Advanced Energy Equipment Technology Research Institute "Key Technology Research of Natural Gas Liquefaction Plant Construction" entered the experimental test stage

Liquefied natural gas pipeline and storage tank test site

Since October 2015, the Tianjin High-end Equipment Research Institute of Tsinghua University (referred to as the "High-end Institute") Advanced Energy Equipment Technology Research Institute (referred to as the "Advanced Energy Institute") has undertaken the installation company of PetroChina Daqing Oilfield Engineering Construction Co., Ltd. (referred to as the installation company) "Research on Key Technologies for Natural Gas Liquefaction Plant Construction" project. After several months of continuous research, the project has entered the experimental test stage from the stage of scheme design, calculation and analysis.

The temperature of liquefied natural gas can be as low as_162 ℃, so the transportation and storage of liquefied natural gas is the main technical problem in the natural gas liquefaction plant, and ensuring the safety of the storage and transportation process and improving its economy is the main technical key of the liquefied natural gas project. During the cooperation with the installation company, the Advanced Energy Institute gave full play to its technical advantages, steadily promoted the design and optimization of the scheme, and the research and development work was fully recognized by the cooperative units. At present, the project is progressing smoothly, the design of the scheme has been completed, a number of key technical measures have been demonstrated and implemented, the project has entered the experimental testing stage, and phased progress has been made.

Natural liquefaction plant is a very important link in the LNG industry chain. The LNG industry chain is a complete chain system with huge capital and intensive technology that runs through the whole process of the natural gas industry. Due to the needs of environmental protection, it is estimated that in 2020, my country's annual import of natural gas will reach 30 million tons, which makes my country have a huge demand for natural gas storage and transportation.

Daqing Oilfield Construction Co., Ltd. is a comprehensive engineering construction enterprise with special qualification for general contracting of chemical petroleum engineering construction. It is the largest engineering construction enterprise in China. The company's business scope includes chemical petroleum construction, construction, road and bridge construction, product prefabrication, engineering design, etc. The five main businesses, the construction field covers 23 provinces, autonomous regions and municipalities directly under the Central Government in China, and has successively entered Pakistan, Bangladesh, Iraq and other countries and regions.
