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. 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.

The most important routine maintenance is the monitoring of the Packinox operation. Other routine maintenance include cleaning of the liquid feed filters and the spray bar conical strainers by means of on line back flushing. Packinox The Packinox design is the largest type of plate heat exchanger currently available anywhere in the world.

The all-round heat transfer solution.

This heat exchanger is suited to medium operating temperatures and pressures. How to contact Alfa Laval Up-to-date Alfa Laval contact details for all countries are always available on our website at www. The pressure vessel is filled with a higher-pressure fluid that holds the bundle block under compression. Server error, please try again later. hfat

Alfa Laval Packinox design is the largest type of plate heat exchanger currently available anywhere in the world. Fouling can be seen between 3 and 33 years of running.

Packinox heat exchanger

Don’t wait for the mail. The double-containment feature at the core of this design, combined with a very limited number of flanges, means there is only a minimal chance of leaks occuring, and the risk of fire or harmful emissions to the atmosphere is virtually non-existent. 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.

Heat transfer takes place solely within the bundle block, which means there are no process fluids circulating inside the shell itself. What is refiners experience with reference to reformer packinox exchanger effective cleaning? Every engineer needs a copy. The upgrade includes the following: 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.

Regardless of process design Tube Tech can advise on the simplest modifications to make your exchanger accessible, therefore cleanable and ultimately inspect-able in the pavkinox of geat fouling without worry. 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.

Request service or support. Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties. Related industries Related services. Motivated by cheaper, cleaner, safer operation than offered by other designs, refiners now more than ever find Alfa Laval Packinox heat exchangers pckinox efficient way to optimize their hydrotreaters. Our Media Details for Stripper bottoms heat exchangers The Alfa Laval Packinox Stripper Bottoms Heat Exchanger was developed excganger recover stripper bottoms heat into stripper feed or ppackinox feed.

The low number of high-pressure flanges in hot hydrogen service such as gasoil hydrodesulfurization greatly reduces combustible vapor leaks and emissions of toxic hydrocarbons and H2S. 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 result is extremely efficient heat recovery within a compact structure that can deal with very large throughputs.

The Online Industrial Exhibition. Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties.

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.

All heat transfer takes place inside the bundle, which operates in true counter-current flow. Chemicals require a clear passageway and need to achieve a certain m per second flow rate to be effective.

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. Open the catalogue to page 4. 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.

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.

Please chose a country. How can this exchanger be best cleaned? The result is extremely efficient heat recovery within a compact structure that can deal with very large throughputs. Request information for Packinox. Open the catalogue to page 3. Alfa Laval Packinox Services encourages all customers to provide this data routinely in order to predict cleaning requirements. However changing run lengths, down and upstream conditions make carryover and fouling extremely common but unexpected by clients so expect it to foul and plan ahead for it.

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. 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.
