Application of Wireless Steam Flow Acquisition System in Petroleum Storage Enterprises

Abstract: The application information of wireless steam flow acquisition system in petroleum storage enterprises is provided by excellent flowmeter and flowmeter manufacturers. Sinochem Xingzhong Petroleum Transshipment (Zhoushan) Co., Ltd. Xingzhong Reservoir Area In order to ensure production operations, the oil depot adopts steam tracing to maintain the temperature of oil products in storage tanks and pipelines. The steam consists of one 20t boiler and two 10t boilers. the boiler system. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the application details of wireless steam flow acquisition systems in petroleum storage enterprises. In order to ensure production operations in the Xingzhong Reservoir Area of ​​Sinochem Xingzhong Petroleum Transshipment (Zhoushan), the oil depot adopts steam tracing to maintain the oil temperature in the storage tanks and pipelines. The steam consists of one 20t boiler and two 10t boilers. system production. In recent years, the company has increased the management requirements for energy measurement in accordance with the idea of ​​lean management. In order to scientifically control the steam system and improve the steam efficiency, it is necessary to accurately measure and statistically analyze the use of steam. Previously, the steam pipe network in the reservoir area used target flowmeters to collect flow data, and then relied on manual meter reading for data summary statistics.“water hammer”The phenomenon is impacted, failures are very frequent, and the manual meter reading method is inefficient and has poor real-time performance, and the statistical analysis effect is not obvious. To this end, the reservoir area has established a steam flow acquisition system by installing a new type of steam flowmeter and using wireless transmission technology, and uploaded it to the host computer software in real time for statistical analysis and forming a report. The completion of the system provides real-time and reliable data support for the company's energy management, and at the same time realizes real-time monitoring of the steam system in the reservoir area, which is conducive to the management and control of steam usage and promotes energy conservation and consumption reduction. 1 The overall structure design of the system The steam flow acquisition system has installed a total of 52 steam flow meters in front of all thermal insulation tanks in the tank farm, the outlet of the boiler main pipe and the sub-contracting line. Using intelligent wireless technology, the data collected by the flow meters are divided into 4 areas. It is transmitted to the wireless gateway in the area, and then uploaded to the host computer, and various data are displayed through the man-machine interface. The working principle of the wireless traffic acquisition system is shown in Figure 1. 1.1 Integrated steam flowmeter Through in-depth research, 3051SFC series integrated multi-parameter orifice flowmeter was selected. The flowmeter has an accuracy of 1.25% and a range ratio of 14:1. It has the characteristics of high precision, wide range ratio and good stability. The three online variables of temperature, pressure and flow can be detected online, and the temperature, pressure and density compensation can be automatically completed in the meter head, and the mass flow and heat can be displayed, which is especially suitable for steam metering systems. Due to the integrated casting process and integrated installation, the flowmeter has high impact resistance, effectively solving the impact of steam on the equipment and water hammer problems. 1.2 Smart Wireless Adapter Each 3051SFC flow meter is equipped with a THUM775 smart wireless adapter to become a wireless node. The wireless adapter THUM (thehartupgrade module) is a microprocessor-based intelligent device and an antenna specially developed for the wired HART instrument. communicate with the wireless gateway. The wireless adapter is connected with a 4-20mA loop, and takes power from the loop, but does not have any effect on the loop. Even if the adapter fails, the loop current remains unchanged, and no battery is required. 1.3 Intelligent Wireless Gateway The wireless gateway plays an intermediate conversion role in the wireless data system. It is the link between the field instrument and the host computer, and realizes the three functions of network management, data management and equipment management.
