ENGINEERS at Coolbrook and ABB have set their sights on replacing steam cracking technology with a novel turbomachine called the Roto Dynamic Reactor (RDR) that they will pilot at a chemicals site in the Netherlands later this year.
That camaro in your header picture is turbocharged and supercharged! Applies perfectly for those using multiple power adders to their savings like 401k and HSA. Great post, this will help me convince friends and family the advantages in a visual format, thanks!
For the first time, the freely available password cracker ocl-Hashcat-plus is able to tackle passcodes with as many as 55 characters. It's an improvement that comes as more and more people are relying on long passcodes and phrases to protect their website accounts and other online assets.
Another enhancement is the support of a new technique that allows crackers to radically reduce the number of password guesses by customizing their attacks to the password policy of company or organization they're targeting. Short for Password Analysis and Cracking Kit, the PACK toolkit was developed by researcher Peter Kacherginsky and can save huge amounts of time, particularly when targeting corporate networks.
A turboexpander, also referred to as a turbo-expander or an expansion turbine, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work that is often used to drive a compressor or generator.[1][2][3]
Although turboexpanders are commonly used in low-temperature processes, they are used in many other applications. This section discusses one of the low-temperature processes, as well as some of the other applications.
The figure depicts an electric power-generation system that uses a heat source, a cooling medium (air, water or other), a circulating working fluid and a turboexpander. The system can accommodate a wide variety of heat sources such as:
The combustion flue gas from the catalyst regenerator of a fluid catalytic cracker is at a temperature of about 715 C and at a pressure of about 2.4 barg (240 kPa gauge). Its gaseous components are mostly carbon monoxide (CO), carbon dioxide (CO2) and nitrogen (N2). Although the flue gas has been through two stages of cyclones (located within the regenerator) to remove entrained catalyst fines, it still contains some residual catalyst fines.
As shown in the figure, expansion of the flue gas through a turboexpander provides sufficient power to drive the regenerator's combustion air compressor. The electrical motor-generator in the power-recovery system can consume or produce electrical power. If the expansion of the flue gas does not provide enough power to drive the air compressor, the electric motor-generator provides the needed additional power. If the flue gas expansion provides more power than needed to drive the air compressor, then the electric motor-generator converts the excess power into electric power and exports it to the refinery's electrical system.[14] The steam turbine is used to drive the regenerator's combustion air compressor during start-ups of the fluid catalytic cracker until there is sufficient combustion flue gas to take over that task.
Three main loading devices used in turboexpanders are centrifugal compressors, electrical generators or hydraulic brakes. With centrifugal compressors and electrical generators the shaft power from the turboexpander is recouped either to recompress the process gas or to generate electrical energy, lowering utility bills.
K04-064 - There's still room for improvement!
The series turbocharger of the EA113 (Golf 6 R, GTI, ...) is known for its sensitive reaction to performance optimization, which in the turbo engine is associated, among other things, with an increase in boost pressure. The result is loud noises or turbo damage. Fortunately, the design of the supercharger offers options to not only make it more durable by replacing the fuselage group and adapting the turbine and compressor wheel, but also to significantly increase the performance - i.e. the boost pressure - without putting the turbo at risk.
Installation & coordination:
As an engine repairer and automotive workshop, we can offer the complete range of services required for converting an upgrade turbocharger. The engine management is then tuned on our in-house performance test bench.
The same thing that's stopping a cracker from attaching a simple debugger to your app and changing a "return X" into "return Y". That is, nothing is stopping a malicious user from cracking your software. No protection is uncrackable whether it's integrated in your app, whether your app is obfuscated or wrapped, or whether it's a separate library. If it exists on a computer it can be cracked.
To prevent the other type of theft (crackers distributing your software on the web), we've developed Pirate Poacher (which is free for users of LimeLM). In a sentence, Pirate Poacher scours the web for pirated versions of your app and removes them so that you're not competing with "free" versions of your own app. Used together, Pirate Poacher and LimeLM will prevent nearly all piracy of your app.
First commercialised in 1990, the use of propane dehydrogenation (PDH) technology has grown exponentially in the last decade to address the global imbalance in the supply and demand of propylene, particularly in China. In purpose-built PDH plants ranging from 250 000 to 750 000 t/y of propylene production, turboexpanders are used in the cryogenic separation and recovery sections to efficiently produce the low temperature required while minimising the need for external refrigeration. These expanders have generally been configured as expander-gearbox-generators (EGIs). As this article shows, however, expander- compressors (ECs) are alternatives that bring with them several notable benefits, ranging from reliability to maintenance costs. In addition, expanders have been used in butane dehydrogenation (BDH) to produce isobutylene. Modern, high efficiency radial inflow expanders are engineered-to-order and can be designed and built by experienced suppliers in accordance with the oil and gas industry turbomachinery standard API 617, as well as other purchaser specifications.
NGLs consist of ethane, propane, butanes, and natural gasolines. Ethane is used exclusively as a petrochemical feedstock in steam crackers for ethylene production, and propane is used as a fuel but also as a feedstock by the petrochemical industry. Some ethylene producing plants can process either ethane or propane, or a combination of both, to ethylene, propylene, and other olefins. But as greater amounts of inexpensive ethane are produced through gas processing, the cracking economics favour the use of ethane feedstock rather than propane. As a result, the overall industry cracker yield of ethylene increases, while the yield of propylene decreases (see Table 1).
To speed up Gromit's chores of sweeping up, Wallace activates the 525 Crackervac, a vacuum cleaner with sharp metal teeth and which sucks up things really fast. However it goes after Wallace's crackers after vacuuming one on the floor, but Wallace pulls the box out of its mouth. Wallace tries to stop the 525 Crackervac from getting another cracker. Then throws the box to Gromit who then has a cowboy like showdown with the vacuum. While getting distracted by a cracker Gromit threw in the air, Gromit lassos the machine, which flings him on it's back while sending it out of control. Gromit ties a knot on its neck and then after a few seconds its bag bursts, causing Wallace (and the area where they are) to be covered in dust, and makes Wallace tell Gromit to get the dust pan and brush he was using in the beginning.
Naturally, this calls for equipment that is highly flexible and neither compromises on quality nor safety. This is the path of an Asian biscuit company chose to walk with a knowledgeable companion. Syntegon Technology, formerly Bosch Packaging Technology, helped the cracker experts to boost production flexibility with the latest generation of its compact two-in-one system solution.
Olefins are traditionally produced by steam cracking ethane or naphtha at extremely high temperatures in massive cracker furnaces. The core reacting mixture is heated in tubular coils from the outside of the reaction zone through tube walls using non-renewable fossil fuels and massive amounts of energy. It is this part of the process that is the main source of CO2 emissions in olefin production.
The GMC Crackerbox might be the biggest nostalgia hit for fans of old-school heavy trucks. Everyone who grew up around big rigs seems to have some memory of their dad, grandpa, or uncle driving one, so it's a callback to America's childhood. In turn, clean examples are sought after in a big way, and they're relatively rare to spot in the wild. That's what makes this 1967 with a custom sleeper and twin-turbo Detroit Diesel 12V92 such a showstopper.
The turbos are located behind the cab, where you'll also find a pair of tall twin stacks. Some of the piping runs into the sleeper, which doesn't have a floor yet. It'll certainly be more comfortable when it's finished than the factory option, which reportedly measured only 24 inches.
