Committed to Responsible Care ® 21 employees around the world dedicated to RC activities Commercial Offices: Hong Kong, Brussels, Dallas, Santiago Tokyo, Shanghai, Seoul, Billingham, Dubai Shipping Subsidiary: Waterfront Shipping Manage fleet of ~20 vessels Methanex Corporation Overview
5
METHANOL (Methyl Alcohol) Clear, colorless liquid Made up of carbon, hydrogen and oxygen CH3OH What is Methanol ? Chemical formula
6
How is Methanol produced ?
7
Methanol is... Produced from natural gas and coal Diversified end uses Formaldehyde Acetic Acid MDF, Plywood Fleece, Adhesives, Paints Dimethyl Methyl Chloride Terephthalate Silicones Recyclable plastic bottles Emerging Energy Uses (High Growth Potential Markets) Traditional Uses (Mature Markets) DME (dimethyl-ether) Fuel Blending Where is Methanol used ?

The Methanol House
9
Flammable, burns with clear, low heat flame Difficult to see during daylight Soluble in water, miscible in alcohol, ether and to most organic solvents. Low solubility in fats and oils. Concentrations of methanol in water above 25% are flammable Flash point (°C): 11 -12 Lower Explosive Limit (LEL) (%): 6 Upper Explosive Limit (UEL) (%): 36 Autoignition Temp (°C): 385 Boiling Range(°C): 63.9 – 65 Properties of Methanol
10
Melting Range (°C): -97.8 Specific gravity (water=1): 0.79 @ 20°C Biodegrades quickly in small amounts Readily absorbed into the body Poisonous in liquid or vapours state Toxic: danger of very serious irreversible effects through inhalation, contact with skin and if swallowed Properties of Methanol
11
NFPA Methanol 3: Risk of flammability: You can ignite at ambient temperature 1: Risks to health: Slightly dangerous 0:: Risk of reactivity: Stable Remember Methanol is: FlamableToxic Methanol Handling
12
Flame geometry and thermal radiation from methanol pool fires in 5.85 metre diameter bunds. Pool being filled Methanol Handling Full-scale Pool Fire test carried out at Spadeadam test site in Cumbria, UK on 9 March 1993

Ignition! Methanol Handling
14
Colorless flame - just a heat haze. Wind speed was 4.4 metres/second (10 mph) ambient temperature was 4.5°C, pressure 981 millibar Methanol Handling
15
Safety precautions No smoking Vehicular access Intrinsically safe equipment Grounding all equipment, pumps, tanks, pipes,vessels, filters
16
Extinguishing Media Alcohol stable foam Dry chemical powder Carbon dioxide Water spray or fog - Large fires only. Methanol Handling Fire Fighting/Explosion Hazard May be violently or explosively reactive Severe fire hazard when exposed to heat, flame and/or oxidizers Vapor may travel a considerable distance to source of ignition

Detector tubes Electronic Instruments Absorbent tubes Biological Monitoring How do we detect Methanol? Methanol Handling
22
Safe Methanol Handling Personnel and Environmental protection Process side Closed sampling / dip / temperature measurement on the Methanol Storage Tanks Routine samples using closed cylinders Tandem seals on all methanol pumps Flame detectors and sprinklers on all methanol pumps Closed methanol drainage system AAAF foam for methanol fire fighting Methanol tanks fully bunded and controlled drainage Methanol vapors recovery system on all methanol tanks and from the ships Process Side: Safe Methanol Handling
23
Methanol Truck Loading Automatic stop logic if high truck level Foam-water monitors Dedicated tanks Safety induction to the driver and certification Grounding and interlock Dip loading pipe, and others Methanol Ship Loading Loading arms provided with an Emergency Release System Spill and drains containment pumped back to the plant Foam-water monitors Grounding and interlock, and others Process Side: Safe Methanol Handling

Plant Fire Fighting System Fire Water / Foam System. 1.Filtered Water Tank used as fire water supply 2.Fire Water Jockey pumps 1P-4401 A/B, Diesel pumps 1P-4402 A/B/C/D. 3.Fire Water Jockey / Diesel pumps P&ID. 4.WATER / FOAM DELUGE SYSTEM. 5.Water Deluge SYSTEM. 6.Heat detectors and Gas detectors 1.Dry Chemical Powder System 2.Fire truck (water, foam, dry chemical) and portable Extinguishers of various types at strategic locations FF irewater is supplied to the plant via a ring main system of piping. The northern portion of the ring main protects the methanol storage tank area and the southern portion of the ring main protects the methanol production area, utilities, and buildings. FF irewater supply is from the Filtered Water Tank
