The Next Generation In Alkylation
Acid Savings One of the highest operational costs in today’s alkylation units
is Sulfuric Acid. Although called a catalyst, the entire amount of catalyst seldom returns to its original state.
Unwanted side reactions consume the catalyst and makeup acid is required to return the reaction to equilibrium.
As today’s refiners test higher contaminant feed stocks, in an effort to counteract the ever increasing crude oil costs, they find their operating expenses suffer from increased sulfuric acid consumption.

Acid Savings
Alky Tech utilizes a revolutionary method to replace the sulfuric acid catalyst resulting in improved acid consumption as well as improved raw material conversion.
Using the Alky Tech Process, acid savings of over 30% have been achieved in 20 MBPD refineries.

Iso / Olefin Ratio Industry average is 8 to 1 or greater Using the Alky Tech Process allows the refiner to
operate successfully at lower I to O ratios.
Many units are isobutane limited.
The Alky Tech Process produces better Isoconversion which results in lower I to O ratios necessary to produce a higher quality Alkyateproduct.

The corollary to acid savings is yield improvement.
If makeup acid requirements are increasing, then yields are decreasing.
It’s because you’re making more undesired side reactions with the raw material and, as such, less alkylate.

If Acid consumption is really the makeup of “diluted” acid, due to side reactions…
Then, by using the AlkyTech process to reduce side reactions…

Throughput Improvement By changing reaction kinetics the Alky Tech Process
allows more raw material to be converted at a faster rate.
Since side reactions are mostly the result of additional time in the reactor, less time means more product and less ASO.
Results from one major West Coast refiner have shown
that production levels can be sustained at up to 30%over face plate ratings with no negative impact on operating conditions using the Alky Tech Process.

Steady State Operations The primary concern of all refiners is safety. When fully optimized, an Alky Tech Process Unit will
allow the operators to have better control of the unit. Spent acid strengths will operate within a much tighter
range, minimizing the swings, and the inherent risks, that are present in most operations.
By steering the reactants through the desired path of alkylate production and away from unwanted ASO production, an Alky Tech Process Unit will have longer run time between planned shut downs.
