The energy sector, especially the oil and gas industry, transports enormous volumes of materials through pipe systems. It can be quite a challenge to keep the pipes free from unwanted, damaging substances such as rust, calcium scale, hydrocarbons and other organic/inorganic materials. Deposits of such fouling substances negatively affect the performance of the process systems by reducing flow, increasing pressure drop, impairing heat transfer or, in the worst case, causing blockages, corrosion or leaks. Although equipment can be designed to minimize fouling, it can never be entirely eliminated and chemical cleaning is thus necessary.
Through many years of experience LICCO Team has build up an unique knowledge of which chemicals to use in which situations. We are constantly testing new chemicals that are more efficient and environmentally friendly, and we only select the best to be used in our service programs. So when you choose LICCO Team as your chemical cleaning partner, you can be sure to get the best possible solution for you, your system, and the environment. You can learn more about fouling deposits in the following.
often form in heat transfer equipment (usually on the cooling water side), inside boiler tubes and on external surfaces of boiler and furnace tubes. The deposits/scale are formed by the combustion of fuels, by the corrosion of equipment or, in heat transfer systems, by precipitation from the water or process stream at elevated temperatures. They mainly consist of one or more of the following components:
Carbonates, oxides or hydroxides of calcium, magnesium, copper and zinc
Phosphates of calcium, magnesium and iron
Sulphides of iron, copper, zinc and ammonium
Sulphides of calcium
Chlorides of calcium, magnesium, ammonium and sodium
Organic fouling formed by biological growth such as slime, shellfish, jellyfish and barnacles is encountered in cooling water circuits. On the process side of equipment, organic deposits (varying from light hydrocarbons to heavy polymers) and coke may be found, depending on the composition and temperature of the process stream.
Mixed Inorganic/organic deposits
A mixture of inorganic/organic fouling is sometimes encountered in water circuits where hydrocarbons and/or chemical products leak from the process side.
