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.
