The race is on to desulfurize automotive fuels improved hydrotreating processes and a bevy of new catalysts are helping petroleum refiners to meet regulatory thresholds of <10 ppm sulfur without compromising the octane levels of gasoline and diesel fuel.

Getting the most from wet-grinding equipment The degree of particle size reduction required directly impacts media mill design and energy consumption Selecting the right system and grinding media (in terms of material attributes bead size and size distribution) can enhance performance, save energy and trim costs.

For water treatment, consider high-pH reverse osmosis To capitalize on the attractions of high-pH RO, the trick is to minimize potential damage to the membrane by selecting the right pretreatment process.
