This book discusses the full aspects concerning the Petroleum Refinery starting from its history reaching a plant design for the products refinery processes and naphtha processing with the help of an industrial simulation programs such as Aspen HYSYS. These decisions have to take into account uncertainties and constraints in factors such as the source and availability of raw material, production and distribution costs and expected market demand. These factors and others forced petroleum companies for a greater need in the strategic planning optimization and sensitivity analysis in order to make decisions that satisfy conflicting multiobjective goals of maximizing expected profit while simultaneously minimizing risk. It is facing a challenging task to remain competitive in a globalized market, the fluctuating demand for petroleum products and the current situation of fluctuating high petroleum crude oil prices is a demonstration that markets and industries throughout the world are impacted by the uncertainty and volatility of the petroleum industry. In the recent years, petroleum industry has grown increasingly complex as a result of tighter competition, stricter environmental regulations and lower-margin profits. The program calculated Sulfuric Acid (H2SO4) Dew Point Temperature = 178.9587 FĪCID5C.Petroleum industry has a major share in the world energy and industrial markets. Percent Volume of Sulfuric Acid in the Wet Flue Gas: 0.000000544955 %ģ. Percent Volume of Water Vapor in the Wet Flue Gas: 17.7198 %Ģ. The following data came from the combustion analysis:ġ. The Natural Gas hasĠ.000337 % Sulfur on a volume basis and it is assumed that 2.0 % of the SO2 is converted to Is 29.9210 in Hg and the Total Flue Gas Pressure is 29.9210 in Hg. In this particular example the fuel is Standard Natural Gas consumed at 100,000 Btu/hr usingĬombustion air at 70 F, 35% Relative Humidity at 10 % Excess Air. With the above data the program calculates the Partial Pressure of the Water Vapor (mmHg)Īnd the Partial Pressure of the Acid Gas (mmHg) which is used to calculate the Dew Point Temperature.Įxample Analysis for Sulfuric Acid (H 2SO 4) Dew Point Temperature This computer program ACID5CĬalculates the dew point temperature for the following Acid Gases: Some of these furnaces did not have stainless steel heat exchangers that could stand up to the Sulfuric Acid. This occurred in the 1990's with some of the early versions of High Efficiency Condensing Natural Gas Furnaces that failed due to corrosion of the heat exchanger caused by theįormation of Sulfuric Acid. Gas temperature, however to low of an exit temperature could result in the condensation of Acid Gases that could corrode metallic surfaces in contact with those acids. Thermal efficiency of combustion systems is increased with the reduction in the exit Flue Water Vapor Pressure From -148 F to 705.298 FĪcid Dew Point Temperature for 5 Typical Acid Gases.Viscosity of Wet Air Used in Air Pressure Drop Analysis.Psychrometrics of Air & Water Vapor Mixtures.Insulated Pipe or Flat Surface Heat Loss or Gain.Ductwork Heat Loss or Heat Gain & Condensation.Building Water Vapor Transmission & Condensation.Electricity Generation & Estimation of Levelized Cost.Air Contaminant Problem Solving & Indoor Air Quality.
