Cracking technology

Despite various mechanical attempts to increase throughput, operations were at first conducted in batches, which required the plant to be shut down for the still and ancillaiy cquipineiit to be cleaned out. Until cracking technology entered the picture, refin-eiy operations were inefficient as they captured for use barely 50 percent of the available petroleum. 

After 1942, fluid cracking technology increasingly dominated U.S. petrochemical production. It manufactured high-tonnage fuels for both motor vehicles...

Application Vinnolit s medium-pressure EDC-cracker provides an energy efficient cracking technology operating at moderate cracking pressure, with the benefit of low byproduct formation and long operation cycles between cleaning intervals. 

Score [Selective cracking optimum recovery] A process for making ethylene by cracking ethane or naphtha. It combines Exxon Chemical s low-residence time technology with Brown Root s cracking technology. Developed by Kellogg Brown Root in 1999 and planned to be used at Dow s refinery in Freeport, TX, in 2003. BP planned to use it when it expanded its Chocolate Bayou ethylene plant for completion in 2005.

Kureha crude oil steam cracking technology was devdoped jointly with Union Carbide for the manufacture of ethylene (see Section 2.13.4). By operating at very temperature and with very short xomact dmes (0LOO3 to 0.010 s), approximately equal amounts of acetylene and ethylene can be produced from a number of crude oils. This is illustrated by Table 52 for Indonesian and Arabian crudes, cracked in the presence of steam at 2000 in a steam to feed weight rado of about 5, and with residence time of O.OOS s. In these conditions, the temperature at the reactor exit before quench reaches 1150-C. /...
