Experiment Protocol Chemical Engineer in Spain Madrid –Free Word Template Download with AI

Prepared by: Lead Chemical Engineer, R&D Division
Facility: Advanced Process Engineering Laboratory, Madrid Campus
Regulatory Framework: Royal Decree 486/1997 (Chemical Agents), REACH Regulation (EC) No 1907/2006.

The primary objective of this experiment protocol is to evaluate the catalytic efficiency and thermal stability of novel zeolite-based catalysts under high-pressure conditions within a fixed-bed reactor. This study is conducted by the Chemical Engineer team to enhance the yield of light olefins from heavy hydrocarbon feedstocks, aligning with the European Green Deal's sustainability targets.

Specifically, this protocol aims to:

• Determine the conversion rates of n-hexane at varying temperatures (400°C - 600°C).
• Analyze the selectivity towards propylene and ethylene production.
• Assess the deactivation rate of the catalyst due to coke formation over a 100-hour run.
• Ensure all experimental procedures strictly adhere to the safety standards mandated by the Spanish Ministry of Employment and Social Security.

Given the hazardous nature of the chemicals and high-energy conditions involved, strict adherence to safety protocols is non-negotiable. As this experiment takes place in Madrid, Spain, all operations must comply with local and national regulations.

The following regulatory frameworks apply:

• Royal Decree 486/1997: Establishes the minimum health and safety requirements for the protection of workers against risks related to chemical agents. All personnel must consult the Safety Data Sheets (SDS) for n-hexane and the zeolite catalyst prior to entry.
• REACH Regulation: Ensures the registration, evaluation, authorization, and restriction of chemicals. All waste generated must be cataloged and disposed of according to REACH guidelines.
• Local Madrid Protocols: In the event of a chemical spill or fire, the emergency response plan must be activated immediately, contacting the Madrid Emergency Services (112) and the facility's internal safety officer.

The Chemical Engineer must verify the calibration and integrity of the following equipment before initiating the experiment:

The Chemical Engineer shall execute the following steps in strict chronological order:

4.1. Preparation and Loading

1. Inspect the reactor vessel for any signs of corrosion or mechanical damage.
2. Load 50g of the HZSM-5 catalyst into the reactor bed, ensuring uniform distribution to prevent channeling.
3. Seal the reactor and perform a leak test using nitrogen at 5 bar pressure. Monitor for pressure drops over 30 minutes.

4.2. Purging and Heating

1. Purge the system with nitrogen at a flow rate of 50 mL/min for 60 minutes to remove residual oxygen and moisture.
2. Initiate the heating program. Ramp the temperature from ambient to 400°C at a rate of 5°C per minute.
3. Maintain the temperature at 400°C for 2 hours under nitrogen flow to activate the catalyst.

4.3. Reaction Phase

1. Introduce n-hexane feedstock via the liquid feed pump at a rate of 1 mL/h.
2. Set the reactor pressure to 10 bar using the back-pressure regulator.
3. Allow the system to reach steady-state conditions (approximately 2 hours).
4. Begin sampling the effluent gas every 15 minutes for Gas Chromatography analysis.
5. Gradually increase the temperature in increments of 50°C (450°C, 500°C, 550°C, 600°C), holding each temperature for 24 hours to assess thermal stability.

4.4. Shutdown and Cooling

1. Stop the n-hexane feed and switch back to nitrogen flow to purge hydrocarbons from the reactor.
2. Allow the reactor to cool down naturally to below 100°C before opening the vessel.
3. Collect the spent catalyst for post-reaction analysis (BET surface area and TGA).

The Chemical Engineer is responsible for processing the data obtained from the Gas Chromatograph. Key performance indicators (KPIs) to be calculated include:

• Conversion (X): The percentage of n-hexane reacted.
• Selectivity (S): The ratio of desired products (propylene/ethylene) to total products formed.
• Yield (Y): The product of conversion and selectivity.

All data must be recorded in the laboratory's digital management system. A comprehensive report detailing the experimental conditions, results, and deviations must be submitted within five business days. This report will serve as a basis for scaling up the process in industrial facilities located in the Madrid region.

In accordance with Spanish environmental laws, all waste generated during this experiment must be segregated:

• Liquid Waste: Collected in labeled containers for organic solvents.
• Spent Catalyst: Treated as hazardous waste due to potential metal contamination.
• Gas Emissions: Monitored to ensure they do not exceed the limits set by the Community of Madrid environmental agency.
