Fluid storage and dispensing systems, and processes for supplying fluids for use thereof. Various arrangements of fluid storage and dispensing systems are described, involving permutations of the physical sorbent-containing fluid storage and dispensing vessels and internal regulator-equipped fluid storage and dispensing vessels. The systems and processes are applicable to a wide variety of end-use applications, including storage and dispensing of hazardous fluids with enhanced safety. In a specific end-use application, reagent gas is dispensed to a semiconductor manufacturing facility from a large-scale, fixedly positioned fluid storage and dispensing vessel containing physical sorbent holding gas at subatmospheric pressure, with such vessel being refillable from a safe gas source of refill gas, as disclosed herein.

1. A fluid supply system, comprising: a sorbent-based and/or internal pressure regulator-equipped supply vessel holding fluid;a dispensing assembly coupled with the fluid supply vessel, wherein the coupled fluid supply vessel and dispensing assembly are adapted to contain the fluid in the supply vessel for dispensing thereof at subatmospheric or low superatmospheric pressure from the dispensing assembly; anda mixing assembly coupled in fluid flow communication with the dispensing assembly, wherein said mixing assembly is adapted to mix dispensed fluid from the dispensing assembly with a carrier fluid in relative proportions producing a dispensed fluid/carrier fluid mixture in which the dispensed fluid is diluted to a predetermined concentration in the mixture, and to discharge the dispensed fluid/carrier fluid mixture for use, wherein the fluid contained in and dispensed from the supply vessel comprises a fluid selected from the group consisting of fumigation fluids, water treatment fluids, and fuel fluids;wherein when the fluid contained in and dispensed from the supply vessel comprises fumigation fluid, the fumigation fluid comprises phosphine gas, the carrier fluid comprises carrier gas, and the mixing assembly is adapted to dilute the phosphine gas with carrier gas to a nonflammable concentration effective for fumigation;wherein when the fluid contained in and dispensed from the supply vessel comprises water treatment fluid, the water treatment fluid comprises a water treatment gas selected from the group consisting of chlorine, bromine and chloramines; andwherein when the fluid contained in and dispensed from the supply vessel comprises a fuel fluid, the fuel fluid comprises a gas selected from the group consisting of propane, butane, natural gas, and hydrogen. 2. The fluid supply system of claim 1, wherein the fluid contained in and dispensed from the fluid supply vessel comprises phosphine gas, the dispensing assembly is adapted to dispense the phosphine gas at subatmospheric pressure, and the mixing assembly is adapted to dilute the phosphine gas with carrier gas to a non-flammable concentration of phosphine effective for fumigation in the dispensed phosphine gas carrier gas mixture, that is in a range of from 2 to 1000 ppm. 3. The fluid supply system of claim 2, wherein the mixing assembly is adapted to receive the carrier fluid from a source thereof, wherein the carrier fluid comprises a gas selected from the group consisting of air, nitrogen and carbon dioxide. 4. The fluid supply system of claim 1, wherein the fluid contained in and dispensed from the fluid supply vessel comprises a water treatment fluid selected from the group consisting of chlorine, bromine and chloramines. 5. The fluid supply system of claim 4, wherein the mixing assembly is adapted to receive the carrier fluid from a source thereof, wherein the carrier fluid comprises water. 6. The fluid supply system of claim 1, wherein the fluid contained in and dispensed from the fluid supply vessel comprises a fuel fluid selected from the group consisting of propane, butane, natural gas, and hydrogen. 7. The fluid supply system of claim 6, wherein the mixing assembly is adapted to receive the carrier fluid from a source thereof, wherein the carrier fluid comprises air. 8. The fluid supply system of claim 1, as comprised in a motive vehicle. 