Hydrogen (H2) is burned completely with the stoichiometric amount of air during a steady – flow combustion process. If both reactants and the products are maintained at 250C and 1 atm and the water in the products exists in the liquid form, determine the heat transfer from the combustion chamber during this process. What would your answer be if combustion were achieved with 80% excess air

Solve the following exercise: There is a solution of organic colloids, which is concentrated in water from 12% to 47% in a simple effect evaporator. The water vapor is at a pressure of 150 kPa and the pressure in the evaporator is 13.60 kPa. The feed rate to the evaporator is 12300 kg/h. The overall heat transfer coefficient is taken to be 1600 W/m2 °C. The solution has negligible boiling point elevation. Calculate the heating surface required if the feed temperature is 27.3 °C, plus the steam consumption. The feed heat capacity is 3.2 kJ/kg*K. 12300kg/h Tf 12%solids Ts Pman=150kPa F s T1 P1=13.60 kPa S L 47% solids

Pure CO is mixed with 100 percent excess air and completely burned at constant pressure. The reactants are originally at 400 K. Determine the heat added or removed if the products leave at 600 K. The standard heat of reaction at 298 K is -282.99 kJ per mol CO burned. The mean specific heats applicable in the temperature range of this problem are 29.10, 29.70, 29.10, and 41.45 J/mol K respectively for CO, O₂, N₂ and CO₂.

Fruit juices at 30 ° C containing 5% total solids were concentrated via a single effect evaporator. The evaporator is operated in a vacuum at an evaporation temperature of 80 ° C, and 90% quality steam is supplied at 169.06 kPa. The desired concentration of the final product is 40% total solids. The rate of concentrated product leaving the evaporator is 2000 kg / hour. The specific heat of fruit juice is 4.05 kJ / (kg ° C), and the concentrated product is 3,175 kJ / (kg ° C). Count a. The required steam rate is = kg / hour. b. Steam economy when the condensate temperature is released at 90 ° C. = (kg of water evaporates / kg of steam)

Basic Principles of Chemical Engineering Question Solve this problem while do not use  ΔĤr 0 and use Heat of Formation and use tables B1 and B2 and B8 from Elementary Principles of Chemical Processes (3rd Edition) book if it is necessary. (I can not send these tables because of image sending limit is just two for Bartleby.) Please solve step by step

You are working for a factory that uses benzene in it process. The effluent flow out of the process is air at a temperature of 138˚C and atmospheric pressure that contains 20,000 ppm of benzene. The flow rate is 0.5 m3/s. If you want to recover 33% of this benzene by condensing it, what temperature should you cool it to?
