Gas filter

Dry seals for compressors and turbines require clean, dry gas to maintain seal integrity and ensure longevity. Gas seal support systems as specified in API-614 require filters and sometimes water-removing coalescers to ensure gas quality to the seals. For critical seal gas filtration, the ideal arrangement is to have “duplex” filters. In the duplex configuration, there is always one filter on-line filtering and/or “drying” the gas, even when the other filter element is being replaced. Dry Seal Gas Duplex Filters meeting API-614: • Reduce cost by eliminating expensive stainless steel fittings and assembly time. Compact design saves space • Simple duplex housing arrangement reduces possibility for incorrect operation and potential for shutting off the dry gas seal flow • Zero-leak integral transfer valve and double block valves provide assurance of tight shut off when replacing elements • 316 stainless steel materials • ASME code construction • Available with coalescing (liquid removal) and filter (particulate removal) cartridges • Designs to 2600 PSI

Membrane separation system

The HILCO ceramic membrane system is an ideal way to lower your oily-water waste disposal costs. The filtration system utilizes high-velocity fluid “crossflow” across the face of the membrane. The oil-free water passes through the ceramic membrane while the oily waste is concentrated in a process reservoir. Depending on the particular waste stream disposal, volumes can be reduced as much as 20x. The system is designed to accept three different micron-rated membranes (0.2 µm, 0.01 µm, and 0.005 µm) in order to meet all specific local discharge ordinances. Features and Benefits include: • High Packing Density • Broad PH Range of 2-13 • Resistant to Thermal Shock • Back Flushable • Immune to Chlorine Attack • Durable Ceramic Extends Lifetime • High Surface Area to Unit Volume • Compact Design

Oil mist eliminator

The HILCO vent mist eliminator is the answer to economically reclaiming the oily vapor found in the air stream of vents of lubrication oil systems on large, high-speed rotating equipment. These include gas turbines, turbo compressors, reciprocating engines and gearboxes. The vent mist eliminator improves safety by eliminating oily residue cause by setting oil mist on engine room floors, stairways, etc., keeps the environment clean and helps prevent exterior oil contamination of buildings and grounds. There are currently three versions available: Blower Assisted, Mist Eliminator with Heat Exchanger, and a Coalescer-Only model. All models have DM type coalescers and eliminate oil mist with an efficiency of 99.97% removal of all airborne contaminant regardless of particle size. Our vent mist eliminator collects, coalesces and filters the mist, significantly reducing visible oil plume. The captured oil is returned to the sump or crankcase, quickly and efficiently for reuse. Available in sizes and models to fit your specific application, HILCO vent mist eliminators are virtually maintenance free. Hilliard also makes HILCO-quality replacements for other brands of mist eliminators.
