Selection of the base load technology is a very important step on the way of future LNG project development. Therefore, it is necessary to pay attention to technology selection principle. In this paper, we considered literature according to the matter. Modernization of proposed in 2010 decision scale of assessment became the result of the literature review. In the Thesis, the matrix was created for the project, which has not have final investment decision yet, Baltic LNG project. It will be located in Russia, on the territory of Leningrad region. Filled matrix showed three the most suitable technologies. These technologies are AP-C3MR, Shell DMR and Statoil-Linde MFC. During simulation procedure, all necessary refrigerants compositions, which can guarantee adequate results of the simulation process, were revealed. Simulation results showed that AP-C3MR is not very suitable technology because it has a high value of relative to DMR specific work (1.08) and situated on the third place in the decision matrix, while DMR and MFC have values of 1.00 and 1.03 and stay on the second and first place respectively. A detailed comparison of different parameters of other two processes concluded that DMR process has more chances to be implemented as a basis of Baltic LNG project.
