Process Improvement & Protection

Increase your profit through internal process improvement


Petroleum refineries are large and complex production facilities. Once the crude oil price is fixed, the potential refining margin is more or less defined. A small increase in efficiency can drive a significant revenue increase. To maximize this profitability, process efficiency must be optimized and any losses due to corrosion prevented.

The complexity of refining processes makes significant performance improvement without the use of advanced technologies difficult. It is important that a refinery utilizes fast analytical techniques to be able to detect the issues in a process before they cause major problems and losses.

Desalting 

Excessive amounts of chloride salts in crude oil result in higher corrosion rates in refining units and have a detrimental effect on the catalysts used. Desalting techniques are well established, but continuous monitoring of the salt content is needed for process control and cost reduction. Salt in crude oil is determined by titration as per ASTM D6470 or by Conductometric measurement as per ASTM D3230.



Alkylation

Alkylation combines an olefin with butane to produce a higher octane, lower vapor pressure product for blending. It is used in combination with fractional distillation, catalytic cracking, and isomerization to increase yields of automotive gasoline. Either sulfuric or hydrofluoric acid is used as the catalyst for the alkylation reaction. Produced alkylates are passed through caustic to remove the residual acids. Monitoring of acid and caustic concentration are critical in this process.
