As a mechanical engineer and technology professional, who was also one of the original designers of SANILEC equipment in the early 2000s, Jose Lopez understands the piping and structural layouts of seawater electro-chlorination systems inside and out. Today, as the technology manager for both SANILEC and SEACLOR product lines, he is on a mission to make the maintenance and care of these critical systems readily accessible to offshore equipment owners everywhere.

For any near shore or offshore application—from power plant cooling to firewater circuits or any underwater equipment that has access to saltwater, De Nora is the electro-chlorination market leader. De Nora has been instrumental in making sure that essential Oil & Gas equipment stays clean and in optimum condition for almost 100 years—with performance, safety, and environmental concerns as top priorities.

De Nora Retrofit Programs
Extending the life of older equipment can help lower costs, and in many instances, keep your electro-chlorination system working as good as new. Many systems in the field, even those 20-25 years or older, have an excellent maintenance record. Form the retrofit perspective, for them maintenance is more about cell replacement every five to seven years. Other customers may be experiencing downsizing of their staff and need a remote monitoring capability—with the addition of automation, transmitters, and controls so the operator can monitor the health of a system from a single master control center. While remote monitoring has been in practice a very long time—primarily for status and alarms —De Nora can improve that automation by designing a box (seawater in/hypochlorite out), then sending the hypochlorite to ten or more different locations. Automating the process allows the operators to avoid isolating those valves—saving time, money, and unplanned outages.

Other older systems may be ready to change out their technology—either because they have outgrown their capacity and need more chlorination. These SANILEC customers may want to add an additional electrolyzer, or alternatively upgrade to the SEACLOR product line, which features a more compact design and the ability to produce higher capacities. Regardless, these are major decisions that take advanced planning and our field technicians are at the ready to review your specific requirements and make a recommendation.

Mobile Treatment Units for disinfection of produced water in the Oil & Gas industry

Mobile Treatment Units (MTU's) are the safest and most effective oil field water treatment solution on the market today. A MTU is a self-contained system for the on-site generation of sodiium hypochlorite, an effective oxidizer that can be used to disinfect water used in hydraulic fracturing operations and do the heavy lifting in recycling produced water. MTU's are build in  standard C-containers, which are air-conditioned for a safer and more comfortable working environment, and the system comes with all of the equipment needed to generate and inject sodium hypochlorite as well as the testing equipment needed to monitor water treatment operations.

On offshore Oil & Gas production and extraction facilities, the sewage treatment system often manages an enormous amount of raw wastewater, i.e., …human sewage. The untreatable or separated wastes from these systems are commonly referred to as “screened or filtered raw biomass”, or, “wet waste sludge.”

Bacteria in Oilfield Waters and Why They Should Be Controlled

Aug 11, 2020 10:15:00 AM / by De Nora posted in oil and gas, oilfield, disinfection, produced water treatment, produced water recycling

Oilfield bacteria are present everywhere water can be found in the hydrocarbon production process. Unchecked bacteria populations can result in operational issues through the upstream and midstream production environment. Starting at the producing formation itself, bacteria introduced into the formation during drilling, completion, or flooding can result in the plugging of the formation as well as the wellbore.
