3. (20) Fire Heater Specification After the reactor feed leaves the heat exchanger, it enters a fire heater. In this unit the stream is further heated from 215°C to 350°C, which requires 4649 kJ/h of heat to be added. To accomplish this, the heat from the combustion of methane gas is used: CH4(2) +2 02(g) → CO2() + 2 H20(2) $ = 10.0 molh The design of this fire heater indicates that the temperature of the flue gas will not...

An adiabatic heat exchanger is one for which no heat is exchanged with the surroundings. All of the heat lost by the hot stream is transferred to the cold stream in this adiabatic process. In a proposed process, propane gas enters a continuous adiabatic heat exchanger at 45 °C and 265 kPa and exits at 255 °C. Superheated steam at 300 °C and 7.0 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at...

Q4/ Toluene gas (CH3) enters a continuous adiabatic heat exchanger at (35°C) and (300 KPa) and exits at (260°C). Superheated steam at (400°C) and (5 bar) enters to exchanger flowing counter currently to a Toluene and exits as a saturated liquid at the same pressure. 1- If (150 mol) of Toluene is fed, draw and label a process flow chart. 2- Calculate the values of inlet-outlet enthalpies. 3- Calculate the volumetric feed ratio of the two streams (m' steam fed/mºtoluene...

9.36 In a nuclear power plant the reactor transfers the heat to a flow of liquid sodium, which in a heat exchanger transfers the heat to boiling water. Saturated vapor steam at 5 MPa exits this heat exchanger and is then superheated to 600°C in an external gas-fired superheater. The steam enters the turbine, which has an extraction at 0.4 MPa to an open FWH, and the condenser pressure is 10 kPa. Determine the heat transfer in the reactor and...

Propane gas enters a continuous adiabatic heat exchanger 240°C. Superheated steam at 300 C and 5 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at the same pressure at 40 C and 250 kPa and exits at Taking flow chart. Include both mass and volumes on your inlet and outlet streams. b. Calculate the specific enthalpy values for the inlet and outlet streams. c. Use an energy balance to calculate the required mass...

Carbon dioxide (CO2) is used for the gas cooled reactor in shell and tube heat exchanger type steam generator (shown in Figure 2). 90000 kg/h entered to the exchanger under pressure and temperature of 4 bar and 500 OC respectively. The steam saturation temperature is 250 oC when the carbon dioxide leave the generator at 3300C. Presume the formed steam is saturated and dry. Using 25 mm inner diameter and 2 mm wall thickness, a copper tube is designed for...

Problem 3 Steam enters a heat exchanger at 0.1 bar with a quality of 0.95 and condensate exits at 0.1 bar and 45'C. Cooling water enters the heat exchanger in a separate stream as a liquid at 20'C and exits as a liquid at 35 C with no changes in pressure. Heat transfer from the outside of the heat exchanger and changes in the kinetic and potential energies of the flowing streams can be ignored. For steady state operation, (a)...

A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...
