PhD Student

Start date: February 2011
Project: Dynamics of crystal growth and sedimentation in a pilot scale MEG reclamation rig
Sponsor: CONACyT
Email: rafael.lopezrodriguez@postgrad.manchester.ac.uk

Education:

MSc in Chemical Engineering, Technological Institute of Celaya, México. (2009).

BEng in Chemical Engineering, Autonomous University of Yucatán, México. (2005).

Before beginning the PhD, I worked in a Mexican refinery and a natural gas processing plant as a Technical Services Engineer. More recently, I worked as lecturer at undergraduate level in the Chemical Engineering Faculty on the Autonomous University of Yucatan.

Research project:

Gas exploration requires sea bed pipelines at increased depths and distances as demand increases and older fields run down. This has created a growing market for solutions to the associated technological challenges. A principal difficulty is the formation of solid particles from a reaction of water and methane gas, called hydrates, under the extreme temperatures and pressures. The injection of monoethylene glycol (MEG) into pipelines is a proven method for preventing hydrate formation based on decreasing the temperature at which hydrates form. It is desirable to reclaim this MEG at the end of the pipeline.

A barrier to MEG reclamation is the accumulation of dissolved salts in the process. This project will conduct a study of the fundamental crystallization and sedimentation processes which occur within a MEG reclamation process.
