AN COMPANY - petroval.com

1 Created in 1990, PETROVAL s headquarters are based in Le Havre (France) close to the TOTAL and EXXONMOBIL refinery production plants in that its success in new geographic markets required an on-the-ground operation, PETROVAL began building foreign business, firstly in Houston Texas (USA) in 2003, in Singapore in 2011 and in Bahrain in , PETROVAL operates in more than 50 countries on a worldwide INTERNATIONAL COMPANYC reated in loading over 40 000 tons of catalyst per year Research and Development technologies with TOTAL (TOTAL licenses & Petroval patents).Highly skilled personnel (with a full understanding of refining and petrochemical processes).New office in Bahrain in in 1990, PETROVAL introduced and became the world leader in terms of dense loading technologies and services by launching to the refinery market the first generation of DENSICAT machine, its most important product at that technology was remarkably advanced and superior compared to other technologies on the market and quickly became a recognized success.

2 It helped fund PETROVAL s rapid growth not just into new services and product lines but also opened up new markets around the world. In the years following the DENSICAT introduction, PETROVAL has made its mark in several new activities such as tube inserts (1993), infrared thermography (2006) and catalyst unloading & loading expertise. The COMPANY also strengthened its existing activities by launching the DENSICAT second and, third generation machine, building on its strong reputation and success in the refining and petrochemical , PETROVAL is the leading and pre-eminent COMPANY in terms of dense loading technologies and optimization of reactor Thermal and Catalyst departments are the two strategic business areas of services and products are more and more successful with new advanced technological products being regularly launched onto the market.

3 PETROVAL is moving forward with a promising and bright future with key licenses and COMPANY BUILT ON INNOVATIONA PROUD HISTORYOUR BUSINESS STRATEGYF orward-thinking technology focused on: Answering customer s needs by finding expert solutions to catalyst handling and unloading / loading issues and by providing professional service and advice in thermal activity. Optimizing reactor process and performance by developing new technologies. Creating and designing innovative products (forward-thinking). Anticipating changes and proposing level services focused on: Strong relationship with refiners, handling companies and catalyst suppliers.

4 Supervision, sampling, inspections and advice made on site. Detailed reporting with analysis and customers satisfaction focused: A highly motivated and experienced team engaged exclusively by PETROVAL, resulting in a high quality response 48 hours mobilization to anywhere: A flexible team able to arrive on site for technical assistance at short notice. SAFETY & QUALITY safety first zero accidentSAFETY FIRST & ZERO ACCIDENTPETROVAL places the highest priority on safe working practices and conditions. In all cases if a hazardous situation is observed it will be immediately reported and action taken to resolve any sets up a procedure of requirements to ensure that conditions on site are in line with: Modern best practices, based on experience.

5 Most recent incident recommendations and reviews, collected from a wide range of sources, including clients, employees feed-back, published literrature and legislation in various safety and quality management systems are continually reviewed and improved to meet ISO & local safety standards. TRAINING HIGH SAFETY SKILLS TO WORK UNDER INERT ATMOSPHEREP ersonnel certified for all catalyst operations under inert atmosphere. Specific inert entry training for all our personnel working in an inert environment on a worldwide basis. Active participation in task force analysis for work in inert conditions, attending full training programs, technical meetings, including equipment tests and evaluation and review of entry procedures on an annual basis.

6 Certified by all catalyst handling companies to operate under inert atmosphere using their life support system. OUR TEAM SAFETY PROCEDUREI nternationally recognized standard for Quality Management Systems. CATALYST SERVICED ifferent loading methods, such as sock loading or dense loading techniques, can be applied according to reactor process. In general, dense loading is the preferred method as it ensures the increase of the catalyst loaded and thus improves performance of the reactor due to better is licensed for the following dense loading techniques: DENSICAT , DENSICAT New Generation and CATAPAC .Additional to these certified machines, PETROVAL provides experienced TECHNOLOGYWHY TO USE DENSICAT DENSE LOADING ?

7 WHY TO CHOOSE PETROVAL ?HIGH QUALITY LOADING Maximum achievable density guaranteed (based on lab test results). Continuous assessment with respect to the maximum density value at all times. Respect of the maximum loading rate of four metric ton/m2 per hour. No catalyst attrition with the DENSICAT technology (particles slide on the whips). Higher homogeneity of the catalyst bed thanks to optimized catalyst distribution. FASTEST LOADING RATE Fastest instantaneous loading rate to minimize the duration of the dense loading rate defined by windows opening on the DENSICAT equipment and irrespective of the rotation QUALITY SERVICE Trained and certified DENSICAT specialists employed by PETROVAL and loading more than 40,000 tons of catalsyt per year.

8 Reactors loading diameter from to meters (including tubular reactor). Strong client response on a worldwide basis thanks to PETROVAL s international LOADERS USING THE CENTRIFUGAL FORCEDENSICAT LOADING DISTRIBUTIONINSTANTANEOUS LOADING SURFACE30% - 40%100%HOMOGENEITYL imited loading distribution: Less homogeneous catalyst bedMore homogeneous loading distribution: Catalyst bed more homogeneousLOADING SYSTEMC atalyst ejected through a distribution loaded through a barrel by gravity and spread by FORCE AND CATALYST SEGREGATIONC atalyst ejected from a distri-bution tool: Ballistic separation by virtue of centrifugal force = Catalyst segregation (smaller particles loaded in the middle and bigger particles at the walls)Catalyst not ejected from a distribution tool.

Dense loading time LOADING OPERATORSC ompanies certified by licen-sors / Limited number of full time employed operators. Specialised team of 30 trained and certified experts (engineer le-vel) directly employed by Petroval. The catalyst loading is their full time job on a world wide DENSICAT PREMIUM SERVICE includes dense loading and reactor expertise. In this case, PETROVAL provides close supervision of all activities inside the reactor to ensure the following: Quality of the full loading of the reactor (sock and dense).

10 Full supervision of the loading and mechanical operations (including the closure of the unloading nozzles, transfer tubes, distribution trays, quench pipes and grid sections, ensuring all internal components are correctly positioned and sealed). Tests on the catalyst and inert balls. Validation of the loading diagram and compliance with expected densities. Detailed report, loading details, analysis and proposal of improvements. Highly qualified supervisors. Guarantees on trouble-free start-up and operation of the acting as a third party supervises each and every step of the catalyst loading, ensuring a state-of-art loading with close attention to safety and quality: PRIOR TO THE LOADING: PETROVAL reviews all planning details, conducts tests on all loaded catalyst and inert materials, validates loading diagrams and conducts inspection of the internal components and cleanliness of the THE LOADING.
