Slovakian Oil Refinery Calls Foul Play on Membrane Fouling

Slovakian Oil Refinery Calls Foul Play on Membrane Fouling. Filtering water from the Danube river to supply boiler feed water, petrochemical company Slovnaft cleaned its reverse osmosis (RO) membranes every four-six weeks. After investigation, the economics and operation of the RO modules was improved at the refinery, reducing chemical frequency. Nov 1st, 2015. Filtering water from the Danube

Managing fouling in refinery networks DigitalRefining

Crude oil is a complex mixture of petrochemicals and impurities and is prone to fouling. 1,2,3 US refineries are reporting new fouling problems that are a direct consequence of the increasing amounts of domestic tight oils in the crude slate. These problems arise from the changing nature of the slate (one refinery for example is seeing swings upwards of 5-10 API points on a day-to-day or week

ITP Petroleum Refining: Fouling Minimization Project Fact

Conducted a workshop in April 1998 on refinery fouling minimization; representatives from major petroleum companies and service providers reviewed the fouling project, and recommended further work focusing on minimization of crude oil fouling. The interim milestone is to develop best practice design and operation guidelines for mitigating crude oil fouling. The long-term milestone is to

Fouling in Refineries ScienceDirect

In addition, to fouling that occurs in refinery units, the wax constituents of crude oil (and crude oil products) are also capable of contributing the fouling prior to the crude oil entering the refinery. The presence of constituents of wax increases fluid viscosity and its accumulation on the walls reduces the flow line section, causing the blockage of filters, valves and even pipelines

Design Guidelines for Fouling Service rev 15

fouling is found in refinery vacuum and de-asphaltene oil towers and ethylene quench oil towers. If the process is placed on recirculation without the addition of fresh feed with volatile material, the column can foul as the volatile components are removed. In one example an

Alfa Laval Hydrocracking

Normally, the residue from the residue hydrocracker vacuum columns is used to generate high-pressure steam. However, with a low-fouling Alfa Laval spiral heat exchanger, energy can be recovered more efficiently to preheat the feed, which generates greater value to the refinery. Proven technology for refinery hydrocracking processes

Alfa Laval Catalytic cracking

The main fractionator bottoms slurry (decant oil) often has high-fouling tendencies because it contains a high load of catalyst particles as well as coke particles and ash from the fractionator column. Shell-and-tube heat exchangers experience high fouling tendencies due to their inherent design with dead zones in the turning chambers and the risk of maldistribution at the tube sheets. This

The natural oils exhibit low flux and foul the membrane more. Feldman et al.,1998 found that increased oil concentration in the feed decreased the final flux, whereas the crossflow rate, transmembrane pressure, and temperature appeared to have relatively little effect on the final flux. The removal efficiency of the oil was found to be 80-82%. Viero et al., 2007 was claimed that membrane
