This commercial item description (CID) covers two types of nitrogen: gaseous and liquid. Each type of nitrogen can be obtained in three different technical grades based primarily on nitrogen and oxygen content. Liquid nitrogen is used as a cooling agent for low...
Agriculture transforms the environment. The simplification of agroecosystems structure increases the hazards of leaching, wind and water erosion, and volatilization of chemicals from soil. Soil nitrogen is of interest as a major crop nutrient, but also as a potential environmental pollutant....
Preface Rice is a staple food for half of the world population. Its total production is next to wheat production. Rice is very much consumed in Asian countries. Hence, cultivation of rice is extensive in these countries. Though the land area under rice is decreasing slowly, the productivity is to...
This specification covers the requirements for three grades and two types of nitrogen.
CONTENTS PART ONE GENERAL CONCEPTS A CASE FOR INTEGRATION I. CHARACTERISTICS OF INTEGRATION IN THE BASIC NITROGEN COMPOUNDS INDUSTRY II. REVIEW OF THE STRUCTURE OF NITROGEN AND ITS COMPOUNDS PART TWO III. GENERAL IV. PRODUCTION OF RAW SYNTHESIS GAS V. PURIFICATION OF RAW...
Not applicable to nitrogen for medical, breathing, electronics applications.
Purpose. This specification covers the requirements for three types of nitrogen tetroxide (N2O4) propellants with separate requirements for procurement and use
Application: B 041 0957 as gas for laser cutting operations B 042 0957 as flushing gas for engines
ISO 25475:2016 specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts or ammonium...
This International Standard specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts...
This European Standard specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts or...
This European Standard specifies a method for the determination of cyanamide nitrogen in fertilizers. The method is applicable to calcium cyanamide and calcium cyanamide/nitrate mixtures.
This publication describes a recommended procedure for nitrogen purging of containers to ensure the safest possible work environment during the nitrogen application process. It also describes protecting the container from hazards associated with exposure to liquid nitrogen.
This method is for determining combined nitrogen in liquefied petroleum gas (LPG), including propylene. The method determines all nitrogen compounds that are extractable by aqueous acid, including ammonia, amines, nitriles and amides. The method is particularly useful for LPG...
