The pore filters for petrochemical feed oils achieve good cleaning results using chemical cleaning and high-pressure water jet technology
Thread Content
Some crude oils used in petrochemical plants contain particulate impurities, and filters with pore sizes of around 20 microns are generally used to remove these impurities. After being used for a period of time, the filter becomes clogged, indicating that it has failed. Using industry-standard sintering and chemical cleaning methods is costly, first and foremost ； Second, the number of cleaning cycles is limited (filter failure). This increases production costs. Chemical cleaning combined with high-pressure water jet technology yields good results, reduces costs, and there is no limit to the number of cleaning cycles. The following figure shows the cleaning process:
In petrochemical plants, filters with a size of around 20 microns are often used to remove particulate impurities when filtering crude oil. Although traditional sintering and chemical cleaning methods can address the clogging issue of these filters, they are costly and have limited numbers of cleaning cycles. In contrast, chemical cleaning combined with high-pressure water jet technology not only provides excellent cleaning results, but also significantly reduces costs; moreover, there is no limit to the number of cleaning cycles, which effectively extends the service life of the filters and lowers production costs. .
First, purge with steam, then perform chemical cleaning (or ultrasonic cleaning). The cost is lower then.
