Abstract: A method for controlling the Btu content of a flare gas to combusted in a flare stack comprising a flare tip is provided. The method includes, introducing a first gas stream including nitrogen to be flared, the first gas stream having an initial Btu content, providing a supplemental fuel gas stream, and combining the first gas stream with the supplemental fuel gas stream, thereby obtaining a flare gas stream having a final Btu content measured at the flare tip.

Abstract: TurbinAL™ is a high-flow carbon dioxide system providing continuous, pressure and temperature regulated gas supply of carbon dioxide for turbine system purging. In a preferred embodiment, the TurbinAL™ system has: a) Four or more dip-tube equipped carbon dioxide cylinder six- or sixteen-packs with integral check valves, flow restriction orifices, and single outlet manifolds; b) Two flow manifolds which are connected to the packs with flexible gas safety lines; c) A transducer controlled automatic switchover manifold that switches gas flow from one flow manifold to the other with no interruption in gas flow; d) An electric heater system designed to vaporize liquid carbon dioxide drawn from a cylinder (via the dip tube) to be supplied to the turbines as a temperature controlled gas; e) A programmable logic controller (PLC) to automatically control and monitor system functions; and f) A flow control device to prevent excess flow to the turbine(s).

Abstract: An apparatus that is usable with an inlet port to a storage system includes a cover and a locking mechanism. The cover is adapted to, in a first state, engage the inlet port to prevent access to the inlet port and in a second state, be disengaged to release the cover from the inlet port. The locking mechanism is adapted to secure the cover in the first state.

Abstract: A method is disclosed for using the simple, environmentally friendly organic compounds gamma-butyrolactone and benzyl alcohol to develop and to strip free radical-initiated, addition polymerizable resists, cationically cured resists and solder masks and Vacrel photoresists. In all cases the developers and strippers include gamma butyrolactone or benzyl alcohol. The developers and strippers optionally also include a minor amount of methanol, ethanol, isopropyl alcohol, propylene glycol monomethylacetate, ethylene glycol monomethyl ether, formamide, nitromethane, propylene oxide, or methyl ethyl ketone, acetone and water. During development of the photopatterned resist or solder mask, the unpolymerized regions are dissolved in the disclosed developers. During stripping of the resist or solder mask, the polymerized regions are debonded from a circuit board in the disclosed strippers.

Abstract: Disclosed is a method of treating a process stream from a process producing a non-biodegradable alkylene carbonate stream. The alkylene carbonate is hydrolyzed in a strong, aqueous, alkaline solution to form an aqueous alkaline solution of the corresponding alkylene glycol. This solution is then acidified to a pH of about 8 to 8.5. The acidified solution is aerated in activated sludge to reduce the biological oxugen demand (BOD) of the solution.
