Introduction

The efficient and reliable operation of sulfur recovery units (SRUs) continues to be critical to hydrocarbon processors, which are tasked with delivering end products that contain lower levels of sulfur while simultaneously reducing the amount of sulfur that is emitted to the local environment. In January 2020, the International Maritime Organization’s initiative to lower pollution from ships – often referred to as IMO 2020 or MARPOL 2020 &nda

If you work in the natural gas industry or are an industrial user of natural gas, water dewpoint is not only a quality measurement but also a big concern. Water condensate presents serious challenges and issues for your process. It is highly corrosive and will form hydrates, which are ice-like solid molecules that can block the flow of gas in pipelines. In cold weather, it will also freeze reducing the pipe pressure.

The history of on-line process analytics is a relatively short one. Development was driven by the need for process control of high value hydrocarbonbased products. The first on-line analyser applications came during the second war. Rapid development came in the 1970s with the advent of the microprocessor and resultant chemometric techniques. Led by Phillips Petroleum, Union Carbide and Dupont Chemical, amongst others, these initiatives were the antecedents of today’s Siemens Applied Aut

Every single interaction between customer and supplier is an oppor-tunity for providing good solutions. After awhile, these positive mo-ments really begin to add up.

Despite the huge effort and extreme consistency required, the best vendors almost re¬ exively deliver useful products and services, and con-tinually develop and release new improvements and innovations. Con-sequently, over months, years and decades, they methodically build reputations for quality, and gain the elus

Abstract

AMETEK THERMOX Introduces the 5th Generation THERMOX Combustion Gas Analyzer in a CONTROL Magazine Exclusive.

WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as well as CO and methane levels.  Information from the Gas Analyzer allows operators to obtain the highest fuel efficiency, while lowering emissions for NOx, CO and CO2.  The zirconium

Abstract

The composition of natural gas varies but consists mainly of methane and varying amounts of heavier aliphatic hydrocarbons, nitrogen and carbon dioxide (CO2).

Cement and Lime Kilns

PROCESS DESCRIPTION
Cement, lime and gypsum manufacturing processes have in common the mixing of inorganic minerals calcined at high temperatures typically using rotary kilns (vertical kilns are also used).

CEMENT
Regular Portland cements are the usual products for general concrete construction. The raw materials, limestone or chalk, together with clay or shale are mixed and fed to a large

For a variety of reasons, decreasing resources are causing plant operators in the process and utility industries to look for more efficient ways of monitoring and servicing their instrumentation. The analyzer maintenance department may have been reduced in size, merged with another department or perhaps no longer exists at all, and reassignments and relocation of staff can lead to a loss of experienced process analyzer operation. At the same time, the importance of the analyzer measurements a

Background
Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings.

In order to address this problem, the analyzer is periodically challenged with a known external
