Definitions

  • a storage wellhead allowing on-line system maintenance and testing is provided. Including at least two fluidically parallel gas passages adapted to allow testing or maintenance of one gas passage, while the other gas passage remains in service.
  • the gas may be hydrogen. Also including at least two fluidically parallel liquid passages adapted to allow testing or maintenance of one liquid passage, while the other liquid passage remains in service.
  • the liquid may be brine.
  • high pressure is defined as a gas storage pressure at or above 2401 psig (165,54 bar).
  • This invention claims the design of the storage wellhead for high pressure gas to include two outlets on both the gas and the liquid wellhead spools to facilitate testing and maintenance of valves so as to not interrupt gas or liquid flow.
  • gas storage pressures 2401 psig (165,54 bar) to 4000 psig (275,79 bar)
  • all flanges and valves meet API 5000 (API 5M)
  • API 10000 API 10M
  • the wellhead design includes hydraulically operated valves of the required pressure rating for use as emergency shutdown devices (ESDs) on the high pressure gas and brine systems.
  • the piping size of the hydraulically operated valves can be from 2 inch (5,08cm) up to 9 inch (22,86 cm).
  • the protection of brine and water systems which operate at lower pressure require an additional automatic valve in the line to create a double block on the brine out of the storage well. All automated valves in this invention are designed to fail closed on loss of signal, loss of hydraulic pressure, and on loss of instrument gas.
  • liquid master valve, high pressure gas wing valves, brine wing valves, and brine logging valve design includes the use of manual valves of the required pressure rating.
  • the piping size of the manually operated valves can be from 2 inch (5,08 cm) up to 9 inch (22,86 cm).
  • each wellhead spool has a flange connection for pressure indication.
  • a storage wellhead allowing on-line system maintenance and testing is described.
  • a gas wellhead spool 117
  • a liquid passage 101
  • the gas wellhead spool (117) is adapted to allow testing or maintenance of one gas passage (103,104), while the other gas passage remains in service.
  • the storage wellhead may be designed such that each gas passage (103, 104) is capable of conveying the entire design gas flowrate.
  • the gas may be hydrogen.
  • Each gas passage may comprise an automatic gas valve (107,108).
  • Each gas passage (103, 104) may comprise a gas wing valve (105, 106). After passing through the gas passage (103, 104), the gas wing valve (105, 106), and the automatic gas valve (107, 108), the gas exits the storage wellhead through conduit (109), to be utilized downstream.
  • FIG. 1 illustrates the situation where one automatic gas valve (107) is closed, as would be the case during testing, while simultaneously the other automatic gas valve (108) is open and allowing gas to pass.
  • each liquid passage (110, 111) is capable of conveying the entire design liquid flowrate.
  • the liquid may be brine.
  • Each liquid passage may comprise an automatic liquid valve (114,115).
  • Each liquid passage (110, 111) may comprise a liquid wing valve (112, 113). After passing through the liquid passage (110, 111), the liquid wing valve (112, 113), and the automatic liquid valve (114, 115), the liquid exits the storage wellhead through conduit (116), to be utilized downstream.
  • FIG. 1 illustrates the situation where one automatic liquid valve (115) is closed, as would be the case during testing, while simultaneously the other automatic gas valve (114) is open and allowing gas to pass.
  • the gas passage (103, 104), or automatic gas valve (107,108), testing may occur at predefined first intervals.
  • the predefined first interval may be once a month.
  • the liquid passage (110,111), or automatic liquid valve (114,115), testing may occur at predefined second intervals.
  • the predefined second interval may be once a month.
  • the gas wellhead spool may operate at a pressure of greater than 2400 psig (165,47 bar).
  • the gas wellhead spool may operate at a pressure of less than 4000 psig (275,79 bar).
  • the gas wellhead spool may operate at a pressure of less than 3000 psig (206,84 bar).
  • All automatic gas valves (107,108) and all automatic liquid valves (114,115) may be tested at a predefined third interval.
  • the predefined third interval may be every six months.
  • the automated valves may be hydraulically operated.
  • the test may comprise measuring the time for each valve to move from a fully open position to a fully closed position.
  • the liquid wellhead spool may operate at a pressure of greater than 2400 psig (165,47 bar).
  • the liquid wellhead spool may operate at a pressure of less than 4000 psig (275,79 bar).
  • the liquid wellhead spool may operate at a pressure of less than 3000 psig (206,84 bar).
