A field engineering office was established to define tie-ins and establish piping routes. The remainder of the design work was completed by a task force in the Houston home office. The existing plant was used as a design model. Offsite piping and tankage service was changed to accommodate the onsite revamp work. The process service of each of the existing fractionators was changed. Trays in certain fractionators were replaced with packing. The sewer system and relief system were modified.
Reuse of existing piping and equipment was maximized.
Performing construction work in an active operating chemical plant required increased attention to industrial hygiene and safety. The project completed more than 700,000 hours without a lost time accident.
