What is a Methanol?

Methanol, also known as methyl alcohol, wood alcoholwood naphtha or wood spirits, is a chemical with the formula CH3OH. Methanol acquired the name "wood alcohol" because it was once produced chiefly as a byproduct of the destructive distillation of wood. Modern methanol is produced in a catalytic industrial process directly from carbon monoxidecarbon dioxide, and hydrogen.Methanol is the simplest alcohol, and is a light, volatile, colorless, flammable liquid with a distinctive odor very similar to that of ethanol.

What is a Methanol plant?

Methanol (CH3OH) is produced from synthesis gas, natural gas or other hydrocarbons utilizing flexible PPE designed and fabricated equipment.PPE has designed, fabricated and installed methanol plants utilizing a variety of feedstocks including conventional sources such as natural gas and syngas and non-conventional sources such as biowaste.PPE offers a range of equipment options to generate methanol designed for your specific application. We can provide skid-mounted modular plants or large-scale on-site plants.PPE offers a range of equipment options to generate methanol designed for your specific application.

Process of Methonal making plant?

The Uhde low-pressure synthesis loop consists of a recycle compressor, feed/effluent exchanger, methanol reactor, final cooler, and crude methanol separator. The crude methanol, which is condensed downstream of the methanol reactor, is separated from unreacted gas in the separator and routed via an expansion drum to the crude methanol distillation. Water and minor quantities of by-products formed in the synthesis are removed by an energy saving Uhde-designed three-column distillation system.

Typical consumption figures (feed plus fuel) range from 29 to 33 GJ per metric ton of methanol produced. Waste heat from the syngas unit that fed this facility was being used in the Methanol Plant. Additional steam for heating will need to be made available if the plant is not linked to a syngas unit as before.Uhde claims that the simple addition of a pre-reactor will increase this unit’s capacity by 20%.

Ethylene Plant in Gelsenkirchen, Germany

Major Equipment used

Compressor:  Built in 1995.  This centrifugal compressor operates with make-up gas (MUG) on one side and recycle (REC) gas on the other side.  It compresses 50,000 Nm3/hr of make-up gas from 19 bar at 44 °C to 44 bar at 117 °C.  It compresses 285,000 Nm3/hr of recycle gas from 37 bar at 37 °C to 42 bar at 49 °C.  It has a 4,000 kW electric drive motor.

Activated Carbon Reactor:  2.2 m diameter and 9.4 m tall.  Constructed of carbon steel.  Rated for 54 bar at 160 °C.   Fixed bed with 5 m3 of activated carbon and 19 m3 of Al2O catalyst type R 10/20.

Deoxo Reactor:  2.2 m diameter and 4.3 m tall.  Constructed of carbon steel with stainless steel lining.  Rated for 54 bar at 230 °C.  The deoxo reactor uses BASF Puristar palladium-based catalyst type RO-20/47 (catalyst has been removed and reclaimed).

Guard Bed Reactor:  2.2 m diameter and 7.7 m tall.  Constructed of carbon steel.  Rated for 54 bar at 250 °C.  The guard bed reactor utilizes a zinc oxide-based catalyst on top of 22 m3 of a BASF Puristar copper-based catalyst type R3-15. 

Methanol Reactor:  4.0 m diameter and 12.5 m tall.  Constructed of carbon steel shell with stainless steel tubes rated for 54 bar at 270 °C.  The tubes are packed with a copper-based BASF catalyst type S 3-86.  The temperature in the catalyst tubes is monitored at the top and bottom by 12 thermocouples.  The tube side operates at 45 bar and 250 °C.  The shell side produces 36 – 43 bar steam.

Crude Methanol Storage Tank:  3.8 m diameter by 21 m tall.  It holds 250 m3 and is constructed of carbon steel.  It is rated for 0.5 bar and 70 °C.

Topping Column:  3.5 m diameter at the bottom and 1.2 m diameter at the top.  It is 33.5 m tall with 48 sieve trays.  Both the column and the trays are constructed of carbon steel.  The column operates at 3.5 bar and 130 °C.

Refining Column 1:  2.3 m diameter and 40.4 m tall with 73 sieve trays.  Both the column and the trays are constructed of carbon steel.  The column operates at 6.5 bar and 250 °C.

Refining Column 2:  3.0 m diameter and 39.5 m tall with 68 sieve trays.  Both the column and the trays are constructed of carbon steel.  The column operates at 0.25 bar and 110 °C.

Pure Methanol Storage Tanks (2):  2.8 m diameter by 22 m tall.  They hold 129 m3 and are constructed of carbon steel.  They operate at 0.25 bar and 35 °C.



Market Analysis of  Methonal Making plant

CROP plants sprayed with diluted methanol, or wood alcohol, showed significantly greater yields while requiring less water than a comparison group of plants, two researchers say.Methanol spraying, however, does not boost the growthof all plants. Corn, sorghum and the weeds, Johnson and Bermuda grass, were unaffected. In addition, because the methanol appears effective only when sprayed under very bright light, winter crops and crops grown in less sunny areas are unlikely to benefit.Normally when plants use sunlight to make sugars during photosynthesis they use carbon dioxide as their source of carbon. But in the early 1980's, Dr. Nonrandom and Dr. Benson found that algae, when given methanol as a carbon source, could grow twice as fast, producing twice as many carbon-containing molecules like sugar and proteins.Market value of methanol making plant is very high.Its a good obtains to start a business in methanol making plant.
