[0002] Jet fuel is also known as aviation kerosene, or aviation kerosene for short. Aviation kerosene hydrogenation refers to the conversion of aviation kerosene (jet kerosene) through a hydrogenation process to obtain a cleaner aviation fuel. The hydrogenation process is to react aviation kerosene with hydrogen under the action of a catalyst to remove impurities such as sulfur and nitrogen, and convert some aromatic hydrocarbons and unsaturated hydrocarbons into saturated hydrocarbons, thereby improving the combustion performance and environmental friendliness of aviation fuel. Aviation kerosene hydrogenation technology is an important technology in the field of aviation fuel. It can reduce aviation fuel emissions, improve air quality, and reduce pollution to the environment. At the same time, hydrogenated aviation fuel also has a higher calorific value and stability, which can improve flight efficiency and aircraft performance. Aviation kerosene hydrogenation technology has been widely used in the aviation industry, which is of great significance for achieving sustainable development of the aviation industry and reducing dependence on fossil energy.

[0003] Since hydrogen has a wide explosion limit and low detonation energy, it is a very dangerous medium. Kerosene is a flammable, odorous liquid. The entire production is under high temperature and high pressure. The production process has relatively high requirements on the quality of employees.

A confined space training unit is set up in the new hydrogen buffer tank 16, the fractionation tower 70, the raw material tank 10, and the waste oil pool. The unit includes gas detection equipment, blowers, and pumps to provide trainees with confined space operation skills training.

[0068] For example, a fire-fighting operation training and assessment unit is set next to the outlet of the product pump 21, and the fire-fighting operation training and assessment unit includes a simulated fire extinguisher, a laser receiver and a fire basin. A leakage and poisoning emergency response training and assessment unit is set next to the gas outlet of the distillation tower top liquid separation tank 14, and the leakage and poisoning emergency response training and assessment unit includes a gas mask, a four-in-one gas detector, and a wrench.

[0069] Specifically, the fire-fighting operation training and assessment unit simulates how to conduct emergency response and related processing procedures after a fire occurs in the factory area. After a fire occurs in a chemical plant, if the fire cannot be extinguished quickly, the corresponding valves should be closed quickly, and the shutdown operation should be performed on the DCS system to prevent the leakage of chemical materials and cause greater disasters. The fire alarm should be reported immediately. The leakage poisoning emergency response training and assessment unit simulates the emergency response process after a toxic gas leak occurs in the factory area. Trainees wear gas masks and carry wrenches to the accident site to close the valves. The background performs shutdown operations on the DCS system. Trainees use a four-in-one gas detector to detect harmful gases in the air at the accident site and learn how to use the four-in-one gas detector.

[0070] For example, the DCS control system is equipped with a DCS control cabinet, an engineer station and an operator station.

[0071] Specifically, the operator station can realize the DCS remote control of the equipment. Trainees can operate the DCS system on the operator station. The engineer station can edit and control the configuration and control logic. Different operation items can be configured for each operator station and their operations can be assessed. The hardware equipment of the DCS system is centrally placed in the DCS control cabinet.

[0072] In summary, this set of aviation kerosene hydrogenation physical simulation operation training device shows the overall picture of aviation kerosene hydrogenation equipment in chemical plants, better reflects the actual aviation kerosene hydrogenation process in industry, and enables trainees to understand the production principle of aviation kerosene hydrogenation, the structure and use performance of major equipment. By analyzing the elements of various special operation links, typical operation training units such as hot work, confined space operation, blind plate plugging operation, high-altitude operation, lifting operation, temporary power operation, and earth-breaking operation are constructed on the device. It is also equipped with an emergency handling training unit to achieve virtual simulation training and assessment of special operation links involving operation scope, risk identification, safety measures, on-site verification and management, so as to enhance trainees' safety awareness, safety skills and safety habits. The DCS system equipped with this device can configure different operation assessment items for each operator station through the engineer station and assess the operation of each operator station.
