In the past, refiners adjusted cloud point for diesel by adding kerosine. However, with the specifications for ultra-low-sulfur diesel (ULSD) of <15-ppm sulfur, refiners cannot simply add any kerosine. Blends are adjusted with ultra-low-sulfur kerosine (ULSK), which is quickly becoming in short supply. So, what are the possibilities to correct cloud point for diesel? One solution is adding cloud-point depressant additives. Additives can provide options to optimize production of refined products. As with any solution, there are pros and cons. Options for clean fuels. One solution is to add cloud point depressant (CPD) additives to the mix. As a low-cost option, CPD additives can help str
