The ACR filter represents a unique and advanced technology that has been successfully demonstrated across various commercial operations. It utilizes a proprietary wire mesh as the filtering medium.
A notable characteristic of ACR technology is the rotating shaft within the filtering element, which significantly reduces wash oil consumption during the automatic backwash phase, thereby considerably lowering operating costs. The shaft also guarantees high backwash efficiency and enables the filtration process to continue uninterrupted during the backwash phase.
The high efficiency of the backwash process is crucial for the superior performance of the ACR filter. This parameter is easily measured by monitoring the pressure drop between the filter inlet and outlet after each backwash cycle. In all operating ACR filters, the pressure drop remains constant and close to zero, confirming that no cake accumulates on the filtering element over time.
The absence of significant cake formation on the wire mesh allows the ACR filter to operate at a low pressure drop, approximately 0.5 bar (7.0 psi). This prevents the agglomeration of contaminants and asphaltenes, ensuring consistent and efficient filtration.
The ACR filter is designed to accommodate large variations in solids content. Due to the short backwash time (approximately 10 seconds), the filter can easily handle a sudden increase in solids content by simply adjusting the frequency of backwash cycles.
The remarkably low consumption of wash oil, which is less than 1% of the feed to the filter, results in substantial savings in operating costs. This efficiency allows for a return on investment within 6-10 months. The ACR technology is capable of filtering even the heaviest and most viscous fluids at an absolute filtration degree of up to 4 microns, ensuring 100% removal efficiency of particles larger than the specified filtration degree.
The ACR filter requires no ordinary maintenance, with a lifespan of over 3-5 years without scheduled maintenance. The reduction in operating and maintenance costs, along with a 60-80% reduction in the number of valves, eliminates the need for a dedicated PLC system.
The ACR filter’s smaller plot area, 50% less than conventional filters, makes it adaptable to various footprints and easily integrable into existing filtration systems through retrofitting.
Depending on plant availability or process conditions, the ACR filters are available in both internal and external backwashing configurations. In the internal backwashing system, the cleaning phase is performed using the filtered feed (which retains the physical properties of the feed), while in the external backwash configuration, an external fluid is used for the cleaning phase.
