Project Introduction The project is located on Huangzeshan Island, Qushan Town, Daishan County, Zhoushan City, Zhejiang Province, with a total construction area of approximately 180000 square meters and a total tank capacity of 1.04 million cubic meters. It is a key project for the development and construction of the international oil storage and transportation base in the Zhejiang Free Trade Zone. It is backed by the "artery" of the Yangshan International Waterway and can connect various regions of East China and the Yangtze River Basin, as well as major ports in coastal cities in China. It is recognized as a natural port for oil transfer and storage in the industry. After the completion of the project, it is of great significance to enhance the capacity of crude oil unloading and storage facilities from Ningbo to Zhoushan Port, promote the construction of the Zhoushan Islands New Area, improve the architecture of the Zhoushan oil shipping system, and enhance the international oil storage and transportation capacity of Zhoushan. The project is one of the important projects in promoting the construction of international oil and gas storage and transportation bases in Zhoushan City, Zhejiang Province, and is also the main oil storage project in the northern area of Zhoushan. The total investment of the project is 1.256 billion yuan, mainly constructing a total of 1.04 million cubic meters of crude oil and fuel tanks, including 6 100000 cubic meters of crude oil tanks, 6 50000 cubic meters, 2 40000 cubic meters, and 2 30000 cubic meters of oil tanks. Heat tracing device: crude dye oil, asphalt, and waste oil pipelines Crude oil is a complex mixture containing hydrocarbons and other chemical substances such as paraffin, cycloalkanes, asphaltenes, and resins. In the process of crude oil production and transportation, problems related to pipeline systems are mainly caused by high molecular weight paraffin and asphaltene. At high temperatures, paraffin molecules dissolve in crude oil. If transported through pipelines, the temperature of the crude oil drops below the wax precipitation point, which is higher than the flow point. The decrease in paraffin solubility causes paraffin molecules to precipitate and crystallize from the crude oil, thereby affecting pipeline flow. For this reason, we need to install insulation measures such as electric heat tracing to maintain the temperature required for crude oil pipeline transportation. Due to the different pipeline areas that require heat tracing in the second phase tank farm of the Huangzeshan Oil Transfer Storage and Transportation Project, our Anhui Huanrui technical personnel have selected corresponding electric heat tracing product models for different heat tracing pipelines. The series constant power RDC1Q-J3-20-220 and low-temperature enhanced DBR-25-220-PB are about 110000 meters of electric heat tracing, effectively solving the problem of crude oil precipitation and crystallization in the pipeline an...

Going out for vacation has become a way of people's leisure, and commercial hotels and homestays have become places where people go out to live. Compared with cookie-cutter, standardized decoration, and commercialized hotels, homestays pay more attention to taste and have more diverse designs. They are not only beautiful and comfortable, but also have their own stories, which are loved by many young people. But B&Bs are generally selected on the edge of mountains, rivers, lakes and seas, with beautiful scenery and fresh air. But in winter, the temperature of remote homestays is lower and the weather is cold, and people's desire to travel will be relatively reduced. These homestays often encounter the curse of "coldness" in winter. Imagine that when tourists stay in a B&B hotel in winter, they can meditate on the floor with bare feet, soak in the hot springs and watch the stars. Do you need to worry about the occupancy rate? Which heating method is more suitable for this homestay? Many homestays and hotels first think of installing central air conditioners in terms of heating methods. Although it is easy to control, convenient and flexible, the heating of air conditioners is air convection heat dissipation, and the comfort is relatively poor. Feet never get warm. In addition, the auxiliary heating function may be required for air-conditioning heating in mountainous areas where the temperature is too low, thereby increasing the operating cost of the hotel. In addition, since homestays are generally built in areas near mountains and rivers, infrastructure such as pipeline gas may not be perfect, and wall-hung boilers using gas heating are also limited. Therefore, the more recommended homestay heating solution is the Huanrui intelligent electric floor heating solution with electric heating.

As a warm, comfortable and healthy heating method, not only luxury villas like it, but also more and more ordinary houses will consider adding it to the decoration list. Even B&B hotels have turned their attention to heating cable electric floor heating. There are different opinions about the origin of "homestay". In mainland China, there are many types of homestays, which cannot be fully summarized by a unified standard, but each type includes the general characteristics of homestays. Homestays mainly refer to the use of free rooms in self-use residences, combined with local humanities, natural landscapes, ecology, environmental resources and agricultural, forestry, fishery, and animal husbandry production activities to provide personalized accommodation for travelers who go out for outings or long trips.

PetroChina Karamay Petrochemical Company is located in Jinlong Town, Karamay City, Karamay District, Uygur Autonomous Region. The white oil hydrogenation unit is currently one of the few domestic devices that use more advanced hydrogenation methods to produce white oil products. It produces a variety of specifications. White oil is widely used in industry, cosmetics, food, medicine and other fields. The white oil products of various brands and grades produced by Karamay Petrochemical Company have been popular in the domestic market, with high reputation and popularity and considerable economic benefits. In response to the various needs of the heat tracing project of this device, Anhui Huanrui provided a complete set of electric heat tracing solutions. Project difficulties 1.The reaction temperature changes greatly, and the catalyst activity is easily affected. The white oil high-pressure hydrogenation unit is a high-temperature, high-pressure hydrogenation catalytic process. After the raw materials, catalysts, and pressure are determined, temperature is the main factor affecting desulfurization, denitrification and conversion rate, and it is also the main means to control the reaction depth. For the first-stage reaction, appropriately increasing the reaction temperature can increase the desulfurization and ammonia removal rate, reduce the pollution and poisoning of the second-stage catalyst, and create conditions for the second-stage reaction. However, the reaction temperature is too high, especially when the bed temperature is too high, on the one hand, the cracking reaction of the reactants is increased, so that the low boiling point components increase, and the yield decreases; on the other hand, the bed layer is caused to accumulate coke and the pressure drop increases. The catalyst life is reduced. Therefore, during the production process, the reaction temperature needs to be kept within an appropriate range, and stable and continuous. 2. The pipeline has steam purging requirements, the highest temperature can reach 200 ℃ Steam purging is suitable for conveying power steam pipelines or thermal pipelines, purging with large flow of steam, and the flow rate is not less than 30m/s. Press steam-slowly raise the warm tube-constant temperature for 1h-purge-stop the air to cool down-reheat the pipe to increase the temperature, constant temperature, the second purge, and this repetition is generally no less than 3 times. Under long-term high temperature conditions, the electric heating cable needs to ensure normal and stable operation under high temperature conditions, and must withstand a temperature of 200°C. Solution In order to further confirm whether the electric heating cable can meet the reaction temperature. Before the installation, the company's engineering department cooperated with the main business unit to conduct field tests on the heat tracing performance. The heat tracing has a fast heating speed, high temperature resistance, temperat...
