Abstract
When exposed to gases such as methane and carbon dioxide at medium to high pressures, water forms cages around the gas molecules known as gas hydrates. Under typical conditions, two types of hydrate can form; structure I hydrates are made up of 46 water molecules and have 8 cavities which can be filled by guest gases, while structure II hydrates are made up of 136 water molecules and have 24 cavities. The purpose of this project was to take existing research and develop a lightweight web application that can, for a given set of components, temperatures, and (optionally) inhibitors, to return the equilibrium pressures at which hydrates will form under those conditions; additionally, functionality exists for a “what if” calculation, wherein the user can input a desired equilibrium temperature and get a required amount of a specific inhibitor required to achieve the desired temperature. The webapp is written in Python, and the web interface is built on the Streamlit library. The equilibrium calculations are based on the Klauda-Sandler model and the inhibitor model used is the Hu-Lee-Sum Correlation. This simulation app will be especially useful to hydrate researchers and any industry which deals with high-pressure gases which could be exposed to water, such as in natural gas pipelines.
