Refineries / STAR Division
Dewatering Aid
The use of Dorf Ketal's Dewatering Aid for crude oil stored in tanks demonstrates excellent water and salt removal from crude. Tankage dehydration as it is commonly termed enhances desalting efficiency. Increased profitability results from reduced corrosion and fouling of downstream equipments.
Desalting Program
Refineries processing opportunity crude slates containing higher filterable solids and BS&W result in frequent desalter upsets as well as exchanger fouling. Slop oils containing high level of solids also contribute to such upsets. Dorf Ketal's desalting programs offer excellent dehydration; superior salt & solids removal with over 90% efficiencies and reduced oil undercarry. Increased profitability results from reduced fouling and lower cost of oil recovery from brine
Crude Unit Corrosion Control
Condensing corrosive gaseous species like HCl, H2S and H2CO3 create a highly corrosive low pH environment in the crude unit overhead system. Dorf Ketal's dual chemical program consisting of neutralizer and filming corrosion inhibitor, injected into the overhead system and reflux line ensure superior corrosion control and reliability of the equipment.
Crude Unit Preheat Fouling
Crude preheat exchanger train and furnace fouling can significantly reduce unit throughput and increase processing costs. Foulant precursors range from scale solids to asphaltene deposition and oxidative polymerization. Dorf Ketal's effective fouling control programs injected into desalted crude provide longer unit run lengths. Improved levels of heat transfer lead to increased profits through higher feed rates and lower fuel costs.
Vacuum Unit Corrosion Control
Low pH due to acid gas condensation in vacuum overhead system results in severe corrosion. An effective neutralizing amine provides good pH control, thus effectively reducing corrosion rates, resulting in less downtime, maintenance, and operational problems.
FCCU Main Fractionator & Gas Plant Corrosion Control Program
Dorf Ketal's effective corrosion control program in the FCCU main fractionator column & gas plant corrosion prevents hydrogen blistering and sulfidic corrosion attack. Fractionator and stabilizer reboiler fouling is thus significantly reduced resulting in increased efficiency and profitability.
FCC Slurry Exchanger Fouling Control Program
FCC slurry fouling due to catalyst fines and asphaltene deposition result in fouling on steam generation equipment and preheat exchangers. Dorf Ketal's effective fouling control program offers excellent Return on Investment (ROI. Through enhanced levels of heat transfer through exchangers and improved quenching efficiency in the main fractionator.
Delayed Coker Foam Control
A good fouling control program increases the run length of furnaces in these units reducing fuel consumption and decoking frequency. Dorf Ketal’s delayed coker and visbreaker corrosion control programs provide increased tube life and enhanced reliability of the system.
Delayed Coker And Visbreaker Corrosion Control Program
Coke drum foaming due to entrained hydrocarbon causes carry over of coke fines to the main fractionator leading to fouling of transfer lines and the main fractionator. Our antifoam with superior foam killing efficiency helps to increase coker throughput and increase profitability.
Tank Cleaning Chemicals
Heavy crudes stored in tanks commonly have sludge deposition occurring at the base of the tanks. These deposits when left untreated, cause tank hold-up, occupy much of tankage space and also contribute to disturbances in operation due to high BS &W and sludge carryover. Quite some oil is also lost in the process of removal of this sludge through normal cleaning procedures. Our tank cleaning chemicals help the refiner treat sludge deposits thereby freeing up the tankage space and generate significant savings in processing costs through crude oil recovery
