![]() The first is incorporating a “no bottle, no flow” mechanism into your sampling system. Bitumen typically flows between the range of 204☌/400☏ to 260☏/500☏, meaning that contact with the fluid can cause severe burns.Ī few things can be done to mitigate these sorts of safety hazards. The heat required for successful high-viscosity fluid sampling means that special considerations must be taken to maintain operator safety throughout the sampling process. Avoiding clogs by taking the appropriate preventive measures is important. Secondly, asphalt typically flows throughġ-inch tubing lines, and replacement parts are costlier than smaller line sizes. First, there’s the downtime required to perform the work. Oftentimes, a solidified bitumen line will require mechanical intervention-and that can get expensive. All of the system media needs to be remelted, and there will inevitably be cold spots that can be challenging to overcome. Once your system solidifies, it’s very difficult to get it flowing properly again. Notes from the Field “Clogs are one of the biggest problems we see when helping our customers with their bitumen sampling systems. Additionally, you can incorporate what is known as a stinger nozzle, which uses a steam jacket to keep the system media hot through its point of exit. For example, you should minimize the number of tube bends and extraneous components within the system. Simplifying the design of your sampling system can help make it easier for you to maintain the appropriate temperature. Maintaining the proper temperature throughout the entirety of your sampling apparatus is important, from your lines to the point of dispensing into your container. ![]() Clearing a clogged line may require technicians to rod the lines, which can be messy and potentially dangerous, and can cause downtime. That means high-viscosity fluid sampling systems must incorporate the appropriate heating elements into their designs in order to maintain viscous fluid flow and avoid potential solidification and clogs within the system. High-viscosity liquids have the tendency to solidify if they are not kept at the proper temperature, typically at least 20☌/68☏ above their pour temperature. Let’s explore some of the considerations that should be made when sampling bitumen or other high-viscosity fluids and liquids. But bitumen is a high-viscosity fluid, and sampling such a fluid-often performed via grab sampling-presents unique and challenging differences compared to traditional methods. Like any refined oil product, successfully capturing bitumen’s value requires ongoing sampling for quality and consistency. “Only a very limited number of refineries produce any asphalt because of the relatively small end market, so it is generally considered to be one of the specialty products.” “The value to a refinery from making asphalt comes not from the high value of the product, but from the low cost of the feedstock,” according to one McKinsey consultant. According to McKinsey, bitumen or asphalt can be a profitable value-add to a refinery’s main production. For many refineries, there is opportunity to maximize the value of bitumen. ![]() Bitumen-which can be combined with aggregate to be sold as asphalt-is typically used in the construction industry for the making of roads, runways, parking lots, roofing, and other applications. It is a dense, large-molecule liquid that results from the traditional vacuum distillation process of crude oil. Capturing that full value requires optimizing all products and byproducts that result from the refining process.īitumen is one of those byproducts. Modern refineries are tasked with maximizing value from the entirety of their production processes.
