HYDROFLUORIC ACID

 


Chemical

Hydrofluoric acid is a colourless fluid with a strong acrid or pungent odour.

It is perhaps best known as an acid which can dissolve glass and certainly many metals, organic and inorganic polymers.

Hydrofluoric acid sits as one of the most dangerous acids due its unique poisoning effect affecting the body calcium balance. Direct contact to the skin of just a palm-sized area can be fatal.

In the fracking and mining industry, hydrofluoric acid is highly controversial due to the residual effects on the land and introduction to ecosystems.

 


Applications

The predominant use of hydrofluoric acid is as a precursor to flourine-based compounds used in products such as ptfe coatings, refrigerants and pharmaceuticals.
In the petrochemical industry, hydrofluoric acid is used as an alkylation catalyst in the production of fuel additives and to increase extraction yields by injecting solutions by dissolving rock to improve conduit flow and access deeper deposits.
Hydrofluoric acid is used to etch and prepare semiconductors, silicon wafers, metals and glass.
Found in rust and stain removal products.
Used in uranium and mineral refining both industrial and in laboratory environments.
Pumping considerations

The key pumping considerations for hydrofluoric acid is its toxicity and chemical compatibility.

Hydrofluoric acid is extremely dangerous and any direct contact with skin or eyes can be catastrophic. The acid quickly penetrates the skin and affects the nervous system so onset of any pain or even knowing the specific fluid has made contact is delayed.

As the acid affects the calcium metabolism and system toxicity as it circulates throughout the body, it can quickly cause cardiac arrest, organ failure and eventually death in hours.

Should a release to atmosphere event occur, the acid can fume and cause a hazardous background vapour which can attack human tissue and the respiratory system.

It is quite clear that the containment of the acid should be first and foremost in the minds any plant manager.

Mag drive containment

A suitable recommendation for a leak-free solution is to install a mag drive centrifugal pump. A mag drive pump eliminates the risk of leakage as there are no wearable mechanical seals around the pump shaft which are at inherent risk of failing. The mag drive pump instead uses an o-ring sealing system for a hermetically sealed unit which is 100% leak-free.

Fitted with a lining of ETFE, a Verdermag U series mag drive pump combines this sealing system and is chemically resistant. A metallic pump may be used such as Hastelloy C-2000/G-30 however many metals are subject to severe corrosion and even more advanced alloys will suffer minor corrosion. Providing the pump is chemically resistant, it will 100% contain the fluid.

 

General Information

Although the chemical formula is a weak acid species with HF, the effects are quite strong. Because of the abrasive effect, they can not be stored in glass bottles. Only low density poly ethylene should be stored in plastic containers. Anhydrous hydrogen fluoride is a liquid stable, colorless, clear and stable at high temperature. Because it is a small molecule and a special acid, it can almost dissolve and pass almost everything. The liquid hydrogen fluoride does not transmit electricity but when it is dissolved in water it ionizes and it can transmit electricity. it can lead to the absorption of the bones by sucking into the body while not giving the feeling of pain as the result of contact with the body.


Molecular Structure

H F


Production and Reactions

Hydrogen fluoride is obtained by treatment of large amounts of calcium fluoride with sulfuric acid.

They are used by reacting with silicon dioxide to form gas or water-soluble silicone fluorides in glass etching processes.
SiO 2 + 4 HF SiF 4 (g) + 2 H 2 OSiO 2 + 6 HF → H 2 SiF 6 + 2 H 2 O
Alkylation with low molecular weight alkenes in the refinement of petroleum, in the presence of a strong acid catalyst derived from isobutane hydrofluoric acid, known as alkylation, provides convenient use.

HİDROFLORİK ASİT

 

Kimyasal

Hidroflorik asit güçlü akrid veya keskin kokusu olan renksiz bir sıvıdır.

Belki de en iyisi, camı ve kesinlikle birçok metali, organik ve inorganik polimeri çözebilen bir asit olarak bilinir.

Hidroflorik asit, vücudun kalsiyum dengesini etkileyen eşsiz zehirlenme etkisinden dolayı en tehlikeli asitlerden biridir. Sadece palmiye büyüklüğünde bir alanın derisine doğrudan temas ölümcül olabilir.

