Electric heating of filters of main pipelines at oil filling stations
Adding electric heating to the oil mixing line at room temperature can solve the problem of clogging the filter well and facilitate cleaning.

With the rapid development of my country's economy, the demand for crude oil is increasing. Adding a certain proportion of light crude oil to high viscosity crude oil with poor fluidity can improve the fluidity of crude oil to a certain extent. Pipeline transportation is a method of transporting crude oil through the pipeline, which saves energy and reduces consumption. However, mixed crude oil has a complex rheology. If the pipeline is mixed with heavy oil at room temperature and the oil sources are varied, a large amount of colloidal impurities will be formed in the process of oil transportation, especially after the scraper filter has been sent, whose freezing temperature is much higher than the outside air temperature, making it difficult to clean the filter. Thus, adding electric heating to the oil mixing line at room temperature can solve the problem of clogging the filter well and facilitate cleaning.

This article takes as an example the installation of an electric heating oil station filter at the Shengli oil field to discuss the effect of adding electric heating of the pipeline to the normal temperature main pipeline filter.

Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Which electric heating should be chosen for the main pipeline transport of heavy oil
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.

According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
