Petrochemical
Complete precision heat and control solutions for the petrochemical
industry
Today Chromalox is a global leader in designed precision heat
and control systems for petrochemical processing. From polyethylene,
propylene, and ethylene plants, to ammonia/urea production,
to aromatics, butane, pentane, and hexane products, to LNG
and MTBE production, no one knows how to apply heaters and
heater controls to petrochemical processing better than Chromalox.
Chromalox is vertically integrated in manufacturing capabilities
and offers full design and engineering for virtually any electric
process heat and control requirement in your plant. Our objective
is helping you to save time and money by reducing installation
labor, reducing start-up time, and ensuring proper operation
to specification to maximize your efficiency and minimize your
downtime.
Heat Trace and Controls
Heat tracing helps avoid process temperature drops that can
lead to freeze-ups in plant areas like cooling towers, instrumentation
lines, process water, safety showers, fire protection piping,
and condensate piping. Providing temperature stability helps
prevent unacceptable viscosity increases and solidification of
fluids in the lines.
Self-Regulating Heat Trace Cable and Controls
Chromalox self-regulating heat trace and control systems can
save energy, reduce maintenance, and the risk of overtemperature.
The cable can be single-overlapped without burnout, cut to length
in the field, and easily spliced. Outperforms industry competitors
in field life, insulation integrity, and resistance against increasing
temperatures.
Constant Wattage Cable
Provides accurate temperature and reliable heat to 300ºF.
Heating output is uniform through its entire length thanks to
its parallel heating core. Flexible and rugged. Withstands steam
cleaning to 190 psi at 392ºF when de-energized. Can be cut
to length in the field, making installation easier.
Mineral Insulated Cable
Ideal for the most rugged pipe tracing applications, up to 1,200ºF.
Fire-resistant and does not support combustion. Provides reliable
electrical ground for safe operation. Custom configurations available
with single or dual conductor cable.
IntelliTRACETM Controls
A complete control solution for heat trace applications with
a modular design for selection of only the features needed for
specific heat trace installations, minimizing the purchase price
and simplifying system configuration. Single-channel system using
microprocessor-based control. Comes completely pre-wired and
assembled. Easily programmed standard features further simplifies
installation, start-up, and use. All IntelliTRACE systems are
designed for universal inputs. Each unit comes in a NEMA 4X glass
fiber reinforced enclosure that includes a solidstate relay (30A
at 40°C), mounted on a heatsink, and with a current transformer
to measure operating current. Optional GFI modules have a shutdown
contactor and illuminated reset switch. A terminal block is used
for field connections on all units.
Custom Power Control Panels
Panels engineered with solid-state controls built to the most
rigid standards and sized for virtually any application or specification.
Select from many NEMAtype enclosures, single- or three-phase
load requirements, voltages, transformers, fusing, contactors,
firing cards, and more. We can design the power contro panel
best-suited for your specific application.
Auxiliary Electric Steam Boilers
Chromalox auxiliary steam boilers can be placed anywhere steam
is required and electricity is available. They are ideal for
remote locations where plant steam is not economical, providing
hot water or steam on demand for emergency or maintenance downtime
backup. They are simple to use, operate cleanly, and require
minimal maintenance.
Hazardous Duty Convection and Blower-Type Heaters
Chromalox hazardous duty convection and blower-type heaters
provide comfort, freeze protection, and moisture protection in
areas like switchgear, control rooms, outbuildings, and pump
houses—particularly where the possibility of explosion
or fire exists. Ruggedly designed Chromalox convection and blower-type
heaters are UL-listed and CSA- and MSHA-certified. Models are
available for wall or ceiling mounting.
Large Tank Heaters
Chromalox large tank heaters provide cost-efficient heating
of stored viscous materials by precisely sequencing operation
to take advantage of off-peak electricity rates. They require
very little upkeep and maintenance. That helps reduce both labor
cost and the time and material costs of inefficient heating.
Chromalox offers a number of large tank heater solutions to meet
the needs of petrochemical plants.
Flanged Immersion Heaters
Flanged immersion heaters provide virtually 100 percent energy
efficiency for the heating of large oil tanks. Their bayonet
styling provides high watt densities, and available temperature
control options permit extremely tight process temperature tolerances.
A wide range of standard designs is available for immediate delivery,
or Chromalox can design a custom solution for you.
Flexible Tank Heaters
Chromalox flexible tank heaters are ideal for underground tanks
or units without side entry. They spread heat evenly in tanks
made from steel, concrete, or Fiberglas®, preventing hot
spots and carbonization. In addition, they install through normal
manhole openings, so no modification is required. They also allow
for tank system operation with little or no manual attention,
and using them enables maintenance work to be done without draining
the tanks.
Unitary Large Tank Heaters
Chromalox unitary large tank heaters offer low watt density
heating over large heated surfaces with precise temperature control.
They are self-contained, can be maintained with little or no
manual attention, and eliminate the need to drain tanks. Designed
for work under tight space constraints, some models require only
three feet of space for installation or removal. And local control
panels, complete with weatherproof enclosures, help prevent overtemperature
operation and damage from power surges.
Circulation Heaters
Chromalox circulation heaters afford high energy efficiency,
fast heating, and uniform heat distribution for numerous petrochemical
plants heating applications such as H2-rich and Claus gas heating,
desulphurization, and air and flue-gas heating. They also provide
high turndown capability, tight outlet temperature control, and
variable flow rates. And Chromalox offers a variety of electrical
terminal enclosures to meet the unique requirements of petrochemical
facilities.
Steam Superheaters
Chromalox circulation heaters also superheat steam, either for
higher process temperatures or to clean the steam itself. Our
smaller units also help make up line losses during transportation
from central steam generation systems. High watt densities and
operating temperatures are obtainable with Chromalox steam superheaters,
thanks to the high quality of their INCOLOY® flanges and
ASME-certified, carbon steel sheathes.
Catalyst Regeneration
Chromalox prewired, skid-mounted circulation heat systems provide
high performance for the burning, reduction gas, and calcination
gas heaters inside catalyst regeneration units. Flanged immersion
elements provide superior strength and rigidity, and can be easily
removed for cleaning and inspection. Heater vessels come in an
array of sizes and meet virtually any kilowatt or corrsion resistance
requirement. And their metal skid mounts, with vessel and control
panel securely attached to the frame supports, enable easy handling.
