..., however, can lead to wasted CAPEX and/or OPEX, and may not work for economically challenged/ marginal projects. To address this problem, we have built a large-scale flow loop (4" pipe ID, and 120 ft long test section) for testing wax deposition. A variety of experiments were performed changing...

... consisted of three main test sections, with pipe inclinations 0, 0.5 and 90 degrees, and with approximate lengths of 380 m, 380 m and 50 m, respectively. The experiments were performed at system pressures 20, 45 and 85 bara. The primary focus of the campaign was on liquid dominated flows in horizontal/near...
