The goal is to determine the individual fire risk at the stages of transportation and storage of petroleum products on the example of a typical oil depot in Irkutsk region and to develop measures aimed to reduce the likelihood of leakage of petroleum products and limit the impact of fire and explosion hazards. The research objects are probabilities of adverse fire-related events (the block diagram method was used) and individual fire risks (the regulatory methods were used). Using the event tree method and taking into account the standards requirements, the probability of accident development scenarios was calculated. Consequences of fire-related emergencies were predicted. The calculated distributions of individual fire-related risks at oil products storage facilities made it possible to identify areas of maximum danger for the personnel. The dangers when unloading railway tanks, storing petroleum products in tanks RVS-2000 and filling automobile tanks were investigated. The parameters of negative events were calculated following possible emergency scenarios for the personnel. The distribution of damage probabilities caused by dangerous fire and explosion-related factors at the production site for the most probable emergency scenarios than can develop at railway tanks on a railway overpass, a group of tanks RVS-2000 and automobile tanks was studied. The fire risk value was calculated at each point of the tank farm. Measures aimed to reduce the risk to the personnel in hazardous areas were suggested.

Аннотация. В данной статье описаны виды ингибиторов коррозии и закономерности их применения в зависимости от условий эксплуатации трубопровода. Одним из видов антикоррозионных мероприятий является ингибиторная защита внутренней поверхности трубопроводов, основанная на применении химических реагентов -ингибиторов коррозии. Ведение химической ингибиторной защиты является одним из наиболее эффективных, технологически доступных и при этом экономически целесообразных методов борьбы с внутренней коррозией промысловых трубопроводов. В статье показано, что к ингибиторам коррозии предъявляются определенные требования: это обеспечение требуемого защитного действия как в условиях высоких давлений и температур, так и при обычных условиях -Ключевые слова: Коррозия, ингибитор коррозии, эффективность, оценка, испытание, антикоррозионная защита, адсорбционные и пассивационные ингибиторы. corrosion protection, the adsorptive and passivatsionny inhibitors.

The problem of safety provisioning in technological processes, which aims the reducing the probability of accidents is considered. Classification of technological process states from the point of view of accident prevention system is offered. The set of such states consists of: normal functioning, pre-emergency, emergency and accident. The state of normal functioning and pre-emergency state assume the absence of irreversible changes in the technological processes. It is considered the case when the operator has to form some management actions which are aimed to stabilize the process, when the process is in the pre-accident state. It is shown an example of a data flow diagram, which includes also the human operator, the tracking system, and the system of manual and automatic control in additional to the standard components of such systems. By using the data flow diagram, it is defined the sequence of stages which occur when the process in transferred from the pre-emergency states to the state of normal operation. A method for assessing the possibility of transferring a technological process from a pre-emergency state to a normal operating in proposed. This method consists in estimating the time relation between the available and the necessary for stabilization of the system. The time required for stabilization consists of the time delay of the measuring device, the latency of the operator and the response time of the actuator. The delay time of the measuring device and the response time of the actuator are determined by the conditions of the technological process. The model for estimating the latency of the person is based on the law “force-time” is developed. A study of the boundary cases of the formula for estimating the available and the necessary time is carried out. Stimulation modelling is conducted, which results are used to estimating the ways of optimizing the technological process in order to improve the reliability of the accident prevention system.
