On 2005-10-12, Matt Barrow wrote: refineries have been expanded (hence the 40% increase in production), but how much is it feasible to keep running old technology? Old technology is much less environmentally friendly? Remember, too, that these were built using 1970s technology. How old is your computer? Are the refineries really using old technology? New ones might not have been built but old ones may have been upgraded with newer technology (possibly how they have output increased per refinery). They were originally built with old technology in place, but I can't imagine they been completely retooled. The guts of my computer are just under 3 years old. However, trivial parts (case, CD-ROM drive, monitor, keyboard) are over twice this age. How much could you upgrade a 16bit processor with a 64bit one given the different data bus? Is it not possible that refineries haven't undergone refits like my computer has - so the ironwork might be from the 1970s, but the guts are much newer? Some machinery in any case is built to last. Railway locomotives, ships, airliners, Here's an example: the Boeing 737-100 engines compared to the powerplants on the -300 and later series. I figure that would be the appropriae analogy. Also, the comparison I used with a 1970's automobile engine with current technology. You could completely replace the engine, but the drivetrain would not be really compatible. power stations, telephone exchanges etc. are often built to have a nominal life span of over 30 years. I would expect the same to be true of a refinery. Their servicability might be 30 years, but imagine a telephone exchange with the old switching technology (mechanical). Or another analogy would be the old copper wire being replaced with fibre optic. There's a point when you just have to chuck the old stuff an build anew. That's probably why the numbers have gone from 362 to 149. Remember, too, that many of these were built using 1970s technology. How old is your computer? You make that comparison again, but I don't think it's valid - Moore's Law (really observation) which drives the computer market is really an exception rather than the norm. It's an analogy, not an example. Use my analogy of automobile engines as another. In any case as we're starting to run into physical limits right now (and generally, desktop computers remain useful for longer - for the typical office job - an 833MHz Pentium 3 computer made 6 years ago is still more than adequate, but using a 6 year old computer 6 years ago was often very painful). For a desktop computer, sure. Now imagine running your servers with old technology, especially with an increased load. The company I worked for coming out of college in 1982 (MS program) was running IBM 370's, then 3083's. The computer room was about 30'x24' . When I left in 1998, they were running HP servers in one small corner of that room. They replaced the old coax cables with FO cables. In sum, there's probably much that can be upgraded in existing refineries, but there are limits.At a certain point you meet the point of diminishing returns. A further question is: how much regulation comes into play when re-tooling or expanding a refinery? |

We are running out of energy generating capacity, actually we weren't running out of energy generating capacity, but the analogy is good since this is another example of price gouging... Sorry, but we are running out of electrical generating capacity and gasoline refining capacity. You don't have to believe it now, but you will in the not too distant future. We won't run out and are not RUNNING out; the capacity can't keep up with demand, and expansion is just about as heavily regulated as the initial construction. Matt The other Matt |

I tend to lose it when people make foolish caveats especially ones that are logical fallacies such as "without all this regulation we'd be in (insert Armageddon class crisis)". ...or "without all this regulation we'd be in (insert free market Utopia)." Gee!! I've been a student of free markets (Chicago, Austrian, Hoover under Sowell, Georgetown under Williams) for 25 years and I don't recall any of them making anything even remotely similar to that claim. If anything, it claims the opposite and refers to it as "chaotic" and a great struggle to stay competitive. As I'm sure you know, I'm not speaking of serious free market thinkers, but rather the simplistic knee jerks who imagine that we'd have plenty of cheap gasoline with no downside consequences if we simply eliminated environmental protection regulations. My point was that such black/white thinking is common on both sides of the environmental protection issue. Well, it certainly is on the environmental side. Which "serious environmental thinkers" have posited that many regulations are overdone? The Free Market is NOT anarchy. Their position is market dictates and is supported by tort law if necessary. I guesstimate you're old enough to remember the old "phosphates" issue from the early 60's. Well, long before regulations on phosphates were in place, Proctor & Gamble and others came up with alternatives. It took only publicity to get most in gear and P&G did well by announcing they were changing their formulations. Their competitors had to keep up. You are aware, I would guess, that much environmental regulation is supported by business, not for the general benefit, but to quash competitors, or for other self-directed benefits. The example I used of coal fired power plants is one; the manufacturer of scrubbing equipment was a BIG supporter. Theirs was not the best solution, but it was the political cronyism solution. |

That has absolutely nothing to do with running a business or a plant. The Japanese taught us well -- the idea is called "just in time." The general idea is that you minimize inventory and don't keep idle machinery. You *do* keep a margin which is called "percent fill at relief" in the telecom world, but no sane person keeps nearly 20% of their plant idle (as was the case in the early 80s). Complete non-sequitur. And, yes, if I owned a manufacturing plant, I would run it as close to 100% capacity as I could. That would make me the most money. In the short run. |

