An electronics plant uses an adsorption system to recover solvent from a vent gas stream and prevent volatile organic compound (VOC) emissions. The vent gas flow rate is 20 m3 /s of dry air at 293 K, 1.5 atm. The initial solvent loading is 1.5 mol%, which must be reduced to 20 ppm to comply with emissions permits. Activated carbon is used as adsorbent, and has a capacity of 20 mol/kg of adsorbent and a heat of adsorption of 8 kcal/mol solvent. The sorbent can be regenerated by raising the temperature to 363 K. Design a suitable TSA system for this process. Estimate the amount of adsorbent needed, the vessel volumes, and the minimum regenerate heat requirement for your design. The activated carbon adsorbent has average bulk density 120 kg/m3 and heat capacity 0.7 J/g.°C. The solvent flammability limits in air are 2.5 to 12.0 vol% at 293 K and 1.2 to 16.0 vol% at 363 K.
A crystallization process requires operation at -5º C. The refrigeration system can reject heat to cooling water that is available at 35º C. If a single refrigeration cycle has an efficiency of 60% of Carnot cycle performance then estimate the cos..

Reconsider the Methanol Water Distillation. If the feed stream contains 60 mol % methanol, reevaluate reflux ratio, number of stages required, and the column diameter.
Acetylene is formed as a by-product in the manufacture of ethylene. It is removed by selective hydrogenation using noble metal catalysts (see, for example, US 7,453,017). A particular catalyst achieves 90% acetylene saturation with 50% hydrogen se..
The composition of a gas derived by the gasification of coal is, volume percentage: carbon dioxide 4, carbon monoxide 16, hydrogen 50, methane 15, ethane 3, benzene 2, balance nitrogen. If the gas is burnt in a furnace with 20% excess air, calcula..
