OGF Article Taking on the Technical Challenges of Sour Gas Processing

Developments in the processing of sour gas were the topics of several papers presented at the 2014 Abu Dhabi International Petroleum Exhibition and Conference (ADIPEC) last month. Sour gas reserves, historically left undeveloped because of the technical challenges and cost involved in their extraction and processing, are being revisited as potential sources of supply in areas with high demand for natural gas. Only in recent years has technology advanced to an extent that makes processing of sour gas with high carbon dioxide (CO2) and hydrogen sulfide (H2S) feasible. The Middle East region is particularly interested in tapping its challenging gas reserves, of which 60% are sour. The United Arab Emirates’ annual rate of natural gas consumption is expected to increase from the current 2.8 Tcf to 5.2 Tcf by 2015, and 6.3 Tcf by 2020. The area’s swift demographic and economic growth in the past decades has resulted in a rapidly expanding electricity grid that relies on power generated by natural gas-fired facilities. The demand for electricity is also outpacing the natural gas supplies in Saudi Arabia and Kuwait. The USD 10 billion Shah field gas project in UAE, the largest sour gas ...

Get the Arlo Ultra if you want the best fully wireless security camera. However, you may

Get the Arlo Ultra if you want the best fully wireless security camera. However, you may want to check out the Arlo Pro 2 if you’re looking for something less expensive. In all my previous testing of Arlo security cameras, I have found the units to produce top-notch videos, supported by some of the best software on the market. Its newest model, the Arlo Ultra (starting at $399), is the company’s best design yet. This weatherproof, wireless camera is the first model from the company to record 4K video, have built-in spotlights and feature dual noise-cancelling microphones. While a few of these features don’t add much value, the rest of the package makes it a very worthy successor to our previous favorite outdoor wireless security camera, the Arlo Pro 2. If you can afford it, the Arlo Ultra is one of the best security cameras you can get. Similar physically to previous Arlo cameras, the slightly larger (3.5 x 2 x 3.1-inch) Arlo Ultra has the brand’s signature smooth, ovoid white body with a black faceplate. Even when attached to the 2-inch-round by about 1.5-inch-tall magnetic mount, the camera has a comparatively low profile.  Unlike earlier Arlo models, t...

Tragic death of Laycock boy, 4, electrocuted by a desk lamp

A FOUR-year-old boy died when he was electrocuted by a modified desk lamp in a caravan where he kept his toys, an inquest heard. Oliver Walker was found by his mother grasping the black desk lamp on the floor of a caravan his family were using while their farmhouse home at Laycock was being renovated. The “bright young boy” who loved tractors lived on the farm with his parents Charlotte and Andrew Walker and his younger sister. His mother started CPR on little Oliver on top of a bail of hay while his uncle Ben Walker frantically dialled 999 on March 13 last year. Coroner Martin Fleming said Oliver had been found in the “most distressing circumstances imaginable”. The desk lamp – which had never been seen by his family before – had been modified so it could be used with a 12v supply by-passing a transformer in the base. However, the mains electricity supplied to the caravan was 240v – the usual voltage for household sockets – and the chrome rods connecting the base to the bulb had conducted the electricity once plugged in, Bradford Coroners’ Court heard. The family was carrying out building work on the farm at the time of the accident and had purchased two caravans in December 2...

A tool that enables a hacker or penetration tester to capture RFID card data from up to three feet away will be released next week at Black Hat. Fran Brown, a year ago, was working a penetration test for an electric utility doing an assessment of its SCADA network. His first challenge was to get inside the facility, meaning, in short that he had to break in. To do so, he decided to test the utility’s physical security systems, specifically, the low-frequency RFID proximity cards used for building access. While past research on the problem existed, including Kristin Paget’s groundbreaking 2007 talk at Black Hat DC...

It’s tempting to think of fifth-generation wireless (5G) as just an incremental improvement. 5G is the number that comes after 4G/LTE after all, but the impacts promise to be epic. 5G networks will reach speeds as high 20 Gbits per second, support 1 million devices per square kilometer, and provide 1 msec latency, unleashing the age of IoT. Everything will be impacted by 5G from high-performance cloud data centers to core and access networks to edge services and smart devices. Accenture calculates that 5G will add $500 billion to US GDP annually(1) enabling new industries and revitalizing old ones. New applications will include autonomous vehicles, precision agriculture, and immersive entertainment. Fast, reliable communication with guaranteed quality-of-service (QoS) promise usher in new applications such as connected ambulances, robotic surgery, and widespread use of drones and automated carts for autonomous delivery applications. In addition to new application areas, 5G will also affect existing applications and services. For applications in HPC and analytics, network capacity has historically placed an upper boundary on computing and data handling requirements. For example, ...

Former Workers Say Ky. State Fair’s Ride Provider Lacks Safety Training

The Fireball ride had been running for just over an hour at the 2018 Kentucky State Fair when something went wrong, and ride operator Duanne Haywood and a few other workers went underneath. Haywood was tasked with setting up and running the controversial ride by his employer, North American Midway Entertainment (NAME), last summer at the Kentucky State Fairgrounds. “I was excited because I mean, that’s the ride that I learned on,” Haywood said. “It’s a ride that I enjoy setting up and a ride that I enjoy running.” But soon he would be fighting to catch his breath as several of the Fireball’s other ride operators were scrambling to shut it down again and lift up one of the ride’s heaviest platforms to save Haywood’s life. The NAME subsidiary that runs Kentucky’s fair, All-Star Amusement, was initially fined $7,000 by Kentucky’s Occupational Safety and Health inspectors for three serious violations after Haywood’s injury. Worker safety inspectors found employees were given deficient training and had deficient procedures for its machines, state records show. KY OSH also found that NAME All-Star Amusement had not inspected its Fireball ride since 2015 — not even after a fairgoer die...
