Hydrochloric Acid Concentration Control Using Inline Process Refractometers

Hydrochloric Acid, HCL, is a versatile chemical used in a number of industrial chemical processes such as hydrometallurgical processing, chlorine dioxide synthesis, hydrogen production, and petroleum well activation. Hydrochloric Acid is also commonly used in various metal etching and cleaning processes (pickling of steel), masonry cleaning processes, and the production of plastics (such as PVC), polyurethane production, leather tanning, and in food additive processing.  The dilute version of HCL is Muriatic Acid, which was originally called "acidum salis" and "spirits of salt" because it was produced from rock salt in the 15th century.

Measuring the Concentration of Hydrochloric Acid (sometimes referred to as Concentration Density of Hydrochloric Acid) is a critical part of the production process for all applications mentioned above.  It is important to closely monitor the concentration levels of the hydrochloric acid with a high degree of accuracy and reliability. Although Hydrochloric Acid Concentration can be created in excess of 40% (Concentrated Grade), Industrial Grade high concentration HCL is 30-35%, which is most stable for transport and storage, and reduces the loss of HCL to evaporation.  As the concentration lowers, other names for the concentrations exist, such as Muriatic Acid which can range in concentrations of 21-35%.  

Hydrochloric Acid is a prime candidate for concentration measurement through use of its Refractive Index (R.I.).  Unlike Sulfuric Acid, the R.I. for HCL Acid is extremely linear, rising from 0% at 1.333 R.I. to 40% at 1.425 R.I.  

An inline process refractometer is used to monitor the concentration of Hydrochloric Acid level in real time. Based upon the refractive index (R.I.) of a given aqueous solution, the refractometer can determine the HCL concentration of the solution and relay that value in real time for proactive process control.  

The Electron Machine Corporation’s family of inline process refractometers are the ideal instrument for measuring these concentrations. 

Electron Machine Corporation manufactures the MPR E-Scan; a rugged, dependable, accurate, and cost effective in-line refractometer.  Capabilities include 4-20mA and  0-10VDC outputs, a variety of up to 8 internal relays for direct control of a variety of valves, alarms, and warning indicators, as well as the capability of saving up to 99 different recipes each with their own alarms, set-points and controls. The wetted metal of the sensing head is normally made from Tantalum (other alloys are available). The non-wetted parts and the interconnection cable can be Teflon® coated for added protection.

Benefits of Using the MPR E-Scan:

• High precision and durability in extremely corrosive conditions.
• Continuous quality control.
• Hazardous chemical environmental and safety regulation compliance.
• Low maintenance, repeatable operation.

Inline Process Refractometers for Measurement and Control of Sulfuric Acid Concentration in Industrial Applications

Sulfuric Acid (Sulphuric Acid, H2SO4) is a widely used commodity chemical. Because of it's corrosive properties, special attention has to be paid to its handling and storage. Measuring the concentration of Sulfuric Acid (sometimes referred to as Concentration Density of Sulfuric Acid) is a critical part of the production process. Controlling H2SO4 concentration is very important in many industrial applications including the production of fertilizers, oil refinement, chemical processing, mineral processing and wastewater treatment. Maintaining the desired Sulfuric Acid concentration density ensures it's safe handling and ultimately affects product quality. Industrial inline process refractometers provide the best solution for determining and maintaining Sulfuric Acid concentration.

Electron Machine has a white paper that provides more detail on controlling Sulfuric Acid concentration. You can read and download the white paper here.

Industrial Refractometers and Green Liquor Scale Mitigation

Green liquor, a by-product of the kraft process, is the dissolved concentration of sodium sulfide, sodium carbonate, and other compounds in solution. Keeping track of its component concentration is important to the pulp processing cycle. Green liquor scaling, which includes calcite, sodium aluminosilicates, and pirssonite,  is a problem in most kraft process mills and can cause huge maintenance problems and slow production. Understanding the formation of, and potential ways to control, these formations scale is critical for optimal safety and performance.

