Background of the project
Petrochemical refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. Petrochemical products are obtained through chemical processing of feedstock oil provided by the refining process. The first step in the production of petrochemical products is to crack raw oil and gas (such as propane, gasoline, diesel, etc.) to produce basic chemical raw materials represented by ethylene, propylene, butadiene, benzene, toluene, and xylene. The second step is to produce more than 200 kinds of organic chemical raw materials and various synthetic materials with basic chemical raw materials.
In addition to the petrochemical industry, chemical fertilizer industry, man-made fiber industry, synthetic resin and plastic industry, paint industry, cleaning supplies industry, man-made fiber textile industry, knitting industry, rubber product industry and other petrochemical-dependent industries are also closely related to people's food, clothing, housing, rows are closely related. About 70% of the hardware parts of precision products such as parts, shells, tires, chemicals, etc. come from the petrochemical industry.
dangerous gas
The materials involved in petrochemical production are highly dangerous, and the probability of fire, explosion, and mass death and injury accidents is high. Petrochemical production, from raw materials to products, including semi-finished products, intermediates, various solvents, additives, catalysts, reagents, etc. in the process, most of them are flammable and combustible substances, as well as explosive substances such as crude oil, natural gas, gasoline , liquid hydrocarbons, ethylene, propylene, etc. Most of them exist in the state of gas and liquid, and are easy to leak and volatilize. Many materials are highly toxic and highly toxic substances, such as benzene, toluene, sodium cyanide, hydrogen sulfide, chlorine, etc., and these materials are improperly disposed or leaked. , easily lead to casualties. In the petrochemical production process, a variety of highly corrosive acids and alkalis are also used and produced, such as sulfuric acid, hydrochloric acid, caustic soda, etc. The possibility of corrosion problems in equipment and pipelines is high; some materials also have the characteristics of spontaneous combustion and violent polymerization. Such as metal organic catalysts, ethylene, etc. Especially in the production process, the process operating conditions are harsh, including high temperature, cryogenic, high pressure, and vacuum. Many heating temperatures reach or exceed the spontaneous ignition point of the substance. Once the operation is wrong or the equipment is out of repair, fire and explosion accidents will easily occur. In addition, as far as the current technological level is concerned, in many production processes, materials need to be heated with an open flame; in addition, daily equipment maintenance requires frequent fires. This constitutes an outstanding contradiction, that is, fear of fire and the need to use fire. In addition, the reserves of flammable and explosive substances in various enterprises and devices are large. Once they are not handled properly, accidents will occur, and the consequences will be disastrous. The accidents have fully proved this point. In addition, there are some harmful factors such as industrial noise, high temperature, dust, radiation, etc. in the production operation environment and construction work site. These toxic and harmful factors will cause acute poisoning accidents, and with time, even at low concentrations (doses), they will affect the health of workers and cause various occupational diseases due to their combined effects.
Program overview
The deadly threat in this industry lies in the leakage and combustion of explosive gases, and dangerous gases are always accompanied by the entire operation process of production and processing. Use multiple Gas Detectors to conduct real-time and on-site monitoring of enterprises and parks, install flammable and toxic Gas Detectors in hidden gas leakage areas, personnel work areas and gas storage areas, and cooperate with alarm control cabinets, background data analysis, and data processing centers , can better realize comprehensive monitoring, display and early warning in the monitoring area, thereby reducing fire and explosion accidents, avoiding casualties, and ensuring the property safety of enterprises and parks.
1. On-site gas monitoring solution
The Detector can continuously monitor the measurable gas in the industrial environment, and convert the gas concentration into a digital signal, which is transmitted to the gas alarm controller, which is identified, displayed and processed by the controller. When the index of a certain gas to be tested on site exceeds or falls below the set standard, the controller system will automatically perform a series of alarm actions, such as alarm, exhaust, trip, etc. (varies according to different settings of the user).
2. Data transmission scheme
YC-G data remote transmission terminal is a new type of terminal equipment for collecting sensor data with high flexibility and high reliability that our company has carefully researched and developed on the basis of summarizing the design and production experience of many years of data collection equipment. .
The device can be widely used in fixed Gas Detectors and gas control cabinets supporting the modbus protocol. Real-time monitoring of on-site gas concentration, real-time collection and transmission of various data. Through the 485 communication line and the detection equipment connection, the concentration value, decimal point, unit, equipment status and other information can be read in real time, and uploaded to the company's data monitoring server center according to the set time interval.
3. Terminal system solution
Baoshian industrial gas online monitoring platform uses new technologies such as the Internet of Things, cloud technology, big data, and mobile Internet as means to realize real-time gas data reporting, remote control, and equipment management, so as to realize the detection of dangerous gas leakage in the monitoring area. Event monitoring and prompting and alarming can effectively prevent the occurrence of dangerous accidents in enterprises, realize gas leakage and management in the production process, and ensure safe production of enterprises.
Managers can check the real-time values of monitoring area parameters at any time through computers, mobile phones, tablets, etc. When the relevant parameters exceed the limit, an alarm message will be issued to remind the manager to take corresponding measures, and control instructions can be sent to the relevant equipment through the computer or smart phone to realize the remote control of the gas parameters in the monitoring area.
System Features
1. Comprehensive remote monitoring of changes in flammable and explosive gas content in the factory area;
2. Predict the trend of change;
3. Realize safe production and achieve sustainable business growth.
