TITLE :LIQUID NITROGEN AS A NON- POLLUTING FUEL
ABSTRACT:
Our paper examines the capability of several energy conversion process to provide sufficient energy in a world where the non-renewable resource are getting depleted. Moreover pollution caused by them is increasing at a rapid rate. One such efficient and non-polluting means of running the vehicles is the use of liquid nitrogen. To use liquid nitrogen as a non-polluting fuel, a multiple reheat open Rankine and a closed Brayton cycle are used.

REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES

INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced.

Mechanism of NOx Formation in Diesel Engines.

A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. The engine works by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary engine.
Liquid nitrogen propulsion may also be incorporated in hybrid systems, e.g., battery electric propulsion and fuel tanks to recharge the batteries. This kind of system is called a hybrid liquid nitrogen-electric propulsion. Additionally, regenerative braking can ....etc

NITROGEN±ALKALINITY INTERACTIONS IN THE HIGHLY
POLLUTED SCHELDT BASIN (BELGIUM)



Abstract

We present results of one year observations in highly heterotrophic and oxygen-depleted rivers
of the polluted Scheldt basin. Monthly measurements revealed a high variability for dissolved inorganic
carbon and nitrogen, with the following strong parallelism: highest alkalinity and NH4
+ were associated
with lowest NO3ÿ and oxygen and vice-versa. In river water incubations, nitri®cation lowered the alkalinity
