In 2015 we sold off the assets of a former 500,000 tpy Purified Terephthalic Acid (PTA) Plant located in the United Kingdom. Purified terephthalic acid or PTA as it is also known as is a middle material produced from Paraxylene and is a feed stock for synthetic fibers, Polyethylene terephthalate (PET) bottle resin and polyester film.
The PTA plant was commissioned in 1981, shut down in 2014 and licensed INVISTA technology. In recent years the plant had undergone some significant upgrades in particular, a new rotary steam tube dryer was installed in 1999, a MAN Turbo steam condensing turbine and Sundyne high pressure pumps in 2004, a DURR regenerative thermal oxidiser in 2005 and a catalyst recovery plant was installed in 2007.
Other major items of equipment include: titanium lined oxidation reactors, stainless steel and titanium lined crystallisation reactors, hydrogenation reactors, rotary vacuum filters, rotary steam tube dryers, decanter and separator centrifuges, high pressure centrifugal pumps, stainless steel and GRP storage tanks, stainless steel mixing vessels and much more.
