The invention relates to a process for obtaining at least one aromatic amine from a liquid mixture comprising water and the at least one aromatic amine by extracting with at least one nitroaromatic in an extraction column to form an essentially water-comprising raffinate stream and an extract stream comprising the at least one nitroaromatic and the aromatic amine. The computer system includes a remote console functionality assist logic structure for effectuating the sending and receiving of signals from the remote terminal. The SatComm Gateway then utilizes a low-Earth Orbit satellite constellation to transmit information to a central data collection center. When the second path is selected, the amplified signal is received at a second amplifier, amplified to a second power level over a low frequency range, and transmitted to the signal output. The displaying unit displays the values of the physical quantity of the channels while changing a display condition in accordance with the size relationship between the values of the physical quantity and the threshold level.
