Oil & gas upstream and downstream processing places special

demands on heat exchangers. Such equipment must not onlywithstand corrosive media, two-phase mixtures, extreme pres-

sures and temperatures, but also be extremely compact.

os PefmeTe ranter group has established itsel as a world leader in the

design, development and manuacturing o heat transer equip-

ment or the oil & gas industry.

ranter oers a wide range o gasketed, all-welded and

spiral heat exchangers, proven to meet the toughest custo-

mer requirements. Our patented plate technology enables us

to tailor thermal and hydraulic design to optimise perormance,

reduce investment costs and minimise ootprint and weight.

ranters goal is to build relationships with value by helping

our customers build their business and giving them ideas they

can use or their prot. We do this by working closely with

EPC contractors worldwide rom FEED stage up to delivery

o equipment.

Te ranter Group has worked with many major EPC contrac-tors on global oil & gas projects. Our reerences cover a wide

variety o applications rom downstream to upstream acilities.

Mf & Severanter is represented all over the world by a network o our

own sales companies, licensees and agents. Our ISO9001

approved actories are located in Sweden, Germany, USA,

India and China.

ranter also has a service network covering Europe, North

America, South America, Middle East, Asia and Australia.

Our representatives and engineers can provide service and

support and also train customer sta in handling day-to-day

maintenance.

in a variety o applications, which is why our customers in-

clude major oil companies and EPC contractors worldwide.

Customers in the oil & gas industry trust us because o our

exibility and high level o expertise in material selection, ther-

mal design and process knowledge.

ranter abricates in accordance with all major design codes, spe-

cically ASME Section VIII Division 1 with U stamp, EN 13445,

ranter has its own R&D acilities and the tests conducted are

designed to simulate real operation as would be experienced

in the eld. Tese include thermal atigue testing o welds and

two-phase heat transer perormance.

exchangers can solve heat transer problems. Te most im-

portant o these applications are described in the next pages.

standard available NDE methods consisting o R, U, MPI,

DPI and PMI. ranter also adopts customer specic engineering

standards o major oil companies worldwide.

Raw crude oil contains many contaminants that have to be

removed beore it can be urther processed, particularly water

and salts. Depending on the process used or dehydration /

desalting, plate heat exchangers can be utilised or many di-erent services, such as:

HE-1 Crude oil interchanger - Desalted / dry crude oil co-

ming rom the desalter is interchanged with untreated crude

oil rom the multiphase separator, thus reducing the heat input

to the crude oil inlet heater.

HE-2 Crude oil heater - Heating of the wet crude oil to the

nal desalting temperature by using hot water or steam. I high

pressure steam is used as heating medium an all-welded shell

& plate heat exchanger can be a complement to conventional

gasketed units.

HE-3 Crude oil cooler - e dry crude oil is further cooled by

seawater or reshwater to obtain a suitable storage vapour pres-

sure. o avoid the risk o waxing problems when the crude oil

is cooled to storage temperature, an easily maintained gasketed

unit is benecial to use.

HE-4 Storage tank heater Before ooading the crude oil,

it needs to be heated to allow pumps to work efciently and

optimise discharge rate. Reducing the crude viscosity prior to

ooading is easily done with a prime surface plate heat exchan-

ger using conventional heating mediums.

HE-5 Produced water cooler - Te eedwater to the desalter is

heated by interchanging it with produced water rom the de-

salter. Te risk o ouling problems on the seawater / produced

water side can be avoided by using a gasketed unit, since it

provides high shear stress.

HE-6 Interstage cooler - e hot hydrocarbon gas leaving

the compressor is cooled in the interstage coolers and condensed

liquids are separated rom the gas stream in the ash drums.

Using a shell & plate unit over a tubular unit, saves space and

minimises the utility ow.

Te gas desulphurisation or sweetening process is the removal o

acidic components rom a gas stream, i.e. CO2, H

2S, CO and CS

2,

and is carried out by absorption in a continuous process with re-

generable solvents.

HE-1 Lean / Rich amine interchanger e rich amine con-

taining acidic components is heated by lean amine coming rom

the absorber. ranters gasketed Ultraex plate provides high

shear stress on each side, thus minimises plate ouling.

HE-2 Lean amine trim cooler Before entering the absorber,

the lean amine needs to be cooled to the appropriate absorption

temperature. A gasketed trim cooler is easily maintained and

provides precise temperature control.

HE-3 Stripper reboiler Acidic components are

evaporated in the reboiler. Te short ow path and

highly efcient plate makes the shell & plate heat

exchanger an excellent choice or reboiler duties.

HE-4 Acid gas condenser - Condensable gases are partially

condesed at the top o the stripper column, using a shell

& plate heat exchanger. Te non condensable acid gases

(i.e. H2S and CO

2) leave at the top and is transported to

urther treating.

Dehydration o wet gas removes water vapour rom

the gas stream, and prevents hydrate ormation and

pipeline corrosion, which enables pipeline requirements to be

met. Dehydration is normally carried out by a EG absorp-

tion process.

HE-1 Lean / Rich TEG interchanger e rich triethylene

glycol (EG) is preheated prior to entering the stripper by using

a shell & plate heat exchanger. Te heat exchanger minimises

the required reboiler duty and also respects the low pressure

drop constraint on the lean side.

HE-2 Lean TEG cooler A semi-welded or gasketed plate

heat exchanger is used to cool the lean EG to an optimum

temperature beore entering the absorber, thus enabling precise

temperature control.

HE-3 Vent condenser A semi-welded heat exchanger

can be used on top o the stripping column to condense the

water / hydrocarbon mixture using seawater / reshwater as

cooling medium.

that thermal and pressure atigue is the single lar-

gest cause o ailure in metals, estimated to com-

prise approximately 90 % o all ailures. Tat is

why ranters shell & plate heat exchanger, with its

excellent resistance to atigue, is the preerred solu-

tion in challanging processes.

Gas is compressed in several stages and cooled in interstage

coolers. Condensed liquids are separated rom the gas stream

in ash drums ater interstage cooling, thus liquid is constant-

ly removed rom the gas prior to each compression stage. De-pending on the dryness requirements o the gas it may have to

be dehydrated prior to the nal discharge compression stage.

HE 1,2,3 Interstage coolers - Shell & plate heat exchan-

gers used as interstage coolers provide excellent reliability

due to the high resistance to pressure / thermal atigue. Te

short ow path and the large cross section also make them

particularly suited for two-phase ows with a high LMTD

between the hot and cold side o the heat exchanger.

FCC is the conversion o a hydrocarbon mixture into high

value products such as light oleins and high octane gaso-

line. FCC overhead vapours low to the ractionator where

they are separated into an overhead stream containing thewet vapours and a heavier stream containing the hydrocar-

bon liquids. he heavy liquids or the bottoms product oten

contains ouling products that makes ouling / clogging pre-

vention an important actor.

HE-1 Overhead condenser Te shell & plate heat

exchanger is well suited or condensation o light hydrocar-

bons leaving the top o the ractionator. Te heat exchanger

enables a close temperature approach and is well suited or

preheating the boiler eedwater, thus, saving energy con-

sumption in the plant. Te small hold up volume also pro-

vides ast responses to capacity changes.

HE-2 Bottoms cooler Te liquid hydrocarbons collected

at the bottom o the ractionator can be either reboiled and

reintroduced into the column or be used or preheating a

eed stock. In some refneries the bottoms product is cooled

by a reshwater loop. In both cases, the spiral heat exchanger

contributes to improved process reliability as clogging on

the product side is prevented by its unique eatures.
