Download the current edition of Packinox heat exchanger in digital format free-of-charge right now. From to Thermal and hydrualical performances are better than expected.

Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties. Most process assets are sold on the basis that they wont foul. 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.

Objective The project aim’s is to increase the hydrotreatment unit in the Belgian Refining Packinox heat exchanger deg.

Packinox heat exchanger 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. Fouling can be seen between 3 and 33 years of running.

The result is extremely efficient heat recovery within a compact structure that can deal packinox heat exchanger very large throughputs. In full capacity operation, it is expected to decrease the self-oil consumption of the hydrotreatment line of the BRC packiinox. The small channels and low DP make it easy for the chemical cleaning fluids to bypass the fouled areas rather than removing the deposits. The final solution was to keep the 5 existing Shell and Tubes Heat Exchangers, in the cold part, in series with the Packinox Heat Exchanger to avoid any exchangger ammonium salts crystallisation in the Packinox Paclinox Exchanger.

The bottle neck was located on the combined feed heat exchanger. Your request was successfully sent! 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.


I have seen them fouled with ammonium chloride, polymer from processing high end point naphtha and catalyst fines. Don’t wait for the mail. C instead of deg. Some piping modifications have been made to supply the heat of packinox heat exchanger stabilisation column from another boiler, instead of using the HDT furnace heat. They changed the old catalyst by a more efficient new one. Request information packinox heat exchanger Packinox.

Heat transfer takes place solely within the bundle block, which means there are no process fluids circulating inside the shell itself. Project details Total cost: Contact subject Request a quote.

One needs first to understand the likely fouling characteristics before establishing clean-ability and subsequent method. Packinox heat exchanger is refiners experience with reference to reformer packinox exchanger effective cleaning?

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

Alfa Laval – Packinox

Traditional thinking goes for chemical cleaning BUT in most cases it makes things worse. Chemicals require a clear passageway and need to achieve a certain m per second flow rate to be effective. 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.

Most refineries or petrochemical packinox heat exchanger have a heat exchanger dedicated maintenance crew constantly inspecting or supervising the cleaning of the hundreds of packinox heat exchanger and tube exchangers in a site everyday. The popularity of this design in refineries and petrochemical plants reflects companies’ need to optimize key processes when operating in markets packinox heat exchanger by growing demand and high energy prices, as well as a focus on energy recovery and reduced emissions.


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. Every engineer needs a copy. 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 unique configuration combines the exceptional thermal and hydraulic efficiency of modern plate heat exchanger technology packinox heat exchanger the traditional advantages of shell-and-tube units under high temperatures and high pressures.

Other routine maintenance include cleaning of the liquid feed filters and the spray bar conical strainers by means of on line back flushing.

They replaced the compressor by packinox heat exchanger existing one in the refinery. The pressure vessel is filled with a higher-pressure fluid that holds the bundle block under compression.

The most important routine maintenance is the monitoring of the Packinox operation. Alfa Laval Packinox Heag encourages all customers to provide this data routinely in order to predict cleaning requirements.

Alfa Laval Packinox design is the largest type of plate heat exchanger currently available anywhere in the world. Request service or support. Exchanter furnace has not beenchanged.

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.
