摘要： Methods for recovering organic heteroatom compounds from a hydrocarbon feedstock include feeding into a contactor a hydrocarbon feedstock and an aqueous solvent to form an extraction mixture of the aqueous solvent with the hydrocarbon feedstock. The hydrocarbon feedstock includes a hydrocarbon and an organic heteroatom compound. The aqueous solvent includes an ionic liquid formed from pressurized carbon dioxide and water. A pressure and temperature of the extraction mixture may be established that together tune the aqueous solvent to selectively form a solvent complex with the at least one organic heteroatom compound. Then, the solvent complex is extracted to a recovery vessel from the extraction mixture in the contactor. By adjustment of a recovery temperature of the recovery vessel, a recovery pressure of the recovery vessel, or both, the solvent complex decomposes into carbon dioxide and the organic heteroatom compound. The organic heteroatom compound is then recovered from the recovery vessel.

摘要： Embodiments of this disclosure are directed to a parking indicator comprising a vehicle contact body, a pivoting contact body support, an elongated visibility indicator, an indicator actuating mechanism, and an indicator retracting mechanism. The pivoting contact body support is attached to the vehicle contact body and is configured to permit the vehicle contact body to pivot to a horizontally-oriented position when the vehicle contact body is grounded via the pivoting contact body support and is contacted by a vehicle entering a parking space occupied by the parking indicator. The elongated visibility indicator is mechanically coupled to the vehicle contact body via the indicator actuating mechanism such that the indicator actuating mechanism upholds the elongated visibility indicator in an extended position. The indicator retracting mechanism is configured to retract the elongated visibility indicator to a retracted position when the vehicle contact body pivots from the vertically-oriented position to the horizontally-oriented position.
