SUBJECT: Organic Liquids Analysis Based on the OLD Data Base 

Purpose 

The purpose of this memo is to present an analysis of surveyed organic liquids, their HAP 

liquid weight percentages, and the reported volumes of the liquids. Crude oil volume and liquid 

HAP percentages were also analyzed. This memo is intended to provide supplemental 

information on the organic liquids surveyed in the 1998 Organic Liquids Distribution industry 

survey. 

Technical Approach 

The Organic Liquids Distribution (OLD) data base was queried for organic liquids, their 

HAP contents (percentage by weight in the liquid), and their throughputs as reported for storage 

tanks. Vapor weight percent information was not queried due to the small amount of data 

received from survey respondents. Storage tank throughputs were chosen because they are more 

comprehensive in the data base than transfer rack throughput numbers. 

HAP liquid weight percent information was ordered into ranges of 10 percentage units. 

Furthermore, once it was determined that the bulk of liquids were in the 0-10 and 90-100 percent 

ranges, these two ranges were individually broken out in units of 2. Charts were prepared to 

graphically depict all relevant findings of the analysis. 

Since it was clear from the data that crude oil forms a large volume percentage of the low 

HAP liquids, an analysis was also performed by removing crude oil HAP percentages and 

volumes. This was done to quantify the effect that crude oil has on the organic liquid profiles. 

Confidential business information (CBI) is contained in the data tables that were used for 

this analysis. The information presented in this memo has been organized so as not to 

compromise any CBI. 

Results 

The results of the analysis are presented in Tables 1 and 2. These tables reflect the HAP 

weight percent and volume information for all surveyed organic liquids in the data base. Charts 

1 through 6 graphically represent the nature of the liquids reported for the OLD industry.

Liquid Occurrence Ranked by HAP Liquid Weight Percent 

There are 1,385 different liquids reported in the OLD data base, 308 of which contain less 

than 10 percent HAP by weight. This represents the second largest number of liquids in any of 

the ranges examined. Interestingly, of these 308 liquids, 222 have less than 5 percent HAP. The 

90-100 percent range contains 675 liquids (49 percent of total), which is the highest number of 

liquid occurrences in all ranges. These two categories together account for over 71 percent of all 

liquids, leaving approximately 29 percent of liquids containing HAP between the range of 10 and 

90 percent. Chart 1 graphically shows that the majority of liquid types have a HAP liquid weight 

percentage between 90 and 100 percent. Chart 1 also graphically depicts the 0-10 percent range, 

which accounts for the second highest occurrence of organic liquids. 

Organic Liquids Ranked by HAP Weight Percent and Volume 

Referring to Chart 2, it is apparent that the largest total volume \s represented by liquids 

which have less than 10 percent HAP. This is primarily due to the presence of crude oil reported 

by Alyeska Pipeline Service Company. Alyeska's crude oil has less than 5 percent HAP, but is 

handled in very large quantities. Over 84 percent of the liquid volume in the 0-10 percent range 

is attributable to crude oil. As a whole, the 0-10 percent range accounts for 67 percent of the 

total reported volume of organic liquids. 

Crude oil also accounts for over 76 percent of the total volume in the 10-19.9 percent 

range. There are no occurrences of crude oil in ranges above 19.9 percent. Above 19.9 percent, 

the predominant liquids are chemicals and petrochemicals. 

Very little liquid volume was reported for liquids having between 20-89.9% HAP. Taken 

together, this range only accounts for approximately 6 percent of the total organic liquid volume. 

Approximately 15 percent of the reported liquid volume containing HAP is located in the 

90-100 percent range. This represents the second largest organic liquid volume in the data base. 

For further reference, Charts 3 and 4 graphically depict the breakdown of the lower and 

upper HAP weight percent ranges (0-20 and 80-100 percent, respectively), in increments of 2 

percent. 

Organic Liquids without Crude Oil 

Table 2 and Charts 5 and 6 depict the distribution of organic liquids with crude oil 

removed. Crude oil accounts for 68.5 percent of the total liquid volume transferred. When 

removed, the largest volume of organic liquids falls into the 90-100 percent HAP category. Most 

of these liquids are pure HAP. The second largest volume of liquids occurs in the range of 0-10 

7^

percent. As evidenced by Chart 6, not much liquid volume is located in between these two 

ranges. 

Conclusions 

The EPA's 1998 organic liquids distribution survey captured a wide array of liquids, 

containing varying amounts of HAP. In the charts presented in this analysis there are two 

primary peaks, one at the low end of the HAP percent range, the other at the top. The peak in the 

low HAP percent range is primarily due to crude oil. In the high range, chemicals tend to 

dominate. There are only a few liquids with HAP percentages between these two ranges. This 

indicates that most of the surveyed organic liquids have either 0-10 percent or 90-100 percent 

HAP. 

The data base contains information on about 20 different crude oils. Though most crude 

oils have low HAP percentages, the volume transferred on an annual basis is very high. As was 

indicated in other memos, the vapor pressure of crude oil can be among the highest of the organic 

liquids in the distribution system. Due to the combination of high volumes handled and high 

vapor pressure exhibited by crude oils, it is reasonable to assume that the HAP emissions 

resulting from the transfer, storage, and distribution of crude oil are substantial. 

It is also apparent that if crude oil is removed from the analysis, a similar volume and 

number of liquids distribution is evidenced at the low and high HAP percentage ranges. This 

indicates that most organic liquids fall into the high and low HAP percentage categories. With or 

without crude oil, the 0-9.99 percent category still contains a large volume of organic liquids that 

have the potential to emit significant amounts of HAP.
