 Equipment

Dew Point Adsorption Systems/Wet Gas, Field Gas Conditioning System – designed to extract Natural Gas Liquids from the sales gas stream in order to remove some propane, butane, C4+ and water and control the hydrocarbon dew point, as well as the BTU heating value. This allows the gas to meet pipeline quality specifications, and avoid costly further midstream gas processing. Venture has multiple system options for when there is a small lean NGL tail of <3%. We have a variety of adsorption options such as Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA), depending on if there is on-site power, and what the constituents of concern in the gas are.

 These systems are also used in Wet Field Gas applications to power prime movers for fracking and drilling activities. They can remove the NGL tail to incrementally increase the gas methane number (MN) to satisfy IC Engine fuel requirements/specs.  Contact us today to learn more!

Dry Gas, Field Gas Conditioning Systems- Reduces pressure using Joule-Thompson valve (two pressure settings, drilling activities vs fracking activities),(Optional) Addition of methanol to high pressure well head gas (hydrate prevention). Next our system Re-Heats Gas using gas-to-gas exchanger, (Different design for drilling & fracking) then separates water and NGLs from well head gas and delivers low pressure gas to on-site fracking and drilling users.

Natural Gas Dryer- Prior to sending the wet natural gas into the cryogenic plant to separate the NGL (natural gas liquids) from the methane gas stream, water needs to be lowered down below 1ppm. Often glycol dehydration system is utilized for bulk water removal, but this glycol dehydration cannot lower the concentration down to 1 ppm. Venture has a regenerative adsorption system that can dry the natural gas below 1 ppm water content.   This low water content prevent hydrate and ice crystals formation in the cryogenic plant piping and heat transfer surfaces. Venture uses molecular sieve media to adsorb the water.  After a pre-determined runtime, the production adsorption vessel is switched to bring a fresh media bed into gas production to continue water removal.   The spent adsorber (vessel saturated with water) bed undergoes a regeneration cycle to desorb the water off of the molecular sieve media.

The switching of the vessels is controlled automatically using a PLC.

The adsorption media is regenerated by heating the spent bed.   Circulated natural gas is compressed then the compressor discharge flows across a heater and this hot gas continually flows through the fixed media bed forcing desorption of the water.   The natural gas and water exit out of the adsorption vessel and is cooled through a heat exchanger.  By lowering the gas temperature, liquid water droplets are separated from the gas stream using a coalescing filter separator.    The natural gas discharge from the coalescing filter is than recirculated back to the suction of the compressor to repeat the heated regeneration loop.

The hot regeneration cycle continues until the adsorption media exit temperature reaches a predetermined limit sufficient to ensure the all the water has been desorbed off of the molecular sieve media.   Once the hot regeneration cycle is completed, the adsorption vessel must be cooled down.

The cool down cycle is achieved by continually recirculating the natural gas and bypassing the heating element and using the cooler exchanger to dissipate the heat from the adsorption media.   Once the media temperature is cooled back down,  this adsorption vessel is placed in standby mode until such time that this vessel is switched back into production to adsorb water from the natural gas feed stream.

The benefits of using recirculating regenerative dryer are:

 

  • Minimal loss of natural gas since gas is continuously recirculated during the hot and cool regeneration cycles.
  • No need for depressurization and re-pressurization steps since the recirculation gas processed during the regeneration is maintained at or near operational gas pressure.
  • Lowering the water to 1ppm prevents hydrate and ice crystal formation in the cryogenic portions of the midstream treatment plant.

Circulating treated gas keeps consistent gas composition so there is less of a tendency for a propane compositional change when switching adsorption beds back into production.

Gas Compression Systems – Venture designs gas compression systems for a wide variety of applications. Venture’s engineering team will select and size all component parts in order to achieve full package integration. Some parts include:

  • Inlet Separators
  • After coolers
  • Gas/Liquid Separators (downstream)
  • Gas Recycle Control
  • Compressor Control Systems

We are capable of full gas compression system integration, selection, and package design.
Venture utilizes various compressor makes and models as well as process modeling to meet your unique application needs.

Slug Catchers

Slugs, or large unexpected volumes of liquids in the gas stream can be detrimental to process equipment. Venture Engineering’s slug catchers are designed to give you piece of mind, in knowing your equipment is safe. Venture provides slug catchers for a variety of oil and natural gas applications. To learn more, feel free to contact us.

Condensate Stabilizers

Condensate is a mixture of liquid hydrocarbons that are separated from gas, which is formed when temperature and pressure decreases, resulting from drilling a well.
Condensate can be processed in order to extract valuable resources, for uses in other applications. If not processed correctly, condensate will not provide the same value.
Venture Engineering & Construction, Inc.  offers a unique solution to processing condensate in our Modular Condensate Splitter Skid-based system. This system splits condensate into multiple byproducts such as: Diesel, Naphtha, Kerosene, and Gas Oil. The unneeded intermediate products can then be sold or used in other applications such as feedstock for other plants. By separating mixed condensate feeds, Venture’s equipment provides valuable products for its clients.  It is the modular nature of our system that allows for quick delivery, swift startup and easy mobility.

Our systems are designed, and fabricated in Pittsburgh, Pennsylvania, in the heart of the Marcellus & Utica Shale formations. This means a faster delivery time for our local customers; as well as the convenience of having access to our local support team of technicians for service and spare parts.
We offer various support packages to meet each client’s unique and individual needs.

NGL system in field

NGL Skid

Hydrocarbons recovered from natural gas are known as NGL’s or Natural Gas Liquids. When a well produces too many NGL’s it is said to have “wet gas.” This wet gas cannot be put into interstate pipeline, so the gas must be treated and NGL’s removed. Venture Engineering & Construction offers solutions for the Oil & Gas market, most commonly in the Marcellus and Utica shale play.
