Abstract

Disclosed herein are an apparatus and method for gas leakage measurement in a high pressure reactor. In particular, the present invention relates to an apparatus for gas leakage measurement in a high pressure reactor including: a gas inlet; a first valve equipped to one side of the gas inlet; a flowmeter; a pressure gauge measuring an internal pressure of the reactor; a gas outlet; and a second valve, wherein if in internal pressure reaches a preset pressure by closing the second valve and injecting a gas to the reactor through the flowmeter in the state of opening the first valve, the gas leakage status in the reactor is measured through pressure changes in the pressure gauge after closing the first valve.

First claim

What is claimed is:

1. 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.

2. The apparatus for gas leakage measurement in a high pressure reactor of claim 1 , wherein
if the first pressure equalized state is maintained in the state of closing the third valve after reaching to the first pressure equalized state, it is determined that there is no gas leakage in the second reactor and the amount of gas injection in the first pressure equalized state is the amount of gas-leaking in the first reactor.

3. The apparatus for gas leakage measurement in a high pressure reactor of claim 2 , wherein
if a pressure value of the pressure gauge is increased and the first pressure equalized state is maintained even though a the gas is not injected through the flowmeter in the state of closing the third valve after reaching the first pressure equalized state, it is determined that there is no gas leakage in the first reactor and the amount of gas injection in the first pressure equalized state is the amount of gas leaking in the second reactor.

4. The apparatus for gas leakage measurement in a high pressure reactor of claim 3 , wherein
if a pressure value of the pressure gauge is increased in the state of closing the third valve after reaching the first pressure equalized state, the control part decreases the amount of gas injection in the flowmeter to reach a second pressure equalized state, it is determined that the amount of gas injection in the second pressure equalized state is the amount of gas-leaking in the first reactor and it is determined that a difference between each of the amounts of gas injection in the first pressure equalized state and the second pressure equalized state respectively is the amount of gas leaking in the second reactor.
