Title:
NATURAL GAS DESULFURIZATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/001985
Kind Code:
A1
Abstract:
The invention pertains to the field of desulfurization and particularly relates to a natural gas desulfurization apparatus. The natural gas desulfurization apparatus provided by the invention comprises a wet desulfurization device, which is provided with a natural gas inlet and a wet desulfurization gas outlet and in which the desulfurizer is an alkali-functionalized protic ionic liquid; a drying device with a gas inlet connected to the wet desulfurization gas outlet; and a dry desulfurization device with a gas inlet connected to a dry gas outlet of the drying device. The desulfurization apparatus provided by the invention uses the wet desulfurization device to remove inorganic sulfides in natural gas, uses the dry desulfurization device to remove organic sulfides in natural gas, and has an excellent desulfurization effect; and the two desulfurization devices in the desulfurization apparatus can be arranged separately, so that the vehicle space can be used more effectively, thereby solving to some extent the problem of difficult installation and arrangement of the desulfurization apparatus caused by the limited space of the vehicle.
