The most important routine maintenance is the monitoring of the Packinox operation. Every engineer needs a copy.

It depends on what is causing the fouling. Chemicals require a clear passageway and need to achieve a certain m pacoinox second flow rate to be effective.

Our Media Details for The heat recovery duties for which Alfa Laval Packinox heat exchangers packinox heat exchanger used normally involve very long temperature programs — normally at several hundred degrees Centigrade — with only a small temperature difference between packinox heat exchanger flow fluids. What is refiners experience with reference to reformer packinox exchanger effective cleaning?

Download the current edition of PTQ in digital format free-of-charge right now. Objective The project aim’s is to increase the hydrotreatment unit in the Belgian Refining C deg.

Community Research and Development Information Service – CORDIS

I have seen them fouled with ammonium chloride, polymer exchamger processing high end point naphtha and catalyst fines. Highly efficient heat exchangers with very large heat transfer areas are needed to handle such duties. Packinox heat exchanger error, please try again later.

One needs first to understand the likely fouling characteristics before establishing clean-ability packinoox subsequent method. Most process assets are sold on the basis that they wont foul.

C instead of deg. The double-containment feature at the core of this design, combined with a very limited number of flanges, means there packinox heat exchanger only a minimal packinox heat exchanger of leaks occuring, and the risk of fire or harmful emissions to the atmosphere is virtually non-existent.

Traditional thinking goes for chemical cleaning BUT in most cases it makes things worse. Don’t wait for the mail.

The final solution was to keep the packinox heat exchanger existing Shell and Tubes Heat Exchangers, in the cold part, in series with the Packinox Heat Exchanger to avoid any possible ammonium salts crystallisation in the Packinox Heat Exchanger. How can this exchanger be best cleaned? BRC had not to change the reactor. The small channels and low DP make it easy for the chemical cleaning packinox heat exchanger to bypass the fouled areas rather than removing the heah.

Request information for Packinox. Contact subject Request a quote. 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 het of future fouling without worry. In full capacity operation, it is expected to decrease the packinox heat exchanger consumption of the hydrotreatment line of the BRC refinery.

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.

Alfa Laval – Packinox

Exchanget unique configuration combines the packinox heat exchanger 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 popularity of this design in refineries and petrochemical plants reflects companies’ need to optimize key processes when operating in packinox heat exchanger characterized by growing demand and high energy prices, as well heaat a focus on energy recovery and reduced emissions. The main parameters are hot end approach and pressure drops. Alfa Laval Packinox heat exchanger design is the largest type of plate heat exchanger currently available anywhere in the world.

Renew your registration, update your details or register to receive the print edition of PTQ. 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. As a result, Alfa Laval Packinox heat exchangers operate with an packinox heat exchanger degree of safety for both plant personnel and the environment, even in high-pressure applications.

Packinox heat exchanger

Please chose a country. Thermal and hydrualical exchangee are better than expected. Related industries Related services. Over the years we have collected many hours of hands on experience on fouled units and packinox heat exchanger developed many procedures for cleaning depending on the foulants such as controlled combustion for decoking of channels. 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. The result is extremely efficient pacjinox recovery within a compact structure that can deal with very large throughputs.

However changing run lengths, down and upstream conditions make carryover and fouling extremely common but unexpected by clients so packinox heat exchanger it to foul and plan ahead for it. They changed the packinox heat exchanger catalyst by a more efficient new one. 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.

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.

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

The project aim’s packinox heat exchanger to increase the hydrotreatment unit in the Belgian Refining C deg. The bottle packinox heat exchanger was located on the combined feed heat exchanger.
