Comment PDF Separation Processes

Reduce process consumables with this new separator

By Edited by Gerald Ondrey |

Aqueous Recovery Resources, Inc. (ARR; Bedford Hill, NY; www.suparator.com), has developed the Suparator, an oil/water separation system that involves no moving parts or media, for low operational costs and minimal maintenance. The separator (diagram) is based on the Bernoulli effect, whereby increased stream velocity in a fluid results in internal pressure reduction, which enables liquids of different specific gravities to be separated. A number of valves are mounted across the fluid channel such that the major part of the flow passes underneath and a smaller portion passes overhead. Several wings are used to progressively shear off more oil and reduce water content. Dirt and other unwanted foreign objects also get removed before they settle into the water. In the first step, water and oil enter a compartment (1), from which only water gets sucked out (2). The remaining oil becomes concentrated into a thick floating layer, but still contains some water and chemicals. The oil becomes further concentrated as water and chemicals re-enter the water flow (3). Finally, the upper fraction of the floating layer gets skimmed off, isolating pure oil for refining or storage (4). This technology enables desired chemicals to stay in the aqueous…
