摘要
水合物技术应用潜力巨大,研究水合物形态学有助于解决生产中的水合物堵塞等问题。本文主要从水合物成核位置及生长方式和水合物生长形态的影响因素两方面进行概述:指出气液界面、气液固界面、液滴界面是常见的成核位置;介绍了水合物沿气液界面横向生长及沿气液界面向液(气)相生长两种方式;分析了操作压力、过冷度、添加剂种类及含量和气体组成对水合物生长形态的影响。这为解决水合物技术工业应用中易出现的堵塞问题提供了新思路。
The potential for hydrate technology is considerable,and the study on hydrate morphology can help to solve problems such as hydrate plugging in production.The location of hydrate nucleation and growth patterns and the factors influencing hydrate growth morphology are summarised.It is observed that the gas-liquid interface,gas-liquid-solid interface,and liquid-droplet interface are the common nucleation locations.Furthermore,the two ways of hydrate growth are introduced.The growth of hydrates can occur along the gas-liquid interface and along the gas-liquid interface to the liquid(gas)phase.The effects of various factors on the growth morphology of the hydrate are also analysed,including the operating pressure,the degree of subcooling,the type and content of additives,and the composition of the gas.This provides ideas for solving clogging problems in industrial hydrate applications.
