Overview

FreewayHave you ever wondered where the fuels that power our vehicles comes from? Or, have you thought about how they turn syrupy black crude into the clear gasoline and fuels that drive our society? Well, ponder no more. You’re about to get a serious introduction to the science and technology of refining and transporting hydrocarbons.

ito-scores-webThere are two ways to learn here: You can simply watch this “Emmy-winning” video above or read more of the background information below. Doing both can double-up on your smart meter. As a side note, the National Academy of Television Arts & Sciences was so impressed with this production, that they awarded it with the Emmy for the top Youth Educational Program-Series in the Midwest. Woo-who! A big shout-out to our ITO youth scientists shown here with their well-deserved Emmy at the awards ceremony in Chicago. See the video to the right.

Before we get started however, let’s consider your previous knowledge base about the petroleum industry. Chances are you’ve likely “learned” more about the oil industry from the news than from hard science sources. One of the rules of being a scientist is knowing how to evaluate potential bias of your information sources (including us). And news by it’s very nature focuses on negative events cast in extreme situations. So it’s little surprise that the news about the oil industry is sometimes presented in a negative light. Oil spills make for dramatic news stories, yet we seldom if ever hear about how the industry plays a vital role in powering almost every segment of our industrial society. Without it, we’d pretty much grind to a halt. Consider that as you begin “refining” your own critical thinking by exploring the science and technology here that begins to decode refining and transporting the fuels that make our modern lives possible.

Let’s start by digging into the science behind the formation of crude oil. Did you know that crude oil was formed from the decomposed body parts of ancient marine organisms?  We’re talking real tiny stuff here like algae and other microscopic organisms such as zooplankton. Nope, there’s no dinosaur juice or ancient forests in that formed oil.

One of the keys to this ancient marine life eventually becoming oil is being trapped in a sediment layer. This layer also had to be free from oxygen in an “anaerobic” environment to prevent scavengers from eating them. As more accumulating sediment layers buried their body parts deeper, pressure and heat essentially “cooked” their organic matter into hydrocarbons. And that’s how crude oil was formed. Despite the common misconception, an “oil reservoir” in the ground isn’t a giant cave in the earth filled with oil. Instead, the oil in a reservoir rock is located in the tiny interconnected pore spaces in the rock. In fact, some rocks such as sandstone, can have up to 30% porosity, or interconnected pores spaces for oil to occupy and flow through. See for yourself sometime by filling a cup with sand, then slowly pouring about a half cup of water into it before it overflows. The water seeped into the 50% “porosity”.

Once a reservoir is drilled into and the crude produced, it needs to be refined. Crude oil straight from a well by itself isn’t useful for much of anything. Oh sure, it will burn, or mess up your clothes. But it sure won’t fly a jet or run in your vehicle. Rather than try to explain the whole process, you’re better off watching the video above as you join our science team as they explore the entire process at Pine Bend Refinery, one of the most complex refineries in North America. As you’ll see in the video, with the help of Flint Hills Resources engineers, they reveal the chemistry behind crude oil and touch on why it’s vital to so many aspects of our lives.Screen Shot 2016-04-06 at 4.55.23 PM

As you’ll see, one of the early phases of refining is the process of “fractional distillation” where they “cook” off the various hydrocarbon fuel “fractions”. Yeah, it sounds confusing. But watch the video for a refined picture of how it all works. You’ll also get to see how the refinery’s very own version of mission control operates this complex refinery that’s the size of a small city. You’ll also learn how refinery experts use physics and technology in the refining process to remove impurities such as sulfur. They also use combinations of catalysts along with heat and pressure to enhance chemical reactions.

What do LegoScreen Shot 2016-04-06 at 4.57.21 PMs have in common with oil refining? As you’ll see in the video, they help conceptualize the refining process of “cracking” longer, heavier hydrocarbon chains of molecules into shorter chains that make up various fuels such as gasoline and jet fuel.

As you’ll also see, it’s pretty hard not to notice the steam coming out of some of the refinery towers. We know that steam comes from water and that fresh water is a precious resource. So our hosts also live up to their name of Into the Outdoors by getting to the bottom of how Flint Hills Resources manages, recycles and protects the water resources they use.

All these refined fuels eventually need to get from the refinery to the industries and businesses that use them, right? We sure can fill up our cars at the refinery. So pipelines offer the safest and most reliable method of transporting those fuels to all the various distribution points in society. That’s why our team decodes all the pipeline connections, with the help of various engineers while exploring the physics behind transporting fuels via pipelines. Because pipelines span huge distances across all kinds of environments, our video team also digs into the technology engineers use to monitor pipeline integrity to prevent leaks and how they repair pipelines that need attention.

To dive deeper into all this the science and technology, watch the video above as your primer on the topic, then expand your learning by sharing the Discussion Guide (coming soon) with your teacher and classroom for some serious peer-driven learning.
