Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of petrochemical raw material sampling devices, specifically a convenient petrochemical raw material sampling device. Background Technology
[0002] Petrochemical feedstocks mainly include basic resources such as crude oil, natural gas, and refinery gas, as well as key intermediates derived from them, such as naphtha, ethylene, propylene, and aromatics. Crude oil is distilled to separate different fractions. Light fractions, such as naphtha, are the core cracking feedstocks for the production of ethylene and propylene, while heavy fractions are converted into high-grade petrochemical feedstocks through catalytic cracking or hydrogenation processes. Sampling relies on specialized mechanical equipment to ensure accuracy and efficiency. Common equipment includes automatic pipeline samplers, rotary tank samplers, and tank truck stratification samplers. Automatic pipeline samplers are integrated into the delivery pipeline and collect the flowing medium using a piston pump or screw propeller through timed or quantitative triggering. They are suitable for continuous operation conditions such as crude oil and refined oil products. Key parameters such as pressure and temperature are recorded synchronously in real time, and the sample representativeness meets the ASTM D4177 standard. Tank sampling uses a rotary robotic arm equipped with an adjustable-depth sampling tube to extract materials at different liquid levels in the tank at multiple points in a proportional manner, avoiding compositional deviations caused by stratification. It is particularly suitable for the homogeneity testing of heavy oils or high-viscosity fluids. Value-added products: Natural gas is reformed with steam to produce syngas, which is then used to produce basic chemicals such as methanol.
[0003] Existing traditional sampling devices often use fixed positions such as flanges, which limits their use. Moreover, because petrochemical raw materials are prone to stratification, some traditional devices cannot change the sampling depth to meet more precise sampling requirements. At the same time, traditional devices generally cannot adjust the sampling volume, which may lead to waste and pollution. Utility Model Content
