The key is always to try to force the emulsion into instability, so that it separates quickly. In\u00a0oil production there are two types of emulsions.<\/p>\n<ul>\n<li style=\"text-align: justify;\">Water in oil emulsions (WIO)<\/li>\n<li style=\"text-align: justify;\">Oil in water emulsions (OIW), or reverse emulsions<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Oil will easily emulsify with water, when the following\u00a0conditions are present:<\/p>\n<ul>\n<li style=\"text-align: justify;\">Energy &#8211; normally pressure drop over the choke or\u00a0valve and mixing in a high shear pump<\/li>\n<li style=\"text-align: justify;\">Emulsifier &#8211; normally a chemical component in the\u00a0oil or other substances such as wax, solids etc.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Separators are designed for separation of oil, gas, and water, but if an emulsion is formed, then the separators will have problems to separate the phases. To help the separation process, we can use the following physical or chemical tools:<\/p>\n<p style=\"text-align: justify;\">Heat<br \/>\nElectrical field<br \/>\nIncreased flow rate in the separator<br \/>\nChemicals (emulsion breaker)<br \/>\nChemicals (flocculants \/ deoilers)<\/p>\n<p style=\"text-align: justify;\"><a href=\"http:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/emultion.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-43\" src=\"http:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/emultion.jpg\" alt=\"emultion\" width=\"153\" height=\"216\" \/><\/a><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"color: #ff6600;\">CORROSION INHIBITOR<\/span><\/h3>\n<p style=\"text-align: justify;\"><strong>Corrosion Control<\/strong><\/p>\n<p style=\"text-align: justify;\">There are several methods used to apply a corrosion inhibitor \u201cdownhole\u201d to control either sweet or sour corrosion.

Gas is produced from gas fields, or it is associated with oil production. The gas will normally be processed in the following way<\/p>\n<ul>\n<li style=\"text-align: justify;\">It is separated from liquids at the separator<\/li>\n<li style=\"text-align: justify;\">NGL and water is removed using the combined effects\u00a0of compression and cooling<\/li>\n<li style=\"text-align: justify;\">Residual water is removed in a glycol contractor tower. Triethylene glycol is normally used, due to its good\u00a0adsorption and regeneration qualities<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Water connected with gas production may contain salt from the reservoir or it may be condensed water from the cooling and expansion processes<\/p>\n<p style=\"text-align: justify;\"><strong>SOUR GAS<\/strong><\/p>\n<p style=\"text-align: justify;\">One definition of sour conditions is when the partial pressure of H2S is over 0.3 kPa\/0.05 psi or more typically 500 ppm H2S @ 100 psi. On the other hand most pipelines in the North Sea have a limit of 2-3 ppm H2S in the gas. H2S is normally removed by adsorption in amine process, or by the use of non regenerated H2S scavengers. Examples are glyoxal and triazines.<\/p>\n<h3 style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Capability :<\/span><\/h3>\n<ul>\n<li style=\"text-align: justify;\"><strong>Bottle test on site<\/strong>\n<ul>\n<li style=\"text-align: justify;\">Demulsifier \/ Desalter<\/li>\n<li style=\"text-align: justify;\">Water Clarifier<\/li>\n<li style=\"text-align: justify;\">Pour Point Depressant<\/li>\n<\/ul>\n<\/li>\n<li style=\"text-align: justify;\"><strong>Screening product<\/strong><\/li>\n<li style=\"text-align: justify;\"><strong>R &amp; D<\/strong><\/li>\n<li style=\"text-align: justify;\"><strong>Trouble shooting and problem solving<\/strong><\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-47\" src=\"http:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/capability.jpg\" alt=\"capability\" width=\"730\" height=\"560\" srcset=\"https:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/capability.jpg 730w, https:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/capability-300x230.jpg 300w, https:\/\/farcarisa.com\/wp-content\/uploads\/2017\/10\/capability-391x300.jpg 391w\" sizes=\"auto, (max-width: 730px) 100vw, 730px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Service offered : Handling and solving : Emulsion ProblemCorrosion problem Waste water problem Bacteria problem Scale\/fouling problem Sludge problem Oxygen content problem High pour point problem Salt content problem H2S content problem Handling, setting and maintain chemical consumption Chemical dosage optimization Chemical performance monitoring EMULSION Emulsions are defined as one phase dispersed in another, emulsions &hellip; <a href=\"https:\/\/farcarisa.com\/index.php\/chemicals\/oil-production-chemicals\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Oil Production Chemicals<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":869608,"featured_media":0,"parent":19,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-36","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/pages\/36","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/users\/869608"}],"replies":[{"embeddable":true,"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/comments?post=36"}],"version-history":[{"count":11,"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/pages\/36\/revisions"}],"predecessor-version":[{"id":756,"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/pages\/36\/revisions\/756"}],"up":[{"embeddable":true,"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/pages\/19"}],"wp:attachment":[{"href":"https:\/\/farcarisa.com\/index.php\/wp-json\/wp\/v2\/media?parent=36"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
