DYNAMIC SCALE LOOP
 

The PMAC Dynamic Scale Loop (DSL) apparatus is an invaluable research and development tool for technologists responsible for the design, operation and efficiency of water handling systems in which changes in thermal, pressure or chemical can promote the deposition of scales. The apparatus provides an accurate, reproducible and rapid method for selecting and quantifying the most effective means of controlling scale deposition under dynamic conditions. PMAC DSL systems are being used by many laboratories around the world to provide accurate and repeatable results by leading Major Oilfield Chemical Companies.

The system is designed for applications where the process or reservoir temperature exceeds 100°C and/or the impact of pressure on scaling tendencies needs to be studied. It is the only method available for studying Anhydride deposition under dynamic conditions. In cases where specialized tests involving the compatibility analysis of three “stable” waters, a third pump option is available. The standard PMAC DSL system features two HPLC pumps with 10cc pump heads, which include ceramic insert sleeves to minimize corrosion. It also includes an oven or water bath, differential and system pressure sensors, and a solvent organizer, all controlled via a PC with logging capabilities. The default setup provides a maximum flow rate of 20 ml/min. There is an optional 50cc pump head available, though it is not recommended for tests due to excessive shear.

The apparatus is available in two versions with different maximum working pressures: 2900 psi and 5800 psi. Both versions can operate within a temperature range from ambient to 300°C with the oven. Alternatively, a water bath can be used to achieve lower temperature range down to -20°C, allowing for simulation of field conditions. The flow configuration is programmable with flow ratios from 0-100%, allowing for single pump flow if necessary. The electronics are all fully enclosed in IP rated boxes for enhanced safety. The oven comes with an independent temperature control and thermal cut-out as standard. The system pressure and the differential pressure both come with pre-set inbuilt safety cut-out and bypass. Backpressure control is through a back pressure regulator valve installed at the front of the unit for easy access. All High Pressure pipework is made from stainless steel. However, optional Monel can be used in heated zone.
