Preliminary Risk Analysis Tecnique for the Design of a New Refinery in Brazil

This work will be presented the technique of Preliminary Risk Analysis used during the design of a new oil refinery in Brazil. The technique of preliminary risk analysis involved in process flow of all major units of equipment and process of transfer and storage facilities in a manner similar to that achieved during the approach of HAZOP. As a result of the application of the preliminary risk analysis were generated recommendations for:

a) Layout;

b) design of systems: detection and alarm of toxic gases and vapors and flammable;

c) installation of lock valves of large inventory of toxic and flammable;

d) installation of check valves;

e) Network of water from fire;

f) monitor fixed electric Cannon, Cannon monitor fixed self oscillating, Cannon monitor fixed;

g) Location and number of hydrants;

h) Position and quantity of fire extinguishers;

i) steam applicators;

j) sprinklers;

k) position and number of lines of supply of foam applicators;

l) Drainage;

m) Fireproofing of metal structures and equipment

n) Protection against passive conduit for fire and eletrocalhas;

o) Cabinet Fire Fighting;

p) indicators of direction and intensity of winds;

q) shower and emergency eye-wash

r) routes of escape;

s) access to people;

t) Access for vehicles;

u) Individual Protection Equipment;

v) Trigger manual emergency alarm;

w) device alarm visual / sound;

x) Safety valves and relief of pressure;

y) protection vacuum valves;

z) Cut-flame;

aa) Position and type of samplers;

bb) Position and quantity of the Mouth of access doors and cleaning;

cc) dikes sizing of tanks;

dd) normal and emergency lighting;

ee) Closed Circuit TV;

ff) Ports of explosion of furnaces;

gg) analysis of exhausted gases in furnaces and incinerators;
