Suited to large-scale production, Lurgi MegaMethanol™ converts syngas derived from any carbonaceous feedstock into raw methanol using a two-step reactor process. This reliable technology offers minimized production costs at maximized capacity.
Large capacity. Reduced costs.
Depending on customer needs, the Lurgi MegaMethanol™ unit may feature integrated syngas generation from natural gas or it may be downstream of a gasification unit. In both cases, the feedstock (natural gas or syngas) is passed over a copper catalyst in a two-step synthesis process involving water-cooled and then gas-cooled reactors. The two stage reaction process allows low recycle ratios leading to reduced equipment size and therefore large single train capacities. The resulting raw methanol product is then distilled further to meet customers' required specifications (e.g.: International Methanol Producers and Consumers Association, United States Federal Grade Acrylic Acid).
Any unconverted syngas is recycled back into the synthesis loop to increase yield and improve carbon efficiency.
Lurgi MegaMethanol™ offers very low production costs thanks to the unit's high energy integration and low recycle ratio in the synthesis loop. The process is particularly well-suited to customers with methanol production needs of more than one million tons per annum. The most recent GigaMethanol design from Air Liquide Engineering & Construction is capable of producing as much as 10 000 tons per day in a single train.
