The plant has been expanded over the year to 3,400 acres (14 km 2) of land next to the Houston Ship Channel. [ 2 ] The Baytown Refinery is the fifth-largest refinery in the United States by production, after the nearby Port Arthur Refinery .
Scandium-44 (44 Sc) is a radioactive isotope of scandium that decays by positron emission to stable 44 Ca with a half-life of 4.042 hours. 44 Sc can be obtained as a daughter radionuclide of long-lived 44 Ti (t 1/2 60.4 a) from 44 Ti / 44 Sc generator or can be produced by nuclear reaction 44 Ca ( p, n) 44 Sc in small cyclotrons.
Scandium is a chemical element with the symbol Sc and atomic number 21. It is a silvery-white metallic d-block element. Historically, it has been classified as a rare-earth element, [9] together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. [10]
As of December 2017, the plant is the fourth-largest taxpayer [1] and the tenth largest employer [2] in Harris County. The refinery has a 275,000 bbl/d (43,700 m 3 /d) crude processing capacity, [ 3 ] making it the 18th largest in the US, [ 4 ] as of January 2019, with a facility that includes crude & vacuum distillation , delayed coker , fluid ...
At one time, Atofina's headquarters were in an area in Houston close to George Bush Intercontinental Airport and near to the North Houston district.

Naturally occurring scandium (21 Sc) is composed of one stable isotope, 45 Sc. Twenty-seven radioisotopes have been characterized, with the most stable being 46 Sc with a half-life of 83.8 days, 47 Sc with a half-life of 3.35 days, and 48 Sc with a half-life of 43.7 hours and 44 Sc with a half-life of 3.97 hours.
