Chemical analysis of natural gas stream
As per proposed feed composition of 6%wt Carbon dioxide, 14%wt Methane, 10%wt Ethane, 10%wt Propane, 4%wt Hydrogen, 56%wt Diethanolamine, the hazardous effects as well as selected physical properties together with hazards categories are shown in the following tables.
- All chemicals are reported in danger, except carbon dioxide.
- With respect to physical hazards, methane, ethane, propane and hydrogen should be stored with caution since they may easily cause fires.
- Carbon dioxide is used as food additives, for example in carbonated beverages, fire extinguishers, dry ice, and propellants. Carbon dioxide is however also a member of greenhouse gas.
- Methane is used as chemical intermediate in making other chemicals and as a constituent of the fuel, natural gas
- Ethane is used in the manufacture of chlorinated derivatives; as refrigerant in some two-stage refrigeration systems where relatively low temperatures are produced; as fuel gas.
- Propane is a component of liquid petroleum gas for commercial and industrial usage; feedstock in thermal cracking processes used to manufacture ethylene and propylene; refrigerant in chemical refining and gas processing operations; fuel in welding and cutting operations.
- Hydrogen is used in welding (oxy-hydrogen and autogenous), petroleum refining, and as a coolant; used to hydrogenate oils and other organic compounds and to reduce metal oxides.
- Diethanolamine is used in cutting oils, soaps, shampoos, cleaners, polishers, cosmetics, and pharmaceuticals. It is also used as an intermediate in the rubber chemicals industry, as a humectant and softening agent, and as an emulsifier and dispersing agent in various agricultural chemicals.
