The Tai'an Shenran LNG plant primarily adopts many domestic technologies for its LNG process and its applied equipments are all made in China. This paper first makes a detailed introduction to how this plant chooses the expansion refrigeration for natural gas liquefaction process according to the compositions of feedstock natural gas, the supply condition, and the processing capacity, and taking into account many factors including the investment cost, energy consumption, operational flexibility, order production cycle of equipments, and so on. Then, in aspects of technology, process and equipments, etc. , technical characteristics are analyzed of purification, liquefaction, storage and transportation, utility system, and autocontrol instrument. Technical innovations are summarized as follows: the CO_2 removal by the MDEA solution in the Oxyamine process, adsorption dehydration by the isopiestic method,and mercury & benzene removal by the activated carbon in the purification unit,' and dual-expander in parallel in the liquefaction unit.Finally, in comparison with the advantages and disadvantages of the liquefaction process in other LNG plants, this paper points out the technical and economical superiorities of the applied domestic technologies and equipments in the Tai'an Shenran LNG Plant. This study provides reference for similar LNG plants in China.
