A two-reagent assay protocol was used in this system: The first reagent contains TCEP, CABA-phosphate (the enol-phosphate derivative of chloroacetylbenzoic acid), and latex particles coated with Hcy-ABA (the product of alkylation
of Hcy with CABA).
The installation of the water-mitigation system, coupled with the existing Emergency Shut Down (ESD) sys tem and the new IMP, surpass the level of risk-reduction achieved by most other refiners and rank in the top 10% of safety considerations being implemented by the HF alkylation
industry worldwide," says Graham Turner, Caltex engineering manager, who oversaw the upgrades.
The section Existing Alkylation
Process and Waste Management below introduces the process--alkylation
--concentrating on the management of fluoridic waste arising from HF used as catalyst.
Valero Energy Corp, the largest independent US refiner, also may add a 12,500 barrels per day alkylation
unit to its Houston refinery for the same reason.
As this alkylation
method is not widely applied for the preparation of aza-amino acid precursors it required optimization.
of toluene with methanol produces primarily a mixture of xylenes the distribution of which in the product largely depends on the characteristics of the catalyst.
Now we produce two million liters of 100 LL gasoline per day in alkylation
unit of Aban oil refinery, which is a strategic product and is used as fuel by planes and helicopters' Qasemi noted.
Pilot Chemical's proprietary technologies include: alkylation
, sulfonation, sulfation and a number of other specialty operations.
The other route for combining smaller hydrocarbon molecules into larger ones is alkylation
The major project involves the installation of a Vacumm Distillation Unit, Light Olefine Alkylation
Unit, Light Gasoline Isomerization Unit, Gasoline Mixing Unit and Utility System.
Miyoshi's group has previously reported the successful use of metallic strontium to obtain high yields in the alkylation
of aldehydes or imines with alkyl iodides1,2 and dialkylation of esters with alkyl iodides3.
Summary: TEHRAN (FNA)- The first Iranian made alkylation
unit of a gasoline making project came online at Abadan oil refinery.
