7/3, equilibrium residual fluid cracking catalyst), S (elemen - tal sulphur), and activated carbon. These DM materials were tested as model compounds since solid particles in the reactor feed streams in refinery or petrochemical plants mostly contain carbon residuals, dirt (silica sand), catalyst fines, sulphur, FeS, FeO, and Fe2O3. Experiment 2 In the second experiment, liquid phase test - ing was conducted at atmospheric pressure and room temperature. For each test, approximately 50g of preci - sion-weighed solvent was mixed with 1.0g of precision- weighed DM powders in a precision-weighed vessel. Then, various amounts of FM powders (Fe2O3) were added to the mixture separately. A permanent MB, with magnetic power of 6,150 GS, was then dipped into the solution to stir it up, allowing the suspended solid powders to be attracted by the MB. After attraction, the MB was taken out of the solution, and the vessel with the solution containing the residual powders was weighed again. Weight percent of mixed powders attracted by the MB was calculated and summarised in Table 7 . Table 7 shows the results where water was used as the solvent, RFCC powders (equilibrium residual fluid cracking catalyst (SiO2/Al2O3: 7/3)) as the DM substance, and Fe2O3 (FM) powders as the magnetic inducing agent. Approximately 0.1g and 0.3g of Fe2O3 were added separately to the solu - tion for testing, and the results showed 90-92% of the mixed powders can be attracted by the MB, depending on the amount of Fe2O3 added. The amount of powder attracted by the MB was proportional to the amount of Fe2O3 added to the mixture, although the effect of adding more than 0.1g of FM (10% of DM) was quite limited. Commercial data from light coal tar liquid previously demonstrated that the Universal Filter could remove 97.6% solid particles from liq - uid streams (higher than the lab demonstration). Conclusions Universal Filter technology has demonstrated the following capabilities: • Simultaneous removal of FM, paramagnetic, and DM solid particles from liquid process streams. • Removal of all sizes of solid particles, including nanometer (7 nm and larger) size particles, from the process stream. • Extremely effective at keeping extractive solvent in extraction processes solid-free (down to nanometer par - ticles) with purity as high as 99.9% to maximise solvent performance. • Providing enhanced operation in combination with the conventional cartridge filter to achieve near-total solid par - ticles removal. The combination also keeps the cartridge cleaner, protecting it from more frequent replacements with much-reduced downtime. • No spendable materials, such as filter screens or reticulated top-bed packing materials, are needed to lower the costs. • No energy, pump, heat exchanger, or other auxiliary equipment is needed. • Significantly longer operating cycle to lower process costs (can be adjusted by filter design). • Up to 300ºC operating temperature at any pressure.

• Filter backflush and cleaning are infrequent and normally take 30-60 minutes to minimise exposure to air (oxygen). • Filter design to handle total circulation in the subject unit. • Non-exposure, sealed filter design is available for haz - ardous operations and eliminating exposure to air (oxygen). • Filter technology is protected by numerous US and for - eign patents.
