GONZALES, La. (AP) — A Louisiana-based industrial services company has bought a Mississippi petrochemical maintenance business with international offices.

Specialty Welding and Turnarounds LLC of Gonzales has acquired Hydroprocessing Associates LLC for an undisclosed price, The Advocate of Baton Rouge reported.

Both companies have offices in California and Texas. Hydroprocessing Associates also has offices in Washington state, Germany, Singapore and Brazil.

Hydroprocessing Associates, based in Moss Point, Mississippi, is the first acquisition since New York private equity firm Orix Capital Partners bought a majority stake in Specialty Welding and Turnarounds in January.

Hydroprocessing Associates was founded in 2005 to service petrochemical plant catalysts and reactors. Customers include Chevron, BP, Citgo, Phillips 66 and Exxon Mobil. The company has at least 65 employees, according to its LinkedIn profile.

The deal includes subsidiary Breathing Systems Inc., which makes helmets to keep safety inspectors safe from airborne hazardous chemicals.

Specialty Welding and Turnarounds, with more than 200 employees and 4,000 contract professionals, works in 14 states.

“We will now be able to provide high quality catalyst-handling services,” CEO Johnny Holifield said in a statement.
