Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

The design and technology of gasification equipment have evolved significantly over the past few decades. Modern gasifiers come in various types, including fixed-bed, fluidized-bed, and entrained-flow gasifiers, each tailored for specific feedstocks and requirements. Fixed-bed gasifiers are often used for converting solid biomass and exhibit simplicity in operation, while fluidized-bed gasifiers provide better heat transfer and are suitable for a variety of feedstocks, including waste oils. Entrained-flow gasifiers, on the other hand, are designed for high-efficiency operation with pulverized feedstock, making them ideal for coal gasification.

One of the most appealing aspects of CNG is its potential to mitigate greenhouse gas emissions. Transportation is one of the largest contributors to global warming, accounting for nearly a quarter of global greenhouse gas emissions. Transitioning fleets from traditional gasoline and diesel to CNG can drastically reduce the carbon footprint of transportation. Many cities and states have already begun implementing CNG as a primary fuel for public transportation, such as buses and sanitation trucks, showing that a shift toward cleaner fuel is not only necessary but also feasible.
