Abstract Coal gasification and coking to methanol (GCtM) is a newly developed and industrialized process in China. However, in the early stages, the idea of integration hardly applied to this process. To improve the degree of integration, this paper developed a coupling process of coproducing methanol and ethylene glycol.
Methanoltogasoline process2 In the MTG process, the conversion of methanol to hydrocarbons and water is virtually complete and essentially stoichiometric. The reaction is exothermic with a heat of reaction of approximately MJ/kg of methanol with an adiabatic temperature rise of approximately 600 ˚C. In the fixed bed process

In the process simulation, two reactors were employed due to low conversion of the CO 2 hydrogenation reaction. Figure 1 represents the process flow diagram of methanol production via CO 2 hydrogenation (Wiesberg et al., 2016).In this process, the feed of 1,000 kmoles per hour of carbon dioxide at 40°C and 20 bar was mixed with the 3,000 kmoles per hour of hydrogen (at the same conditions).
In an effort to meet energy and chemical demand in Indonesia, the coal based methanol (CtM) project is developed, aiming to produce tones/year AA Grade Methanol from LRC with moisture content of 33% planned to be used as a feedstock to Ethanol Plant. In order to provide suitable and better process design during detailed feasibility ...
Consequently, the cost of ton/hr methanol production was reduced, from 1063 /ton to /ton, by employing SOE and optimizing the process flowsheet (by considering seven different ...
The production of methanol from coal holds unique potential as a means of using a technology which is commercially available for producing a versatile fuel that can be used in automobiles, electric power plants, gas turbines, and fuel cells, A methanolfromcoal process involves gasification of coal to produce synthesis gas (carbon monoxide and ...
The coaltomethanol process can be divided into four major cost areas: coal purchase, coal gasification, gas preparation, and methanol synthesis. The contribution to the plantgate cost was estimated for each area except for coal purchase by dividing the plant capital and operating costs among the areas and calculating a product price for each.
A coalbased coproduction process of liquefied natural gas (LNG) and methanol (CTLNGM) is developed and key units are simulated in this paper. The goal is to find improvements of the lowearning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a lowmargin, single synthesis natural gas (SNG) product. In the CTLNGM process, there are two innovative aspects.
In coaltomethanol or lignitetomethanol plants, coal or lignite is first gasified into synthesis gas (syn gas) by mixing pulverized coal or lignite with an oxidant such as oxygen or steam. The ...

Coaltomethanol (CTM) is the main methanol production process in China. Application of carbon capture and storage (CCS) technology in CTM is a possible way for CO capture and Organic Rankine Cycle (ORC) thermodynamic cycle compression and unit in CTM process.
The liquidphase methanol process, through its superior heat management capabilities, can handle the synthesis gas straight from the generator, as it has a ratio of 1:1 to 1:2 as generated by coal gasifiers (Tijm et al., 2001). However, the ideal ratio H 2 /CO 2 responds to Eq. ().
The process. Methanol is an intermediate for the coaltoolefins (CTO) process and a direct feedstock for the methanoltoolefins (MTO) process. To produce the methanol intermediate for the CTO process, coal gasification produces syngas (carbon monoxide), which is then converted to methanol by traditional technologies.
