[Chemical Knowledge]：Considerations for Improving the Sampling Efficiency of Hydrogenation Kettle

Read： 1001 Time：8months ago Source：Transform the World with Simplicity

In the petrochemical industry, the hydrotreater is a common equipment used for the reaction and product separation in the hydrocracking process. In the operation of the hydrogenation kettle, sampling is a very important link, which directly affects the quality of the product and production efficiency. In order to improve the sampling efficiency, the following are the matters needing attention in the sampling process of the hydrogenation kettle.

ensure that the sampling tool is clean. Before sampling, make sure that the sampling tools (such as sampling bottles, pipes, etc.) are clean and free of any impurities or contaminants. Otherwise, these impurities or contaminants can affect the accuracy of sampling and the quality of the product.

pay attention to the selection of sampling position. In the hydrogenation kettle, the product composition at different positions may be different, so it is necessary to select the appropriate position according to the specific situation when sampling, so as to ensure that the sample obtained can represent the product of the whole hydrogenation kettle. In addition, attention should be paid to the mastery of sampling time. During the operation of the hydrotreater, the composition of the product may change over time, so it is necessary to sample at the right time to obtain accurate product information.

pay attention to safety precautions. Personal protective equipment should be worn during sampling to ensure the safety of the operator. At the same time, it is necessary to pay attention to the temperature, pressure and other parameters inside the hydrogenation kettle to ensure that the sampling process will not cause damage to the equipment and operators.

timely processing of sampling samples. After sampling, the sample needs to be sent to the laboratory for analysis in time to obtain detailed information about the product. At the same time, the sampling tools should be cleaned in time for the next use. To sum up, there are many matters needing attention in the sampling process of hydrogenation kettle, and each link affects the accuracy and efficiency of sampling. Only by strictly following the operating procedures can the sampling process of the hydrogenation kettle be carried out smoothly, thereby improving product quality and production efficiency.
