Topic: Deep Sea Underwater Operation Simulation Technology and Application
Abstract: This presentation starts with a short introduction to the characteristics of deep-sea underwater operations with important problems in engineering and then gives the developments of a Modeling & Simulation-based method for previewing operation plans and dynamic analysis with their applications in various actual operations. A distributed co-simulation architecture is presented in the base of available realize the integrated management of dynamic information and the reliable extension of interactive simulation in the process of simulating operations. The key technology of modeling and visualizing the rigid-flexible multi-body coupling dynamics based on the multi-body dynamics, computational dynamics, and the real-time rendering method is discussed which can realize the accurate real-time solution of multi-body coupling operations. The system composition of the ROV will be introduced which had obtained the international Class-A standard certification of the China Classification Society. The selected examples include the installation simulation of the "Deep Sea No. 1" semi-submersible platform and underwater oil and gas production equipment; the simulation of SCR monitoring equipment installation in Lingshui 17-2 oilfield. The simulation results are compared with the actual operation results to demonstrate the deep-sea underwater operation simulation technology.

Topic: Application of Supersonic Separation Technology in the Field of Carbon Capture
Abstract: Supersonic separation is a clean technology applied in gas processing and treatment. At present, it is mainly used for natural gas liquefaction and dehumidification, and has achieved good results in many natural gas fields. In this technology, the characteristics of cyclone separation, shock wave pressurization, phase transition are concentrated in a separation equipment with compact structure and small volume, called supersonic separator, which is the core equipment of supersonic separation technology. Excitingly, previous investigations have found that Laval nozzles are able to condense CO2 from power plants into liquids, thereby separating CO2, which means that these investigations have discovered a potential CO2 capture approach. Supersonic separation does not require complex membrane materials, nor does it require adsorbents and absorbents. It can spontaneously separate CO2 from flue gas under the drive of pressure. In addition to the above advantages, supersonic separators also have the advantages of stable operation, small size, low maintenance and operation cost and is a new technology in the field of carbon capture.
