This is a Joint Industry Project(JIP) with 36 members. The objective was to develop an integrated model to predict paraffin deposition in two-phase (gas/oil) production systems. Three aspects were studied: flow loop and deposition, thermodynamics and fluid characterization, and heat transfer.
A single phase flow loop was designed and built. Preliminary tests runs were run using the single phase loop. A multi-phase flow loop was designed. A thermodynamic model was completed and tested against available data. The model calculates bubble points, dew points, critical points, cricondentherms, cricondenbars, and vapor-liquid phase envelopes of different fluids on a weight, mole, or volume basis. A graphical users interface was developed and final data gathered. The final report was submitted in March 2000.
The last semi-annual meeting was held on September 29, 1999 at Tulsa University. The JIP members received a proposal to expand the work and have a new contract and MMS has joined the new project, TAP Project 371.
