Is there any information on the experience with fire-flooding an old field with oxygen (not just with air). I've heard there is, but I only get some very limited information on the subject when I Google this topic.
How successful has this been, what is the experience level, etc. etc.
Can anyone point me to some basics for how an ASU plant works? Like pressure, number of stages, outlet pressures of products, purity. Maybe rules of thumb for estimating overall performance
Appreciate.
Can someone provide me with some insight on estimating (very high level) a cost for a radiant-type heat exchanger? The device I'm looking for will operate at 40 bar, 1200 C on the gas phase, and under reducing conditions. I'm looking at 80% efficiency with 1,000,000 lb/hr of gas flow.
Is...
Are there any commercial processes where CO2 and H2 are used directly to produce a useful hydrocarbon product, such as methanol, ethanol, or possibly all the way to paraffins?
I understand in the boiler industry that steam is corrosive, and corrosivity increases with steam temperature. Is there any data showing how steam corrosion increases with temperature (and possibly pressure). Up to 1300 C
I'm modeling a very large project ($billions). What sort of range of discount factor for cash flow in investment does industry typically use for mammoth projects? I assumed a factor of 8%; but I'd like some other advice. This project is akin to something in the oil and gas refining sector...
I realize there are a ton of comments on ethanol. But I ran across a story from a team in Philadelphia that claimed that injecting liquid ethanol into the gasoline engine (probably just before spark ignition occurs), resulted in 20-25% improvement in efficiency (in the engine--not sure if this...
Considering an atmospheric fluidized bed, like one that might be used to burn coal or shredded tires. What would be an reasonable mass throughput per unit area of the bed (assuming the bed is something like limestone/dolomite). I was looking at a process, and trying to figure out how many tons...
I think most nuclear reactors spin their steam turbines at 1800 RPM, or 1/2 the speed of those used on fossil plants. Any idea why the slower rotational speed on the nukes?
Is there any experience (successful or otherwise) on using solvents to extract the oil from shale? I understand thermal heating is one process to drive the oil out, but wonder if solvents (like supercritical CO2 or others) have been explored?
Any experience out there?
At the Shell gasifier in the Netherlands, they use a feed referred to as VFCR. What does that refer to? Is it a liquid? Does anyone know the API gravity or sulfur content?
Years ago, I heard of this novel cycle, supposedly that would improve plant efficiency. In a nutshell, what is the Kalina Cycle, and why (if its an improved design) has it not had much impact on power world (I don't know of anyone who is using it, nor have I seen anyone write a specification to...
Can anybody give me an idea of the largest practical flow achievable through a natural gas pipeline? I'm trying to find out what the experience list is of pipelines moving natural gas. For example, is 42 inch diameter, moving 2 bcf per day at 1,000 psig a good benchmark for a single pipeline...
Does anybody have a link they can send me that would give me some information that 1) summarizes that CO2 is currently extracted from gases (either pipeline or even CO2 produced by combustion) and 2) an inventory of the plants that currently recover CO2 that is produced via combustion? I...
Another H2S question---Has anybody ever tried microwaves to breakdown the H2S? I haven't looked at the thermo, but I figure that the structue might be labile to microwave degradation. Any thoughts?
Does anyone know if there has ever been a commercial process to remove low concentrations of H2S from a gas flow? Since H2S reacts with Ag to make the sulfide, I was curious if silver could be used (under reducing conditions) to act as a final filtration to scrub the gases free of sulfur (or...
I understand that RECTISOL is a possibly a trademarked name for a refrigerated methanol gas scrubbing process (licensed by Linde or Lurgi).
But can a refrigerated methanol process be designed without having to get a license from the original designer? Methanol as a solvent (for CO2, etc) has...
Does anyone know where I can go to get an estimate for processing 100,000 scfm of synthesis gas (containing H2S, CO2, and COS) to reach sub-ppm levels of sulfur in the gas? This gas is 45% CO, 30% H2, 8% CO2, some H2O, and % level of sulfur. Who supplies this type of scrubbing device? (I'm not...
A landfill gas produced at 1,000 cfm is roughly 50% CO2. What technologies would be applicable to extracting the CO2 from the gas? Any idea of how much $ such a system might cost (ignoring the cost of CO2 compression)
