The Lula oil field off the coast of Brazil is considered one of the largest oil discoveries in recent years. It was brought into production using FPSO (Floating Production Storage and Offloading) platforms. EagleBurgmann supplied the GE compressors at the Tupi 4 floating production site with new and innovative ultra-high-pressure DGS for gas re-injection.
Purified Terephthalic Acid (PTA) is particularly a preliminary product used in the polyester and PET production. It is generally produced from naphtha. EagleBurgmann supplied its largest agitator seal to a PTA facility in China, and since then has become a leading manufacturer for PTA production.
Reliability during sensible chemical reaction processes and a significantly increased lifetime characterize the agitator seal used in a chemical production plant. In stirred tank reactors of a polymer dispersion facility in Germany, various monomers and water are transformed into polymers. EagleBurgmann HSHLV-D agitator seals are used in these reactors to prevent standstills.
In a refinery, different systems are being used, among them multistage vertical can pumps to circulate highly flammable liquid hydrocarbons. EagleBurgmann Nova Magnetics provided several magnetic couplings to hermetically seal them.
In a chemical plant in Japan, a pump is used to transport molten sulfur. Crystallized sulfur in the area of the shaft seal led to contamination and enormous maintenance costs. Since retrofitting to the EagleBurgmann SulfurAce mechanical seal the pump offers optimal availability. The working environment is clean and employees are secure from hazardous substances.
The Conoco Humber refinery in England processes up to 230,000 barrels crude oil per day. To ensure a trouble-free thermal cracking process, the refinery uses EagleBurgmann's dual metal bellow seals.
The Sohar refinery was built with state of the art technology to process a mixed feedstock of crude oil and atmospheric residue. Within the scope of its TotalSealCare service, EagleBurgmann maintains an own service center to immediately cater to the needs of the customer.
Constantly changing operating conditions place extreme demands on pump seals in the production of antibiotic active ingredients. DiamondFace technology significantly extends the life of seals and enables the reduction of stock costs through rationalization.
For the export compressor in a gas processing plant, EagleBurgmann developed a sealing solution that is more than just reliable. Low nitrogen requirement and minimal methane leakage reduce operating costs by a five-figure amount.
In processes with crude oil, seals in pumps are exposed to high temperatures and wear caused by solids. The safety standards are high to protect the environment and personnel from leaking media. EagleBurgmann developed a robust solution with reliable safety properties for a refinery.
An FSPO unit is equipped with power generation and waste heat recovery systems from different manufacturers. The correspondingly disparate expansion joints failed after a short time. EagleBurgmann supplied a low-maintenance solution that is now part of the standardized equipment of other FPSO units.
With a strategic alliance between EagleBurgmann and the Alliance Pipeline, which leads from British Columbia and North Dakota to Chicago, best practice methods for maintenance and availability were to be implemented. EagleBurgmann PDGS seals are installed in the pipeline's compressor stations.
In a natural-gas processing plant in Australia, moisture and dirt directly infiltrated the compressor seal via the supply gas. The operating conditions could not be changed, but the seal certainly could.
Extra-heavy crude oil, sand, produced water and gas are the "living conditions" for the seals in a multi-phase pump in Venezuela. EagleBurgmann developed a solution that proved to be extremely robust despite a multiphase fluid and considerably less flush fluid.
EagleBurgmann convinced the persons responsible for the liquor line in a pulp mill to equip the shaft of the pressure disk filter with a practical and reliable mechanical seal, thereby increasing the MTBR to an extraordinarily long period of three years.
The handling of latex is a major engineering challenge for the mechanical seals that are used on pumps and reactors. One of the German EagleBurgmann service centers collaborates with the operator of the Marl Chemical Park, and has been supplying it with individual sealing solutions for many years.
TA-Luft and ATEX requirements make it necessary for operators to replace all seals used that are not conform to the standards. At Chema Prozess- and Systemtechnik in Germany, EagleBurgmann equipped steel distillation vessels with double mechanical seals in cartridge design that meet the needed legislations.
