Abstract: A method for comprehensively processing noble lead provided and utilizes two instances of vacuum distillation to realize an open circuit of arsenic, lead, antimony and bismuth and the high-efficiency enrichment of precious metals of gold and silver, and can obtain elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy and a copper alloy, respectively. The lead-bismuth-antimony alloy, the silver alloy and the copper alloy are processed by oxidation refining, electrorefining and chlorination refining to obtain refined lead, refined antimony, antimony trioxide, electrolytic silver and electrolytic copper, and to realize gold enrichment. The entire process has advantages of high metal direct yield, low energy consumption, short flow chart, simple equipment, etc., and vacuum distillation belongs to a physical process in which the alloy can be separated only by means of the difference in saturated vapor pressure between the metals, without generation of wastewater, waste gas and waste residue.

Abstract: The invention discloses a method for simultaneously removing SO2 and NOx in flue gas: uniformly mixing a water-soluble ruthenium salt with ammonia water to obtain an aqueous solution of a ruthenium-amine complex; subjecting the flue gas and the aqueous solution of the ruthenium-amine complex to a countercurrent contact reaction under the temperature of 5-60° C., pH of 7.5-12 to obtain a solution A and purified gas; discharging the solution A of the step (2) into a crystallization tank to crystallize and separate an ammonium salt to obtain a solution B, returning the solution B to replace the aqueous solution of the ruthenium-amine complex. The invention utilizes the ruthenium-amine complex having a strong capability of complexing with NO as well as residual oxygen in the flue gas to carry out liquid phase catalytic oxidation to convert the NOx into ammonium nitrate, and the removal efficiency of the NOx and the SO2 is high.

Abstract: The provided are a method, system, and medium for active arc-extinguishing voltage-current conversion in distribution networks. The method includes: detecting a single-phase-to-ground fault in the distribution network and identifying the target faulty phase; injecting compensating currents into the target faulty phase to reduce its voltage; measuring the residual current at the fault point during the injection of compensating currents and the zero-sequence voltage of the target faulty phase; determining a critical zero-sequence voltage threshold based on the residual current at the fault point and assessing whether this critical value exceeds the present zero-sequence voltage; if so, ceasing the injection of compensating currents into the target faulty phase and instead injecting active arc-extinguishing currents at the neutral point of the distribution network to mitigate ground currents at the grounding points of the distribution network. The objective is to enhance the applicability of arc-extinguishing methods for ground faults in distribution networks.
