Simulation analysis and experimental research of a sampling valve for the seafloor natural gas hydrates survey

Autor: Hui Ji, Li Ouyang, Fanglong Yin, Songlin Nie

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering. 233:1137-1150

A hydraulically actuated sampling valve is developed for the sub-sea situ pore-water and bottom seawater sampler. A unique pressure compensation design for the valve core is adopted in the sampling valve, which makes the sampling valve open or closur

Collection of Gas-Tight Water Samples from the Bottom of the Challenger Deep

Autor: Shuo Wang, Shijun Wu, Canjun Yang

Publikováno v: Journal of Atmospheric and Oceanic Technology. 35:837-844

A new gas-tight pair sampler was designed for the collection of gas-tight fluid samples from the hadal zone. The sampler uses two titanium bottles and one sampling valve to collect two samples at once. The sampler can be deployed in the deepest trenc

On-line micro GC testing of protium analysis in DT fuels from TCAP products

Autor: Lidong Xia, Zhang Weiguang, Yiwu Mao, Chen Xiaohua, Xiaosong Zhou, Shuming Peng, Xinggui Long, Hairong Li, Chengwei Wen, Weiwei Wang

Publikováno v: Fusion Engineering and Design. 170:112481

To support Chinese Inertial Confined Fusion research, a thermal cycling absorption process (TCAP) system was previously developed for protium removal from D–T fuels. However, to monitor the product quality in each TCAP cycle (10 min), an on-line an

A Multiconfiguration Valve for Uninterrupted Sampling from Heterogeneous Slurries: An Application to Flow Chemistry

Autor: Howard N. Hunter, Jee S. Kwak, Michael G. Organ, Debasis Mallik, Wenyao Zhang, Daniel Tsoy

Publikováno v: Organic Process Research & Development. 21:1051-1058

Heterogeneous chemical reactions that produce precipitates are generally considered to be poor choices for adaptation to a flowed format. Among various complexities associated with working with slurries, sampling from a moving slurry is perhaps the m

Experimental Verification of the Filtration Phenomena in Hydraulic Systems

Autor: D. Rabsztyn, K. Klarecki

Publikováno v: Advances in Intelligent Systems and Computing ISBN: 9783030158569

Article presents comparing of the authors’ mathematical model of the filtration phenomena with the results of the experimental tests. Experimental studies have shown that the concentration of solid contaminant particles in the hydraulic fluid is af

A new serial sampler for collecting gas-tight samples from seafloor cold seeps and hydrothermal vents

Autor: Shijun Wu, Wang Xun, Mengran Du, Shuo Wang, Canjun Yang

Publikováno v: Deep Sea Research Part I: Oceanographic Research Papers. 161:103282

This paper details the development and application of a new serial sampler capable of acquiring multiple deep-sea gas-tight fluid samples. It consists of a custom-made multiport sampling valve with six sampling cylinders distributed around it in a ci
