—the gas is cooled to extreme temperatures, allowing ethane, propane, and butane to be separated. These liquids are the lifeblood of the petrochemical industry, serving as feedstocks for plastics and chemicals. Dehydration and Mercury Removal
“We used to design for the average gas composition,” says a Gulf Coast plant manager who spoke on condition of anonymity. “Now, with shale depletion and the influx of renewable natural gas (RNG) from landfills, the feed changes hourly. The Handbook’s new ‘Adaptive Heat Exchanger Network’ chapter shows how to recover 97% of exergy—waste cold energy—and use it to fractionate the next batch.”

The gas processing industry faces several challenges, including: gas processing handbook exclusive
above the inlet gas dew point and utilizing mechanical and carbon filtration.
Deploying low-pressure flooded screw compressors allows operators to capture these low-pressure flash gases, compress them, and re-inject them into the plant inlet header. This turns a hazardous emissions source into sellable product stream.
Once the gas is sweet and dry, the focus shifts to the recovery of Natural Gas Liquids (NGLs). The Gas Processing Handbook delineates the technologies based on the required recovery rates and the composition of the inlet gas. —the gas is cooled to extreme temperatures, allowing

Replacing gas-fired turbines with EMDs for large residue compressors eliminates point-source emissions when tied to a clean power grid. “Now, with shale depletion and the influx of

Market dynamics frequently require plants to switch from ethane recovery to ethane rejection (leaving ethane in the residue gas stream). Doing this efficiently without shutting down the facility requires a highly flexible piping and control philosophy.
