Pipeline

The purpose of AETL is to ensure that a project is constructed safely; completed in a timely manner, within budget, meeting the requirements of the project drawings, project specifications, right of way line lists and in compliance with all laws and regulations. The AETL group manages a project during its construction phase and delegates to the HSE, administration and inspection groups the direct responsibility to perform the tasks assigned.  The HSE group can be comprised of two independent departments, health/safety and environmental.  The Administration group will be the collection point for all project reporting, documentation, correspondence and material control. The inspection group will monitor and witness all activities performed by the construction contractor in the execution of a project.

AETL has achieved some well-known EPC power plant projects in home and abroad markets. The models of generator set include gas & steam combine, HFO, hydraulic and diesel generator set. We have organizational capabilities and resources to design, engineer, manufacture, procure, supply, erect and commission on turnkey basis, complete Thermal Power Plants with its accessories. We recognize that requirement of each project is unique, and make out the tailor-made solution for our clients.

 

 

Amine / Gas Sweetening Units

AETL specializes in the design of modular gas treating and gas processing facilities. AETL experience ensures the most cost effective gas pretreatment solutions are available to customers in every market. Gas Treating Services are provided through complete facilities and operations, as required, to meet residue gas specifications. Detailed engineering, superb fabrication, stringent quality procedures and prompt delivery along with our extensive experience in oil and gas equipment manufacturing have allowed us to retain our premier position in the industry.
AETL builds products to meet and exceed the requirements of applicable codes and industry standards.

Gas Treating or sweetening are both terms used to describe the various processes for removal of certain contaminants, primarily hydrogen sulfide (H2S) and carbon dioxide (CO2), from natural gas or hydrocarbon liquids. CO2 and H2S are also termed “acid gases” because when absorbed in water, they form an acidic solution. Other reasons to remove these contaminates include toxicity, corrosiveness, freezing problems and control of the overall heating value of the natural gas.

 

 

 

 

 

 

 

 

 

Benefits of Amine Units

  • Reduces CO2 and H2S levels to the required specifications
  • Modular, skid-mounted systems
  • Reduced manufacturing and commissioning times
  • Standardized and proven designs
  • Guaranteed performance
  • Lower installation and removal costs
  • Built in liquid containment to reduce environmental hazards

 

Amine Gas Sweetening Solutions

Amine gas sweetening is a proven technology that removes H2S and CO2 from natural gas and liquid hydrocarbon streams through absorption and chemical reaction. Each of the amines offers distinct advantages to specific treating problems.

MEA (Monoethanolamine)
Used in low pressure natural gas treatment applications requiring stringent outlet gas specifications

MDEA (Methyldiethanolamine)
Has a higher affinity for H2S than CO2 which allows some CO2 "slip" while retaining H2S removal capabilities.

DEA (Diethanolamine)
Used in medium to high pressure treating does not require reclaiming, as do MEA and DGA systems.

FORMULATED (SPECIALTY) SOLVENTS
A variety of blended or specialty solvents are available on the market.

 


Amine Gas Sweetening Process

  1. Sour gas enters the contactor tower and rises through the descending amine. 
  2. Purified gas flows from the top of the tower. 
  3. The amine solution is now considered Rich and is carrying absorbed acid gases. 
  4. The Lean amine and Rich amine flow through the heat exchanger, heating the Rich amine. 
  5. Rich amine is then further heated in the regeneration still column by heat supplied from the boiler. The steam rising through the still liberates H2S and CO2, regenerating the amine. 
  6. Steam and acid gases separated from the rich amine are condensed and cooled. 
  7. The condensed water is separated in the reflux accumulator and returned to the still. 
  8. Hot, regenerated, lean amine is cooled in a solvent aerial cooler and circulated to the contactor tower, completing the cycle.

 

 

Water Injection Pumps


Water injection refers to the method in oil industry where water is injected back into the reservoir, usually to increase pressure and thereby stimulate production. Water injection wells can be found both on- and offshore, to increase oil recovery from an existing reservoir.

We offer the world’s most complete line of ISO 13709/ API 610 pumps with the widest range of hydraulic coverage, pressure and temperature capabilities. Our engineering expertise, applications know-how and installation experience are peerless.

We have proven to be the world leader in meeting the changing and demanding needs of the oil and gas industry. Our ability to understand the industry's high pressure pumping needs is evidenced by the numerous innovative water injection pump designs.

Multiple bearing designs

The pump is offered with a variety of bearing designs to meet application requirements. The standard radial bearing is a self-aligning, antifriction type. The thrust bearing consists of the two single row, angular contact antifriction bearings. Standard lubrication is via an oil ring system and incorporates a constant level oiler and a sight glass. This system prolongs bearing life by ensuring oil penetrates the bearings without foaming. Other bearing designs include the following:

• Split sleeve radial and ball thrust
• Split sleeve radial and tilting pad thrust
