No information concerning the specific production volumes of mineral oil hydraulic fluids was found in the available literature. The National Petroleum Refiners Association (NPRA 1992) reported that 192 million gallons of automatic transmission fluids, universal tractor hydraulic/transmission fluids, energy/ shock absorber and power steering fluids, and other automotive hydraulic fluids were sold in 1991. Virtually all of these fluids are mineral oil hydraulic fluids (Chrisope and Landry 1993 Papay 1989, 1991 Wills 1980). This volume is lower than sales volumes for 1990 (216 million gallons), 1989 (221 million...

The NPRA (National Petroleum Refiners Association) estimates that imposing a 15-ppmw sulfur maximum on diesel could result in a 10% to 20% shortfall in supply . The above trends and discussion indicate that the petroleum refining industry is facing a major challenge to meet the new stricter sulfur speeifieations for produeing ultra elean transportation fuels in the early 21 eentury when the quality of the emde oils continue to deeline in terms of inereased sulfur eontent and deereased API gravity. 

That is, the old back issues of the NPRA Q A (i.e.. The National Petroleum Refiners Associated, Question and Answer) sessions. With this authoritative source as support, 1 asked the operator to stop the NaOH addition to his sour water stripper feed. Two hours later, at the same reboiler duty, the NHj content of the stripped sour water had gone from 0 to about 5 ppm. And the emulsion layer in the crude unit desalter had been reduced enough so that brine carry-over was no longer a problem. The 5 ppm of ammonia was quite acceptable.

The United States Environmental Protection Agency (U.S. EPA), in cooperation with the American Petroleum Institute (API) and the National Petrochemical and Refiners Association (NPRA), has initiated a project to determine the mercury content of crude oil processed in the United States. The focus of the project is to determine the mean concentration and range of concentrations of total mercury in crude oil accurately and with statistical justification. Data generated in the project will be used to calculate the maximum potential contribution of crude oil mercury to anthropogenic mercury emissions in the United States. 

A trade association can play a coordinating role by stipulating that any member has to follow certain rules and r ulations, including the adoption of security measures. For example, the National Association of Chemical Distributors (NACD) has developed a code of responsible distribution, has mandated third-party auditing of code compliance, and has actually terminated membership for noncompliance. Other chemical industry associations such as the American Chemistry Council (ACC), Synthetic Organic Chemical Manufacturers Association (SOCMA), American Petroleum Institute (API), and National Petrochemical and Refiners Association (NPRA) have member codes of conduct and can also play key roles in this regard. 

The participation and cooperation of the American Petroleum Institute (Karin Ritter) and the National Petrochemical and Refiners Association (Norbert Dee) are gratefully acknowledged. The donation of crude oil samples by API and NPRA member companies is sincerely appreciated.
