The Mini AutoClave (MAC) for quick scan purposes is a setup for medium throughput vapour-liquid-equilibrium (VLE) equipment where six experiments can be performed simultaneously. An advantage is the relatively small volume of solvent needed to run a proper test. All six reactors can run independently of each other and can be started and stopped at any time. A typical measurement takes about 24 to 48 hours. The test set-up is divided into two temperature sections. Three reactors are heated to 40°C by a water bath and three reactors are connected to an oil bath and can be heated to any temperature between ambient and 120°C and these three reactors run at the same temperature. Vaporliquid equilibrium measurements are performed in 0.1 litre reactors equipped with a magnetic stirrer and a pressure gauge. Typically, 0.05 litre of solvent is used. The solvent in the reactor can be heated up and equilibria can be determined at a constant temperature of the solvent. From these data so-called pressure-loading (P-α) curves can be constructed. The pressure (P) is obtained as a function of the loading (α). The loading is expressed in mol CO2/mol solvent. For the glass reactors, measurements have an upper limit of about 7 bars. For safety reasons, a high pressure limit of about 5 bar was chosen. This implies that the P-α curves, measured at the MAC set-up, range from about 2 to 5000 mbar.