Maybe because the US imports refined FINISHED products (much more costly to buy as well as transport). Not really true. The US only imports about 14% of its gasoline and US gasoline production is up *not* down as your article implies. The article doesn't make a distinction about type of fuel, only refinery capacity. Also, the gasoline to other fuels mix has increased, correct? I suspect the US produces much less heating oil than in the past, most heating being done with natural gas or electric. Total distillates (diesel, heating oil, kerosene) refined in the US have increased 80% over the past 23yrs. As well, what amount of finished product did we import in the past? AIUI, it was zero until the past few years. -- Gasoline imports have increased over time, but still remain at low levels. When you take all the facts together, it seems that refining capacity over the past 25yrs has been driven by economics not regulation. The "lack of refining capacity" hysteria is simply the latest thing for pundits to talk about. The conservatives want to blame the enviornmentalists and the liberals want to blame the greedy oil companies. Hopefully the rules will remain unchanged and economics will continue to drive decision making. Refiners are flush with cash and don't need taxpayer handouts either directly or indirectly through relaxed regulation. Putting things in perspective: we had two "fifty year" storms in two weeks than directly hit major refining areas, having a huge reaction seems unwarranted. One factor that gets ignored is that, if you build new refineries, each one adds huge amounts of capacity. It would only take a few new refineries to create a refining glut.

Probably not that much difference when you are talking about tanker sized
quantities. Just fill it up and pump in CO2 above the gasoline. The CO2 is heavy and doesn't require containment. I don't actually know whether they do this or not but it seems fairly simple. It may be imported by pipeline also. Mike MU-2 "Matt Barrow" wrote in message ... "George Patterson" wrote in message news:vN_2f.4165$vi2.342@trndny04...

Hess (for one) has been importing gasoline since the mid 70s. Not sure when BP got their shoe in the door. During the 1970's crunch? With the costs of transporting gasoline vs. raw petroleum, that would not have made economic sense once the oil bust hit in the 80's. How much more does it cost to transport gasoline (explosive) as opposed to raw crude (merely flammable)? What would the economies be in importing prior to the past few years? -- Matt --------------------- Matthew W. Barrow Site-Fill Homes, LLC. Montrose, CO |

That total capacity figure might just be wrong. The DOE has every major
product up over the period. Mike MU-2 "Matt Barrow" wrote in message ... "George Patterson" wrote in message news:fK_2f.5263$Iq3.2156@trndny01... Matt Barrow wrote: "In 1981, the U.S. had 324 refineries with a total capacity of processing 18.6 million barrels of crude per day. Today just 149 refineries have a daily capacity of 16.8 million barrels." Well, they said *output* is the important thing. Another post said that in 1981 the refineries were producing at 81% of capacity and they are now producing at 96% of capacity. That means that production has increased by 1.055 million barrels of crude per day. The statement is "a total capacity". Capacity, the 18.6Mbbl and 16.8Mbbl, is measured at 100%. Overall capacity has dropped around 10% and the # of refineries has dropped about 55%. Thus, the refineries are running about 40% more product, but with little allowance for downtime or maintenance. As the article states, the existing refineries have been expanded (hence the 40% increase in production), but how much is it feasible to keep running old technology? Old technology is much less environmentally friendly? Remember, too, that these were built using 1970s technology. How old is your computer? In the 1970's, a powerful automobile engine was 350-450 cubic inches and 250-300HP (using today's calculations); today, a 3.5L (217 c.i.) generates the same HP, gets about double the MPG and has a fraction of he emissions, The refining technology is likely on parallel. Would you run your engine just below redline for 30 years? For 30 years without oil changes (no pun intended) or overhauls? Remember, too, that many of these were built using 1970s technology. How old is your computer? Also, the trend is downward regarding number of refineries. More will close in the coming years. Remember , too, what happened when Katrina hit a localized area and took out 20% or so of the overall capacity. -- Matt --------------------- Matthew W. Barrow Site-Fill Homes, LLC. Montrose, CO |

When you take all the facts together, it seems that refining capacity over the past 25yrs has been driven by economics not regulation. I never said otherwise. I also never said our capacity was down. What I'd said was that capacity growth was consrained, that we were becoming too centralized in our geographic dispersment (see the results of Hurricane Katrina). The "lack of refining capacity" That's your point, not mine nor the point of the IBD article. The point is that our capacity is constrained and cannot grow enough to meet growing demand. hysteria is simply the latest thing for pundits to talk about. The article I linked to was hardly hysterical. The hysteric were from Reid and Waxman coming from the other direction. As much, I would hardly say those two bozos had any grasp of the situation.

Well, let's let the market decide how much is enough, okay? |

Believe me, transporting hazard material is never "simple", especially when it jumps from "Flamable" to "Explosive". Check what tanker trucks go through in the final miles from pipeline head or refinery to the gas stations. But, yes, our biggest source of refined gasoline is from Canada which is likely pipelined rather than shipped over water routes. Of course, think how much EPA regulations cover gasoline pipelines.

Capacity is measured at the 100% level, but only a fool runs long-term at or near 100%. Historically, heavy equipment runs at 65-80% of capacity, so as to allow maintenance and fallbacks in the event of a partial system failure. There are strategic issues as well. |
