■ Heat Exchanger Cleaning
Operating internationally in the oil, gas, power and water industries,
the Chemical Cleaning Services Division within Cape Environmental
provides leading innovative industrial chemical cleaning and
decontamination services for process pipework, tanks, vessels and other
equipment to some of the world’s largest multi-national companies.
■ Hydro-Lasing
The key to our success lies in having the most advanced technology
and a team of highly qualified and dedicated people with the right
skills, training and a can-do attitude. We work in close partnership with
our clients to achieve the most appropriate solution, giving time and
cost efficiencies, as well reducing downtime and increasing overall
production uptime.

Chemical Cleaning
■ Pre-commission chemical cleaning expertise includes HRSG Boilers,
refinery and gas plant compressor pipework systems. High velocity
water flushing is vital between stages and systems may be blown
empty under nitrogen for surface preservation.
■ In-service cleaning capabilities include degreasing, acid and
passivation stages of power station boilers. The furnace side of
boilers may be cleaned using semi-automated high pressure water
jetting. Soda ash washing before and after cleaning may be
employed to neutralise any acidic deposits on the tube externals.
■ Caustic washing on chemical plant vessels to remove/break down
chemical deposits prior to ‘Hurricane’ vessel cleaning with high
pressure water non man entry tank cleaning heads.
■ Acid cleaning of refinery cooling water pipework and pump cooling
water jackets to remove hard water and iron oxide scale. For refinery
plant where there are high sulphur levels leading to potential
polythionic acid production, low chloride soda ash with corrosion
inhibitor may be circulated or sprayed on for neutralisation.

Vapour Phase Decontamination
Cape Environmental use DT3000 chemistry in combination with steam
to ‘vapour phase’ clean oil refinery towers and vessels to remove
hydrocarbon gases/oil, oxidise any H2S, pyrophorics and mercaptans.
This method of cleaning minimises effluent volumes and equipment
required to facilitate fast entry for clients into equipment.
Liquid Phase Decontamination
Cape Environmental use a variety of chemicals to oil and gas free vessels,
towers, pipework and exchangers prior to being opened for inspection.
Pyrophoric scale, H2S and mercaptans will be removed/oxidised and
vessels can be part filled and ‘steamed’ or circulated via spray heads to
minimise filling of equipment to minimise effluent volumes or where design
limitations prevent filling. Liquid phase decontamination may be desirable
where high flow circulation is required to reduce the level of sludge or
solids. Once proven “gas free” the vessel may be opened up and a tank
cleaning head inserted to complete sludge/solids removal to our
MegaVac Tankers which will handle wet or dry materials.
Fin Fan Cleaning
Cape Environmental clean the tube side of fin fans using the Freelance
semi-automated high pressure water unit. The external (air) side of the
finned tubes may be cleaned by pre-treatment using a foam based
chemical to ensure a degree of contact time to remove grease, dirt
and grime. The chemical is fully biodegradable and compatible with
most refinery waste water treatment plants. The residual chemical and
loosened debris are then removed by low pressure water flushing using
a temporary pump, hose and spray nozzle.
Pipeline Pigging
Cape Environmental have extensive experience in pigging small and large
bore pipework from pipeline drying with soft foam pigs to contamination
removal using wire brush or razor back pigs. Some pigs may be dipped in
chemical for drying or metal treatment and in some scenarios Gel Pigging
may be utilised to clean multiple diameter pipework. Pigs may be
launched in specially designed pig launchers using water, air or nitrogen as
a propellant with catchers to suit collection of effluent/debris into drums,
totes, skips, road tankers or tanks (30, 55, 80 or 120 tonne).
Hydrotesting
Cape Environmental have undertaken hydrotesting of a variety of
HRSG pipework on a number of new power plants in the UK to
internationally recognised standards. We supply water storage tanks,
circulation/ transfer pumps, dosing chemicals where required,
temporary mobile steam boilers, all temporary pipework, valves and
fittings as well as all instrumentation including certified pressure gauges,
pressure relief valves and chart recorders.
Air/Nitrogen Purging/Drying
Cape Environmental utilise oil free compressed air to high velocity air/water
flush pipework to create high disturbance factors for removal of loosely
adhered debris. Dry oil-free air is utilised to dry pipes following hydrotest and
nitrogen purging is undertaken when emptying chemicals from a system
after a chemical clean or for removal of toxic/flammable gases.
Vacuum Drying
Cape Environmental utilise this method for drying pipework, vessels and
other equipment to designated dewpoint values where normal drying
techniques are inappropriate. A vacuum is created with a vacuum
pump and residual water is vaporised and displaced by injection of dry
air or nitrogen.
