Wildwood LNG Demonstration Facility The proposed demonstration plant will be considered temporary in that equipment and facilities will be removed from the site at the end of the demonstration period. Most of the major process equipment will be skid mounted and connected to each other through overhead electrical and piping connections. The foundations required for the skids will be engineered as required by the soils and seismic conditions at the site. Certain semi-permanent facilities will be required such as containment structures and the LNG product tank support piers as well as a concrete pad for mounting the processing equipment. These structures will be demolished at the end of the demonstration period, and the site restored to its original condition. Figures 5 and 6 present, respectively, plans and elevations of the process equipment, and a dimensioned layout of the equipment. The following provides a description of the major process equipment. 5.1 Gas Well Operation The source of natural gas for the project is Vieira 1-17 well. This well is located in Section 17 and is about one mile southeast of the proposed plant. The perforated interval of the well is approximately 6,400 feet below ground surface. This well was drilled in the late-1970s but was never put into production. It has been pressure tested, the results indicating a pressure of 2,660 psig. The well is connected to a series of valves. A pressure regulator will be installed at the well head to reduce the line pressure to 350 psig. An automatic shutoff valve will be incorporated into the system. The well will be connected to the project site by means of a pipeline that will pass under Wildwood Road and be routed to the processing facility. The pipeline right of way is owned by the same landowner that owns the proposed project site. The appropriate encroachment permits for the road under-crossing will be obtained from the San Joaquin County Department of Public Works. Gas from the well has been analyzed and the design criteria established for the process are 17% nitrogen, 82% methane, and less than one percent combined oxygen, carbon dioxide, and trace hydrocarbons. No water, sulfur compounds, or particulate matter were detected in the samples taken. 5.2 Gas Purification System The gas purification system consists of a gas filter, a two-bed temperature swing adsorption (TSA) unit, and post filtration equipment. Table 3 outlines the design and operating conditions for this system. The pre-filter is an in-line horizontal coalescer installed for protection of downstream equipment only. Although the gas samples taken from the well do not show any free liquid or particulate AES Construction Group Page 5
