1. A compressor train for a chemical plant, comprising:
a compression unit comprising a rotation shaft rotatable about an axis as a center and configured to compress a process gas of the chemical plant;
a motor comprising an output shaft rotatable about the axis as a center and configured to drive the compression unit and to adjust a rotation speed of the compression unit;
a steam turbine comprising a turbine rotation shaft rotatable about the axis as a center, rotated by steam generated in association with treatment of the process gas of the chemical plant at a rotation speed equal to or lower than a rotation speed of the motor, and configured to assist rotation of the motor;
a steam introduction line through which the steam flows toward the steam turbine; and
a main trip and throttle valve disposed on the steam introduction line and configured to block or cause the steam to flow into the steam turbine, wherein
the steam turbine is disposed between the motor and the compression unit in an axial direction in which the axis extends, and
the rotation shaft, the turbine rotation shaft, and the output shaft are disposed on a same straight line such that the axis is shared as a center line of the rotation shaft, a center line of the turbine rotation shaft, and a center line of the output shaft.
