Products Description

The Compabloc is a fully welded compact heat exchanger designed for the complete range of process and utility duties. The Compabloc range provides the most efficient, cost-effective, compact and cleanable heat exchanger solution available today.

Design

The Compabloc range of welded heat exchangers with a focus on perfor- mance, compactness, and serviceability.The heart of the Compabloc is a stack of corrugated heat transfer plates in 316L stainless steel, or other material. The plates are laser welded and form a compact core. This core is then enclosed and supported by four corner girders, top and bottom heads and four side panels (see Sectional view of Compabloc). These components are bolted together and can be quickly taken apart for inspection, service and cleaning.The design can be configured in single or multi-pass arrangements in either co-current or counter-current operation, for liquid-to-liquid or two-phase duties.

Operating Principles

The two media in the Compabloc heat exchanger flow in alternately welded channels between the corrugated plates.These corrugated plates promote high turbulence which provides high heat transfer efficiency and help minimize fouling. The media flows in a cross-flow arrangement within each pass (see figure below) while the overall flow arrangement is counter-current for a multi-pass unit (if required the unit can also be designed with overall co-current operation). Each pass is separated from the adjacent passes by a pressed baffle which forces the fluid to turn between the plate pack and the panel.Compabloc's flexible pass arrangements make it suitable for liquid-to-liquid duties with dissimilar flow rates, or two phase condensation or reboiler applications.

Applications

Oil & gas production

• Heat recovery in TEG systems (gas dehydration)
• Heat recovery, cooling, condensation & reboiling in amine systems (gas sweetening, sour service)
• Heat recovery, heating and cooling in crude oil dehydration and desalination systems
• Condensation in vapour recovery units
• Heat recovery, cooling, condensation and reboiling in NGL fractionation systems

Refineries

Various condensing & reboiling duties such as:

• Condensation in atmospheric and vacuum distillation
• Top condensing on fractionators in FCC, hydrocracking, H2S strippers, etc.
• Propane & butane overheads condensing in NGL and alkylation plants
• Reboiling in H2S strippers, sour water strippers and other columns
• Steam generation

Heat recovery, cooling & heating duties such as:

• Cooling of gasoline, kerosene, gas oil, diesel, pump-around etc
• Cooling & heating of bitumen, VGO (vacuum gas oil) and other heavy products
• Fractionator feed/bottom heat recovery
• Pre-heating of crude oil
• Desalted water/feed water heat recovery

Benifits of Compabloc Heat exchanger

• High thermal efficiency saves energy, boosts performance and reduces CO2 emissions
• Improved heat recovery with lower costs means very short payback time
• Compact design reduces installation costs and resolves bottlenecks for increased production
• Compabloc is fully mechanically cleanable, making maintenance simpler, quicker and more cost-effective
• Durable, laser-welded construction minimizes fouling and eliminates corrosion issues
