A method for the preparation of methanol by conversion of a mixture of fresh methanol synthesis gas and unconverted methanol synthesis separated from produced methanol in a low pressure separator and recycled and admixed to the fresh synthesis gas upstream the suction side of a make-up gas compressor.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

There is provided systems and methods for aggregating and enhancing the initial materials produced from the conversion of flare gas at a flare gas source. In an embodiment the flare gas source is a hydrocarbon wellhead and the initial material is methanol and the end product is grade methanol.
