Process Modules

TOZZI acts both as EPC contractor and Process Solutions Provider in the Oil & Gas field. Since the very beginning, we have provided innovative services mainly in the gas conditioning field. We can claim a few records along the way:

  • The largest gas dehydration plant in the world (up to year 2009)
  • The highest gas dehydrating pressure on FPSO (2007)
  • The first REDOX process unit on FPSO (2013)

TOZZI has extended its know-how and expertise to the oil field as well, and is today widely recognized as one of the companies having designed process units with the widest operating conditions range. In addition to this, we have the structure and experience to implement various types of contracts and multiple projects simultaneously. Our scope of supply ranges from process design packages to turnkey plants, with TOZZI acting either as an independent main contractor or in joint venture with other companies on a project-to-project basis. The best of two worlds stands at Clients’ disposal: the flexibility of responding to all needs, coupled with the problem-solving capacity of a skilled and fully trained staff.