9. A fumigation system, comprising a sorbent-based and/or internal regulator-equipped supply vessel holding phosphine and coupled with a dispensing assembly, wherein the supply vessel and dispensing assembly are adapted to contain phosphine in the supply vessel for dispensing phosphine gas at subatmospheric or low superatmospheric pressure from the dispensing assembly, and a mixing assembly coupled in fluid flow communication with the dispensing assembly, wherein said mixing assembly is adapted to mix dispensed phosphine gas from the dispensing assembly with a carrier gas in relative proportions producing a phosphine/carrier gas mixture in which phosphine is diluted to non-flammable concentration in a range of from 2 ppm to 2% in the mixture, and to discharge the phosphine/carrier gas mixture for fumigation use, wherein the carrier gas is selected from the group consisting of air, carbon dioxide, and inert gas. 10. The fumigation system of claim 9, wherein the mixing assembly comprises a venturi mixer arranged for extraction of phosphine from the supply vessel through the dispensing assembly. 11. The fumigation system of claim 9, further comprising a carrier gas source arranged in supply relationship to said mixing assembly. 12. The fumigation system of claim 11, wherein the carrier gas source comprises ambient air or filtered or purified air. 13. The fumigation system of claim 11, wherein the carrier gas source comprises nitrogen or carbon dioxide. 14. The fumigation system of claim 9, wherein the supply vessel comprises a sorbent-based supply vessel. 15. The fumigation system of claim 14, wherein the sorbent-based supply vessel holds carbon physical sorbent. 16. The fumigation system of claim 9, wherein the supply vessel comprises an internal regulator-equipped supply vessel. 17. A fuel supply system, comprising a sorbent-based and/or internal regulator-equipped supply vessel holding a fuel fluid and coupled with a dispensing assembly, wherein the supply vessel and dispensing assembly are adapted to contain the fuel fluid in the supply vessel for dispensing thereof at subatmospheric or low superatmospheric pressure from the dispensing assembly, and a mixing assembly coupled in fluid flow communication with the dispensing assembly, wherein said mixing assembly is adapted to mix dispensed fuel fluid from the dispensing assembly with air in relative proportions producing a fuel fluid/air mixture, and to discharge the fuel fluid/air mixture for use. 18. The fuel supply system of claim 17, wherein the fuel fluid comprises a fluid selected from the group consisting of propane, butane, natural gas, and hydrogen. 19. The fuel supply system of claim 17, wherein the supply vessel comprises a sorbent-based supply vessel holding carbon physical sorbent. 20. The fuel supply system of claim 17, wherein the supply vessel comprises an internal regulator-equipped supply vessel. 21. A method of supplying a fluid for use, comprising storing said fluid in a sorbent-based and/or internal pressure regulator-equipped supply vessel and dispensing said fluid from the supply vessel through a dispensing assembly, wherein the supply vessel and dispensing assembly are adapted to contain the fluid in the supply vessel for dispensing thereof at subatmospheric or low superatmospheric pressure from the dispensing assembly, and mixing dispensed fluid from the dispensing assembly with a carrier fluid in relative proportions producing a dispensed fluid/carrier fluid mixture in which the dispensed fluid is diluted to a predetermined concentration in the mixture, and discharging the dispensed fluid/carrier fluid mixture for use, wherein the fluid stored in and dispensed from the supply vessel comprises a fluid selected from the group consisting of fumigation fluids, water treatment fluids, and fuel fluids, wherein when the fluid contained in and dispensed from the supply vessel comprises fumigation fluid, the fumigation fluid comprises phosphine gas, the carrier fluid comprises carrier gas, and the mixing assembly is adapted to dilute the phosphine gas with carrier gas to a nonflammable concentration effective for fumigation;wherein when the fluid contained in and dispensed from the supply vessel comprises water treatment fluid, the water treatment fluid comprises a water treatment gas selected from the group consisting of chlorine, bromine and chloramines; andwherein when the fluid contained in and dispensed from the supply vessel comprises a fuel fluid, the fuel fluid comprises a gas selected from the group consisting of propane, butane, natural gas, and hydrogen. 22.
