The property curves are developed from pilot plant runs on a similar feed
stock. These are based on total product % volume. Refer to Tables 20 and 21;
Figs. 9, 10, and 11.
The gas to 380
F stream will be routed as the overhead distillate from the
thermal cracker syncrude fractionator to the naphtha hydrotreater and the saturated
light ends unit.
The gas oil stream will be routed to the straight run diesel hydrotreater.
The cracked residue will be routed directly to the fuel oil pool.
The HyGO hydrotreater on cat cracker (FCCU) feed operation. The feed to the
heavy gas oil hydrotreater will be the HVGO stream from the vacuum distillation unit
(VDU) to meet the feed requirements of a FCCU. This hydrotreater will operate on a
blocked operation with the LVGO. That is, it will operate so many days processing
HVGO and the remainder of the “stream” year processing LVGO.
Details of the HVGO operation are in Figs. 9, 10, and 11, with the following
specifics:
Feed to the hydrotreater = 9,275 BPCD
SG at 60 = 0.9218
Pounds/gal = 7.678
Pounds/CD = 2,990,965
% wt sulfur = 3.10
