Groupe Laperrière & Verreault Inc., or GL&V as it was often known, went public in June 1986 on the Montreal Exchange. In the early 1990s, a Process Group was created to focus on intellectual property, technology development and replacement plans, and parts for clients of GL&V. Significant growth began in 2000, focused on acquisition ...
If V is a vector space over the field F, the general linear group of V, written GL(V) or Aut(V), is the group of all automorphisms of V, i.e. the set of all bijective linear transformations V → V, together with functional composition as group operation. If V has finite dimension n, then GL(V) and GL(n, F) are isomorphic.
This is a list of oil refineries.The Oil & Gas Journal publishes a worldwide list of refineries annually in a country-by-country tabulation that includes for each refinery: location, crude oil daily processing capacity, and the size of each process unit in the refinery.
In the case where V is of finite dimension n it is common to choose a basis for V and identify GL(V) with GL(n, K), the group of invertible matrices on the field K. If G is a topological group and V is a topological vector space , a continuous representation of G on V is a representation ρ such that the application Φ : G × V → V defined by ...
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
Refiners are feeling the pinch across multiple segments of their renewable fuels businesses. Independent refiner Valero's renewable diesel margins in the first quarter fell 21.5% year-on-year to ...
The following year, the company expanded its operations by purchasing the Paulsboro Refinery in New Jersey from Mobil, making it the second-largest independent refiner in the U.S. [10] In 2000, Valero purchased the Benicia, California, refinery and interest in 350 Exxon-branded service stations in California, mainly in the San Francisco Bay ...
As oil production increased, the oil shale refiners discovered that their refining process worked just as well with petroleum, and that petroleum was a cheaper raw material than shale oil. In 1861, the existing oil shale refiners switched to petroleum feedstock, and the oil shale mines shut down.
