Shell and Tube Heat Exchangers Construction Details
Note: Due to rounding, performing the calculations given in the equations below may not return the exact results shown. 8.89 × 10-3 metric tons CO 2 car/truck average × 1/22.5 miles per gallon car/truck average × 1 CO 2, CH 4, and N 2 O/0.993 CO 2 = 4.60 metric tons CO 2 E/vehicle /year.

Some of the various types of heat exchangers are shell and tube, plate coil, pipe coil, bayonet and air finned tube. This paper deals with the shell and tube heat exchanger which is the most commonly used type in the Chemical Processing Industry (CPI), See Figure 1. 112 Figure 1. DISCUSSION Rules for designing and fabricating the pressure containing parts of shell and tube heat exchangers are
1.4.3 Emissions3-4 The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide (SO2), and particulate matter (PM).

Nitrogen - Thermophysical Properties
The gas produced in boil off is traditionally diverted to the boilers and used as a fuel for the vessel. Before this gas is used in the boilers, it must be warmed up to roughly 20 °C by using the gas heaters. The gas is either fed into the boiler by tank pressure or it is increased in pressure by the LD [clarification needed] compressors.
A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure. Components typically affected: Furnace wall tubes,
