Wildwood LNG Demonstration Facility <br /> matter, the purpose of the coalescer is to remove possible water slugs and sand particles. Any <br /> water encountered by the coalescer will be collected in the well of the coalescer, which will be <br /> drained periodically as part of normal maintenance procedures. The particulate filter is designed <br /> to remove particles % micron or larger with 99+% efficiency. The filter will be periodically <br /> replaced during scheduled maintenance activities. <br /> Only trace amounts of CO2 have been detected in the gas. The two-bed TSA unit is used to dry <br /> the natural gas and remove CO2 from the process stream. The beds, which contain an adsorbate, <br /> are sized for a process flow rate of 600 standard cubic feet per minute (scfin) at a design pressure <br /> of 400 pounds per square inch—gauge (psig), and a design temperature of 600°F. While one bed <br /> is on-line purifying the gas, the adsorbate in the second bed is being regenerated with the process <br /> waste gas. The TSA unit includes an inline 50 kW heater that is used to heat the regeneration <br /> gas. The CO2 concentration in the TSA effluent stream determines the cycle time between <br /> processing and regeneration. <br /> The inline post filter is used to remove any adsorbate material carried from the TSA by the <br /> effluent gas stream. The filter, which contains a cartridge type filter element, protects the <br /> downstream valves and equipment from particulate material. The filter is designed with 99% <br /> efficiency for particles one n-,i.cron or larger. The filter will be periodically replaced during <br /> scheduled maintenance activi :1ec. <br /> There are no waste streams from this process system. The regeneration gas will be used in the <br /> engine-generator set as part of the fuel supply to that unit. In the event of an emergency, <br /> emergency safety relief valves may vent small quantities of natural gas to the atmosphere. These <br /> valves are designed to protect the processing vessels and piping from over pressurization. <br /> Table 3 <br /> Design Information for the Gas Purification System <br /> Equipment ss <br /> Equipment Name Preure,—(PSIG) Temperature (°F) Flow Rate <br /> Number Operating/Design,i Operafing/Desigr scfm <br /> 20-1501 Well Head Gas 350/400 Ambient/100 600 <br /> Filter <br /> 20-2101/2103 TSA Adsorber 350/400 Ambient/600 600 <br /> Bed (2) <br /> 20-1505 TSA Outlet Filter 350/400 Ambient/100 600 <br /> 20-3203 Rejection Gas 20/100 550/600 100 <br /> Heater <br /> AES Construction Group <br /> Page 6 <br />
