The nature and use
of unconventional natural gas in the field of chemical production
Abstract

unconventional natural gas is an important chemical production raw material, with unique properties and a wide range of uses. In this paper, the nature, classification, production, transportation and application of unconventional natural gas in chemical production are discussed in detail. Through the research of this paper, the purpose is to deepen the understanding of the importance of unconventional natural gas in the field of chemical production raw materials, and provide valuable reference for the production and research in related fields.

1. Introduction

With the rapid development of the chemical industry, unconventional natural gas, as an important raw material for chemical production, has attracted more and more attention. Unconventional natural gas not only has abundant reserves, but also its unique properties make it widely used in chemical production. This paper will discuss the nature and use of unconventional natural gas in detail, in order to provide valuable reference for chemical production.

2. the nature of unconventional natural gas

Unconventional natural gas refers to those natural gas resources that are not easily extracted by traditional methods, mainly including shale gas, coalbed methane, tight sandstone gas and so on. These unconventional natural gas resources usually have abundant reserves, but due to the limitation of geological conditions, the exploitation is difficult. The main component of unconventional natural gas is methane, but also contains a small amount of ethane, propane, butane and other hydrocarbon gases and non-hydrocarbon gases.

3. classification of unconventional natural gas

unconventional natural gas can be divided into the following categories according to its origin and geological conditions:

1. Shale gas: Shale gas refers to natural gas resources contained in shale layers. Due to the low permeability of shale layers, the exploitation of shale gas requires the use of horizontal drilling and hydraulic fracturing techniques.

2. CBM: CBM refers to natural gas resources generated and stored in coal seams. The main component of coal-bed methane is methane, and contains a small amount of carbon dioxide and nitrogen.

3. tight sandstone gas: tight sandstone gas refers to natural gas resources stored in tight sandstone layers. Due to the compactness of sandstone layer, it is difficult to exploit tight sandstone gas.

4. the production and transportation of unconventional natural gas

The production and transportation of unconventional natural gas is a complex process that requires the use of advanced technology and equipment. On the production side, techniques such as horizontal drilling and hydraulic fracturing are often used to extract unconventional gas. In terms of transportation, natural gas is usually transported by pipeline to the place of consumption. At the same time, in order to ensure the safe transportation of natural gas, strict maintenance and management of pipelines are required.

5. the application of unconventional natural gas in the production of chemical products

unconventional natural gas in the production of chemical products has a wide range of uses, mainly used in the following aspects:

1. as chemical raw materials: unconventional natural gas can be used as chemical raw materials, for the production of methanol, ethylene, propylene and other basic chemicals. These basic chemicals can further produce various derivatives, which are widely used in plastics, fibers, rubber and other fields.

2. As fuel: Unconventional natural gas can be used as fuel for power generation, heating and other fields. Compared with traditional fuels such as coal and oil, unconventional natural gas has the advantage of being clean and environmentally friendly.

3. as a syngas feedstock: unconventional natural gas can react with oxygen or steam to generate syngas (a mixture of CO and H2), which is further used to produce synthetic ammonia, urea and other chemical products.

6. conclusion

unconventional natural gas as an important raw material for chemical production has unique properties and a wide range of uses. With the continuous progress of technology and the improvement of environmental protection requirements, the application of unconventional natural gas in chemical production will be more extensive. Therefore, it is of great significance to strengthen the research and development of unconventional natural gas, which can provide strong support for the sustainable development of the chemical industry.
