22 CEMENT AMERICAS • Spring 2017 • www.cementamericas.com NATURAL GAS Trucks at a customer site. in fact, it is usually the plant asking the virtual pipeline provider to slow down fuel deliveries due to equipment maintenance or malfunction or bad weather." According to Evslin, each truck has a meter on it. It is not like buying a truckload of propane or a truckload of coal. The plant only pays for what it uses and that is measured by the meter. Evslin said they are finding a lot of acceptance for this type of set-up from kiln operators. "The reason is that natural gas burns so much more cleanly than coal or oil that the frequency of shutting down the kiln to clean it goes way down. One customer I know of went from a yearly shutdown to an 18-month shutdown for mainte- nance. They just don't have to do it as often." While the equipment outside the plant is being con- verted, the virtual pipeline company is building a com- pressor station on the closest interstate transmission gas line, building decompression and heating equip- ment outside your powerhouse, ordering new trailers and hiring drivers. Most of the work outside your walls is paid for by the virtual pipeline company. Additional Expenses Besides the conversion, the main costs are opex ex- penses. You can purchase the commodity yourself or the virtual pipeline provider can purchase it for you. You pay them for transportation to your facility as you would pay a pipeline for transport. The price is deter- mined by many factors, but the most important fac- tors are your distance from the proposed compression station, the length of contract with the virtual pipeline service provider and the volume of gas purchased. "It is pretty simple," Evslin said. "Connecting your facil- ity to a natural gas virtual pipeline has many advantag- es. It is cheaper than paying for a pipeline extension, it requires much less maintenance than complex scrub- bing equipment, and now that your facility is dual-fuel, it can act as a temporary solution while you wait for the pipeline, should it ever arrive. Additionally, natural gas is a much safer and environmentally friendly fossil fuel, and it can satisfy ever more stringent clean air regulations." Using a clean fuel produced in North America has the positive effect of reducing dependence on foreign oil, and historically it has shown significant cost savings relative to other fossil fuels. Natural gas can now be the solution to a variety of problems facing plants in the mineral industry that use dirty and expensive fuels.
