technical and research personnel and lab facilities , and significantly expanded the portfolio of patents available to us via license and through a cooperative development program .in addition , we have acquired a 20 percent interest in grt , inc .the gtftm technology is protected by an intellectual property protection program .the u.s .has granted 17 patents for the technology , with another 22 pending .worldwide , there are over 300 patents issued or pending , covering over 100 countries including regional and direct foreign filings .another innovative technology that we are developing focuses on reducing the processing and transportation costs of natural gas by artificially creating natural gas hydrates , which are more easily transportable than natural gas in its gaseous form .much like lng , gas hydrates would then be regasified upon delivery to the receiving market .we have an active pilot program in place to test and further develop a proprietary natural gas hydrates manufacturing system .the above discussion of the integrated gas segment contains forward-looking statements with respect to the possible expansion of the lng production facility .factors that could potentially affect the possible expansion of the lng production facility include partner and government approvals , access to sufficient natural gas volumes through exploration or commercial negotiations with other resource owners and access to sufficient regasification capacity .the foregoing factors ( among others ) could cause actual results to differ materially from those set forth in the forward-looking statements .refining , marketing and transportation we have refining , marketing and transportation operations concentrated primarily in the midwest , upper great plains , gulf coast and southeast regions of the u.s .we rank as the fifth largest crude oil refiner in the u.s .and the largest in the midwest .our operations include a seven-plant refining network and an integrated terminal and transportation system which supplies wholesale and marathon-brand customers as well as our own retail operations .our wholly-owned retail marketing subsidiary speedway superamerica llc ( 201cssa 201d ) is the third largest chain of company-owned and -operated retail gasoline and convenience stores in the u.s .and the largest in the midwest .refining we own and operate seven refineries with an aggregate refining capacity of 1.188 million barrels per day ( 201cmmbpd 201d ) of crude oil as of december 31 , 2009 .during 2009 , our refineries processed 957 mbpd of crude oil and 196 mbpd of other charge and blend stocks .the table below sets forth the location and daily crude oil refining capacity of each of our refineries as of december 31 , 2009 .crude oil refining capacity ( thousands of barrels per day ) 2009 .
[['( thousands of barrels per day )', '2009'], ['garyville louisiana', '436'], ['catlettsburg kentucky', '212'], ['robinson illinois', '206'], ['detroit michigan', '106'], ['canton ohio', '78'], ['texas city texas', '76'], ['st . paul park minnesota', '74'], ['total', '1188']]
our refineries include crude oil atmospheric and vacuum distillation , fluid catalytic cracking , catalytic reforming , desulfurization and sulfur recovery units .the refineries process a wide variety of crude oils and produce numerous refined products , ranging from transportation fuels , such as reformulated gasolines , blend- grade gasolines intended for blending with fuel ethanol and ultra-low sulfur diesel fuel , to heavy fuel oil and asphalt .additionally , we manufacture aromatics , cumene , propane , propylene , sulfur and maleic anhydride .our garyville , louisiana , refinery is located along the mississippi river in southeastern louisiana between new orleans and baton rouge .the garyville refinery predominantly processes heavy sour crude oil into products .

Question: what percentage of crude oil refining capacity is located in garyville louisiana?
Answer: 36.7%
