Agas stream containing 40.0 mole% hydrogen, 35.0% carbon monoxide, 20.0% carbon dioxide, and 5.0% methane is cooled from 1000oc to 10oc at a constant absolute pressure of 35 atm. gas enters the cooler at 120 m3/min and, upon leaving the cooler, is fed to an absorber where it is contacted with refrigerated liquid methanol that enters the absorber at a molar flow rate 1.2 times that of the inlet gas and at -15oc. essentially all of the co2 is absorbed, as is 98% of the methane and an inconsequential amount of the other components of the feed gas. the gas leaving the absorber is saturated with methanol at -12oc and is fed to a reactor for further processing.
(a) calculate the volumetric flow rate of methanol entering the absorber (m3/min) and the molar flow rate of methanol in the gas leaving the absorber. do not assume ideal-gas behavior when doing pvt calculations.
(b) list and explain at least three hazards associated with the system described.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
