INTRODUCTION:
JDL Design offers integrated solutions for various applications such
as compliance monitoring, process control, etc. The system concept is based on
the DAHS and PLC arrangement with specifically designed software to coordinate
communications with all system components in order to meet all criteria of the
EPA regulations. Open-architecture software and state-of-the-art equipment
provide great flexibility, thus insuring certifications and meeting monitoring
needs of SCAQMD RECLAIM DAHS/RTU 2011 &2012, SCAQMD 218 & 218.1, EPA CFR 40 parts 60 & 75 and other
applicable regulatory requirements.

SYSTEM OVERVIEW:
EDR file generation is performed using the InfogenEPAXML software module. This module also handles the RATA and other test results
entry.This package runs concurrently
with the control package so that users may print historical reports from any
data in the database.
JDL Design is now offering our 3rd generation software code name ECMPS XML embracing XML technology to meet the latest requirements by the EPA Acid Rain program. All EDR reports must be 100% XML compliant by the first quarter of 2008.
FUNCTIONAL DESCRIPTION:
PROBE. The sample probe consists of a flange, probe tube,
exchangeable filter element, self-limited heater with low temperature alarm,
and isolated inlets for the purge air and calibration gas. The sample probe
design allows for 1) the purge filter and sample tube with high-pressure
instrument air to blow off particulates that may restrict sample flow and 2) the injection the calibration gases into
the probe to provide complete verification of the entire system. The versatile
but low maintenance sample probe can be used for various applications depending
upon the task to be performed. The sample probe housing material and filter
element media are selected to fit each process specification for reliable
operation.
HEATED SAMPLE LINE, VACUUM PUMP AND SAMPLE CONDITIONER. The heated sample line provides stable temperature
transportation for the sample gas to prevent condensation from the sample probe
to the sample conditioner and delivers calibration gases from the calibration
manifold to the sample probe. It consists of several Teflon tubes, heater
elements, thermal insulation, temperature sensors, and messenger wires. The
vacuum pump provides a steady sample flow and pressure to insure maximum
performance and optimum system response time. All parts and surface material in
contact with the sample are always carefully selected to suit each application.
The final sample preparation is completed by using an integrated sample
conditioning system, which consists of a thermoelectric cooler, peristaltic
pump, and moisture detection sensor.
FLOW AND PRESSURE CONTROL SYSTEM. The functions of this system are to provide switching between sample streams, calibration gases, purge air, and local and remote calibration on PLC commands. It consists of a set of flowmeters, gauges, regulators, and manifolds with solenoid valves. The flow diagram always depends on each application and the number of analyzers in the system.
GAS ANALYZERS. The process of the selection of the gas analyzers is based on the rules and regulations of the EPA. High performance, ease of use, low maintenance, reliability, and cost effectiveness are always the aspects by which these analyzers are selected, but the customer’s preferences are taken into consideration at all times.
SYSTEM ENCLOSURE.Several different sizing options are available depending on the needs of the application. The variations include: stand-alone, dual or single bay 19” rack mount cabinet, NEMA-12, -4 or 4X with HVAC, and a wall mounted cabinet with the same NEMA rating. Also it can be in a CEM shelter with HVAC to house the analyzer rack, PLC, DAHS, a workbench for CEM technicians and cylinder racks.
