Four bellows compensate for differential thermal expansion between the hot stainless steel bundle and the relatively cool low alloy pressure vessel.

Alfa Laval Packinox design is the largest type of plate heat exchanger currently available anywhere in the world. Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties. This unique configuration combines the exceptional thermal and hydraulic efficiency of modern plate heat exchanger technology with the traditional advantages of shell-and-tube units under high temperatures and high pressures.

Top and bottom end manholes facilitate access for maintenance or repairs. Alfa Laval Packinox design consists of large explosion-formed metal plates, welded into a plate pack that is then inserted into an even larger pressure vessel. It depends on what is causing the fouling. Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties.

Law of averages says your asset will foul at some time so whatever you have saved on an inaccessible unit today you will lose in replacement and downtime costs due to the inability to clean or inspect. The heat recovery duties for which Alfa Laval Packinox heat exchangers are used normally involve very long temperature programs — normally at several hundred degrees Centigrade — with only a small temperature difference between the flow fluids.

Fouling can be seen between 3 and 33 years of running. The popularity of this design in refineries and petrochemical plants reflects companies’ need to optimize key processes when operating in exchanter characterized by growing demand and high energy prices, as well as a focus on energy recovery and reduced emissions. The result is extremely efficient heat recovery within a compact structure that can deal with very large throughputs. Please chose a country.

Chemicals require a clear passageway and need to pckinox a certain m per second flow rate to be effective. Your request was successfully sent! This crew might get involved with a Packinox inspection once every 5 years so the skills and knowledge required for its inspection might not be freshly available in their minds therefore, we recommend you always contact Alfa Laval Packinox Services directly for advice on cleaning.

This means the heat exchanger plates are only exposed to a pressure corresponding to the difference between the pressures of the two fluids flowing through the block.

Motivated by cheaper, cleaner, safer operation than offered by other designs, refiners now more than ever find Alfa Excjanger Packinox heat exchangers an efficient way to optimize their hydrotreaters. Our Media Details for Every engineer needs a copy. Such compactness also means major savings in infrastructure and installation costs, while the improved heat recovery efficiency results in greatly reduced energy and emission costs.

ViscoLine Monotube Unit Request information for Packinox. Refiners see this as a major step forward in plant safety and environmental performance for new units and exxhanger alike.

Traditional thinking goes for chemical cleaning BUT in most cases it makes things worse.

Such compactness also means major savings in infrastructure and installation costs, while the improved heat packino efficiency results in greatly reduced energy and emission costs. The result is extremely efficient heat recovery within a compact structure that can deal with very large throughputs.

Most process assets are sold on the basis that they wont foul. Packinox The Packinox design is the largest type of plate heat exchanger currently available anywhere in the world. Contact subject Request a quote. The heat recovery duties for which the Packinox heat exchangers are used normally involve very long temperature programs — normally at several hundred degrees Centigrade — with only a small temperature difference between the flow fluids.

Heat transfer takes place solely within the bundle block, which means there are no process fluids circulating inside the shell itself. Considerable cost is saved by eliminating the pressure vessel in favor of a simple set of bolted tie rods which securely clamp and compress the allwelded plate bundle. The small channels and low DP make it easy for the chemical cleaning fluids to bypass the fouled exxhanger rather than removing the deposits.

The most important routine maintenance is the monitoring of the Packinox operation.

One needs first to understand the likely fouling characteristics before establishing clean-ability and subsequent method. This unique configuration combines the exceptional thermal and hydraulic efficiency of modern plate heat exchanger technology with the traditional advantages of shell-and-tube units under high temperatures and high pressures.

The Compabloc welded heat exchanger is probably the most compact and efficient heavy-duty heat exchanger in the world. The upgrade includes the following: Other routine maintenance include cleaning of the liquid feed filters and the spray bar conical strainers by means of on line back flushing. As a result, Alfa Laval Packinox heat exchangers operate with an exceptional degree of safety for both plant personnel and the environment, even in high-pressure applications.

There are few of them at a given site maximum 3 of them in a medium sized refinery and their maintenance requirements are quite low. Related industries Related services.

This heat exchanger is suited to medium operating temperatures and pressures. The Packinox design consists of large explosion-formed metal plates, welded into a plate pack that is then inserted into an even larger pressure vessel. How to contact Alfa Laval Up-to-date Alfa Laval contact details for all countries are always available on our website at www. Server error, please try again later.

Over the years we have collected many hours of hands on experience on fouled units and have developed many procedures for cleaning depending on the foulants such as controlled combustion for decoking of channels. Most refineries or petrochemical manufacturers have a heat exchanger dedicated maintenance crew constantly inspecting or supervising the cleaning of the hundreds of shell and tube exchangers in a site everyday. Additional savings are achieved on bellows and mid-bundle water injection system, as the Alfa Laval Packinox Stripper Bottoms Heat Exchanger requires neither.

I have seen them fouled with ammonium chloride, polymer from processing high end point naphtha and catalyst fines.
