CHAPTER No.11 HAZOP STUDY INTRODUCTION A HAZOP survey is one of the most common and widely accepted methods of systematic qualitative hazard analysis. It is used for both new or existing facilities and can be applied to a whole plant‚ a production unit‚ or a piece of equipment It uses as its database the usual sort of plant and process information and relies on the judgment of engineering and safety experts in the areas with which they are most familiar. The end result is‚ therefore reliable

and its feed throughput is 29‚500 BPSD. RFCC LPG Merox consists of a pre-treatment section‚ an extraction section and caustic regeneration section. Propylene Recovery Unit (Unit 2700) The purpose of Propylene Recovery Unit (PRU) is to recover polymer grade propylene from C3/C4 mixture of the RFCC unit. The recovered polymer grade propylene is to be used as the feedstock for a Polypropylene plant‚ which will be constructed next to the Refinery. PRU is designed to process 29‚368 BPSD of a mixture

of polypropylene‚ which is a polymer known for its strength and malleability. Merseyside is where the production of polypropylene pellets begins. These pellets are refined gas received in tank cars known as propylene. In the first stage of the production process‚ polymerization‚ the propylene gas was combined with diluents in a large pressure vessel. The second stage produces a finished plastic which is extruded into pellets for shipment to the customer. There are two plants that produce polypropylene

An addition polymer made from the monomer propylene‚ it is rugged and unusually resistant to many chemical solvents‚ bases and acids. Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene

but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Most plastics are derived from propylene‚ a simple chemical component of petroleum. When heated up in the presence of a catalyst‚ individual chemical units monomers of propylene link together by forming extremely strong carbon-carbon bonds with each other. This results in polymers long chains of monomers called polypropylene. This content of plastic makes

Petrochemicals prices climb 2% in December on tight supplies LONDON‚ January 9‚ 2013 - Prices in the $3-trillion-plus global petrochemicals market climbed 2% to $1‚350 per metric ton (/mt) in December‚ according to the just-released monthly average of the Platts Global Petrochemical Index (PGPI)‚ a benchmark basket of seven widely used petrochemicals. This follows a drop of 2% in November. But on a year-over-year basis‚ petrochemical prices were up 16% from the December 2011 average price of
