Decoking and Pigging Services
Clean Harbors Decoking and Pigging Services provides a safe and environmentally friendly approach to the removal of pipe deposits. The closed loop pigging process uses a high volume, low pressure water pumping system to propel our patented bi-directional pigs through pipes and coils to effect cleaning. Pigging removes all deposits left on the tube wall, improving thermal efficacy and extending run lengths. The operation is safely controlled from the unit’s control room where flow rates and pressures are closely monitored. Progressively larger pigs are run until all of the deposits are completely removed, and no hazardous chemicals are used during the pigging process.Chemical Cleaning
Clean Harbors Chemical Cleaning Services are an efficient, cost-effective way to remove corrosion, deposits, residual oils/greases, and other obtrusive contaminants from tainted surfaces. This process is used for passivation to eliminate fouling, oxidation, process system corrosion, and decontamination of process lines and vessels.Industrial Vacuuming
Clean Harbors Industrial Vacuuming Services offer versatility in removing dry or wet materials, drastically reducing clean-up time compared to conventional shoveling and loading procedures.Onsite Dewatering Services
Surface impoundments and storage tanks containing built up sludge can limit the effectiveness of your wastewater treatment system. Clean Harbors can safely remove and process the sludge and reduce the volume of waste through the use of specialized dewatering and dredging equipment. This results in improved efficiency of your wastewater treatment system and significant cost savings for you. All our systems are mobile and allow for timely set up upon mobilization for small to large scale dewatering projects.Catalyst Technologies
Clean Harbors Catalyst Technologies is a global full-service catalyst loading company. For more than three decades, we have been helping refineries and chemical and petrochemical plants around the world improve their bottom line by eliminating unnecessary downtime by providing all phases of catalyst change out. We remove and replace spent catalyst from process vessels within the refining, chemical and petrochemical industries. Services include inert entry into confined spaces, catalyst screening and segregation of materials. Our trained professionals are focused on safety and customers and utilize equipment and processes to do the job right, any where, any time.Dust Control Services
Clean Harbors Dust Control Services capture and contain airborne catalyst dust particles created during catalyst unloading and loading activities. Catalyst dust can have high concentrations of noble metals such as nickel, cobalt, and molybdenum, or precious metals including silver, platinum and rhenium. Most of these metals have considerable reclamation value to a refinery. Our systems protect personnel from dust particles and metals that are potentially harmful if inhaled while working in and around an area where catalyst is being handled. Clean Harbors dust control services safely and efficiently capture these materials for reclamation or disposal.High Temperature Salt Transfer, Storage & Melting
Clean Harbors Catalyst Technologies provides safe handling of high temperature molten salts (sodium/ potassium nitrates/ nitrites) to the petrochemical and solar power industries. Services include melting, transferring, storing and decanting of blended sodium/potassium nitrate/nitrite materials.Passivation Services
Clean Harbors uses CATnap, an exclusive technique for quick and safe unloading of catalysts from petroleum processing units. The CATnap process allows the spent catalyst to be removed in an air atmosphere versus purging the reactor with nitrogen and performing inert entry. Unit shutdown time may be decreased by as much as 48 hours by reducing or negating the hydrogen stripping process. Elimination of dust during the unloading process increases productivity and health and safety in and around the reactor being serviced.Screening & Segregation Services
Clean Harbors’ screening units segregate spent catalyst and classify material size. Dust and fines from attrition created during the shipping and handling of catalyst are also removed. Our units can easily segregate and class four particle sizes in a single pass prior to loading. By screening the catalyst, broken pieces (chips and fines), which can increase pressure drop during reactor run operations, are removed. This is particularly important in situations where spent catalyst will be reused or in reactors with a history of severe operating runs. Our spent catalyst screening process also removes support material for reuse.