Industrial inline process refractometers, such as Electron Machine's MPR E-Scan, are used to measure the green liquor dissolved density, or TTA, at two stages in the process: after the green liquor dissolving tank and after the green liquor clarifier. The inline measurement, with the refractometer sensing head mounted directly in the main process lines, allows real-time control of green liquor dilution to meet target TTA set-points. The measurement is also used to indicate (and prevent) excessive green liquor density and the resulting dangerous impending crystallization within the dissolving tank, and lower the potential for scaling.

Refractometer Optical Sensor Cleaning System 

Refractometer operating conditions must be optimized for close monitoring and control of green liquor density. Consideration of scale and coating build-up on the optical sensor on the refractometer sensing head is a primary area of concern. A clean sensing head will allow maximum accuracy of the refractometer,  maintaining tight density control, minimize scaling, and increasing kraft process quality.

With overall quality and safety in mind, the use of a refractometer sensing head cleaning system is compulsory. The use of ancillary inline cleaning systems, such as Electron Machine's HPC-2 High Pressure Cleaner, that use pressurized water heated to the process temperature, will clean the refractometer optical components and therefore mitigate scaling issues and the related quality, safety, and production problems in the kraft process.

Common Applications for Inline Process Refractometers in Everyday Products

Process refractometers are used in many applications, across a wide variety of industries today. These digital electronic instruments are used to measure dissolved solids and percent concentration in many common, and not-so-common, products.

Using a Spool Adapter with Your Inline Process Refractometer

Two versions of inline refractometer adapters.

Inline refractometers use process adapters as the mechanical connection between the refractometer sensing head and the process piping. The adapter, also referred to as a "spool piece", is designed specifically to accommodate the pipe size and application.

On applications where pipe sizes are 2" or larger, the use of a refractometer sensing head spool adapter is suggested. This ancillary piece of hardware provides a mounting point for the sensing head between two flanges directly in the process piping.

The spool adapter positions the sensing head so that it measures from the center of the process flow. The spool adapter design includes an internal deflector and a 5 degree (angular) sensing head mounting connection. The deflector and angled mounting connection reduces sensor head coating issues from the process media. A steam purge tube connection is standardly included to accommodate steam/fluid cleaning.

Spool adapter with sensing
head mounted.

Spool adapters recommended mounting orientation is horizontal, generally placed in a horizontal segment of process piping. Vertical mounting is also acceptable, as long as the process flow is in an upward direction.

Spool adapter with hand
cleaning option.

Inline refractometer spool adapters are available with option to facilitate cleaning, service and process protection. Examples are lined adapters, hand cleaner adapters, high pressure cleaner adapters, isolation valves, sanitary connection adapters, and weld-in adapters.

BLRBAC Recommended Good Practice Document: Thermal Oxidation of Waste Streams in Black Liquor Recovery Boilers

The black liquor recovery boiler presents problems of operation and safety that far exceed those of the conventional power boiler or other forms of combustion equipment that can be used for the thermal oxidation of waste streams. The recovery boiler is primarily a chemical recovery process unit in which organic materials in the black liquor are burned while the oxidized sulfur compounds of sodium and potassium are reduced and drained as molten smelt from the furnace bottom. At the same time, the heat released is used for generation of steam for power and process.

This document is intended to address concerns of the industry relating to safe thermal oxidation of waste streams in recovery boilers. “Waste streams” for this document are produced in the pulping process. The major waste stream is noncondensible gases (NCG), which are gases that contain reduced sulfur compounds from the digester and evaporator operations and are a source of odor.

The following list is representative of the pulping process waste streams that are addressed:

• Dilute Noncondensible Gas (DNCG)
• Concentrated Noncondensible Gas (CNCG)
• Stripper Off Gas (SOG)
• Chip Bin Noncondensible Gas (CBNCG)
• Dissolving Tank Vent Gas (DTVG)
• Soap
• Methanol
• Turpentine
• Tall Oil
• Spent Acid
• Secondary Sludge

The Three Major Causes of Refractometer Trouble in Black Liquor Recovery Boilers

Pulp and paper mill.

