The chemical industry plays an important role in the national economy of many countries and is a fundamental and pillar industry. The development speed and scale of the chemical industry have a direct impact on various sectors of the social economy. The annual output value of chemical products in the world has exceeded 15000

The petroleum industry is divided into upstream, midstream, and downstream, and the relationship between the upstream and downstream industrial chains is very close, with a very distinct industrial chain structure and industrial chain information transmission effect. Among them, the upstream business includes exploration and development of crude oil and natural gas, while the midstream

The power plant industry is a factory that converts various primary energy sources in nature into electrical energy (secondary energy). At the end of the 19th century, with the increasing demand for electricity, people began to propose the idea of establishing power production centers. The development of motor manufacturing technology and the application of electrical energy

Natural gas is stored in underground porous rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogenic gas, with a small amount also occurring in coal seams. It is a high-quality fuel and chemical raw material. The main use of natural gas is as fuel, which can be used to produce carbon black.

The metallurgical industry refers to the industrial sector that mines, selects, and sinter metal ores, and then refines and processes them into metallic materials. Divided into: (1) Black metallurgy industry, which refers to the industrial sector that produces iron, chromium, manganese and their alloys, mainly for modern industry and transportation..

The production department of chemical drugs consists of two parts: raw material drug production and drug formulation production. Raw materials are the material basis for drug production, but they must be processed into drug formulations suitable for use in order to become drugs. In China, the pharmaceutical industry also includes traditional...

The purpose of the water conservancy industry is to comprehensively consider and reasonably arrange the control, development, and use of surface and groundwater resources, in order to achieve maximum safety, economy, and efficiency.

The main media encountered by the paper industry in production include slurry, steam, water, sewage, and black liquor. Among these media, except for the slurry in the bleaching section containing a small amount of chloride ions and the black liquor in the washing and alkali recovery departments containing alkali, other media are less corrosive

In the desulfurization system, consideration should be given to adapting to temperature, corrosiveness, and sealing leakage standards. Commonly used ones include butterfly valves, ball valves, and gate valves. The material conveying system will use pneumatic knife gate valves, insert plate valves, powder specific butterfly valves, V-shaped ball valves, ceramic valves, spiral.
