Petrochemicals

Start with who needs plastics, resins and chemical building blocks and why. Around plastics converters, packaging makers and construction firms drive demand in Dubai, Abu Dhabi and the other emirates.

• List 10 offers or suppliers in the UAE with price per tonne in AED and who buys.
• Interview 5 people from plastics converters, packaging makers and construction firms: what do they buy now, how often, what do they pay, what annoys them?
• Learn three terms: Feedstock (the raw material fed into a plant); Specification (the written limits a product must meet to be sold); Batch record (the log of what was made, when and how).
• Write a one-page brief: user, need, hoped-for price, and the rule that matters most.

Activity. Complete the market table, five interview notes and the brief.

Standard to meet. Price ten offers, interview five users, and state one need in one sentence.

Know the rule before the work. Main hazards here: toxic release, fire and runaway reaction. Hazard thinking means list each step, ask what could go wrong, and decide the control.

• Ask your local authority or free zone which licence, permit or inspection applies. Write the answer and the date you asked.
• For each step (feed; react; cool and separate; then bag or tank the product) write the hazard and the control.
• Use a hierarchy: remove the hazard, replace it, separate people from it, change the way of work, then protective equipment last.
• Keep a one-page incident rule: who you call, what you stop, what you record.

Activity. Draw the flow and mark hazard and control at each step.

Standard to meet. Name a hazard and a control for every step, and answer the licence question in writing.

The work is a short chain: feed, react, cool and separate, then bag or tank the product. Learn each link, then link them with records.

• Write a checklist for each of the 4 steps: input, action, check, output.
• Time each step three times and note the slowest.
• Record a defect or delay each time it happens: what, where, cause, fix.
• Measure tonnes in specification per day; this is your main number.

Activity. Run the chain three times (simulated or real) and fill the log.

Standard to meet. Complete three logs, and give the slowest step a cause and a fix.

What you do not measure you cannot improve. Your main measure is tonnes in specification per day.

• Define tonnes in specification per day: what counts, what does not, and over what period.
• Draw a simple chart of the last 10 results and mark the average.
• Find the top two causes of loss with a tally sheet, then fix the biggest one first.
• Check measuring tools: are they accurate, clean and in date?

Activity. Collect a tally for one week and make a Pareto chart.

Standard to meet. Complete the tally, name the biggest cause, and plan one fix with a date.

Know the cost of one tonne before you set the price. Include materials, labour, energy, transport, licence share, waste and a safety margin.

• Cost per tonne = total cost divided by tonnes sold (not made).
• Margin = (price minus cost) divided by price.
• Break-even units = fixed costs divided by gain per unit.
• Test the price with two users and write down the answer.

Activity. Build the cost sheet with AED on every line and have your mentor check it.

Standard to meet. Check that no cost is missing, and calculate the margin twice by different routes.

Customers return when you keep promises. Promise only what your workflow can deliver.

• Write a one-page offer: what is included, what is not, price, time, how you fix mistakes.
• Write a short script for the first call or visit.
• Agree dates in writing; confirm each change.
• Handle a complaint in four steps: listen, apologise for the impact, fix, record what changed.

Activity. Present the offer to two users and note changes.

Standard to meet. Write an offer with scope, price, time and a fix rule, and collect comments from two users.

Small, real and recorded. Change one thing at a time and learn quickly.

• Keep a daily log: date, units, cost, delays, defects, safety notes.
• Hold a 15-minute review each week with your mentor.
• Write down every complaint and what you changed.
• Take photos only where allowed and never of people without consent.

Activity. Complete 30 days of the log and four weekly reviews.

Standard to meet. Log 30 days, give each defect a cause, and keep weekly notes.

A decision beats a feeling. Compare plan with result and choose to scale, change or stop.

• Make a before and after table: cost per unit, defects, delays, repeat users.
• Write three lessons.
• Decide scale, change or stop, with the numbers behind it.
• Give two peers one strength and one fix each.

Activity. Present to a review room and collect one written comment from a user.

Standard to meet. Justify the decision with numbers, and give two peer reviews.

Plants turn simple gases and liquids into building blocks, and then into plastics. Knowing the chain explains why one upset affects many products.

• Draw the chain from feedstock to a final plastic and name each intermediate.
• Heat, pressure and a catalyst decide how much product forms; each has a safe window.
• Side products are not always waste: some are sold or burned for energy.
• A change in feed quality changes everything downstream, so feed is tested on arrival.

Activity. Draw the chain for one plastic and mark where heat, pressure and a catalyst act.

Standard to meet. Label every step, write each safe window, and name the feed test.

A reaction that makes its own heat can speed up faster than cooling can follow. Pressure relief and interlocks exist for that moment.

• Know the signs: rising temperature with cooling at maximum, pressure rising faster than normal.
• A relief valve opens at a set pressure and sends gas to a safe place; it must never be isolated without a permit.
• An interlock stops the feed automatically if a limit is crossed; never bypass one without written approval.
• Practise the shutdown order on paper: stop feed, keep cooling, vent safely, call for help.

Activity. Write the shutdown order for a reactor and list which devices act at each step.

Standard to meet. Order is safe; no step relies on bypassing a protection.

Customers buy by property: how easily the plastic melts, how dense it is, how strong. Each lot carries a test certificate.

• Typical tests: melt flow, density, tensile strength, colour and moisture.
• Sample the same way every time: from several places, labelled and sealed.
• Compare results with the written specification; out-of-limit lots are held, retested and decided by the quality lead.
• Keep records for each lot so a complaint can be traced to the exact shift.

Activity. Fill a certificate for three sample lots and decide each as pass, hold or downgrade.

Standard to meet. Compare every result with a limit and explain the decisions.

On the slide: L1 Basic · From gas to plastic

Notes: Name a feedstock, a plastic made from it and the three hazards of toxic release, fire and runaway reaction. Notes: draw the chain on one page; no plant entry, and ask a supervisor before any visit.

On the slide: L2 Awareness · Safe windows and specification

Notes: Describe why heat, pressure and a catalyst each have a safe window and what a specification is. Notes: show a lot with a test result outside its limit and ask who may release it; the answer is the quality lead, never the operator alone.

On the slide: L3 Foundation · Draw the reaction chain with safe windows

Notes: Draw the chain for one plastic and mark where heat, pressure and a catalyst act, with a test for feed on arrival. Notes: work only under a competent supervisor; check every step is labelled and each safe window has a written number and unit.

On the slide: L4 Practitioner · Shut down a reactor on paper

Notes: Write the shutdown order for a reactor with stop feed, keep cooling, vent safely and call for help, and name the device acting at each step. Notes: use a rise of 3 degrees Celsius per minute with cooling at full; no step may rely on bypassing a protection.

On the slide: L5 Specialist · Decide pass, hold or downgrade

Notes: Evaluate three sample lots against written limits and decide pass, hold or downgrade with a reason. Notes: lot 114 reads 8.4 against a limit of 7.0 to 8.0 and retests at 8.3, so it is held and sold as a lower grade with the customer told; at AED 4,200 price and AED 3,600 cost a tonne gains AED 600, a margin of 14.3 per cent.

On the slide: L6 Advanced · Coach operators on records and interlocks

Notes: Lead a team in keeping complete batch records and in never bypassing an interlock without written approval. Notes: sample five batch records a week against a checklist; any bypass without approval is a stop-and-report event.

On the slide: L7 Super expert · Design the quality and safety system

Notes: Design a feed test, batch record, relief and interlock check system for a plant, with an audit and a 12-month plan. Notes: trace three complaints to the exact shift to test the records; present one risk, one saving per tonne in AED and a review date for each protective device.
