Systems and methods for processing crude methanol are disclosed. A crude methanol stream, comprising methanol and paraffin wax, is produced from syngas (carbon monoxide, carbon dioxide, and hydrogen). The crude methanol stream is cooled to form a partially condensed crude methanol stream, which is further separated in a vapor-liquid separator to form a liquid stream and a gas stream. The liquid stream is further cooled in a dewaxing unit to remove paraffin wax. The dewaxing unit includes two or more cooling units arranged in parallel such that when one of the cooling units is offline for cleaning, the methanol system does not need to be shut down.
