Description	In the new millenium, the challenges confronting refiners will become increasingly more complex. Increasing demand of lighters, tight capital restrictions and higher refinery utilization will be further magnified by declining crude quality and decreasing fuel oil demand. Since the refiners are finding difficult to process heavy feed stocks in the catalytic processing units, it was thought that R&D work on heavy feed stock will always be desirable by a refiner by adopting thermal cracking route. In thermal cracking for better understanding of cracking behavior of any feed stock, the knowledge of the effect of process parameters on the process is essential. In visbreaking, which is often regarded as mild thermal cracking, each variable plays a significant role in deciding the quality and quantity of the products produced during the process. In visbreaking, temperature and time are the most important parameters and lot of studies on the effect of these two parameters have been already done and also available in the literature, but the third variable Le. pressure also plays a significant effect on the visbreaking process. In the present paper, an attempt has been made to show the effect of variatidn in pressure on conversion (150°C-) using indigenous (Bombay High) and imported (Arab"mix) feed stocks. These two feed stocks have been processed in coil mode and soaker mode operation respectively. The present paper shows the effect of variation in pressure on conversion (150°C-), viscosity reduction and stability of fuel oil (150°C+) produced during visbreaking operation.
