AirFlow(@STP)Application48 inches 92 CFM Low level step test3 HP, 240V, 60Hz 90 inches 147 CFM High level step testA barometer was used prior to the start of extraction operations at each well and periodically during eachtest to determine the range of barometric pressure change that occurred over the time frame of the SVEdemonstration. There was no significant barometric pressure change (i.e., less than +/- one millibar) thatoccurred during the demonstration that required adjustment of the differential vacuum readings taken atthe monitoring wells.An example of the step test procedures can be demonstrated by considering the flow tests conducted atU12-VP1. The first blower used, the REGENAIR TM SDR4, the larger of the two blowers was installedto the SVE process system and tested at increments of constant flow as shown in Table 4-3. The blowerwas started with the dilution air valve in the fully open position. The valve was closed partially to aposition that applied enough vacuum to induce flow to greater than 2 cfm (flow was established at 2.75cfm at the given vacuum) and remained approximately steady at 2.75 cfm for 23 minutes. At that time,the vacuum relief valve was closed further to induce a vacuum of 51.5 cfm and a flow of 5 cfm(approximately doubling the initial flow) at the wellhead. Over the next 14 minutes, vacuum and airflowwere monitored at the extraction well and vacuum was monitored at the monitoring wells. The dilutionair valve was closed further (but not fully) to apply a vacuum that varied between 52 and 53 inches ofwater and increasing flow to 7.5 cfm.
