Title: Cetane improvement via the DIESEL-B process

Conference ·
OSTI ID:5173530

The DIESEL-B Process is a new process offered by Calsyn which is targeted toward significant cost savings - up to half the cost of conventional cetane improvers. Pay out of the low capital investments - perhaps $0.5 million - may be obtained in some cases in less than one year. The process involves on-site treating of a small slip stream - about 3% of the diesel pool. Refiners have developed quality fuels for diesel engines which would be suitable for the many diverse applications of these engines. Over the years a fair consensus of required quality specifications has evolved, most importantly those of the major pipeline operators. Ignition characteristics, as defined by cetane number or cetane index have been the most important, but other controls designed to insure stability, color, carbon content and the like are also essential constraints for the refiner. Refiners have historically been able to meet demand for motor diesel fuels by blending the higher quality virgin and hydrotreated materials with a variety of lesser quality stocks, such as cat cracker light cycle oils, coker cycle oils, thermal cycle oils and the like. But because of the typically poor engine performance properties of these latter materials, refiners have had to employ a variety of additives, most importantly cetane improvement additives, cost for which can be substantial. Calsyn is pleased to announce the development of the DIESEL-B Process for improvement of diesel fuel ignition characteristics in response to the growing need for cost cutting methods for the bread and butter portions of our business.
