Efficient protection against biological growth of organisms

Mounted units for offshore installations

Sanilec® systems are skid-mounted units designed to meet demanding area classification requirements in offshore installations.

In situ sodium hypochlorite generation

These systems use a proven electrochemical process to generate sodium hypochlorite from seawater. This technology is ideal for controlling biological growth in spray water systems used in fire situations, as well as in cooling and fire protection systems.

SANILEC

Benefits without undesirable side effects

In situ generation of sodium hypochlorite is an economical and safe method for producing this potent biocide and disinfectant agent in offshore marine applications.

When injected into the cooling water circuits, the sodium hypochlorite solution generated on site provides efficient protection to the equipment against the biological growth of organisms such as algae, snails, etc.

This is achieved without experiencing the undesirable side effects associated with the use of commercial sodium hypochlorite, such as the accumulation of hard deposits due to the reaction of excessive alkalinity with dissolved substances in the water. In addition, the risk associated with the transport, storage and handling of chlorine gas is eliminated.

Versatile capacity for various installations

Sanilec® systems range in capacity from 1.2 to 21,600 kg/day, making them suitable for a wide range of offshore installations requiring biological growth control in cooling or seawater protection systems.

Different uses

Fire Water Systems
In offshore installations using seawater in fire water systems, the biological growth of organisms such as mussels, snails, algae, etc. can restrict the fire water intake and jockey pumps. Therefore, it is necessary to consider the use of Sanilec® equipment to avoid flow restrictions that compromise the performance of vital safety equipment. Keepex offers skid-mounted systems which provide a shock dose of sodium hypochlorite at predefined intervals in the suction of the fire pump, as well as a continuous dose of sodium hypochlorite in the suction of the jockey pump. These shock doses keep the fire water pump suction clean and free of microorganisms that cause biological growth.
Cooling Water
When seawater is used to cool systems, biological growth or accumulation of marine organisms can reduce system efficiency and increase maintenance frequency, thus decreasing the life of the process equipment. Keepex offers a system that receives pressurized seawater and produces sodium hypochlorite at a concentration of 40 to 1660 ppm. This sodium hypochlorite solution is injected at any point within the system to control the growth of marine organisms. The amount of product injected is adjusted as needed to maintain the desired residual level, which can range from 0% to 100%.
Floodwaters, Offshore Oil and Gas Production Platforms
In flood water systems used on used on offshore oil and gas offshore oil and gas production platforms, sodium offshore oil and gas production platforms, sodium hypochlorite is used to control to control the growth of marine marine organisms in the marine marine compartment, the condenser condenser, heat exchanger and well. heat exchanger and the well. By reducing the growth of marine organisms in the condenser the condenser and heat exchanger, the the condenser and heat exchanger, the efficiency of the efficiency of the system and significantly significantly reduce maintenance requirements. maintenance requirements. The injection of sodium sodium hypochlorite with seawater at the bottom of water at the bottom of oil wells prevents prevents the accumulation of silt and the and the growth of marine organisms in the growth of marine organisms in the oilfield substrate. oilfield substrate.
LNG Terminals
During the liquefaction and regasification process of liquefied natural gas (LNG), chlorinated seawater is used for cooling and heating respectively. In situ generated sodium hypochlorite is an excellent substitute for chlorine to control biological growth in these applications.
