Natural Gas Liquids

What are Natural Gas Liquids?

Natural Gas Liquids also referred to as NGL or NGLs, are those hydrocarbons in natural gas that are separated from the gas as liquids through the process of absorption, condensation, adsorption, or other methods in gas processing or cycling plants. Typically, these liquids consist of propane and heavier hydrocarbons and are commonly referred to as lease condensate, natural gasoline, and liquefied petroleum gas.

Natural Gas Liquids include natural gas plant liquids (primarily ethane, propane, butane, isobutane, and lease condensate (primarily pentanes produced from natural gas at lease separators and field facilities.

We have interest in the Midstream Oil and Gas, Gas Liquefaction, Liquefied Natural Gas, NGL Recovery and Stranded Gas / Gas to Power acquisitions.

Clean Power Generation

Running on "green fuel" such as Biomethane, B100 Biodiesel, Synthesis Gas or natural gas, our CHP Systems are the greenest "clean power generation" systems available.

With Natural Gas at approximately $4.00/mmbtu, our Clean Power CHP Systems  generate power for about $0.04 / kWh (fuel cost).

With operations & maintenance added, that's  about 5.5 cents /kWh - or approximately 50% - 60% less than what most commercial customers are paying, on average, for their electricity.

CHP Systems
(Cogeneration and Trigeneration) Plants 
Have Very  High Efficiencies, Low Fuel Costs & Low Emissions

The CHP System below is rated at 900 kW with a 
heat rate of 4100 btu/kW & system efficiency of 92%.

The CHP System below features: (2) Natural Gas Engines @ 450 kW each 
on one skid with optional Selective Catalytic Reduction system 
which removes Nitrogen Oxides to "non-detect."



A CHP System may be the best solution for your company's economic and environmental  sustainability as we "upgrade" natural gas to clean power with our clean power generation solutions.  CHP Systems and Dispersed Generation power plants are an ideal solution for data centers, district energy systems electric utilities, electric co-ops, electrical sub-stations, energy service companies, food processing plants, hospitals, military bases and  universities among many others. 

High-efficiency CHP Systems eliminate blackouts, electric grid supply problems and significantly reduce greenhouse gas emissions and hazardous air pollutants associated with electric power generation at central power plants.  Our emissions abatement solutions reduce nitrogen oxides (NOx) to "non-detect" and can be installed and operated in most EPA non-attainment regions!

What is Gas Liquefaction

Gas Liquefaction - also referred to as LNG Liquefaction, is a process that refrigerates Natural Gas until it is condensed into a liquid at close to atmospheric pressure (maximum transport pressure set at around 25 kPa/3.6 psi) by the natural gas to approximately −162 °C (−260 °F) which reduces its volume to 1/600th or its original volume for ease of transportation.

Liquefied Natural Gas or simply "LNG" is natural gas which is primarily methane or CH4 that has been liquefied to reduce its volume. As previously stated, LNG is colorless, odorless, non-toxic and non-corrosive. LNG hazards include flammability, freezing and asphyxia.

Gas Liquefaction takes place at an LNG "terminal" which is typically located at an ocean port where one or more natural gas pipelines deliver natural gas. The natural gas has had the contaminants removed by gas processing and purification, which removes, condensates such as water, dust, helium, mud, oil, CO2, H2S and mercury. The natural gas is then cooled down in stages until it is finally liquefied at -160 degrees C. The Liquefied Natural Gas is stored in cryogenic storage tanks and loaded onto an LNG ship and shipped.

What is NGL Recovery?

Toward the end of the gas processing process and natural gas treating process, wherein the "raw" natural gas (methane or CH4) is readied for sale as "pipeline quality gas," the recovery of the valuable natural gas liquids (NGL) takes place. In many gas processing facilities, a cryogenic plant - which provides low-temperature distillation that recovers the natural gas liquids. The residue gas from the NGL recovery process, is the purified pipeline quality gas that is sold via pipeline and sent so end-users such as LDCs (local distribution companies - or natural gas utility) for distribution via natural gas mains in their cities and markets.

Other NGL recovery methods include an NGL fractionation "train" which typically consists of three distillation towers in a series. The series occurs in the following order:

1. deethanizer
2. depropanizer
3. debutanizer.

The overhead product from the deethanizer is ethane - after which the bottoms flow to the depropanizer. The overhead product from the depropanizer is propane and the bottoms then flow to the debutanizer. The overhead product from the debutanizer is a mixture of normal butane and iso-butane. The bottoms products are a C5+ mixture. Most cryogenic plants, however, do not include fractionation due to economic reasons. Therefore the NGL stream is then transported as a mixed product to separate, standalone fractionation plants that are located near refineries or chemical plants that need these NGLs feedstock.

“spending hundreds and hundreds and hundreds of billions of dollars every year for oil, much of it from the Middle East, is just about the single stupidest thing that modern society could possibly do.  It’s very difficult to think of anything more idiotic than that.” 
~ R. James Woolsey, Jr., former Director of the CIA

Price of Addiction
to Foreign Oil

According to R. James Woolsey, for Director of the Central Intelligence Agency, “The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems — they are aspects of a single problem, the West’s dependence on oil.”
