Economizer Treatment Liquid

Soot Deposits Liquid–Preventer in Exhaust Gas Boilers at Low Temperature

PART # AB02 | 0731851223460

PHYSICAL DATA

• Appearance: Green/blue coloured neutral product containing special metal salts. Fully miscible with water.
• Specific gravity: aprox. 1.19 Kg/l
• Flash point: none
• pH (1% solution): approx. 7
• Contains: Nitrates inorganic NOS

DESCRIPTION

Active blend of mineral based salts, containing slag modifiers and carbon oxidation catalyst. Each stick contains approximately 0,5 Kg of SOOT REMOVER.

ADVANTAGES

• Effective above 200°C
• An easily dosed liquid
• Complete coverage of entire exhaust gas unit
• Greatly improved heat transfer
• Neutralises sulphuric acid
• Reduces corrosion and fire risk

APPLICATIONS

Today’s main propulsion units have low exhaust gas outlet temperatures. This is due to increased engine and turbo blower efficiency. Lower gas temperatures are also the result of running at reduced power. The low temperature and reduced gas volume gives increased soot deposition and subsequent corrosion. The increased deposition greatly reduces the thermal efficiency of the economizer. As “dew point” is often reached in the unit, causing the generation of sulphuric acid, the corrosion process is greatly accelerated. Economizer Treat Liquid is a specially developed liquid which is easily dosed into the system, using a special UNIservice injection unit. The special air assisted nozzles create a fine mist so that the liquid vaporizes on contact with the hot gas. The vapor mixes intimately with the exhaust gases and the active material is dispersed throughout the system in microscopic particles. These tiny particles have an extremely large “active surface area” and being light, remain in the gas fully dispersed. This ensures that all parts of the economizer are covered efficiently. In the past, powder products have been developed for this purpose. However, their large particle size and greater weight makes them difficult to inject efficiently, so they cannot reach all areas requiring treatment. This leads to product wastage and ineffective cleaning of the upper areas, where most of the soot is deposited. Economizer Treat Liquid catalyses the post combustion process, resulting in modified soot particles which are dry and non adherent. The resulting deposit is more friable and can be more easily removed by the action of the soot-blowers.

DIRECTION FOR USE

Economizer Treat Liquid is designed to prevent major build ups of soot in service. If the economizer is badly fouled we strongly recommend a pre-cleaning of the unit using Uniservice Gas Side Cleaner or Alkaclean.

Dosage Instructions 1-2 litres of Economizer Treat Liquid is required for every 1000 m2 of heating surface area. This amount should be increased / decreased dependant on economizer design and fuel consumption.

Dosage Period Economizer Treat Liquid should be injected daily or twice daily after soot-blowing.

Dosing Equipment The product must be dosed via the specially developed Uniservice–Injection unit which is made of materials suitable for prolonged contact with Economizer Treat Liquid.

Injection Points In most cases a single injector can be put into the exhaust system immediately after the turbo charger gas outlet. Uniservice Engineers will inspect and make detailed recommendations for exact positioning.

PRODUCT DOSE

Uniservice Gas Side Cleaner Liquid provides a portable Economiser Washdown Unit for low and high pressure jetting of economisers etc. This is a complete pump, hose and lance system which takes sustion directy from the Gas Side Cleaner Liquid drum. Vessels with permanent semi or fully automatic water washing systems can have a Uniservice Pre-Wash Injection Unit retrofitted. This can be custom built to give total control over the timing of the whole operation. Please contact Uniservice Unisafe Srl for further details.

Asteroids

Dry Cleaning System of Turbochargers

PART # AB03 | 0731851223477

PHYSICAL DATA

• Appearance: Brown color, solid natural granules.
• Size: 1.3 – 1.7 mm (new tolerance)
• Corrosive action: None
• Packaging: Bags of 20 – 25 kg
• Special risks and safety advice: None

DESCRIPTION

ASTEROIDS is blown by compressed air into the exhaust pipes before the turbocharger. This method of cleaning should be employed every 24 -48 hours of full-load operation. The interval between cleaning operations depends on the degree of contamination and on the increase in exhaust gas temperature after the turbine. Cleaning must be repeated if the gas temperature after the turbine on full load rises to 20°C (20 K) above the mean temperature. For a turbocharger with several gas inlets, the inlets should be cleaned one after the other. On engines with several turbochargers, these should be cleaned one after the other. The gas inlet temperature before the turbine must not exceed 580-590°C (853-863 K) in order to prevent severe burning of the ASTEROIDS before the turbine. Since it is not possible to remove thick coatings with relatively small quantities of ASTEROIDS, this method must be used more frequently. Injection of the ASTEROIDS into the turbine is best performed at high turbocharger speed, to ensure efficient mechanical cleaning.

APPLICATIONS

Instead of water, dry solid bodies in the form of granules like ASTEROIDS are used for cleaning. A certain quantity of them, depending on the turbocharger size, is blown by compressed air into the exhaust gas lines before the gas inlet casing On account of their hardness and composition (natural solid granules, size 1.3-1.7 mm.) ASTEROIDS have an excellent mechanical cleaning effect (soft blast). As a rule, a turbine should be cleaned every 24 to 48 hours of operation.

INSTALLATIONS OF ASTEROIDS CLEANING SYSTEM

• Before each gas inlet, an adequately dimensioned pipe flange has to be selected and installed in the exhaust gas line (welded or cast eye).
• Manufacture of containers (same number as gas inlets) as shown in the following drawing (welded assemblies).
• Mount the fittings such as valves and the like.
• The container has to be mounted with the strap provided for this purpose at an easily accessible location, the cock or gate valve being at least 300 mm above the corresponding pipe flange in the exhaust gas line. Maximum distance between cock or gate valve and pipe flange/exhaust gas line: 1 m.
• Arrange the compressed-air pipe to the container.

Bio Control F.O.T.

Microbiological Control Agent for Use in Lube Oil and Fuel Oil Systems

PART # AC01 | 0731851223484

PHYSICAL DATA

• Appearance: Light greenish liquid
• Specific gravity (20° C): 1.01
• Flash point: None
• pH (conc): approx. 3
• Special risks and safety advice: None

DESCRIPTION

• Effective against bacteria and algae in oil and contaminated water;
• Special surface active component ensures complete coverage over large areas;
• Simple control & monitoring program;
• Easy to use liquid.

APPLICATIONS

BIO CONTROL FOT is used in oil storage facilities which have problems due to bacteria colonisation and/or algae in the oil/ water interface.

DIRECTION FOR USE

Sterilisation of Luboil Systems: After severe contamination, all areas should be cleaned manually to remove sludge and silt. On large engines, cleaning with undiluted UNICLEAN GP of the casing frame followed by opening and thoroughly cleaning the sumps is strongly recommended. This should be followed by flushing of the entire lubricating oil system with a flushing oil containing 500 – 700 ml of BIO CONTROL FOT for every cubic meter.

Sterilisation of Fuel Storage Tanks: The action of bacteria in fuel during storage is widely misunderstood and its results often thought to be that of stratification of blended fuels due to incompatibility. If bacteria is suspected, water drawn from the fuel storage tank bottoms should be tested and the bacteria count established. If it is above 105/ml, there is a good chance that colonisation has taken place throughout the fuel. In such case treat at 500 - 700 ml of BIO CONTROL FOT for each cubic meter of fuel.
