Job description
COURBEVOIE(PLD)-COUPOLE(FRA)
Description du poste
Contexte et environnement professionnels:
The Acid Gas Entity contributes to various tasks related to gas sweetening: process development and operational assistance, research, and consolidation of knowledge
Objectifs et activités de la mission:
Because natural gas is the fossil energy carrier which, when burned, emits the lowest amount of CO2 per unit of energy output, its importance in the energy mix is expected to strongly increase in the coming decades. A significant part of the world’s natural gas reserves is acid, as they contain H2S and CO2, and their removal is necessary before entering the gas pipelines and the liquefaction units (for LNG). The most common method to sweeten the gas (i.e., to remove these acidic components) is absorption into a liquid solvent, particularly aqueous alkanolamine solutions.
The development of new solvents to capture acid gas has been an ongoing research topic since decades. New solvents are required for task-specific absorption and/or to lower the high energy consumption of the absorption regeneration unit. The topic has recently received renewed attention because of the rising importance of CO2 capture to mitigate climate change.
Key in the development of new solvents are the various Vapor Liquid Equilibrium curves (VLEs) which give the amount of acid gas absorbed by the liquid solvent as a function of the partial pressure of the acid gas in the vapor phase. Knowledge of the VLEs at various temperatures allows for a first estimate of the performance and of the design of the absorption unit. The VLEs for various potentially interesting new solvents are being experimentally determined for a few pressures and temperatures.
The aim of the internship is to use those experimental data points to determine the parameters of a thermodynamic model which predicts VLE data over the whole T, P range of interest for the absorption process, and for a particular solvent. The thermodynamic model will be inserted in a process simulation tool of an acid gas removal unit (e.g. Aspen). This tool will subsequently be used to evaluate the performance of the new solvent.
This internship requires an interest in gas treatment and CO2 capture, in the development of thermodynamic models and in the use of process simulation tools. The intern should be able to write and read technical English.
Compétences développées durant la mission: - Understanding natural gas treatment processes
- Understanding complex thermodynamic/kinetic modelling in general and more specifically of an acid gas absorption unit
- Use of process simulation tools (e.g. Aspen) to evaluate different solvents for an acid gas absorption unit
