Case study: The science behind amine process column corrosion and remedial solutions
This case study examines how and why corrosion takes place within amine vessels, the corrosion mitigation strategies available, and a comparison of high-velocity thermal spray (HVTS) with a low-velocity alternative.
A competitive study for the behavior of amines in acid gas
Natural gas is the most common fossil fuel. However, because it exists in deep underground reservoirs, it may contain several non-hydrocarbon components [e.g., hydrogen sulfide (H2S) and carbon dioxide (CO2)].
Simplified simulation model for an LNG terminal
The natural gas liquids/liquefied natural gas (NGL/LNG) value chain encompasses the production, processing and liquefaction of natural gas (NG) to LNG, its long-distance transportation, and its regasification as it travels from the wellhead to end users.
Decarbonize LNG liquefaction with pre-combustion CO2 capture technology
In recent years, lifecycle greenhouse gas (GHG) emissions studies of the natural gas industry have drawn attention to the significant environmental impact of liquefied natural gas (LNG).
Considerations for not providing a dedicated spare pressure-relief device
Pressure-relief devices (PRDs) play a critical role in the hydrocarbon processing industry.
Engineering assessments in support of pipeline safety: Emerging trends and approaches—Part 1
Engineering assessments will increasingly be applied in the pipeline industry to demonstrate related fitness-for-service and appropriate safety margins to stakeholders, including industry, regulatory agencies and the public.
Soft startup of best practices for commissioning of amine plants
The startup and commissioning of hydrocarbon plants can present unique challenges that, if not anticipated and addressed in the pre-commissioning and commissioning periods, will inhibit plant startup and increase the difficulty of achieving product specifications in a timely manner.
The carbon conundrum: Digital technologies drive sustainability in LNG production and transmission
Shell’s Prelude FLNG (floating LNG) vessel is the largest floating production, storage and offtake vessel in the world, weighing as much as six aircraft carriers and stretching 1,601 ft.
Case study: Sour condensate NGL export pumps seal failure
In a facility, a frequent seal failure occurred on two sour condensate natural gas liquids (NGL) export pumps.
Redundancy via KVM technology keeps critical systems accessible
The proliferation of computers and IT-based systems in industrial process automation has created a need for advanced and flexible system access to these computers.
Digital transformation in LNG requires a long-term, data-driven approach
The energy transition has begun, and natural gas, especially in its liquefied form, promises to play a key role in enabling the shift to a greener and cleaner global power picture.
