Sundyne Pumps and Compressors For Midstream Applications

Natural gas is a naturally occurring hydrocarbon formed by intense heat and pressure under the earth’s surface over millions of years.  It was initially discovered in China in 500 B.C. and first extracted on an industrial scale in New York in 1825.  Over the last several years, the volume of proven reserves has increased substantially, creating new opportunities for upstream and midstream producers.

In addition to providing the feedstocks for chemicals and plastics, natural gas is increasingly becoming the feedstock of choice for power generation.  As developing nations in Asia, Africa and other parts of the globe mature, energy demand is predicted to increase by as much as 45-percent.  Solar, wind, and biofuel renewables are expected to meet about by 5-percent of this new demand - But current forecasts*¹* suggest that up to 40-percent of the world’s new energy demand over the next 20 years will be met by natural gas. (*denote in footer - ¹according to Royal Dutch Shell).

In the United States, gas has surpassed coal as the single biggest source for power generation, and the trend is catching on globally, as most new power plants use gas as a feedstock, for several reasons: 

  • Abundance of supply
  • Favorable economics
  • New efficiencies in LNG processing – enabling global transport
  • Ease of domestic transport via pipeline
  • Environmental efforts to minimize carbon emissions.
  • Gas plants require far less water for cooling purposes than nuclear or coal plants

 

Increasing Demand for Midstream Gas Processing:

Oil and natural gas are often found together in the same reservoir, and different well types (crude, gas, or condensate wells) produce different types of sweet, sour or acid gases.  Processing activities begin at the wellhead by removing water and contaminants, and are continued by midstream companies, which operate pipelines and gathering facilities.

 

Common midstream processing applications include:

  • Amine Treating, to remove acid gas.
  • Molecular Sieve dehydration: Natural Gas condenses to LNG at -260°F (-160°C), and water freezes at just 32°F (0°C), so wet natural gas must be dehydrated to prevent ice from forming.
  • Cryogenic processing & distillation, to separate natural gas liquids (NGLs).
  • Fractionation applications, which remove carbon atoms and separate heavier hydrocarbons (ethane, propane, and butane) from the gas stream: Once separated, each component is sold as a usable by-product or feedstock.         

The process of removing all additional carbon atoms from the gas stream produces methane, which is pipeline-quality dry natural gas.  Once processed, Methane is distributed to downstream consumers (used as a feedstock for power generation), and it is can also be compressed or liquefied.

AMINE TREATING

Amine gas treating utilizes various alkylamine solutions to remove hydrogen sulfide and carbon dioxide from natural gas.  Midstream plants treat raw gas transported from the wellhead to produce sweet gas for further processing.

 

 

   

Sealless Magnetic Drive API-685 Centrifugal Pumps

Sundyne sealless magnetic drive API-685 Centrifugal pumps are commonly used in the reflux and lean amine processes. These types of applications can pose challenges to pump seals by creating magnetic losses and by heating the process fluid.  But Sealless magnetic drive pumps from Sundyne HMD Kontro overcome these challenges through containment shells which eliminate eddy current losses in the pump and reduce energy consumption.  With no seals to repair, or replace, maintenance is minimized - and worker/environmental safety is also improved through leak-free operation.

   

Sunfo High-Pressure Medium-Duty Centrifugal Pumps

For some midstream applications which do not require API compliance, more cost-effective pumps are available that still offer similar performance.  Sunflo Industrial Grade pumps are the preferred choice for applications with low NPSH requirements.  Their small footprint enables them to be deployed in any plant environment.  316 stainless steel construction (with higher alloys available) enables Sunflo pumps to resist corrosion, and Sunflo’s Thrust Bearing capabilities enable the pumps to withstand upset conditions and operate reliably round the clock.

MOLE SIEVE DEHYDRATION

 

 

 

Because Natural Gas condenses to LNG at a temperature of -260°F (-160°C), and water freezes at just 32°F (0°C), wet natural gas must be dehydrated in mole sieves to prevent ice from forming.

Mole sieve dehydration units remove water vapor from natural gas as it enters the midstream process after amine treating. A mole sieve process utilizes molecular materials to sift or separate the gas from water. Dehydration separates' the water from natural gas for cryogenic processing. Inlet gas must be free of water vapor so that it will not freeze in the process.

 

The basic mole sieve design consists of two or more units. One unit operates in dehydration mode with the other in regeneration mode. As the dehydration unit becomes saturated with water vapor, it is automatically switched to regeneration mode while the regeneration unit becomes active in dehydration mode.

Sundyne integrally geared centrifugal compressors are precision engineered to provide pulsation and vibration free operation. Built to meet API standards, they will run continuously for up to 5 years, delivering oil-free process gas with no emissions. Their compact footprint and high efficiency make them perfect for handling mole sieve regeneration and dehydration (refer to the diagram below).

CRYOGENIC PROCESSING PLANT

 

A cryogenic processing plant, also referred to as a striping plant, is a facility where natural gas flowing from wells is cooled to sub-zero temperatures (-120 degrees Fahrenheit, -84 degrees Celsius) in order to condense liquids that naturally occur within the natural gas. These liquids are referred to as NGL's or Natural Gas Liquids.

 

NGL's generally include butane, ethane and propane. After separation, NGL's are shipped to market and often used in refineries and petrochemical plants for fuel or feedstock. The methane gas that remains after removing the NGL's is transported via pipeline to be sold and distributed to businesses and households.  

 

 

Sundyne integrally geared centrifugal compressors are widely utilized for regeneration of the demethanizer process. They run continuously for 5 years delivering oil free process gas with no emissions. Sundyne compressors are ideal for skid packaging due to their unique modular base plant and are easy to install into your process environment.

HOT OILS

Hot oil systems are designed to store and move heat transfer fluids used for midstream gas process heating. The heat transfer fluid is normally stored in an elevated insulated vessel. Sundyne HMD/Kontro sealless magnetic drive centrifugal pumps are utilized to circulate the heated fluid from the storage tank through an electric process heater, gas fired heater or exhaust heat exchanger. The heat transfer fluid’s elevated temperature is then used to safely heat a process system and is then returned to the storage vessel.
