Clariant's CATOFIN® Technology drives world's largest propane dehydrogenation unit

New 600 kta Propane Dehydrogenation (PDH) unit on-stream in November 2013---- New unit exceeded nameplate capacity in the first month of operation---- First PDH unit operating in China

Muttenz, January 16, 2014 – Clariant, a world leader in specialty chemicals, announces that the largest PDH unit has begun production in Tianjin, China, using CATOFIN® technology. This 600 kta unit is also the first PDH unit in China. It uses the CATOFIN process and catalyst, a technology that is licensed through CB&I.


The Bohua unit exceeded nameplate capacity in the first month of operation, illustrating the stability and ease of operation that is characteristic of CATOFIN units worldwide.

Clariant recently completed a capacity expansion for these high performance catalysts at its site in Louisville/Kentucky, USA. Demand for CATOFIN catalysts has grown rapidly in recent years as shale gas growth has created increased demand for on-purpose propylene production. In China, high demand for polypropylene and other propylene derivatives has boosted PDH interest. Several new CATOFIN production units will begin production in China in the next 12-18 months.

CATOFIN technology and catalysts correspond to a reliable and less complex production process for on-purpose olefins/butadiene production with efficient energy consumption. New generations of catalysts with significant performance improvement have been commercialized successfully in the last few years. CATOFIN technology has been selected by 34 licensees worldwide and is in operation in 12 units today.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
