Oil Sludge Pipeline Electric Heating System at Oil Refinery

In the past, most refineries have used water or steam heating pipes, but due to the shortcomings of the two heating methods in recent years, electric heating has become the main direction of heating pipelines. How is the oil slurry pipeline heated and insulated like a conventional pipeline at a refinery?

The electric heating system of the pipeline mainly consists of two parallel channels and a semi-conductive plastic belt, which can be automatically adjusted after the beam treatment. Its texture is rigid, flat and soft, and it will not change for a long time.

The oil sludge contains a catalyst, so it is difficult to transport through a pipeline. Thus, with the exception of the oil sludge circulation pipeline at the bottom of the fractionation column, which has a high temperature and cannot be stopped during normal production, heating is not required, and other oil sludge pipelines need heating. These include:

After cooling, the oil sludge line is ejected.

If the sludge stripping column installed in the device cannot operate normally in continuous mode, the sludge pipelines associated with the tower must be heated. In particular, electric heating should be provided for the circulation line or auxiliary line used in the conversion operation. In recent years, some units of the catalytic processing line on fuel oil often change the amount of oil pulp emitted as a means of adjusting the operation. In order for the pipeline to be smoothly used in a variety of operating conditions, it is useful to have a heating pipeline.

All devices are equipped with special emergency oil coolers for emergency situations, and the inlet and outlet pipes must be equipped with heating wires.

The heavy dirty oil released at the start-up and stop of the device is cooled by the oil sludge cooler and then sent to the tank area. This section of the pipeline must be provided with electric heating.

Although the temperature of the refinery sludge pipeline is high, its flow rate is low and inconsistent, so heating needs to be considered.

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.

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.

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.

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 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.
