A combination of factors in recent years has led to increased attention to water management in the oil and gas industry. Some of these factors include: limited water resources in certain areas, development of water-intensive technologies to better exploit unconventional plays, excessive transportation/disposal costs for water, a changing regulatory environment and a public push for sustainability and conservation relating to water as a resource.

There are a number of factors that affect the capacity and operation of a typical amine system. Solid or liquid contaminants in the system may cause foaming. The presence of foaming is typically addressed by the addition of expensive antifoam chemicals and/or by reducing the operating capacity of the amine system. In addition to this, the presence of contaminants in the system can foul heat exchangers and column packing or trays. These solid and liquid contaminants are either ingressed into the system with the feed stream, or generated within it as a result of the chemistry of the system. These contaminants are typically addressed by means of particle filters and carbon adsorption.

Natural gas gathering systems deliver large volumes of gas via pipleline to the central inlet of the gas processing facility. Removal of solid contaminants and free liquids present in the inlet gas is critical to the downstream process. Iron oxides, iron sulfides, dirt and other deformable particles can flow into the processing system. Effective removal of these contaminants is needed to prevent fouling. Pentair Porous Media technologies will help with a clean, natural gas feed, reducing upsets and associated downtime and increase productivity, lowering capital costs with fewer change-outs.

Deepwell facilities for the disposal of plant waste streams often employ nominally rated spray spun elements, bags, diatomaceous earth filters, and various other types of conventional filtration technology. These labor intensive systems provide protection of the well from occlusion by suspended particle matter, albeit often with high operational cost and limited assurance of reliable fluid quality. The ongoing challenge facing a deepwell system is the requirement that the formation into which the waste is being pumped must maintain its porous nature in order to operate effectively. Therefore, reliable, effective filtration to capture particles with the potential to plug the formation is critical. Pentair Porous Media’s proven advanced separation technologies have been employed in deepwell disposal systems to enhance system reliability, assure well integrity and lower operating costs and system maintenance.

Proper fluid and proppant placement are critical to a successful propped fracture stimulation treatment. Despite effective placement of the treatment, well performance is often detrimentally affected by incomplete gel breaking and fluid recovery.

Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economic means of water removal from these streams.Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and tetraethylene glycol (TREG). TEG is the most commonly used glycol in industry.

Many lube oil recovery processes create aqueous and hydrocarbon emulsions that are difficult to separate by means of conventional liquid/liquid separations technology. Accomplishing the desired separation requires that these emulsified droplets be captured. Conventional coalescers are unable to provide the degree of brightness and clarity associated with good separation due to the inability to capture and remove the most penetrating droplets that indicate carry-over. Pentair Porous Media technologies have been developed to address the inherent deficiencies of the conventional coalescers.

The key to optimizing a hydroprocessing unit is to maximize the life of the catalyst bed and increase energy efficiency of the furnaces. Our goal is to eliminate fouling of the catalyst bed by particles and aqueous fluids and the dissolved components within them as well as fouling of hydrogen recovery membranes and furnace-burner tips.

Purify benzene, toluene, and xylene (BTX) from refinery or petrochemical aromatics streams such as catalytic reformate or pyrolysis gasoline. This liquid-liquid extraction processes offers lower capital and operating costs, simplicity of operation, range of feedstock, and solvent performance

Hydrocarbons in the sour water system are typically present on a continuous basis at up to 10,000 ppm and during upsets to levels greater than 50,000 ppm. As little as 5,000 ppm Cat Naphtha lost to the sour water system from an FCC main fractionator overhead accumulator operating at 100 gpm water represents 262,800 gallons of potential product gasoline lost per year, with a recoverable product value greater than $500,000.
