Electricity with heat renovation of the oil refining process with the heat pipeline system

Energy -saving and consumption reduction is the only way to survive and develop oil refining enterprises. However, comprehensive energy consumption of some petrochemical companies is still high. Among them, the process pipeline of the oil refining system is accompanied by thermal heating, the temperature of the storage and transportation facilities, and the heating of the device. It is still an important reason to consume a large amount of high -temperature steam. Although the steam accompanying pipeline is low in installation, it costs a lot in later maintenance. With the popularization of electricity with electricity, more and more petrochemical companies use electricity with electricity to replace steam accompaniment.

Taking a petrochemical of Lanzhou as an example, in addition to the new DN600mm trunk, the company has been put into use in the early days of the establishment of the factory. The materials are aging and the strength performance has been reduced. , Can only maintain the status quo and often leak. Previously, the operation could only be "headache medical head, foot pain to treat feet", where to deal with, so that there are many hidden dangers and unsafe factors. In order to solve the above problems, the company communicated with us many times to explore the reliable solution of electrical accompanying heat to replace steam accompanying heat.

Petroleum and chemical materials will reduce the material temperature due to heat dissipation during long -distance conveying and long -term storage in the pipeline. Severe declines will produce the crystallization of material materials. To keep the temperature of the material from decreased, the feasible method is to give the system with heat; continuously supplement the heat to maintain the temperature of the internal material.

As a effective pipeline insulation and anti -freezing scheme, the accompanying heat has been widely used. Its working principle is to emit a certain amount of heat through the heat media, and replenish the heat loss of the accompanying pipeline through direct or indirect heat exchanges to achieve heating. Normal work requirements for insulation or anti -freezing.

Compared with the steam heat with steam, electricity has significant advantages. The following is a detailed comparison and induction:

Efficiency and energy saving:

Electricity with heat: Direct use of electrical energy to be converted into heat energy, without the need for intermediate media, so energy transmission efficiency is high and can quickly achieve the set temperature. In addition, the electricity with the heat -heat system can automatically adjust the power size according to the pipeline temperature, effectively saving electricity.

Steaming accompanying heat: Although the heat exchange efficiency can reach more than 90%, the steam is required through the pipeline, and there is a problem of energy loss and delay.

Design and installation:

Electricity with heat: simple design, convenient construction and installation, especially suitable for the heat need of complex pipelines. The tropical part of the electricity can be installed on the pipe or equipment surface by wrapping, paste or clamping, and provides a uniform heating effect.

Steaming accompanying heat: The launching steam with heat pipes requires welding. For complex pipeline layouts, construction is difficult.

Security and reliability:

Electricity with heat: High safety, no risk of steam leakage, reducing safety threats to personnel and equipment. In addition, the electricity with the heat control system also has explosion -proof, all -weather work performance, high reliability, and long service life.

Steaming accompanying heat: Although the hidden dangers such as fire and explosion are avoided, the phenomenon of "running, rusting, dripping, leakage" often occurs in steam pipelines, and there is a certain safety risk.

Environmental protection and energy saving:

Electricity with heat: It does not produce waste gas, wastewater or waste, and has no pollution to the environment. At the same time, its accurate temperature control helps improve energy utilization efficiency and avoid waste of energy.

Steaming accompanying heat: Although it is more energy -saving and environmentally friendly compared to traditional heating methods, there is still room for improvement in environmental protection and energy conservation compared to electric accompanying heat.

Economics and maintenance:

Electricity with heat: One-time investment may be slightly higher than steam accompanying heat, but at the theory of annual operating costs, usually the cost saved by the electricity of electricity can be recovered by the cost of 1-2 years. In addition, the electricity with the electricity heat system does not need to be maintained, reducing maintenance costs.

Steaming accompanying heat: Every winter, you need to spend a lot of manpower and material resources on pipeline insulation to ensure that winter operation is safe and high maintenance costs.

In summary, compared with steam accompanying heat, electricity heat has obvious advantages in terms of efficiency, design and installation, safety, environmental protection and energy saving, and economy. With the continuous advancement of technology and the increase in market demand, electric companion heat has been widely used in more fields.
