Yoseen infrared is a company focusing on the R & D, production and sales of temperature - measuring infrared thermal camera. Our thermal cameras are widely used in human body temperature measurement, metallurgy, power system, security and other fields.
System introduction

Petroleum chemical production is different from other industry, the characteristics of many important devices are working under high temperature and high pressure conditions, and for the most is the process cycle run long, plus the petrochemical production itself inherent risk (inflammable, explosive), the industrial production has always attached great importance to the production process, strict monitoring of security and reliability of the device itself inspection and regular shutdown maintenance. At the same time, as a comprehensive enterprise, in addition to the normal petrochemical equipment, there are auxiliary equipment such as electricity, electrical appliances and raw material chemical. Infrared thermal imaging system is an ideal choice for early detection of problems, safe operation and long service life of equipment. Infrared thermal camera imaging principle is based on temperature difference to imaging, as long as the measured object has a temperature difference of 0.05 degrees, infrared thermal camera monitoring system can distinguish it and imaging intuitive display.


System Overview

Crude oil, refined oil, natural gas, and refined or synthetic chemical raw materials are inflammable and explosive articles. In the process of production, storage and transportation, it is very easy to cause fire, explosion and other safety hazards. Any ignition or unusually high temperatures are a cause for alarm. Infrared thermal camera can not only detect the ignition on the body, but also detect foreign fire entering the restricted area. Infrared thermal imaging technology is a non-contact temperature measurement of high-tech detection technology, its collection of photoelectric imaging technology, computer technology, image processing technology, by receiving the infrared radiation emitted by objects, its thermal image display on the screen, so as to accurately judge the temperature distribution on the surface of the object, has the advantages of accurate, real-time and fast. It is especially suitable for such large space and open air monitoring to provide early warning signal of fire with intuitive thermal image. Cooperate with the existing means, the customer's fire protection system will be more perfect to the monitoring of safety hidden trouble.


Infrared thermal imaging system consists of front-end thermal image acquisition system, data transmission system, data analysis server and client. With visual, remote view, no contact, 24 hours real-time monitoring and warning and other characteristics, can avoid the timely discovery of heavy losses. Infrared thermal cameras applied in petroleum and petrochemical refining plant: In the refining plant, the thermal imager continuously scans and detects the operating area, warns and locates the abnormal high temperature area, and prevents leakage and explosion events; Oil and gas storage: In the tank area and transfer station, the thermal imager monitors the tank body, valve body, pipeline and isolation zone to prevent the ignition of oil and gas leakage;

Oil and Gas Transportation

The flammable gas is most likely to leak into the air during oil and gas transfer. Use thermal image to monitor the working area, and start alarm immediately if any external fire or abnormal temperature is found;

Chemical storage: In a large storage warehouse for chemical products, only a few thermal imagers can cover a warehouse, providing reliable and stable early fire warning with approximately zero false positives.


Monitor the Status of Key Equipment

Key equipment condition monitoring Compressor, reactor and so on are the key equipment in petrochemical industry. Temperature is one of the important indicators to reflect the working state of the system. By monitoring the temperature distribution on the surface of the equipment, the working state of the equipment can be understood immediately. Once the system temperature is abnormal, an alarm will be given immediately to prevent the equipment from going down, which will lead to production interruption and threaten production safety. The reactor is usually operated under high temperature and high pressure, and the consequences of accidents are often very serious. Real-time monitoring of the temperature field on the outer surface of the reactor and analysis of its temperature variation potential, can evaluate the internal refractory thickness or scaling, and help managers to make production and maintenance plans; At the same time, it can avoid accidents.


Monitoring of Hot Oil Leakage in Waste Liquid Incinerator

In the production process of chemical enterprises, a large amount of organic waste liquid is produced, which is mainly treated by waste liquid incinerator. There are risks in the hot oil circulation system, such as hot oil leakage in the hot oil pump body, hot oil leakage in the furnace head pipeline, and oil leakage in the Swaglok instrument group gauge head. If not found in time, the hot oil will easily cause fire once it comes into contact with the high-temperature furnace body, threatening the safety of the plant.


The infrared thermal image monitoring system can monitor these key locations 24/7. By setting the temperature threshold or temperature rise rate, the leakage danger can be discovered in time and an alarm can be given to inform the person in charge to deal with it in time so as to avoid fire.


Equipment Inspection and Status Maintenance

Electrical equipment and distribution systems in petrochemical enterprises, including high voltage contactors, fuse plates, main power circuit breaker plates, contactors, and all distribution lines, motors, transformers, etc., may have latent heat hazards that, if not detected in time, may cause unplanned equipment shutdowns or even fire.


Perimeter Security Monitoring

Oil depots, gas stations and refining and chemical plants are all safe places. Irrelevant personnel are not allowed to approach or enter. The current security situation is grim, these security centers are likely to become the target of attacks. At present, perimeter protection is mainly carried out by electronic fence plus vibration cable or infrared radiation. However, excessively high false alarm rate causes headache for duty staff and managers, so that the alarm function is directly turned off in most cases. Some places will also be equipped with CCTV hd cameras for surveillance, but in dark or foggy weather, CCTV surveillance will be completely useless, and the personnel on duty must have a strong sense of responsibility, otherwise, criminals may "walk" into "restricted areas".

The User Benefit

Infrared thermal imaging monitoring system has low false alarm rate, wide monitoring range, self-defined perimeter and automatic intrusion alarm. It can also carry out security protection for perimeter even in the dark and foggy weather of "invisible fingers". Gas leak detection refineries need the help of cutting-edge technology to ensure absolute environmental and operational safety. Infrared thermographs can also be used to identify volatile organic compound (VOC) leakage sources to ensure timely repair of leaking components. The most advanced VOC detection means can ensure the enterprise to improve the safety of operation, improve production efficiency and maximize the elimination of all kinds of leakage potential, do a good job of prevention and remedial measures.
