OTSO Horizontal Filter Separators efficiently remove impurities from natural gas streams. Specifically designed to support high gas/low liquid flow operations, they are used upstream and downstream of compressors, in glycol dehydration units and for fuel gas applications. This uniquely configured separator comes with a single or dual boot, and one-micron filter elements that maximize the removal of dust, rust, and small particles, with the ability to handle gas capacities up to 321 MMscfd at 1400 psig. Alternative vessels contain 0.3-micron filter elements to aid in the removal of lube oil and other challenging contaminants, and can handle gas capacities up to 221 MMscfd at 1400 psig. We also have the expertise to customize a separator to meet any non-standard requirements.
