Claim 18:
19. An olefin conversion system configured for controlled manufacturing of olefin trimers and olefin tetramers, the olefin conversion system comprising:
a. a first reactor unit configured to receive an acid catalyst;
b. a second reactor unit configured to receive an acid catalyst;
c. a first distillation column configured to separate olefin monomers from olefin dimers;
d. a second distillation column configured to separate olefin dimers from olefin trimers and olefin tetramers;
e. at least one first reactor unit feed line in fluid connection with the first reactor unit and at least one reservoir for olefin monomers;
f. a first reactor unit outlet stream line in fluid connection with the first reactor unit and the first distillation column;
g. a first recycle line in fluid connection with the first reactor unit and the first distillation column;
h. a first bottom product line in fluid connection with the first distillation column and the second reactor unit;
i. a second reactor outlet stream line in fluid connection with the second reactor unit and the second distillation column;
j. a second recycle line in fluid connection with the second distillation column, the first reaction unit, and the second reaction unit;
k. a second bottom product line in fluid connection with the second distillation column and a reservoir for an end product;
l. an optional third distillation column configured to separate olefin trimers from olefin tetramers and including a third column feed line in fluid connection with the second bottom product line; and
m. an optional solvent make-up line connected to the first reactor unit feed line.
