Synthesis gas is a mixture of CO, CO2 and H2 produced from various sources through steam reforming, partial oxidation, CO2 reforming or autothermal reforming [Løvik 2001]. The synthesis gas reacts to produce methanol in the second section, and methanol is purified to the desired purity in the tail-end of the plant. The capital cost of large scale methanol plants is Exercise 4 – Methanol Synthesis In a methanol plant natural gas is reformed into synthesis gas ( and ) which reacts to methanol and is distilled to high purity. This exercise will be limited to the reaction section, taking a closer look on the synthesis loop. Question 1 – Topology regarding synthesis gas in retrofitting the Lurgi process for low-pressure crude methanol production (without purification) from biogas. Raw material (natural gas or biogas) is first desulphurized (D101) and then heated up in a steam reformer (REA-1), where synthesis gas is produced from raw material (natural gas or biogas) and steam, at 825 oC Most methanol is made from syngas.

Synthesis takes place at a pressure of about 1400 pounds per square inch, about 95 times atmospheric pressure. Methanol Synthesis also requires the use of a Catalyst and the reaction takes place at a feed temperature that allows the best conditions for optimum production. synthesis gas consisting of CO, CO 2, H 2 O and H 2. This is usually accomplished by the catalytic reforming of feed such as SMR1, POX2, ATR3 and Combined Reforming. The second step is the catalytic synthesis of methanol from the synthesis gas [1].

•Thus, QAFAC's Methanol Plant Many methanol production bases are situated overseas in natural gas fields, from where methanol is transported to consumers, includ- ing Japan. Recently, more Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon Methanol is produced from synthesis gas (carbon monoxide and hydrogen), itself derived from oil,coal or, increasingly, biomass. It may become central to the 1 Nov 2020 methanol is generally about twice that of a plant using methane or light petroleum fractions as feedstock (5-7). USES OF SYNTHESIS GAS. Methanol is produced from syngas typically derived from coal or natural gas. Methanol in turn serves as a raw material to a whole host of industrially important Topsoe-designed methanol production plants combine advanced syngas generation and syngas-to-methanol processes with high-activity methanol production The synthesis gas is then converted to methanol via SE-MeOH process.
Catalytic methanol synthesis from syngas is a high-temperature, high-pressure exothermic reaction. The temperature and pressure can be controlled at 250–300°C and 50–150 bar (5–15 MPa), respectively. The chemistry of methanol synthesis is as follows. Common byproducts of methanol formation are: CH 4, methyl formate, higher alcohols and acetone
• production of synthesis gas, • conversion of synthesis gas to methanol and • distillation of the reactor effluent to obtain the required product specifications.
