Title:
GAS HYDRATE PRESSURE-MAINTAINING REPLACEMENT APPARATUS AND METHOD USED FOR IN-SITU RAMAN ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2021/035753
Kind Code:
A1
Abstract:
A gas hydrate pressure-maintaining replacement apparatus and method used for in-situ Raman analysis, capable of implementing comprehensive experiments such as the formation/decomposition/replacement of high-pressure gas hydrates, and performing in-situ Raman characterisation. The apparatus comprises a reaction kettle system with a temperature control unit, a pressure-control gas supply system, a pressure-maintaining system, a gas replacement system, a sample pre-cooling system, a vacuum system, and a data collection and processing system. The apparatus can solve the problem of the Raman peak of the 512cage being covered by the Raman peak of the gas when performing in-situ Raman characterisation of a high-pressure gas hydrate in a reaction kettle (3), and also solve problems such as experiment errors caused by sample transfer/difficulty of sampling for non-in-situ Raman characterisation.
