Yiwu Jiangna has obtained a patent for a coal tar hydrogenation unit that enables efficient utilization of acidic dry gas. According to information from the Intellectual Property Office, Yiwu Jiangna New Materials Co., Ltd. has been granted a patent titled “A Coal Tar Hydrogenation Unit for Efficient Utilization of Acidic Dry Gas”; the approval number is CN222524449U, and the application was filed in May 2024. The patent abstract indicates that this utility model relates to the field of chemical processing auxiliary technologies, and specifically to a coal tar hydrogenation device that makes efficient use of acidic dry gas. It includes a hydrogenation reaction tank; at the upper part of this tank, there are sequentially arranged a liquid inlet, a hydrogen inlet, an exhaust port, and temperature and pressure gauges. Outside the hydrogenation reaction tank, there is a heating furnace, which surrounds the middle and lower parts of the tank. At the bottom of the heating furnace, there is a combustion furnace; on the left side of this combustion furnace, there is a gas supply port, and to the left of that port, there is a gas inlet pipe. On the left side of the heating furnace, there is also a drying tank, with the upper end of the gas inlet pipe extending into the interior of this drying tank. Inside the left side of the drying tank, there is a gas delivery pipe, and on the left side of the drying tank, there is a desulfurization tank. The upper end of the gas delivery pipe is connected to the right side of the upper end of the desulfurization tank. This practical new design facilitates external heating as needed; during heating, it enables efficient use of acidic dry gas to supply combustion materials, thus making its use more efficient and convenient.
