EQUILIBRIUM BOMB FOR STUDYING PHASE BEHAVIOUR OF HYDROCARBONS

摘要

The inventive equilibrium bomb for studying phase behaviour of hydrocarbons comprises a thermostatic high-pressure cylindrical container (1) provided with viewing ports (2) embodied at the level on a light source (3), top (10) and bottom (11) reflectors which are 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 embodied in the form of cylinder whose base comprises a recess on the side of the membrane which forms two symmetrical mirror surfaces tilted at an angle of 45 DEG with respect to the cylinder axis. The bottom reflector (11) is embodied in the form of a cylinder whose one base comprises two flat mirror faces symmetrically tilted at an angle of 45 DEG with respect to the cylinder axis, the other base thereof is provided with a radial slot which is oriented perpendicularly to the plane of the membrane (12). The reflectors are spaced with respect to the internal wall of the container. Said bomb is provided with a bypass tube (15) which connects spaces above and below the piston by means of a closing 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 embodied on the internal surface of the container (1) in a perpendicular direction to the axis of the viewing ports (2).
