The VES will operate continuously twenty-four <br /> hours per day seven days per week for a period of approximately one year. <br /> ti <br /> Process Flow.Rates <br /> The maximum achievable process rate for a YES is directly related to the <br /> flaw capacity of the vacuum <br /> concentration that can be abatpump and the maximum hydrocarbon <br /> ed by the emissions control system. For <br /> this particular syste!n, the vacuum extraction capacity of the pump unit <br /> is 190 scfm.
