In the solvent deasphalting unit of the Henan refinery, the process environments are mainly colloids, road asphalt, waste oil, and catalytic cracking oil slurry, which are high freezing temperature environments, and the service temperature provided by the technologist is 180-250 °C. ° C.

Electric heating is commonly used to maintain the temperature. Conventional electric heating methods include jacketed pipe heating, cement heat external heater, electric heating, steam heating, etc. D. After many comparisons in terms of labor and cost savings, the company finally opted for electric heating.
The reinforced heating cable we supply can maintain a maximum temperature of 600 °C and withstand a maximum temperature of 800 °C, which can be used for high temperature heating where the steam heater is not suitable.
In a certain range, electric heating has the following advantages over traditional steam heating and water heating:
The electric heating device is simple, heats evenly, adjusts the temperature precisely and quickly, can be remotely controlled and remotely controlled to realize automatic control.
The electric heating has explosion-proof, all-weather performance, high reliability and long service life.
The electric heating has no leaks, which is good for environmental protection, does not cause "work, cotton, drip or leak" and does not pollute the environment.
Electric heating saves steel. Electric heating products have small dimensions and do not increase the amount of insulating materials used in laying, which saves insulating materials.
Electric heating saves water resources, which is more advantageous in areas with water scarcity or poor water quality.
The amount of work on electric heating is small, which can significantly reduce the costs of design, construction and operation.
Electric heating is not only suitable for various places where steam and hot water are heated, but it can also solve problems that are difficult to solve with steam and hot water heating.
The biggest advantage of electric heating products is high efficiency, which allows you to significantly save energy.
The electric heating cable has a small size and a small heat dissipation surface.
The efficiency of heat exchange of electric heating reaches 90%-96%.
The electric heating heat sink is uniform, and it only needs to compensate for the heat loss with an insulating layer.
Power transmission losses are very small.
The electric heating can be strictly monitored by the temperature control system and automatically shut down and supply power to meet the requirement that the electrical heat generated or heat transferred be exactly equal to that of the pipeline.

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.
