This report provides an update of the previous basic report listed below
which substantially satisfies the basic reporting requirements for the
installation. Since the previous report there has been some minor
construction, and the dismantling of two processing units at the Lan-chou
refinery. Based on recent large-scale coverage, some units have been newly
identified and the functional identifications of other units have been revised.
The identification of an alkylation unit and a probable catalytic reforming
unit raises the estimated capacity for producing high octane gasoline. The
change in functional identification of two units from crude oil distillation
to solvent extraction reduces the overall estimated capacity of the refinery.

As a result of large-scale photography of July 1971, the functionof
some units in the Lan-chou Petroleum Refinery can now be identified for the
first time and the function of other units can be revised. The location and
current description of all units in the refinery are shown in Figure 1. The
table below shows the units which have a newly identified or revised function..

Since August 1968, the date of the latest photography used in the previous
report, a small unidentified processing unit (Area N2) has been constructed.
Also, a furnace has been added to both the dewaxing units (Area 01) and the
crude oil distillation unit (Area L). The probable hydrotreating unit (Area 02)
and the fluid coking unit (Area V) are being dismantled.
Identification of the alkylation and probable catalytic reforming units in
Area G significantly raises the estimated capacity for producing high octane
gasoline. The change in functional identification of two units in Area M from
crude oil distillation to solvent extraction reduces the overall estimated
capacity of the refinery. Based on the identification of processing units,
the refinery produces straight-run, cracked, blended, and probably reformed
gasolines in a wide range of octane ratings, kerosene, diesel and fuel oils,
lubricating oils, wax, asphalt, and gaseous hydrocarbons.
