount of the gas injected through the flowmeter is adjusted to zero to prevent further gases from being injected and the gas leakage status in the reactors is then determined through pressure changes in the pressure gauge,
• wherein if a pressure value is decreased in the state of adjusting the amount of the gas injected through the flowmeter, it is determined there is a gas leakage in the first and second reactors, and
• wherein the apparatus for gas leakage measurement further comprises a control part which controls the flowmeter to reach a first pressure equalized state by injecting a gas through the flowmeter, and determines that the amount of gas injection in the first pressure equalized state is the amount of gas-leaking of the first and second reactors.
