Methanol (also known as wood alcohol and methyl alcohol) is used as a raw material in the manufacture of formaldehyde, acetic acid, and a number of other chemicals. One way it can be synthesized is by reacting carbon dioxide and hydrogen:
CO2 + 3H2?CH3OH + H2O
The fresh feed to a methanol synthesis process contains hydrogen, carbon dioxide and 0.4 mole% inerts. The reactor effluent passes to a condenser that removes essentially all of the methanol and water formed and none of the reactants or products. The latter substances are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. The feed to the reactor (not fresh feed to the process) contains 28 mole% CO2, 70 mole% H2, and 2 mole% inerts. The single pass conversion of hydrogen is 60%. Calculate the molar flow rates and molar compositions of the fresh feed, the total feed to the reactor, the recycle stream and the purge stream for a methanol production rate of 110 kmol/h.

A 384.0 g/hr stream of liquid methyl alcohol, also called
methanol, (CH3OH) at 7.60 atm and 10.0°C was held at
constant pressure, vaporized and brought to 564.0°C. At what rate
must heat be supplied to this system? Assume that methyl alcohol
vapor behaves ideally for the temperature range and pressure
given.

The Wood Spirits Company produces two products long dash
—methanol (wood alcohol) and turpentine —by a joint process. Joint
costs amount to $121,000 per batch of output. Each batch
totals 11,500 gallons: 25% methanol and 75%
turpentine. Both products are processed further without gain or
loss in volume. Separable processing costs are methanol, $2 per
gallon, and turpentine, $1 per gallon. Methanol sells
for $ 20 per gallon. Turpentine sells for $15 per gallon.

Methanol is the simplest alcohol and it is used as a fuel in
race cars and is a potential replacement for gasoline. Methanol can
be manufactured by combination of gaseous carbon monoxide and
hydrogen – if 68.5 Kg of carbon monoxide are reacted with 8.6 Kg of
hydrogen, calculate the theoretical yield of methanol. If 3.57* 104
g of methanol are actually produced, what is the percent yield of
methanol?

Company A produces two products—methanol (wood alcohol) and
turpentine -- in a joint process. Joint costs amount to $124,200
per batch of output. Each batch totals 13,500 gallons: 25% methanol
and 75% turpentine. Both products are processed further without
gain or loss in volume. Separable processing costs are methanol,
$11 per gallon; turpentine, $3 per gallon. Methanol sells for $22
per gallon. Turpentine sells for $16 per gallon. The company has
discovered an additional process by which the methanol (wood...

A) An aqueous solution of methyl alcohol is made by transfering
2.39 mL of liquid methyl alcohol to a 100. mL volumetric flask, and
then adding enough water to fill the flask to the mark. What is the
volume/volume percentage of methyl alcohol in the solution?
B) An aqueous solution of acetone is made by
transfering 7.17 mL of liquid
acetone to a 100. mL volumetric
flask, and then adding enough water to fill the flask to the mark.

Methanol and ethanol are both oxidized by alcohol dehydrogenase
(ADH). Methanol is poisonous because it is oxidized by ADH to form
the highly toxic compound formaldehyde. The adult body has 40 L of
water, throughout which these alcohols are rapidly and uniformly
distributed. The densities of both alcohols are 0.79 g/mL. The Km
of ADH for ethanol is 1.0x10-3 M, and for methanol the Km is
1.0x10-2 M. The molecular mass of methanol is 32 g/mol and that of
ethanol...

An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in
an excess of O2(g) and yields 0.380 g CO2(g) (carbon dioxide).
Set up two algebraic equations, one expressing the mass of
carbon dioxide produced in terms of each reagent and the other
expressing the mass of sample burned in terms of each reagent.
What is the mass of methyl alcohol (CH3OH) in the sample?
