Alfa Laval - Smøreoljeprosesser

Smøreoljeprosesser

Fjerning av det aromatiske innholdet og voks før basisoljen er klar for blanding omfatter kritiske raffineringsprosesser. Varmevekslere som er installert i disse prosessene, må avgi energi til destilleringstårn, kondensere damp, kjøle produkter og gjenvinne energi. Alfa Lavals kompakte varmevekslere er ypperlige verktøy for å maksimere effektiviteten ved bruk av minst mulig tomteareal.

Optimizing refinery lube oil processes

Making petroleum lubricating oils from crude oil calls for smart processes that save energy, reduce maintenance, increase production and cut investment costs. Alfa Laval has the expertise, technology and services to meet refinery needs.

Increasing energy efficiency in refinery lube oil processes

Whatever solvent is used to remove aromatic compounds and wax, several columns are needed to recover the solvent from extract, raffinate, wax and lube oil. To minimize the energy input to these evaporators and fractionating columns, it is necessary to recover as much energy as possible from the hot fractions and reuse it to heat the column feeds.

High-efficiency Alfa Laval heat exchangers maximize energy recovery using minimal plot space, thereby significantly reducing energy input to the process.

CAPEX savings

Traditional shell-and-tube heat exchangers can be  expensive. This is because energy recovery for lube oil processes usually requires several large, bulky exchangers in series.  Installation costs, including installation on construction, push costs even higher. High-efficiency Alfa Laval heat exchangers, on the other hand, help reduce investment and installation costs while delivering a maximum efficiency on minimal plot space.

Proven technology for refinery lube oil processes

Alfa Laval has more than 100 heat exchangers operating as interchangers, reboilers, condensers, heaters and coolers in lube oil plants around the world. Some lube oil plants have installed an Alfa Laval compact heat exchanger in every position that requires a heat exchanger.
