Today — at the threshold to the nineties — there are only 4 plants in the world which produce methanol from coal. Two of them, one in South Africa and the other in the USA, have a low capacity. The other two — one again in the USA, the other in Germany — have outputs of 650 and 1200 tons of methanol per day. One of the reasons why only less than 4% of world methanol production are derived from coal is the fact that coal-based methanol plants of today’s size require a great deal more capital than natural-gas-based ones. They are also more complex — as shown in this book — and require more personnel and maintenance.