Parçalanma ve madencilik endüstrisinde, hidroflorik asit arazideki kalıcı etkiler ve ekosistemlere giriş nedeniyle son derece tartışmalı.

 

Uygulamalar

Hidroflorik asitin baskın kullanımı, ptfe kaplamaları, soğutkanları ve farmasötik maddeleri gibi ürünlerde kullanılan flourine esaslı bileşiklerin öncüsüdür.
Petrokimyasal endüstride, hidroflorik asit, yakıt katkılarının üretiminde bir alkilasyon katalizörü olarak kullanılır ve kanal akışını iyileştirmek ve daha derin çökeltilere erişmek için kayaları eriterek çözelti enjekte ederek ekstraksiyon verimlerini artırmak için kullanılır.
Hidroflorik asit, yarıiletkenleri, silikonlu gofretleri, metalleri ve camı etch ve hazırlamak için kullanılır.
Pas ve leke çıkarma ürünlerinde bulunur.
Uranyum ve mineral arıtımında hem endüstriyel hem de laboratuar ortamlarında kullanılır.
Pompalama konuları

Hidroflorik asit için önemli pompalama hususları, toksisitesi ve kimyasal uyumluluğudur.

Hidroflorik asit son derece tehlikelidir ve deriyle veya gözlerle doğrudan temas felaket olabilir. Asit cildin derinliklerine hızla nüfuz eder ve sinir sistemini etkiler, bu nedenle ağrı başlamış veya belirli sıvının temas ettiğini bilmesinin geciktirilmesi.

Asit, kalsiyum metabolizmasını ve vücuda dolaşırken sistem toksisitesini etkilerken, hızla kalp durması, organ yetmezliği ve sonuçta saatlerce ölüm neden olabilir.

Atmosfere salınım olayı meydana geldiğinde, asit duman çıkarabilir ve insan dokusuna ve solunum sistemine saldırabilecek tehlikeli bir arka plan buharına neden olabilir.

Asit tutulmasının her şeyden önce herhangi bir bitki müdürü akıllarda olması gerektiğini açıkça belirtmektedir.

Mag sürücünün sınırlandırılması

Sızıntısız bir çözüm için uygun bir öneri, manyetik bir tahrik santrifüj pompası takmaktır. Mag tahrik pompası, sızdırma riskini ortadan kaldırır, çünkü pompa şaftı etrafında, başarısız olma riski taşıyan aşınmaya karşı mekanik keçeler yoktur. Mag tahrik pompası,% 100 sızıntısız hava geçirmez şekilde kapatılmış bir ünite için o-halkalı bir sızdırmazlık sistemi kullanır.

Bir ETFE astarlı olan Verdermag U serisi manyetik pompalar bu sızdırmazlık sistemini birleştirir ve kimyasal olarak dayanıklıdır. Hastelloy C-2000 / G-30 gibi metalik bir pompa kullanılabilir ancak birçok metal ciddi korozyona uğrar ve daha gelişmiş alaşımlar hafif korozyona uğrayacaktır. Pompanın kimyasala dirençli olması,% 100 oranında sıvı içerir.


Genel Bilgi

Kimyasal formülü HF olan zayıf bir asit türü olmasına karşın etkileri oldukça kuvvetlidir.Camı aşındırıcı etkisi olduğundan dolayı, cam şişelerde saklanamazlar. Sadece düşük yoğunluklu poli etilen plastik kaplarda saklanmalıdırlar. Susuz hidrojen florür;akışkan,renksiz,berrak ve yüksek sıcaklıkta kararlı bir sıvıdır.Son derece küçük bir molekul ve ozel bir asit oldugundan dolayi neredeyse herseyi eritip icinden geçebilir.Saf sıvı hidrojen florür elektriği iletmez fakat suda çözündüğü zaman iyonize olur ve elektriği iletebilir.İnsan vücuduna teması sonucunda acı hissi vermezken vücut içine emilerek kemiklerin erimesine yol açabilir.
