What does ALK stand for?

CB&I s work on the refinery will include crude and vacuum distillation, fluid catalytic cracker naphtha hydrotreater, diesel hydrotreater, hydrocracker, hydrogen plant, sulfur plant, delayed coker, HF alkylation, C4 isomerization, power generation, and offsites and utilities.

The refinery will shut its gasoline-making fluid catalytic cracker and alkylation units.

The upgrade also added a 200,000 bpd vacuum distillation unit, a 92,000 bpd catalytic cracking unit and a 26,000 bpd alkylation unit.

They begin by describing the fundamentals of integrated process design, then get into specifics by describing case studies relating to process synthesis using the hierarchical approach, synthesis of separator systems, reactor/separation/recycling systems, phenol hydrogenation to cyclohexone, alkylation of benzene by propylene to cumene, vinyl chloride monomer processing, fatty-ester synthesis by catalytic distillation, isobutane alkylation, vinyl acetate monomer processing, acrylonitrile by propene ammoxidation, biochemical processes for nitrogen oxide removal, polyvinylchloride manufacturing by suspension polymerization, biodiesel and bioethanol manufacturing.

On May 29, 2003, 20 tonnes of isobutane (LPG), mixed with 150 kg of hydrogen fluoride escaped into the atmosphere from a corroded pipe in the HF alkylation plant.

to determine whether they can increase the capacity of their existing alkylation units.

An electrophilic substitution of a proton on the aromatic ring by a halogenated alkane or olefin can be realized in the presence of a strong Lewis acid, which is known as the Friedel-Crafts alkylation reaction [9].

A key tenet in this chemistry is the ability to achieve selective monoalkylation of 1 to give 2 under mild ("normal") PTC conditions, although a second alkylation to form 3 can be accomplished using stronger basic conditions (5).
