2results about How to "Flexible process control" patented technology

This invention discloses a system and process for flexibly controlling liquid delivery and recirculation, relating to the field of fuel delivery system technology. The system includes a first booster pump, a second booster pump, a first fuel storage tank, a second fuel storage tank, a fuel recirculation pipeline, and a booster pipeline. The first and second fuel storage tanks are connected to the inlets of the first and second booster pumps via the booster pipeline, and the outlets of the first and second booster pumps are connected to the first and second fuel storage tanks via the fuel recirculation pipeline. The system and process for flexibly controlling liquid delivery and recirculation in this invention enables flexible control of fuel delivery and recirculation processes. By controlling the delivery of alcohol-based fuels, it achieves risk prevention, simplification, and temperature control, and allows for easy switching to meet usage requirements. It also reduces the need for fuel booster pumps and allows for redundant configuration, reducing the risk of modifying the operating equipment.

The application belongs to the technical field of metallurgy, and particularly relates to a tungsten-molybdenum waste recovery method. The method places waste tungsten material or waste molybdenum material in an electrolysis system with sodium hydroxide or ammonia water as an electrolyte, and electrolyzes the waste tungsten material or waste molybdenum material as an anode to efficiently dissolve tungsten and molybdenum in the form of ions, so as to obtain an alkaline electrolyte rich in tungstate and molybdate; and then the electrolyte is subjected to subsequent treatment to recover corresponding products, thereby realizing the unity of process shortening, environmental friendliness and efficient resource recovery.
