Brembana&Rolle Group can supply any TEMA type Heat Exchanger for almost all Oil & Gas and Petrochemical applications. These units are manufactured in all workshops with a yearly capacity of approx.
9,000 tons. Typical construction materials which Brembana&Rolle Group deals with are CS, 1 1⁄4, 2 1⁄4, Nickel Alloy cladding, copper alloys, titanium.
These Units are installed in Gas Treatment Plants, Refineries, Power Generation Plants. Brembana&Rolle can manufacture units with design pressures greater than 300 barg and temperatures greater than 500 °C.
Exotic base materials are used to manufacture special Heat Exchangers when Chemical Processes involve special products at high temperatures and pressures.
These units are supplied as vertical Heat Exchangers in Catalytic and Hydro-Treatment processes.
Brembana&Rolle can manufacture vertical towers assembled in shop with lengths up to 30 m and weights up to 300 tons.
Brembana&Rolle Screw Plug Closure Heat Exchanger features a special threaded ring to hold the channel cover and contain channel pressure.
This technology eliminates the large channel cover flange and bolts of the conventional designs. The hydrostatic pressure load is taken by the channel body and not by heavy bolts. The bolts on the channel side are only sized for gasket compression loading allowing for a thinner channel design and reduction in the exchanger’s size and weight.
The special design of this Heat Exchanger offers:
• easy dismantling/reassembly for inspection
• diaphragm gasket not welded
• no bolted tube sheet.
The design uses expanded metal baffles (tube supports) made of plate materials that has been slit and expanded. The open structure results in a low hydraulic resistance and enhanced heat transfer. The EMbaffle® allows a longitudinal flow pattern, so that the tube vibration will not occur. In spite of the longitudinal flow, the grid shape generates a turbulence flow on its back side, determining an increase of the Overall Heat Transfer Coefficient. Playing with number and distance of baffles, our engineers can optimize the ratio between Δp and OHTC.
The EMbaffle® design, patented by B&R, offers strong potential benefits:
A Waste Heat Recovery Unit or WHRU is an energy recovery heat exchanger that recovers heat from hot flows with potential high energy content, such as process hot flue gasses or steam from cooling towers or even waste water from various cooling processes such as in steel cooling. Hot water and/or saturated super-heated steam is produced, which can be used in a process or to drive a steam turbine.
A Waste Heat (gas) Recovery Unit turns an environmental liability into positive cash flow with very attractive ROI rates in many facilities.
• Reduced facility emissions
• Reduced purchased gas
• Zero impact on safety relief system
• Extended flare-tip life
• Reduced steam consumption
Thanks to in house developed softwares and HTRI/VGISim packages, Brembana&Rolle is able to support engineering companies as well as end users in the design and construction of the main WHRU system components, like Superheaters, Steam generators and steam Drums, Reaction chambers and Furnaces.
Brembana&Rolle is able to engineer including instruments/electrical and control HW/SW, and offer the complete supply package, boasting cooperation with primary companies including manufacturers of burners, exhaust gas stacks, refractory materials and local control panels/systems.
Brembana&Rolle can supply heavy wall reactors such as Hydrocrackers, Hydrotreaters, CCR and Tubular for Oil & Gas and Petrochemical applications in all kinds of materials, including advanced low alloy steel 2/4 Cr 1/2 Mo V.
These units are mainly manufactured in the Albignasego (PD) workshop with and finally assembled at Marghera workshop with an annual total capacity of approx. 6,000 tons.
Brembana&Rolle supplies all kind of columns and vessels including separators with process guarantee for FPSO and other off-shore projects.
