PRECISION Methanol technology

Our PRECISION Methanol process is based on autothermal reforming, and it is the best solution for lighter feedstocks with low levels of CO2 and inert gases. It achieves high natural gas efficiency without the need to import H2, delivering low OPEX, economy of scale and the fastest pay-back time for medium to large methanol capacities.

Waste to methanol

Waste is a source of valuable carbon and hydrogen that can be transformed into methanol. This reduces the amount of waste destined to landfill and incineration and replaces natural gas and coal-based feedstocks, enabling the production of more sustainable fuels and chemicals with a lower carbon footprint.

CO2 to methanol

Methanol produced using electrolytic hydrogen is an attractive alternative and potentially carbon neutral fuel. It can be directly used as a road and maritime transportation fuel or as a low carbon intensity intermediate to produce Sustainable Aviation Fuel (SAF) or green gasoline.
