Laboratory Activity

Some members of Yekta Group were employed in the laboratories of Iranian crude oil refineries from the very beginning and gained a lot of experience in laboratory activities and analysis of crude oil and gas condensate and petroleum products and gases and chemicals, quality control.

Experiments that lasted 30 years and now the results of each type of experiment are properly analyzed. In addition to these experiences, they have sufficient knowledge of laboratory equipment and are very proficient in their use and sometimes perform their repairs :


1- Quality Control laboratory: In each shift(per 12 hour : DAY/NIGHT) , many standard specifications of semi finish  & finish  petroleum products and crude oil, operation units and storage finish tanks by technicians  are controlled. About : specific gravity@60 F , Dencity @15 C , flash points , pour point  , distillation , colour , water content , loss , mercaptan , odour , residue , copper corrosion  , RVP,VI , RON , MON , kinematic viscosity, sediment , softening point , cetane index , smoke point , penentration are all tests at quality control laboratory are tested.



2- Special laboratory: daily performance, aircraft fuel specifications, Jet fuels  & ATK ,JP4 ,...& weekly important ASTM ,UOP,BS, DIN methods tests.about : ASH , WSIM ,TBN ,TAN , NOACK , JFTOT, sediment , CR( conradson ) , CR ( %10 rams bottom) , vacuum distillation ,total sulphur, karl fischer , aromatics , olefin , calorific value , ductility , gum content , induction period , benzene , total nitrogen , heptane solubility , freezing point , particulates , water reaction , aniline point , conductivity , FOAM , Air release , dielectric , filter pressure , silver corrosion tested.

3- Water laboratory: During the day, the condition and specifications of the water entering the refinery & utility  plant waters.
4- Solubilization Laboratory: The solutions used in the experiment are made with ASTM methods for tests In this laboratory, the necessary solutions for all PETROLEUM tests are made as standard and according to the ASTM methods.
5- Gas laboratory: During the day, samples of Natural Gas, LPG and the like with GC .About : appearance,H2 content, C1 content, C2 content, C3 content, nC4 content, iC4 content, penthane, H2S,mercaptan,Dencity,Odorizing agent are tested.

Laboratory activities, oil and lubricants are an important part of Yekta Group's years of management experience. Valuable activities in oil laboratories of Tabriz , Tehran , Shazand Arak & Bandar Abbas  crude oil refineries.

Development of current standards in each activity has created powerful treasures regarding oil laboratory knowledge, interpretation and technical analysis of any industrial and automotive oils analysis in Naft Andish Yekta ( yekta oil & gas ) PTE  JS Company.

It is necessary to mention, regarding the activities of the oil laboratory, that mastering the affairs and the process and conducting oil and gas tests and quality control is the result of at least 15 years of increasing efforts and studying valid international standards, so that the company's experts are among the technical judges in this regard in the country.



Yekta company dominates all specialized laboratory units (including; crude oil - hydrocarbons - lubricants - bitumen - grease and antifreeze laboratories), active training unit in the field of crude oil and petroleum products and operational research unit (technical - engineering and R&D) is:


1- Testing of crude oil, gas condensate, petroleum products (gasoline, diesel, kerosene, solvents, motor oil, gear, hydraulic, industrial, grease, bitumen, etc.)

 2- Practical and theoretical training to get familiar with all types of petroleum products, related practical tests, with the presentation of a valid certificate from the National Organization of Standards of Iran and the Technical and Professional Organization of the country.  

 3- Providing quantitative and qualitative monitoring services to production units of refineries, oil pipelines, private sector of free zones and industrial towns with a reliable contract. 

4- Preparing and compiling the formulation of petroleum materials and automotive and industrial oils, according to the nature of the products and increasing the quality of the products in a standardized and reliable manner for export.

 5- Consulting and presenting the sweetening process of gas condensate, naphtha and heavy products, according to the international and engineering principles and standards according to the valid contract.

 6- Providing technical and engineering services for oil and abrasive particles analysis (control and troubleshooting of machines (OCM)), analyzing the results and presenting detailed and documented reports to managers.

 7- Designing, consulting and supervision in the construction of mini-refineries and production lines of petroleum products that can be exported to neighboring countries and the Commonwealth of CIS and Standard.

 8- Presenting the formulation and production process of octane booster for imported and domestic naphtha bases and gas condensates to produce gasoline with Euro 4 and Euro 5 standard and providing approval certificate.

 9- Design, manufacture, production and operation of some reliable and usable laboratory equipment in the oil industry and domestic and foreign private sector factories with a guarantee.

 10- Specialized repairs of damaged or disabled laboratory equipment, by experienced petroleum experts with practical experience of performing such devices and calibrating them.

 11- Installation, commissioning and calibration of any used or unused laboratory equipment, new and repaired by well-known and experienced laboratory experts.

 12- Design, manufacture: distillation analysis device (ASTM D86), vacuum distillation (ASTM D1160), flash point device (ASTM D92 & D93) open and closed method, TBN/TAN device. 


In general, each test has its own standards and each standard has its own limitations. Therefore, the activities are accompanied by standard training of ASTM, IP, UOP, DIN and API. fully supports ongoing ASTM petroleum test method standard efforts, helping ensure the consistency and reliability of industry quality and testing standards. some employees are ASTM members.  petroleum labs participate in a variety of ASTM focused round-robin testing programs  helping ensure analytical method quality and reliability. 


personnel participate in ASTM meetings, providing input, and expertise to support the ASTM D02 technical committee standard and committee meetings.ASTM test methods for the full range of petroleum and petroleum refined products are available  on a global organizations. ASTM ( American Society for Testing Materials) test methods are petroleum industry standards, accepted worldwide for quality and reliability &.

Regarding the laboratory activities, the company, while using these experiences, also provides the necessary training.Follow us in the training section.
