Abstract: PURPOSE: A Doppler frequency transition compensating method using an FFT(Fast Fourier Transform) is provided to compare signal component powers of two frequencies adjacent to an IF(Intermediate Frequency), and to control an output frequency of a local oscillator. CONSTITUTION: After performing a frequency transition to a base band, a system detects a Doppler frequency transition.

The system performs an FFT(Fast Fourier Transform) for the signal, and calculates a power distribution of a discrete frequency component. The system estimates a remaining carrier wave frequency error. The system reduces noises by using an LPF(Low Pass Filer). The system controls a frequency of a local oscillator, and compensates the remaining carrier wave frequency error. If errors are generated while compensating the remaining carrier wave frequency error, the system returns to a remaining carrier wave frequency compensation step or an error estimating step according to an error kind.

Abstract: Crude phthalic anhydride (PSA) is catalytically produced from oxygen-containing gas and orthoxylol or naphthalene at temperatures in a range from 300 to 500  DEG C. The mixture containing gas and PSA vapour withdrawn from the reactor is first led through a cooled, continuously operating liquid separator. A first liquid, PSA-rich stream is withdrawn from the liquid separator, as well as a separate residual mixture of gas and vapour. The residual, PSA-containing mixture is led through at least one among a plurality of cooled solid separators to separate solid PSA, which is then periodically liquefied again. A second PSA-rich stream is thus withdrawn from the solid separators. The amount per unit in time ratio between the first and second streams ranges from 1:5 to 2:1. The first stream is led at temperatures from 250 to 300  DEG C through a first dwelling vessel, in which it is subjected under stirring to a preliminary thermal treatment for at least 3 hours. The second, PSA-rich stream is purified by distillation together with the first, thermally pre-treated stream, bypassing the first dwelling vessel.
