A COdesorption system suitable for limited space in a complex sailing region comprises an exhaust boiler, a compact COabsorber, a compact COlean-rich liquid heat exchanger, a compact COdesorber, a compact COrich liquid preheating device, a compact COrich liquid reboiling pre-desorption device and an intelligent control platform. Further, a global optimization control method for the COdesorption system suitable for limited space in a complex sailing region is further established based through a knowledge and data-driven exhaust extraction flow accurate-prediction model for a heat source of a COrich liquid preheating device and a steam extraction flow accurate-prediction model for a heat source on an upper section of a COrich liquid reboiling pre-desorption device to realize flexible control of operation parameters of the desorption system under different operating conditions of an engine.

The present invention relates to a method for carbon dioxide capture and concentration by partitioned multistage circulation based on mass transfer-reaction regulation. In the present invention, multiple means such as multistage circulating absorption, intelligent multi-factor regulation, pre-washing and cooling, inter-stage cooling, post-stage washing, slurry cleaning, cooling water waste heat utilization, small-particle-size and high-density spraying, external strengthening field such as a thermal field/ultrasonic field/electric field, and catalysis by composite catalyst are adopted, so that the target for low cost, low energy consumption, stability and high efficiency is realized. The secondary pollutants are effectively inhibited while carbon dioxide is efficiently captured; meanwhile, high-efficiency capture, low-energy desorption, and high-purity concentration of carbon dioxide are implemented. From top to bottom in sequence, the multistage circulation is used to remove aerosols, improves carbon capture efficiency, maintains absorption rate, concentrates solution, which reduces the carbon emission reduction cost.

A method for authentication is disclosed. The method may be implemented by a terminal device. The method may comprise generating, by a starting unit of the terminal device, process information of a process of the terminal device before starting the process, transmitting, by the starting unit, the process information to an authentication proxy of the terminal device, requesting, by the process, the authentication proxy to authenticate the process after the process is started, obtaining, by the authentication proxy and from system resources of the terminal device, process information corresponding to the process, and determining, by the authentication proxy, that the process is legal if the obtained process information is the same as the process information transmitted to the authentication proxy.
