Testimony - The start-up went very smoothly in 2019

The start-up went very smoothly in 2019, even when the feed flowrate fluctuated between 65% to 105% of the design flowrate. Axens process design is quite robust to face possible start-up and operating troubles.

Testimony - The start-up went very smoothly in 2019

The start-up went very smoothly in 2019, even when the feed flowrate fluctuated between 65% to 105% of the design flowrate. Axens process design is quite robust to face possible start-up and operating troubles. After a week of operation the temperatures were adjusted as per design to 113°C and 120°C for First and Second Reactors respectively. The isomerate RON was above 88, up to 89.2 sometimes, according to our laboratory.

HCl Absorber efficiency was high. C2Cl4 injection was gradually decreased to minimum recommended ratio of Cl/feed but HCl concentration detected in Stabilizer off-gas was still above 5000 ppm. 

Currently we are still very satisfied with Axens ISOM technology and ATIS-2L catalyst. Thanks to the HCl recovery innovation we save 75% of chemicals, and earn 1% isomerate yield more.

Testimony - Axens and Qirun staff worked jointly very satisfactorily to start-up

The unit has been started-up within 6 weeks. Reactors were oiled-in one by one (R-202 on January 2nd and R-203 on January 4th 2019).

Testimony - Axens and Qirun staff worked jointly very satisfactorily to start-up

The unit has been started-up within 6 weeks. Reactors were oiled-in one by one (R-202 on January 2nd and R-203 on January 4th 2019). Then HCl absorber was put in service on January 7th. With HCl absorber, C2Cl4 flow rate was decreased, while HCl content in Stabilizer off-gas remains higher than 3000 ppm.

We believe Chemicals consumption could be saved by more than 75%, but we are currently limited by the minimum turndown flowrate of the selected chloriding agent pump.

Axens and Qirun staff worked jointly very satisfactorily to start-up, operate and follow successfully the unit.

Naphtha Hydrotreating

The Naphtha Hydrotreating process is important to pretreat naphtha for downstream units, like paraffin isomerization and catalytic reforming, where severe specifications are required and catalysts used are very sensitive to impurities. The objective is to reduce sulfur and nitrogen contents (less than 0.5 weight ppm), but also olefins (less than 0.1 weight percent).

Over 200 licenses extensive experience in hydrotreatment of straight run and cracked naphthas.
Optimized operating conditions and energy consumption
Choice of specific catalysts to ensure meeting the products specifications

RAM™

RAM™ processes are proposed for the many large gas and oil reservoirs containing concentrations of arsenic and mercury as low as ppb (parts per billion - 109), as well as contaminants introduced via transport and storage operations that can damage equipment, poison catalysts and generate environmental problems.

The RAM™ processes provide the ultimate solution, transforming the condensate's value from negative to positive. Considering that most of the production cost is in the feedstock alone and that adding a simple process has minimum impact on the overall investment schedule, the financial leverage afforded by this process is considerable.

Depending on the types of contaminants present in the feed, the different options of the RAM™ process are as follow:

  • RAM™ II – One step
  • RAM™ II – Two steps
  • RAM™ III
16 RAM™ units have been licensed worldwide
Excellent industrial results
Outstanding return on investment
