Chemical cleaning servicesExperience—the key to the cleaning process

Let our experts put our experience, knowledge and skills to work for you.

Our experienced and highly skilled cleaningspecialists determine the best solutions to meet

your needs and then perform the cleaning in a safe,

cost-effective manner.

Our in-house laboratory can analyze the deposits

in your system and then determine the best method

or removal.

Cleaning with chemicals requires a service provider

who understands the chemistry and critical

stages of the operation. Corrosion rates of metal

alloys differ depending on the metallurgy and type

of cleaning solutions used. Special problems, such

as corrosion caused during acid cleaning, can occur

during chemical cleaning that can seriously affect thesafety of equipment and personnel.

We have the expertise and training that can help

minimize the potential problems associated with

chemical cleaning through the use of specialized

corrosion inhibitors preventing attack on the

parent metal.

Chemical cleaning is a highly specialized service that

requires a thorough knowledge of chemistry, chemicals,

fouling deposits and the effects those deposits have

on your assets. It requires an experienced service

provider who can deliver results.

The cleaning processes use acids, alkalis, oxidizers

and solvents to clean plant equipment or reduce

the cleaning effort. The processes remove scales,

deposits and fouling accumulation from process

equipment during maintenance shutdowns. These

processes are also effective at removing rust, mill

scale and protective coatings from new equipment.

Weatherford’s Pipeline & Specialty Services group has more than 25 years of experience in industrial

chemical cleaning services—using best-in-class technology, people and equipment. We provide a full range

of services for all of your chemical processing needs, from single-ll methodology to a customized approach.




Fouling types vary from plant to plant and can vary over time.

The most common foulants fall into the following general categories:

• Hydrocarbons: oils, grease and bitumen

• Carbons: from soot-like to hard coke

• Polymers: from sticky liquids to dry solids

• Corrosion products: oxides or suldes of iron or copper

• Water scales: hardness and water-treatment products

• Organic matter: weeds, algae and bacterial slimes

• Mud and silt: entrained insolubles

Nearly all equipment has some form of fouling deposits. These accumulationscan cause loss of heat transfer, high-pressure drops and even total blockage.

FoulantsThe many faces of dirt, a multifaceted approach

Often, deposits are a mixture of two or more foulants

and might require a series of different solvents to

facilitate removal. Weatherford personnel determine

the best methods for removing deposits of all types.

With our in-house laboratory, we can determine the

best approach by analyzing the following:

• The chemical composition of the contaminant

• In-house trial removal tests to determine the

best trial solution for a complex contaminant

• Complex mixes of chemicals for best results





Weatherford’s in-house laboratory capabilities are available to

analyze your problems and nd the best solution for you. Our

technical support centers and eld laboratories can analyzedeposits to determine composition and offer the most

cost-effective methods to solve your problems.

Our laboratories conduct studies designed to mimic conditionsin

your plant and apply different chemical formulations to optimize

deposit removal, while minimizing waste generation and

controlling cleaning costs.

Single-ll chemical cleaningEconomical, effective, environmentally responsible

Weatherford’s single-ll chemical cleaning processes

are designed to minimize waste while effectively

removing deposits from your equipment.

Our single-ll methods reduce waste volume

and cleaning time compared to traditional multill

cleaning methods. This advantage minimizes

your downtime while reducing the environmental

impact—and the impact on your bottom line.

Weatherford understands that every process plant

is different, and a ready-made cleaning process

might not t your needs. That reality is why we

offer custom-designed processes for cleaning,

passivation and preservation of your plant.

We offer solutions that t your cleaning needs based

on plant conguration, system metallurgy, chemistryand time constraints. Our experts are here to help

you determine the best solution.