The three major causes of refractometer trouble or failure in black liquor recovery boilers are:

1. Loss of cooling water and its effect on the sensing head.
2. Lack of reliability of the prism wash.
3. Condensation in the sensing head.

These may not apply to all refractometers due to differences in construction and circuitry.

Cooling Water Loss

It is of vital importance that the loss of cooling water be detected. This may be done through a temperature sensing element or flow monitor which shuts down the refractometer involved.

Damage to the sensing element of a refractometer does not occur instantaneously, but it is essential that the system detect abnormal temperatures due to cooling water loss, flow blockage, etc., and that the cooling water be promptly restored.

The individual refractometer manufacturer’s instruction and maintenance manuals shall be consulted with reference to: potential damage to the sensing element; identification of a damaged element; how and when to replace a damaged element.

Prism Wash

The time interval between prism washes may vary with the black liquor composition. It is recommended that the minimum wash period be 7-10 seconds of wash every 20 minutes. Short duration washes at more frequent intervals are more effective than long washes at long intervals. Ideally, steam pressure for prism washing should be 35 psig above the black liquor pressure, plus the pressure required to open the protective check valve.

Awareness must be maintained of the effect of changes to the prism wash programming variables. Various refractometer systems have the capability to adjust: condensate drain time, steam on time, recovery time and interval between wash time. It may be possible to configure the system to have the total time that both refractometers are in their wash cycle represent a significant percentage of operating time. If one refractometer is out of service for repairs and the remaining refractometer is in prism wash, black liquor solids are not being monitored. Prism wash should be minimized to that needed to maintain the system.

If high pressure steam is used, it may abrade the prism. If only high pressure steam is available, a reducing valve shall be used.

The refractometer prism must have a clear polished optical surface, and if it becomes abraded, it must be replaced.

If the prism wash system has not operated properly and the prism becomes coated, it must be removed and properly cleaned.

Condensation in Sensing Head

Condensate may build up in the refractometer sensing head and if this occurs, the instrument operation will be erratic.

The procedure for determining this condition and for the elimination of excessive moisture in the sensing head is not the same for all refractometers. The manufacturer’s instruction and maintenance manuals shall be consulted and followed carefully.

The Basics of Process Refractometers

A refractometer is a process instrument capable of determining a solution's refractive index. Light bends and changes velocity as it travels from one media into another through the media interface. When light traveling through air enters liquid, the light rays change direction by an amount determined by the liquid's density.

Angle of refraction refers to the magnitude the light bends as it exits one media and enters the interface of another. With the angle of refraction defined by their densities, different liquids display different amounts of refraction - for example, a higher density juice such as orange juice will have significantly different refraction than cranberry juice, because of its higher density.

Light bends when traveling through
different media. That's why this pencil
appears to be "broken" when it enters
the water.

A liquid's refractive index relates to the amount of light bending that liquid displays. The greater the bending, the greater the refractive index. The lower the bending, the lower the refractive index.

Standard tables are available that correlate refractive index to a variety of materials. These same tables also correlate refractive index to varying concentrations of particular liquid media at a particular temperature. Take corn syrup for example. Different refractive indexes are observed for different corn syrup samples of different concentrations. Therefore, by using a process refractometer to observe the refractive index of a particular corn syrup sample, a determination of the concentration of that particular sample can be made. By referring to the table or scale that correlates the refractive index to concentration at a particular fixed temperature, liquid concentration can be determined.

The refraction index of the liquid medium readings will vary at different temperatures, and therefore, the sample's temperature must be measured and compensated for in order for refractive index readings to be accurate and repeatable.

Refractive index measurements have been used for process control in the food, juice and beverage industries for decades, with the most common applications being the measurement of sugars (Brix) and total dissolved solids (TDS). Large scale production and processing of fruit juices, jams, tomato products, wine, beer, coffee, and many other products rely on industrial refractometers for quality and consistency.
