Tankage Dehydration Chemicals

Berryman has state-of-art tankage dehydration chemicals which help the refiner when faced with problems like:

  • Inconsistent raw crude quality has to be processed
  • Unattainable salt out in the desalter
  • Poor water separation and oil in brine

The chemical helps in smooth desalter operations; lesser crude unit system upsets, protects downstream units and reduces cost of pollution.

Desalter Chemicals (Demulsifiers)

Our desalting chemicals work in a wide range of crude APIs and desalter parameters. This helps the refiner to have an enhanced desalter performance with added option of handling wide range of crude varieties.

Overhead Corrosion Inhibitor Chemicals (Neutralizer and Filmer type)

Our specially formulated dew point Neutralizers helps the refiner in protecting the fractionating column’s overhead system from aqueous corrosion. This is done by maintaining a uniform pH profile, from the dew point location to the overhead boot water section.

Antifoulant and Dispersants (For Crude Units and other Downstream Units)

Refiners often face through put limitations, loss of heat transfer and increase in pressure difference across the systems due to the tendency of fouling in the crude oil or the process side of the exchangers and furnaces caused by the different types of impurities present. Our specially formulated Antifoulant Chemicals help the refiners by reducing the fouling tendencies and in some cases even dispersing the fouled substances to increase the unit run length and energy savings cost to the maximum extent.

Antifoam (Both Si based and Organic based Antifoam for all the units)

Foaming can adversely impact the refinery process thereby reducing the throughput. Foaming happens in different locations of a refinery like the crude unit, coker unit, sour gas stripper or propane de-asphalting unit.

Different technologies are used in each application. In coker unit, a higher molecular weight silicon fluid will be more effective, but in propane de-asphalting unit, a much less molecular weight product will function better.

We have Silica based (High molecular weight) as well as Non-Silica (Low molecular weight) based antifoam chemicals  in our product line which can effectively take care of the foaming problem in different units.

Tank Cleaning and Hydrocarbon Recovery Chemicals

Our hydrocarbon recovery and crude tank cleaning chemicals help refiner to:

  • Maximize hydrocarbon recovery from crude sludge
  • Minimize crude sludge disposal environmental and hazardous issues
  • Maximize crude tank storage utilization with much lesser downtime and turnaround time than the conventional methods

Corrosion Inhibitors for all the downstream units like FCCU, Visbreaker, DCU, etc

We have corrosion inhibitor/filmer products which are formulated in such a manner so as to form a stable film at high temperatures in the distillation column overhead and under a wide range of pH fluctuations. It thereby protects the system internals from severe corrosions.

Ni Passivator Chemicals for FCC Units

The nickel containing hydrocarbon deposits on the catalyst of FCC and forms nickel oxide in the regenerator. In the riser section it may be reduced to metallic nickel, which, like metallic iron, catalyzes the dehydrogenation of hydrocarbons to form undesired hydrogen and coke.

High hydrogen yields are undesirable because it can lead to limitations in the FCC downstream operations (the wet gas compressor is volume limited). High amounts of coke can otherwise lead to regenerator air blower constraints, which may result in reduced feed throughput.

Our specially formulated Nickel passivator acts as passivators to immobilize Ni which reduces the poisonous effect of Ni on expensive and valuable catalysts of the FCCU.

H2S Scavenger Chemicals for all the Applications in a Refinery

Hydrogen sulfide (H2S) is a naturally occurring gas contained in many of the world’s crude oils. It is also formed in the refining process by the degradation of sulfur-containing compounds in crude oils at high temperatures. Refiners face significant safety, environmental, operational and compliance issues with respect to H2S contaminations and it’s a very big challenge to tackle these problems.

Berryman Chemicals Inc is one of the largest suppliers of H2S Scavengers in the world. Our specially formulated H2S scavengers are very effective in dealing with the H2S problems in both the Oil Field and Refinery sectors. Our formulations span a broad range and are tested and approved by many third party laboratories and users with respect to their compatibility and harmlessness. Our chemicals are compatible to be used with other additives also.

Flocculation Aid/Deoiler/Coagulants/Filtration Aids used in Refinery Effluent Treatment Plants

Our various specially formulated products for ETP of Refineries are Deoiling Polyelectrolytes (DOPE), Organic Coagulants capable of reducing formation of sludge substantially, Flocculants/settling aids, Filtration Aids for belt press and other filters and Dewatering aids for centrifuge and decanters.

Finished Product Pipeline Corrosion Inhibitors

The internal corrosion of fuel storage and distribution systems can cause a variety of challenging problems. These include

  • Leakages in storage tank and pipelines
  • Fuel oil contaminations
  • Filter blockage from corrosion of products and costly maintenance
  • Replacement of the parts partially or totally

Berryman Chemical Inc‘s specially formulated Corrosion Inhibitor Additives are designed to protect against these problems. The inhibitors are surface-active ‘polar’ molecules, which attach themselves to metal surfaces. Once attached, the molecule’s oil-soluble tail forms a water repellent layer over the metal there by protecting the surface from the corrosion species.
