At businesses worldwide, natural gas continues to make significant inroads as a highvalue energy resource for manufacturing and operations processes. Numerous factors like its “green” environmental impact advantages, price stability, and the ever-increasing proven reserves that are a consequence of leveraging new technologies like fracking, are driving more and more companies to convert to natural gas (NG) from crude oil No. 6.
A high-viscosity residual oil, crude oil No. 6 is the material remaining after more valuable cuts of crude oil have boiled off.
Since many facilities seeking to make this conversion are situated in rural areas outside established NG pipeline networks, they require that natural gas be transported—in its compressed natural gas (CNG) state—via tube trailers. For years, the recognized standard for CNG tube trailers has been eight 2,900 psi tubes capable of hauling approximately 160,000 scf of CNG. Given this payload capacity, such vehicles were never particularly cost-effective at “extending” the pipeline to remote manufacturing operations needing vast quantities of CNG.
