A process for producing methanol, wherein a make-up gas stream from a reformer unit is admixed with a hydrogen-containing stream from a hydrogen recovery stage to obtain a hydrogen-rich synthesis gas, which is combined with a residual gas stream and the combined stream is passed through a bed of a methanol synthesis catalyst at elevated pressure and elevated temperature to obtain a product stream comprising methanol and the residual gas stream and wherein the product stream is cooled to remove methanol from the residual gas stream. Wherein a portion of the residual gas stream is removed as a purge gas stream and a portion of the hydrogen-rich synthesis gas stream is removed and combined with the purge gas stream to obtain a mixed synthesis gas stream and the mixed synthesis gas stream is sent to the hydrogen recovery stage to produce the hydrogen-containing stream.

Thermoplastic polyesters are made by a method in which precondensation is carried in a column whose sections are formed with structured packings and operated at subatmospheric, pressure.
