What is Gas Purification?
Gas cleaning, or purification, is the process in which exhaust streams from manufacturing processes and drilling are processed, the unwanted contaminates in the stream our removed, and a majority mixture of target gases such as Methane, Carbon Dioxide, and / or Hydrogen remain. These remaining gases are then further purified to remove minority gases such as Nitrogen, Water, and / or Oxygen and readied for resale or use.
GCES offers gas purification services to a number of industries. The process GCES uses begins when pressurized feed gas is pushed through a series of upstream plant filtering equipment packages to remove contaminants which protects the membrane fiber or filter media from liquids, certain chemicals, and particulates.
For a membrane package or a filter media, temperature and pressure control is critical. Membranes separate the gas specific rich permeate and lean residue. The separation of permeate and residual gas is driven by the partial pressure difference between the feed gas and permeate gas as well as the advanced polymer material. Separation through a specialized adsorption media creates different challenges in trying to achieve different overall performance characteristics.

Why Purify Gas?
Waste-to-energy projects are gaining popularity around the world. Gas purification offers a wide variety of benefits for a facility or company. With so much focus on renewable energy and climate change and the role industry plays, a gas cleaning project with GCES shows environmental initiative. “Green” projects like this can bring positive press and attention to otherwise scrutinized industries, such as mining, landfills, and other traditional “waste” streams. In addition to the corporate social responsibility aspect, purifying gas can bring in additional revenue. This can be accomplished a few different ways. Tax incentives and government sponsored project loans are available to many facilities that are collecting and purifying hydrogen, methane, or carbon dioxide from waste streams. Gas purifying can also help facilities enter the carbon market.
Types of Gas Purification Projects:
Carbon Dioxide: Carbon Liquefaction takes place when carbon dioxide is purified and liquefied for other applications. There are many uses for CO2 and many trading markets and tax incentives that encourage its use. The three most common sources of revenue for facilities capturing and liquefying carbon dioxide include:
- Beneficial use such as in the food and beverage industry
- Carbon Trading
- Tax Incentives
Hydrogen: Opportunities for hydrogen capture applications are available in nearly any application with methane heavy processes, such as coal mining, landfills, food waste digestion, solid waste treatment, water treatment, feed stocks, rendering, and more. Captured hydrogen can be used for many different applications including lifting, fuels, chemicals, metals, and medical applications.
Renewable Natural Gas (RNG): The RNG created by other manufacturing and waste treatment processes is incredibly valuable because it can be used interchangeably with natural gas for heat, electricity, and even transportation. Many new state and federal programs and tax credits have popped up over the last 3 years, showing a growing interest in RNG projects. Most states have programs that incentivize utility providers to purchase and use RNG in place of traditional natural gas leading to a rather substantial demand.
