| Abstract | The simulating experiment of gas hydrates often lasts a long time, has a high pressure (usually equal or more than 38bar) and has many steps. A high-pressure console was developed to lighten labor intensity and guarantee experiment safety in the Synthetic Experimental System of Gas Hydrates Simulation (SESGHS). Gas inlet/outlet, cell pressure test and overpressure protection are all managed on the console. The overpressure protection module included a gas-control valve NV1-20-6M-ATC, a solenoid valve VP542, a relay OMRON/ G2R-1, a multi-function card PCI-1711, a pressure sensor and the corresponding software. The acquired pressure data was judged whether to surpass the alarm value, if so, alarm would be send out. And if over the unloading value, number 1 will be send to the channel connecting PCI-1711 card and the relay, then relay is switched on to make electromagnetic valve open and let low pressure gas enter so that the gas-control valve can release high pressure automatically. The whole pressure-control module was operated successfully in the experiments of gas hydrates formation, drilling fluids tests and mini-drilling simulation. It worked steadily, operated conveniently and had high sensitivity for overpressure protection, which largely enhanced the safety of the experiments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
