Currently, there is no single universal tool that would comprehensively calculate both flare systems and oil and gas treatment facilities. When designing new flare units or optimizing the operation of existing ones, software developed by various companies is used. It should also be noted that the calculations of flare systems are regulated by regulatory documents and GOSTs of the Russian Federation. Rosneft Oil Сompany developed the technological process modeling simulator RN-SIMTEP, designed to calculate the object parameters for well products gathering, treatment and transportation systems, including flare units, in accordance with the standards of the Russian Federation (certificate of compliance № ROSS RU.04PLK0.OS01.N00035). The tool is designed to solve problems at the stages of field design and operation and enables developing a project in a unified technological environment – from conceptual design to design and exploration work and production. The paper presents the features of various software tools for calculating flare systems. The comparative analysis includes calculation of flare header hydraulics, as well as thermal radiation and pollutant emissions. Unlike foreign and domestic analogues, RN-SIMTEP offers a wide range of methods for calculating flare systems in accordance with regulations of the Russian Federation, as well as the possibility of joint calculation of the flare system with oil and gas treatment. Thus, the tool enables reducing the financial costs of purchasing several software, the labor costs of transferring data from one software to another and minimizing errors caused by manual transfer.
