Defending midstream operations against cyber threats: ransomware
The midstream and LNG sectors already have many strategic and day-to-day operational concerns, but now they must be wary of ransomware, a cybersecurity threat to operational technology (OT).
Fundamentals of turboexpander design and operation
A turboexpander is a rotating machine with an expansion turbine that converts the energy contained in a gas into mechanical work, much like a steam or gas turbine.
Comparative study of DEA and MDEA treatments of acid gas
Egypt’s consumption of natural gas for all end uses (residential, industrial, commercial and power generation) has increased rapidly due to the growth of new markets, the use of natural gas in the production of petrochemicals and fertilizers, and rising demand for LPG.
Upgrade control systems to improve pipeline safety and efficiency
Pipelines remain the safest way to transport hydrocarbons. However, perceptions do not always match reality, as incidents in recent years have stoked public concerns about pipeline safety. To help prevent incidents and maintain and enhance the safety record of pipelines, industry must address one o..
Calculate likelihood of piping failure from high-frequency acoustic vibration
The failure of a piping section at the outlet of pressure safety valves (PSVs) and control valves, where significant differential pressure exists, is a common problem, particularly in gas processing.
Editorial Comment
Global gas is facing a demand hit from the coronavirus pandemic and a structural oversupply in the LNG market following the startups of new LNG export projects in Australia and the U.S.

ControlAir LLC, a manufacturer of precision pneumatic and electro-pneumatic control products, recently announced the expansion of the Type 2000 Electro-Pneumatic Valve Positioner series to include worldwide safety approvals for use with natural gas when paired with the Type 950 Explosion-proof I/P Transducer.
Global Project Data
Hydrocarbon Processing’s Construction Boxscore Database and Gulf Energy Information’s Energy Web Atlas are tracking nearly 400 active gas processing/LNG projects around the world.
U.S. Industry Metrics
On January 24, the near-month natural gas Henry Hub futures price at the New York Mercantile Exchange closed at $1.893/MMBtu, the lowest January closing price for the near-month contract since January 27, 1999.
Gas Processing News
After a record influx of LNG into Europe in 2019, the region is on track to raise imports to nearly 100 metric MMtpy.
Natural gas pipeline systems and operations
In the 4th century BC, Chinese historian Chang Qu described a strange "air of fire" used to light up rooms and to produce salt by boiling brine.
Wearing in PEEK seals
Pressure rise across successive compression stages requires seals at the impeller eye and rotor shaft to prevent gas backflow from the discharge to the inlet end of the compressor.
All-electric LNG maximizes process control in the Arctic
In the high latitudes of Norway, 300 mi above the Arctic Circle on the remote island of Melkøya, is Equinor’s Hammerfest LNG plant.
LNG looks to digitalization to ease the pressure of a tight fiscal market
Natural gas, as the cleanest-burning hydrocarbon and in its abundance, is a significant part of the future energy mix.
Process selection for deep COS removal from feed gas
A plan by Saudi Aramco to increase Saudi Arabia's crude processing capacity includes grassroots facilities for processing approximately 2,500 MMsft3d of feed gas from various offshore fields.
Business Trends: China pushes shale gas drilling amid corporate shakeups
In what appears to be a move to increase domestic energy production and self-reliance, as well as boost competition among foreign companies, China is reorganizing its state-owned energy firms and widening the invitation to shale gas drillers.
Executive Viewpoint: Innovative DCS targets biogas, LNG applications
New technologies, both process and digital, are revitalizing the hydrocarbon processing industry. Gas Processing & LNG talked with Jani Hautaluoma, Director of Process Automation for Valmet Automation, about the application of new production processes and digital advances for biogas and LNG production.
Editorial Comment: A brighter future for methane hydrates?
Methane hydrates are three-dimensional ice-lattice structures in which natural gas is trapped.
Case study: Improve gas processing by controlling condensation
Improved condensation and capture of NGL and water in natural gas cuts costs, maximizes production value, and avoids costly maintenance. .
Gas processing technology for new engineers
Historically, natural gas has been distributed as a priority in the industrial sector, given the greater territorial concentration of consumption and the consequent lower supply cost.
U.S. Industry Metrics
The U.S. has been a net exporter of gas for more than a year, with a sharp rise in exports in 2019 helped by an increase in LNG shipments from eight new trains at three projects: Cameron LNG, Freeport LNG and Elba Island LNG.

Create a data compilation and management program for heat exchangers
Heat is a valuable resource in the gas processing, refining and petrochemicals industries, and the loss of it should be avoided. Process engineers spend much time working to save and use heat in the best way possible, designing and then maintaining plants so that heat can be fully utilized.
Cost-effective, modular technologies for butane, propane and NGL treating
Hydrocarbon processing plants often encounter challenges with feedstocks containing high levels of mercaptans, which concentrate in hydrocarbon condensates and NGL when the mercaptans are not removed upstream by the acid gas removal unit (AGRU) or molecular sieve unit.
Editorial Comment
Australia and Middle Eastern countries, which have been net LNG exporters, are now foraying into LNG imports due to supply issues.
Industry Focus: Mixed performance for Africa’s gas markets in 2019 poses questions for next decade
As 2020 begins, Africa’s gas market is left with a mixed bag of achievements that only partly confirms a prediction by the International Gas Union (IGU) in early 2019 that the continent’s natural gas segment is “facing a potential turning point.”
