Application Area

The petroleum industry refers to the chemical industry that uses oil and natural gas as raw materials. The range is very wide and there are many products. The crude oil is subjected to cracking, reforming and separation to provide basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene. From these basic raw materials, various basic organic raw materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be obtained.

Natural gas refers to all-natural gases naturally occurring in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed methane, and bio-generated gas).

The chemical industry is the general term for enterprises and units engaged in the production and development of the chemical industry. The penetration of various aspects of the chemical industry is an indispensable part of the national economy. Its development is an important practical significance for the economic and social development of human beings.

The power industry converts primary energy such as coal, oil, natural gas, nuclear fuel, hydropower, ocean energy, wind energy, solar energy, and biomass energy into electrical energy through power generation facilities, and then supplies users as an energy industry through transmission, transformation, and distribution systems. department.

Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields, and more and more into the daily lives of ordinary people.

The paper industry is an industrial sector that manufactures a variety of paper and board. It includes pulp manufacturing for pulp production from wood, reed, bagasse, straw, wheat straw, cotton straw, hemp, cotton, etc., manufacturing paper and board industry, and processing, glazing, gluing, lamination, etc. Paper and font paper processing paper manufacturing in several aspects.

Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore. For high purity Al2O3, it is generally prepared by chemical methods. Al2O3 has many isomorphous crystals, and there are currently more than 10 kinds of crystals, mainly three kinds of crystal forms, namely α-Al2O3, β-Al2O3, and γ-Al2O3. Among them, the structure has different properties, and is almost completely converted into α-Al2O3 at a high temperature of 1300 ° C or higher.

Mining refers to the extraction of naturally occurring minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). This includes activities such as underground or above-ground mining, operation of mines, and all auxiliary work, such as grinding, beneficiation and treatment, that are generally carried out near the mine site or site to process raw materials. It also includes the preparations needed to get the ingredients sold.
