VENTECH's Diesel Production Units (DPU) are complete, modularized units ready for immediate
installation, and are designed to be fully erected and operational within two weeks from arrival at a
prepared project site. All equipment is fully warranted for one full year after commissioning or 18
months after delivery. Ventech can have your DPU designed, manufactured and ready for export
shipment from our Pasadena, Texas fabrication facility in as little as five to six months from the
funding of an executed contract.
PRODUCTION FROM EACH DIESEL PRODUCTION UNIT
• NAPHTHA - Naphtha's boiling end point is typically between 150°C (302°F) to
193°C (380°F). This rough-cut hydrocarbon will generally be blended back with the
residuum and re-injected into the crude pipeline.
• DIESEL (DISTILLATE) - This product's typical boiling range is from about 185°C
(365°F) to about 351°C (665°F), and can be used as a heating oil and fuel. The unit
will produce arctic, winter and summer grades of diesel, depending upon the quality
of the crude.
• RESIDUUM - The remaining crude, which is heavier than diesel, typically begins to
boil at about 287°C (550°F). This product is generally blended back with the
naphtha and re-injected into the crude pipeline.
Based on a typical .865 gravity (32° API) crude oil, the Ventech DPU will process the rated capacity
and produce by volume approximately 25% Naphtha, 30% Distillate, and 45% Residuum. Actual
processing capacities, product percentages and boiling points will vary depending on the special
characteristics of your crude. Upon receipt of your crude composition, Ventech will furnish the
yields that can be produced and, at your request, make modifications to your DPU to meet your
special product and design requirements.
Ventech can also furnish any optional equipment needed for further processing of your product
streams such as Distillate Hydrotreaters, Catalytic Reformers, Vacuum Units and Naphtha
Stabilizers.

SPECIAL DESIGNS
► Steam Design - For applications where the owner prefers to utilize steam for the DPU
operations. An optional design can be utilized to furnish a process system that requires
steam for stripping or heating.
► Winterized Design - For applications in severe winter conditions. A special design is
available for operating in environments colder than -20°F (-29°C). This design utilizes
special metallurgy, arctic grade electrical, recirculating air coolers, electric heat tracing and
flushing systems. The process skid is enclosed, insulated, heated and ventilated. The sides
are removable for summer operation and serve as security packaging during shipment to the
site.
► Product Trim Cooling - Air-cooling is utilized to cool products prior to flowing to storage.
If additional cooling is required during the hottest part of the summer, water-cooled trim heat
exchangers can be added
after the air coolers to
operate during the peak
temperature periods.
► Distillate Firing -
Applicable where fuel gas
is not available. The crude
heater will be modified to
burn distillate from the
DPU.
► High Sulfur Metallurgy -
The typical unit is designed
to process crudes with
sulfur less than 1% by
weight. If higher sulfur
crudes are to be used, a high sulfur design is used to increase the alloy content in the heater,
piping, and some of the equipment.
► High Salt Crude Oils - An electrostatic desalter and special metallurgies can be
incorporated in the process design if the crude oil contains high quantities of salt.
