The study of calcium carbonate (CaCO/sub 3/) scale inhibition in geopressured energy systems has led to the development of a flow system with high temperature and pressure capability. A high-pressure (performance) liquid chromatograph (HPLC) was modified by the addition of a backpressure valve and by bypassing the HPLC packed column. Solution mixing and temperature are computer-controlled, and CaCO13B precipitation is monitored by in-line pH measurement. Simulated and real brine samples were used to evaluate scale inhibitors, and CaCO/sub 3/ precipitation was related to the saturation index, I/sub s/.
