The manufacturing method
of n-butane
n-butane is a common chemical raw material, widely used in fuel, solvent, refrigerant and other fields. This paper will introduce the manufacturing method of n-butane, including raw material selection, reaction principle, process flow, equipment selection and so on.

1. Feedstock Selection

n-Butane Manufacturing Feedstock is primarily the butane component of natural gas or naphtha. Among them, the butane content in natural gas is higher, generally more than 10%, while the butane content in naphtha is lower, which needs to be obtained by separation and purification.

2. reaction principle

the manufacture of n-butane is mainly through the method of separation and purification, the butane component in the raw material is separated. Common separation methods are distillation, adsorption, membrane separation and so on. Among them, distillation is the most commonly used method, through heating and condensation, the different components in the raw material are separated according to the boiling point.

3. Process
The manufacturing process of
n-butane mainly includes the following steps:

1. Raw material pretreatment: the raw material for desulfurization, dehydration and other pretreatment to ensure the smooth progress of the subsequent separation process.

2. Separation and purification: the use of distillation and other methods, the raw material in the butane component is separated, to obtain a higher purity of n-butane products.

3. Product post-treatment: the n-butane product is subjected to post-treatment such as desulfurization and dehydration to ensure the quality and safety of the product.

4. equipment selection

In the manufacturing process of n-butane, the equipment that needs to be used includes heating furnace, rectifying tower, condenser, pump, etc. In the selection of equipment, need to consider the following factors:
1
equipment production capacity and process requirements.

2. The equipment has reliability and stability, which can ensure long-term stable operation.

3. The equipment has lower energy consumption and maintenance costs, which can improve production efficiency and economic benefits.
Precautions for manufacturing
5.

In the manufacturing process of n-butane, the following matters need to be paid attention to:

1. Strictly control the quality and purity of raw materials to ensure product quality and safety.

2. Strengthen equipment maintenance and maintenance, conduct regular inspections and repairs to ensure the normal operation and service life of the equipment.

3. Strengthen the safety management in the production process, comply with relevant regulations and standards, and ensure the safety and reliability of the production process.

In short, the manufacturing method of n-butane needs to be comprehensively considered according to factors such as raw materials, process requirements, and equipment selection to ensure product quality and economic benefits. At the same time, it is necessary to strengthen management and control in the production process to ensure the safety and reliability of production.
