Acid coolers (heat exchangers) and the alkylation
reactor/settler unit are elevated above the secure storage tank.
This section gives an overview of the alkylation
unit to establish the main process characteristics and objectives and to identify the causes of fluorine losses.
It was also found that solvent played an important role in the alkylation
P-ZSM-5-surf-170 are suitable catalysts for alkylation
of toluene with methanol and 2-propanol, respectively.
plants raise safety concerns (all those hot combustible gases mixed strong acids have occasionally been responsible for fires, explosions and toxic clouds).
The 1-alkylimidazoles and pyridine compounds have proven to be good precursors for the development of alkylation
ILs (Wasserscheid & Welton 2003).
A number of environmental toxins and chemotherapy drugs are alkylation
agents that can attack DNA.

West Coast spot market trade sources said the alkylation
unit was shut at the refinery.
Operators told Cal/OSHA investigators they were afraid to operate the alkylation
6 million) investment would include a 24,000-bpd gasoline hydrodesulphurisation (HDS) and alkylation
unit to produce high-quality gasoline, it said.
Basic engineering and process technology were being supplied by Scientific Design (US) for the ethylene glycol and ethylene oxide units, Himont (US) for the polypropylene unit, BP Chemicals (UK) for the polyethylene unit, TEC of Japan for the SBR, PBR, ABS and SAN units, TEC/Nippon Zeon for the butadiene unit, Institut Franais du Petrole for the butene-1 and MTBE units, and UOP (US) for the aromatics plant and the alkylation
and polymer gasoline units.
