Refining processes, whether hydrocracking, catalytic cracking, catalytic reforming or others, put reciprocating compressor run times at a premium.
Cook Compression applies its long expertise, advanced technologies and performance analytics to provide highly engineered solutions that prevent unscheduled downtime and extend mean time before overhaul.
Valves Optimized for Dirty Service
Debris and high pressures in refining can challenge valve reliability and performance, and lead to leakage. Cook Compression has developed two valve styles ideal for these operating conditions, and custom engineers the valves to each application.
The Manley® compressor valve is the world-standard for radiused-disc valves, with thousands running in hydrogen and hydrogen-rich compressors at refineries. Foreign debris in the gas passes through the Manley valve with minimal impact, while the valve’s thermoplastic discs conform closely to the valve seat for a highly effective seal. The valve body, springs and bolts are constructed from carefully selected alloys that exhibit high resistance to corrosion.
The MOPPET® valve also offers a rugged construction for reliability in refining processes. MOPPET valve flow paths are designed to accommodate dirty flow; each valve element is designed for damage resistance; and, for flare gas applications, materials are selected to handle the challenges of corrosion. Optional elastomer-enhanced seal elements can flex and conform to valve seats that are damaged or worn, retaining a gas-tight seal and protecting the seat surface itself. In a field test of an elastomer-enhanced MOPPET on a hydrogen compressor with chronic valve problems, an analyzer revealed no indications of leakage even after months of continuous service.
Gas Flow Measurement
Sentrix™ flow measurement technology provides a convenient, cost-effective solution for refineries to measure leakage from packing case vent flow and meet US EPA Greenhouse Gas Reporting Rules. Sentrix inline meters are calibrated for a specific gas composition, with calibrations available for most gases, including hydrogen, methane and carbon dioxide. Sentrix portable meters are provided with six field-selectable factory gas calibrations.
Cook Compression can also provide system upgrades and technical support to help refineries meet emissions requirements.
