Recently, Beijing Gas Group, an important partner of Hanhai Opto-electronic, and GTT of France signed a cooperation agreement on the Tianjin Nangang LNG receiving station project at the French Embassy in China. This cooperation agreement mainly involves the cooperation between the two parties in the second and third phases of the Nangang LNG project, including the new construction of six 220,000 cubic meters of ultra-large film LNG full-contained tanks using world-leading technology.

Beijing Gas Group, an important partner of Hanhai Opto-electronic, is subordinate to Beijing Enterprises Group and is one of the largest gas companies in China.

As an important partner of Beijing Gas Group under the Beijing Enterprises Group, Hanhai Opto-electronic is a major scientific research achievement transformation organization of the Chinese Academy of Sciences, dedicated to the application of laser absorption spectroscopy technology for accurate gas detection. The company's products and technologies can be applied to safety monitoring in fields such as oil and gas pipeline networks, coal mines, urban gas, offshore drilling platforms, chemical plant areas, storage and transportation of hazardous chemicals, LNG storage and transportation, and fire protection, as well as industrial process control, such as industrial boilers. And other fields.

The company’s relevant core technology has broken the European and American technology monopoly, and has been jointly recommended by the Ministry of Emergency Management, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology. Product certification, emergency management department safety production technology achievement award and many other achievements.

The series of products have been applied in large domestic energy companies such as PetroChina, CNOOC, Beijing Gas Group, Hong Kong and China Gas Group, China Gas Group, China Resources Gas Group, etc., and the world's largest laser gas leakage monitoring network has been established in Beijing.

According to national regulations, fixed-point combustible gas detectors must be installed in gas stations. The passive optical fiber laser leakage monitoring system can be used to replace the existing traditional combustible gas detectors. Just install the passive light sensing terminal directly where the traditional combustible gas detector was originally installed.

The passive optical fiber laser leakage monitoring system is a passive online monitoring system, mainly for 24 hours remote online monitoring for places without electricity, high humidity, and unmaintainable. The system is composed of a system host and a passive light sensing terminal. The system host and the light sensing terminal are connected by optical fiber, and the optical fiber transmission distance can reach 20KM.

The monitoring site only needs to place a passive light sensing terminal, and the monitoring site can realize 24-hour online monitoring without any power. First, it solves the problem that many important safety nodes and confined spaces cannot be monitored due to lack of electricity. Secondly, it prevents the traditional monitoring equipment itself from being charged and may become an inducement risk for explosion accidents.

As early as 2015, Hanhai Opto-electronic assisted Beijing Gas Group to install a total of more than 30 fixed scanning laser gas telemeters in all high-voltage stations, and established the first international laser telemetry monitoring network for it, realizing all the high voltages for Beijing Gas The pressure regulating station carries out laser telemetry.

Beijing Gas Group stated that the use of laser detectors has greatly reduced the labor intensity of inspectors, improved management efficiency, and realized unattended operation in the true sense. In the future, pressure regulating stations and gas filling stations will be installed in the city gas pipeline network. , Pipeline wells and other important leaky and dangerous nodes for larger-scale applications.

Regarding the cooperation between Beijing Gas and the Tianjin Nangang project, Li Shuguang, chairman of Hanhai Opto-electronic, first congratulated the companies of both parties and said that as Beijing accelerates the pace of low-carbon transformation, natural gas accounts for 33% of Beijing’s energy structure. Become an important energy variety to ensure the operation of Beijing city. As an important part of the country's establishment of a natural gas storage system that combines diversified gas storage and hierarchical peak shaving, the Nangang LNG terminal project is of great significance to ensure the energy security of the capital and enhance the energy storage capacity of the Beijing-Tianjin-Hebei region.Hanhai Opto-electronic will provide technical guarantee for LING's safe production.
