EQUILIBRIUM BOMB FOR STUDYING PHASE BEHAVIOUR OF HYDROCARBONS

摘要

The inventive equilibrium bomb for studying a phase behavior of hydrocarbons comprises a temperature-controlled high-pressure cylindrical container (1) provided with viewing ports (2) embodied at a level of a light source (3), top (10) and bottom (11) reflectors being disposed inside the container and rigidly connected to each other by means of a membrane (12) and a dividing piston (13) fixed to the bottom reflector (11). Said top reflector (10) is made to the shape of a cylinder whose base comprises a recess as viewed from the membrane which forms two symmetrical mirror surfaces tilted at an angle of 45° with respect to the cylinder axis. The bottom reflector (11) is made to the shape of a cylinder whose one base comprises two flat mirror faces symmetrically tilted at an angle of 45° with respect to the cylinder axis, the other base thereof is provided with a radial slot which is oriented perpendicular to the plane of the membrane (12). The reflectors are spaced with respect to a container interior wall. Said bomb is provided with a bypass tube (15) which connects spaces above and below the piston to each other by means of a stop valve. The radial slot of the bottom reflector is arranged in a perpendicular direction with relation to the membrane (12) which is fixed with the aid of two grooves on the interior surface of the container (1) in a perpendicular direction to the axis of the viewing ports (2).
