Detachment leaders conduct investigation and guidance on fine chemical companies in their jurisdiction

Below, the hazards of the six most common types of high-risk production devices are introduced. 1 Nitration reaction There are two types: One refers to the reaction of introducing nitro groups to replace hydrogen atoms in the molecules of organic compounds to generate nitro compounds, such as the nitration of benzene to produce nitrophenylglycerin, and the nitration of nitroglycerin to produce nitroglycerin; the other is to replace the hydroxyl group in organic compounds by nitrate. The chemical reaction of nitrate esters. Most of the reactions in the production of dyes and pharmaceutical intermediates are nitration reactions.

How do petrochemical companies digitally transform? This company has provided a successful demonstration!

The high-risk process production equipment of chemical enterprises mainly refers to the chemical reaction process including nitrification, sulfonation, halogenation, strong oxidation, diazotization, hydrogenation, and extremes such as high temperature (≥300℃), high pressure (≥10MPa) and deep cold (≤-29 ℃). Operating conditions of the production plant. High-risk storage devices mainly refer to storage devices for dangerous chemicals such as highly toxic liquefied hydrocarbon liquid ammonia, low flash point (≤-18 ℃), flammable liquid liquefied gas.

Research on Human Resource Management Issues in the Chemical Industry

Due to the development background of the chemical industry, historical changes, the particularity of the working environment, the imperfect internal management system of the organization under the planned economy, the market competition of the industrial chain, the talent attraction of foreign-funded enterprises and the reasons of the practitioners, it is sustainable for the construction of the enterprise and the industry. Development brings impacts and challenges. The transformation and upgrading of the chemical industry is of far-reaching significance to the development of my country's national strategy, and the improvement of human resource management in chemical companies plays an irreplaceable role in the upgrading and development of the chemical industry.

"The pillars" can withstand, the chemical industry is steadily competing for high-end

Chemical industry is the basic and pillar industry of the national economy, and most developed economies in the world have strong chemical industries. However, as the country's largest chemical province, there are many hidden dangers in safety and environmental protection, and structural excess pressure... This "pillar" industry was once considered a typical representative of Shandong's heavy economic structure and low development quality. Shandong has learned from the painful experience, grasping strong medicine to eliminate malaria, and promoting quality and efficiency with the other hand, and launching a tough battle for transformation and upgrading in the chemical industry. In 2021, the construction of the new and old kinetic energy conversion comprehensive experimental zone enters the fourth year, and Shandong Chemical Industry is still firmly in the top position in the country. The top spot, but different from relying on total indicators in the past, the industry development now shows solid confidence and strength: in the first half of the year, the industry-wide profit rate reached 7.5%, which was nearly doubled from last year's 4.3%. "In the past few years, Shandong has vigorously implemented the comprehensive rectification of the chemical industry, while actively promoting green, smart, and high-end development, and has embarked on a path of high-quality development of the chemical industry with Shandong characteristics." China Petroleum and Chemical Industry Association Chang Li Shousheng commented.

Green hydrogen will become the "winner" for chemical companies to break through the bottleneck of growth. These companies are ahead of schedule.

Before the holiday, the price of ethylene oxide was raised by 300 yuan/ton as expected by the market. The main driving force for the increase came from the shutdown of multiple ethylene oxide installations in May. A good supply-side pattern provides favorable support for the market operation mentality. Merchants are actively improving when entering the market, and new orders in the downstream market are supported, and raw materials just need to be followed up as normal.
