Brief Description of Process

WNA Plant
Liquid ammonia is taken from storage tanks and vaporized NH3 evaporator and further superheated in a super heater to 80 deg C. Atmospheric air is compressed to 4.5 kg/cm2 and heated to 200 deg centigrade, ammonia vapor and compressed air are mixed and reacted on Pt-Rh catalyst gauzes to form nitric oxide (NO) and it is highly exothermic. The nitric oxide (NO) is further oxidized to nitrogen dioxide and then absorbed in water to form weak nitric acid (of 60% conc.) and it is also exothermic. The heat of oxidation and absorption is removed by generating steam in the waste heat boiler and cooling water/chilled water circulation, respectively. Tail gas coming from the absorption tower contains traces of NOx’s and these are converted into nitrogen and water vapor in a catalytic converter and vented to the atmosphere after recovering energy in a tail gas turbine. Excess steam is exported to the ammonium nitrate plant.

INTRODUCTION

To set up AN Melt storage tank (30 MT), loading and tanker washing facility from AN Melt plant to the customers by road tankers. Provided basic engineering and detailed engineering for this AN melt storage tank and loading facility. This facility mainly consists of a concentration correction tank, AN melt storage tank, tanker loading & washing area, and associated transfer pumps. The original capacity of the plant was 80TPD (100% basis) each and was increased to 100TPD (WNA plant) and 12TPD (AN plant) in the year 2001.

HAZOP Study
The HAZOP study is a qualitative technique that allows the identification and classification of hazardous scenarios in categories of frequency (.e., likelihood), severity and risk in a specific system with their causes and effects. Safeguards already in place to prevent or mitigate the hazards are then evaluated for their adequacy and whenever necessary/advisable, additional measures to reduce the risks are identified. The HAZOP technique also helps in the identification of situations where plant operability could be compromised.

A total 72 recommendations are proposed for implementation after the HAZOP sessions, and these are recorded in the HAZOP list of recommendations (Annexure D) along with the agency responsible for implementation. The number of recommendations under High Risk (HR), Medium Risk (MR), and Low Risk (LR) are:

SCOPE & OBJECTIVES
The scope of HAZOP study includes the main plants WNA & AN plant along with other utilities like service boiler unit, ammonia (NH3) storage unit and bagging unit. The scope is clearly marked in the P&IDs.

The objectives of the HAZOP study are as follows:

 To identify possible deviations from the design intent.

 Identify potential hazards and operability problems associated with the deviations.

 Review the safeguards provided in the system and their adequacy and recommend additional safeguards, if any.

Recommend actions to eliminate/mitigate the identified hazards and/or operability problems or to identify areas that need to be further investigated.

 

HAZOP PROCESS
The HAZOP Study is a systematic analysis of the Design made through a review of the Piping and Instrumentation Diagrams (P&IDs), developed in order to assess the possible hazards and the operability issues of the system. The methodology relies on a series of guidewords that are applied to each “Node” to identify process deviations and to investigate their impact on Safety and Operability performances. A summary flow chart of the HAZOP process is shown in Figure 6.1

HAZOP WORKSHEETS
The HAZOP worksheet is the findings of the minutes of meeting which provides systematically the logical process and conclusions carried out during the analysis. Worksheets keep accurate record of each situation discovered, either it is potentially hazardous, or impairing plant operations, or jeopardizing equipment integrity or plant operators’ safety.

The HAZOP analysis has been recorded in the Microsoft Excel worksheets. A typical worksheet is composed of the following fields, as shown in Table 6.2. However, the work sheet in the HAZOP
