MtSynfuels®: Lurgi's New Route to Synthetic Fuels
Ahlers, Bernd (Lurgi AG) | Liebner, Waldemar (Lurgi AG)
ABSTRACT Only about 5% of the global annual gas consumption is used for the conversion to ammonia, methanol and some other chemicals. The proven natural gas reserves to production ratio, i.e. lifetime is about 100years for Africa and 260years for the Middle East. Taking into account the total amount of gas being flared world-wide which is corresponding to the feedstock of 74 Mega-Methanol plants of 5000 t/d each, there is a real challenge regarding large-scale monetisation of these gas sources in accordance with environmental aspects. The technology development in the conversion of gas has to consider easily transportable valuable products. Also it must cover the logistics for bringing these products to the market. What first comes to mind with GTL is Fischer-Tropsch (FT), the classic route from coal or natural gas to transportation fuels (synfuels). Being one of the pioneers of FT Lurgi today promotes both, a methanol-based synfuels technology and FT. Since Lurgi introduced its new groundbreaking MegaMethanol process for plants with a production of 5,000 tons of methanol per day and more, methanol will be available at a constant low price in the foreseeable future. The first such plant started up in fall 2004 and operates smoothly at 100%+ capacity since early October. This development has an enormous impact on down-stream technologies for the conversion of methanol to more valuable products. On the other hand the development of FT technologies also made good progress. Here, Lurgi joined forces with an oil company and a synfuels producer to develop and bring to market a highly competitive FT-process. The presentation will give a comparison of the methanol-based technology for the production of synfuels, named MtSynfuels with this modern FT-process. Advantages and preferred applications of both routes will be demonstrated. CONTENTS Lurgi MegaMethanol®: Basis for More Valuable Products Lurgi's New Route to Transportation Fuels: MtSynfuels® Lurgi's Experiences in Fischer-Tropsch Technologies DME - the "Better Diesel" Conclusions (Figure in full paper) The very first step is the conversion to synthesis gas in a highly efficient single-train process for truly large capacities, namely MegaSyn which can be described as "optimised reforming". Hydrogen, ammonia and Fischer-Tropsch products can be derived from this syngas at lowest cost. This cost advantage is carried over to MegaMethanol and even boosted there by way of integration and cost reduction due to design and plant size of MegaMethanol plants. The term MegaMethanol refers to plants with a capacity of more than one million metric tons per year, the actual "standard" size being 1.7*10 t/a (equivalent to 5,000 t/d). Since Lurgi introduced its new groundbreaking MegaMethanol process for plants, methanol will be available at a constant low price in the foreseeable future. This development has an enormous impact on downstream technologies for the conversion of methanol to more valuable products. The first derivative of methanol in this context is DME, which has a high potential as alternative to conventional diesel fuel, as feed gas for gas turbines in power generation and as supplement to LPG.

Gas to Propylene: Report On Commercialisation By Lurgi

Abstract: Only about 5 % of the global annual gas consumption is used for the conversion to ammonia, methanol and some other chemicals. The proven natural gas reserves to production ratio, i.e. lifetime is about 100 years for Africa and 260 years for the Middle East. Taking into account the total amount of gas being flared world-wide which is corresponding to the feedstock of 74 Mega-Methanol plants of 5000 t/d each, there is a real challenge regarding large-scale monetisation of these gas sources in accordance with environmental aspects. The technology development in the conversion of gas has to consider easily transportable valuable products. Also it must cover the logistics for bringing these products to the market. What first comes to mind with GTL is Fischer-Tropsch, the classic route from coal or natural gas to transportation fuels (synfuels). Lurgi on the other hand promotes methanol-based technologies for upgrading of natural gas to value-added products. Since Lurgi introduced its new groundbreaking MegaMethanol process for plants with a production of 5,000 tons of methanol per day and more, methanol will be available at a constant low price in the foreseeable future. The first such plant started up in fall 2004 and operates smoothly at 100%+ capacity since early October. This development has an enormous impact on down-stream technologies for the conversion of methanol to more valuable products. The first derivative of methanol in this context is DME which has a high potential as alternative to conventional diesel fuel and as feedgas for gas turbines in power generation. The next step is the use of methanol as feedstock for the production of olefins which is one of the most promising new applications. Lurgi's new Methanol-to-Propylene (MTP) process presents a simple, cost-effective and highly selective technology. Lurgi reported about these developments at the 17th WPC in Rio de Janeiro. Now, two years later we can present the first steps into commercialisation - especially of the gas to propylene route. Natural Gas in the 21 Century: A Key Feedstock for (Petro-) Chemicals The total proven gas reserves amount to approx. 180 trillion cubic meters world-wide which translates into a gas reserve-to-production ratio, i.e. a gas reserve lifetime of 70 years. Furthermore, estimated additional gas reserves will cover a lifetime of 65 years more. Compared with the reserve lifetime of 41 years for petroleum and 230 years for coal, there is no doubt that natural gas will be a key fuel component in the 21 century. However, a considerable portion of this reserve is wasted yearly: more than 80 billion cubic metres of natural gas and oil associated gas are flared for technical reasons or for lack of markets. This explains the main incentive for engineers and environmentalists as well to come up with novel ideas for the utilisation of this gas. Existing technologies for natural gas conversion are based on the conversion to synthesis gas (or short: "syngas", a mixture of carbon monoxide, CO, and hydrogen, H2) and from there to hydrogen and ammonia, Fischer-Tropsch products as well as methanol and DME.
