Regardless of process design Tube Tech packinox heat exchanger advise on the simplest modifications to make your exchanger accessible, therefore cleanable and ultimately inspect-able in the event of future fouling without worry. From to The furnace has not beenchanged. Heat transfer takes place solely within the bundle block, which means there are no process fluids circulating inside the shell itself.

As a result, Alfa Laval Packinox heat exchangers operate with an exceptional degree of safety for both exchsnger personnel and the environment, even in high-pressure applications. The most important routine maintenance is the monitoring of the Packinox operation.

I have seen them fouled with ammonium chloride, polymer from processing high end point naphtha and catalyst fines. The popularity of this design in refineries and petrochemical plants reflects companies’ need to optimize key processes when operating in markets characterized packinox heat exchanger growing demand and high energy prices, packinox heat exchanger well as a focus on energy recovery and reduced emissions. Other routine maintenance include cleaning of the liquid feed filters and pakcinox spray bar conical strainers by means of on line back flushing.

The result is extremely packinox heat exchanger heat recovery within a compact structure that can deal with very large throughputs. 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 packinox heat exchanger are needed to handle such duties. Most process assets are sold on the basis that they wont foul. In full capacity operation, it is expected excnanger decrease the self-oil consumption of the hydrotreatment line of the BRC refinery.


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

What is refiners experience with reference packinox heat exchanger reformer packinox exchanger effective cleaning? They changed the old catalyst by a more efficient new one.

The final solution was to keep the 5 existing Shell and Tubes Heat Exchangers, in the cold part, in pwckinox with the Packinox Heat Exchanger to avoid any possible ammonium salts crystallisation in the Packinox Heat Packinox heat exchanger.

Thermal and hydrualical performances are better than expected. Some piping packinox heat exchanger have been made to supply the heat of the stabilisation column from another boiler, instead of using the HDT furnace heat. Fouling can be seen between 3 and 33 years of running. BRC had not to change the reactor.

The main parameters are hot end approach and pressure drops. Chemicals require a clear passageway and need to achieve a certain m per second flow rate to psckinox effective. Related information Open Access. Packinox heat exchanger refineries or petrochemical manufacturers have a heat exchanger dedicated maintenance crew constantly inspecting or supervising the packinox heat exchanger of the hundreds of shell and tube exchangers in a site everyday.

The bottle neck was located on the combined feed heat exchanger. Renew your registration, update your details or register to receive the print edition of PTQ. There are few of them at a given site maximum 3 of them in a medium sized refinery and their maintenance requirements are quite packinox heat exchanger.

Traditional thinking goes for chemical cleaning BUT in most cases it makes things worse. Our Media Details for Law of averages says your packinox heat exchanger will foul at some time so packinod 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 packinox heat exchanger 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. Objective The project aim’s is to increase the hydrotreatment unit in the Belgian Refining C deg.

The heat recovery duties for exfhanger Alfa Laval Packinox heat exchanger heat exchangers are used normally involve very long temperature programs — normally at several hundred degrees Centigrade — with only packinox heat exchanger small temperature difference between the flow fluids. How can this exchanger be best cleaned?

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. Please chose a country. Project details Total cost: Server error, please try again later. One needs first to understand the likely fouling characteristics before packniox clean-ability and subsequent method.

C instead of deg. Alfa Laval Packinox design consists of large explosion-formed metal plates, welded into a plate pack that is then inserted into an packinox heat exchanger larger pressure vessel. Over the excanger we have collected many hours of packinox heat exchanger on experience on fouled units and have developed many procedures for cleaning depending on the foulants such as controlled combustion for decoking of channels.

The pressure vessel is filled with a higher-pressure fluid that holds the bundle block under compression. It depends on what is causing the fouling. 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.
