Annotation:

At the current stage of development of the domestic industry there observed a growing interest in the production of liquefied natural gas (LNG) using low-tonnage units. In the process of design, construction and operation of small-capacity LNG plants, modern technologies are introduced, which impose higher requirements to the qualification of operational personnel, requiring the use of new approaches to training specialists. The authors of the article consider the experience of introducing a computer simulator in the process of training process operators at small-capacity LNG plants. The computer simulator reflects the basic physical laws; it has the functions of formation and visualization of the calculation scheme of continuous technological processes (TP) of natural gas low-tonnage liquefaction, control system, simulation modeling of technological objects as well as the system of a trainee's actions evaluation. The developed computer simulator allows using complex tools to steadily form the required set of operational personnel knowledge and skills, to increase the safety level, efficiency of operation and reduce the risk of abnormal and emergency situations occurrence. When developing approaches to training operational personnel using a computer simulator, special attention was paid to ensuring a thorough understanding of the physical principles of natural gas liquefaction and the interaction of various plants elements. The authors of the article detail the benefits of introducing such simulators, including the safety of experiments to investigate plant operational modes, the ability to quickly assess the aftereffects of actions and improved training and practical skills of personnel. The results of computer simulators introduction into the training process are analyzed and their role in reducing risks and improving the overall efficiency of production operations is emphasized. The information presented is useful for employees of educational institutions and industry specialists interested in the development of low-tonnage LNG production technologies that promote efficient and safe operation.
