Many chemical accidents are caused by gas leakage, and gas leakage can also damage the atmospheric environment. For the leakage of liquefied natural gas, liquefied petroleum gas, liquefied ethylene, etc., it is colorless and odorless and cannot be detected by the naked eye. At the same time, since it is difficult to detect the leak point of the seal, there is a danger that the inspector will come into close contact with the toxic gas. At this time, if you want to determine the location and scale of the leak, a gas leak detection infrared camera is a very good choice. Thermal imaging cameras, which allow people to "see" gas and quickly pinpoint leaks, have revolutionized maintenance in many industries over the past few decades and have played a very important role in reducing environmental damage.
1. Advantages of using IR thermal imager for gas leak detection
Early gas leak detection methods used mechanical probes, which required the inspector to be in close contact with the detected object, and the inspector may be exposed to invisible harmful chemicals. At the same time, this detection method also has requirements for the detection site, and there are certain problems in achieving all-round detection in 24 hours.
The use of gas leak detection IR thermal imager can carry out fixed-point large-area detection. The IR thermal imager detects gas leakage through the temperature change in the outside world when the gas is excluded. When the leaking gas occurs, it can be judged by observing the IR thermal imager. Find out the location and size of the leak for further treatment. With the advantages of long-distance non-contact, 24-hour monitoring, and intuitive visualization, it has become an important tool for gas leak detection.
2. Industry application of gas leak detection IR thermal imager
(1) Refining
A typical refinery includes two types of process flow: separation and conversion. The separation process cracks crude oil into useful components, either directly sold as fuel or used as feedstock for the next process. The conversion process modifies the molecular structure to provide a product with suitable properties suitable for blending with finished fuels. Thermal imaging cameras can respond well to "light fractions" and intermediates produced in fuel processing plants. A general rule of thumb is that thermal imaging cameras can monitor volatile gases during crude oil fractionation.
(2) Petrochemical
The industry that produces hydrocarbons, whose raw materials come from the separation process or conversion process of petroleum refining, uses thermal imaging cameras for gas leak detection to detect gas leaks in the petrochemical production process.
(3) Chemical industry
Production of non-hydrocarbon or inorganic chemicals from basic feedstocks, typically in batch and continuous processes in the chemical industry, yields high product purity. MWIR cameras for gas leak detection have good responsiveness for some chemicals in the industry.
(4) Power station
Gas power plants usually use natural gas as fuel. MWIR thermal imaging cameras for gas leak detection are ideal for leak detection in this industry.
(5) Natural gas
Natural gas is mainly composed of methane and ethane. During the production, storage, transportation and distribution of natural gas, mid-wave IR thermal imagers are suitable for leak detection in all links from production to distribution network to end consumers.
(6) Environmental law enforcement
In many countries, enforcement is generally carried out by government agencies rather than by industry regulation. These agencies use thermal imaging cameras for gas leak detection to monitor industries, ensure compliance with regulations, and are responsible for auditing their emissions reduction performance.
Thermal imaging technology for gas leak detection has a wide range of potential uses, it offers time and cost advantages over traditional methods such as "sniffers" and can identify leaks at a distance without having to monitor all suspected leaks Go to the scene to confirm one by one, reducing the risk of detection. Thermal imaging cameras can visualize gas leaks and pinpoint them, avoiding unnecessary operational downtime. By continuously scanning remote areas, you can know immediately when a dangerous gas leak occurs, so you can take immediate action.
