Simple and easy-to-use cleaning method for pore filters | Acid washing and passivation technique
Thread Content
It is well known in the petrochemical refining industry that a filter with a porosity of around 20 microns is used in the oil refining process. The cost of each imported filter is 9,000 yuan; nearly 300 such filters are required for one unit, which means the total cost for the filters amounts to almost 3 million yuan. However, the filter often gets clogged and needs to be cleaned. Cleaning is usually carried out by professional companies, with the cost for one unit exceeding 300,000. According to the regulations, professional cleaning can only be performed 3 times (it will become deformed if done more often). The filter needs to be cleaned once; if the process medium contains a large amount of particles, it loses its effectiveness after 2 to 3 months of use. In this way, a filter with a cost of 3 million yuan can be used for about 2 years at most. In light of this situation, the company conducted its own research on cleaning methods and adopted a combined approach of chemical cleaning and high-pressure cleaning to completely solve the problem of cleaning filters. Cleaning a filter can save more than 200,000 in cleaning costs. Moreover, this method does not damage the filter tubes, allowing for a significant increase in the number of cleanings and thus resulting in considerable savings on equipment costs.
Thank you for sharing. Wishing you all the best
In the petrochemical refining industry, the porosity of the commonly used Porex filters is around 20 microns; each filter requires approximately 300 filter elements, resulting in a total cost of around 3 million yuan. Since the filters tend to clog easily, they usually need to be cleaned by professional companies; the cost per cleaning is over 300,000 yuan, and they can only be cleaned three times. To reduce costs and extend the service life, the company has developed its own method that combines chemical cleaning with high-pressure water cleaning to clean filters. This method can significantly reduce cleaning costs, saving over 200,000 yuan per unit, without damaging the filter tubes. It also increases the number of cleaning cycles, thereby effectively cutting equipment costs. .
It won’t show an image, but I want to say that the domestic version costs 220 per piece
